The purpose of this paper is to examine and analyze whether or not there was a statistically significant reaction in financial markets to the announcements of U.S. defense contractor consolidations (mergers and acquisitions) from January 1990 to December 2006. This analysis is accomplished through the use of two series of event studies, employing first the arithmetic and then the logarithmic returns against the S&P 500 index, involving the top five defense contractors: Boeing, Lockheed Martin, General Dynamics, Raytheon and Northrop Grumman. Many studies have been conducted using the event study methodology, and the results have shown in some cases that stock prices do respond to new information. The assumpton has been maintained that the market responds rationally to such announcements. In contrast, the announcements of the acquisition of publicly traded firms by other publicly traded firms have not always had a consistently significant beneficial effect on the shareholder wealth of the acquiring firms (Schipper & Thompson, 1983). Results of this case study further support the latter assertion, and add to the body of research involving event studies.

Full textAbstract:
This research study investigated intangible assets generated by sport event hosting, specifically in relation to those industries that could influence the planning and leveraging of this alternate value source at Rugby World Cup (RWC) 2015 host destinations. The industries under scrutiny were sport, public sector and tourism, and the sampled host destinations were Cardiff, Exeter, Brighton and Gloucester. The objectives of this thesis were threefold: (1) to respond to the lack of knowledge around the collaborative roles of sport, public sector and tourism organisations in sport event planning, (2) to pioneer representational capital, a concept that looks to examine the input of those pinpointed planners in the identification and valuation of intangible opportunities generated by hosting RWC 2015 fixtures, (3) to probe planning discourse for examples of leveraging representational capital. Expert opinions were captured from executive-level RWC 2015 planners, and supported by secondary data analysis. The findings showed that public sector and sport organisation planning representatives were key RWC 2015 planners and that tourism planners, at a destination level, were not key collaborators in central planning forums, but collaborated extensively with national and international tourism organisations on RWC 2015 planning matters. Additionally, the analysis uncovered that representational capital was predominantly made-up of three key intangible asset areas: destination image, exposure and reputation. Indeed, these intangible areas were recognised and valued by all three industries, but the data analysis indicated that the levels of collaboration between the sampled planning industries did not translate into collectively leveraging representational capital. Moreover, one of the main breakthroughs from this investigation was identifying the interconnected nature of a range of intangible assets in generating greater value, i.e. increasing representational capital available to planners. Representational capital was found to have a strong connection throughout the leveraging process, in terms of the maximisation strategy and planned outputs in RWC 2015 planning, further supporting the study project objective of investigating the intangible in relation to sport events.

Full textAbstract:
The purpose of the thesis is to study share price response to quarterly earnings per share (EPS) announcements in the world steel industry for the last five years (from 2007 to 2011), using the event study methodology. Moreover, the paper attempts to test share price reactions to earnings releases for yearly aggregation (pre-crisis, crisis and post-crisis periods) and countries aggregation (developed and developing countries) of sample steel companies. The research is conducted employing a sample of 30 listed companies, operating in the steel industry. The steel producers’ headquarters are situated in thirteen countries; they are traded on twelve stock markets as primary listing stock exchanges and are referred to thirteen respective indexes.The thesis uses the event study methodology in order to address the purpose of the research. This methodology provides an insight on how numerous corporate events (M&As and takeovers announcements, regulatory changings and earnings announcements) influence company’s stock prices. All the announcements were divided into two groups: “negative” announcements (Group I) and “positive” announcements (Group II). By “negative” announcements it is meant, that new actual earnings per share are smaller than earnings per share from the last quarter, and vice versa for “positive” announcements. The pattern for overall aggregation of sample companies showed the significant and expected share price response to earnings announcements for Group I only. The output for Group II was puzzling. This led to the assumption of negative market perception on the steel industry stock prices as a result of 2007-2008 financial crises. Indeed, for 2007, which was determined as a pre-crisis period for the steel industry, the share price reaction was significant for both groups of EPS announcements. However, within the two other periods (crisis period of 2008-2009 and post-crisis period of 2010-2011) significant and expected pattern was obtained only for Group I once again. The 2007 yearly aggregation comprised only twenty companies due to the data availability. This revealed the assumption, that this sample of twenty steel companies should be tested for the two other periods. However, the pattern remained the same as in the overall aggregation case. Furthermore, the sample steel companies were aggregated on countries basis. The obtained response was analogous to overall aggregation response, the only difference is that Group I reaction was more significant for developed countries than for developing counties sample.

Full textAbstract:
Denna studie syftar till att ge en överblick och förståelse kring hur modeföretag arbetar med varumärkesbyggande via event. Studien syftar också till att undersöka och tillföra en djupare förståelse om varumärken och event som fenomen. Varumärken används ofta av människor för att visa en tillhörighet och ekonomisk status, inte minst inom modebranschen. Den påverkan event har på varumärken har tidigare studerats i förhållande till sportevent, medan forskningen kring modebranschen är begränsad. Detta trots att event ofta förekommer inom modebranschen. Därmed skrivs denna uppsats för att tillföra mer kunskap inom denna forskningslucka. En studie genomfördes baserat på intervjuer med flera modeföretag och varumärkesexperter i Sverige och USA. Svaren från intervjuerna analyserades sedan i förhållande till de valda teorierna som rör både event och varumärken. Teorierna som använts är eventmarknadsföring, varumärkesupplevelse, organisationsidentitet, konsumentbaserat varumärkesvärde och översättningsteori. De resultat som framkom av studien presenteras i en modell med de nyckelfaktorer som framkommit vara viktiga för ett lyckat event. För att besvara frågeställningen är slutsatsen som presenteras att event kan påverka varumärkesbyggande, men vilket sätt det förstärks på är svårt och resurskrävande att mäta. Vid slutet av denna uppsats kommer läsaren att ha en starkare kunskap och förståelse om varumärken och event, samt en övergripande bild kring hur dessa två fenomen är anslutna.This study aims to give an overview and understanding of how the fashion companies are working with brand building through events. The study also aims to examine and provide a deeper understanding of brands and events as phenomenon. Brands are often used by people to show belonging and economic status, not least in the fashion industry. The impact event has on brands has previously been studied in relation to sporting events, while research in the fashion industry is limited. This despite the fact that the events often occur in the fashion industry. Thereby this paper is written to provide more knowledge in this research gap. A study was conducted based on interviews with several fashion companies and brand experts in Sweden and the USA. The responses from the interviews were later analysed in relation to the chosen theories concerning both the events and brands. The theories that have been used are event marketing, brand value, organizational identity, consumer based brand equity and translation theory. The findings from the study are presented in a model with the key factors emerged as important for a successful event. To answer this paper’s question, the conclusion is presented that events can affect brand building, but how it is strengthen is difficult and resource-demanding to measure. By the end of this paper, the reader will have a greater knowledge and understanding of brands and events, as well as an overview of how these two phenomena are connected.

Full textAbstract:
This paper explores how the five largest trading venues in the Nordic region compete after theimplementation of MiFID in November 2007. I investigate: (1) if NASDAQ OMX’s market sharehas increased post the introduction of major changes to its market structure, and (2) how anexchange operator can attract equity share order flow in the near future. By applying event studiesto NASDAQ OMX’s market share over time, I find that introducing a faster trading system andadmitting a high frequency trading firm as a member both have a negative impact on NASDAQOMX’s market share. The reductions in market share can be explained by high frequency tradingfirms’ trading behaviour. Introducing central counterparty clearing has a positive effect onNASDAQ OMX’s market share, which highlights market participants’ appreciation of a securetrading environment, and confirms that it is not only posting the best bid and ask quotes thatattracts order flow to an exchange. It can be concluded that NASDAQ OMX in the future needs toaddress an important trade-off between total turnover and market share, as the two are not alwayspositively correlated.

Full textAbstract:
Several researchers have attempted to understand the destination selection criteria that are important to event planners (Crouch & Ritchie, 1998; Getz, 2003; Oppermann, 1996). However, an examination of the previous studies indicated that only limited understanding of the destination selection criteria has been provided. There is little research that compares event planners belonging to different professional associations and their rating of destination selection criteria. This study examined the differences that exist between three groups of event planners in rating thirteen destination selection variables. The study provides more understanding in the search of an optimal combination of destination selection mix based on multiple dependent variables. This study found significant differences in ratings of five out of thirteen destination selection variables by event planners who were the members of three different associations. Therefore it is providing a valuable contribution to the existing body of literature. From a practical standpoint, this study can help by providing information about how planners of different events feel about certain destination criteria at the time a destination selection is made. All parties with a vested interest in the event industry may use this information to appropriately position their services in the market and tailor their products to better compete for the limited number of events in an environment where the space to host such events continues to grow.M.S.

This study expands on previous research regarding the effect of CEO performance on firm value. An event study is conducted using a market model of CEO successions and daily returns in order to generate predicted returns. Two separate regressions are run using a 3 day and 5 day event window respectively. The results of the regressions are using to compare abnormal returns between industries and market capitalization. While some daily abnormal returns are statistically significant, cross-sectional analysis of CAR are for the most part not significant. Further study is needed in order to come to a stronger conclusion.

Full textAbstract:
In this rapidly changing product demand market, the pharmaceutical companies have adapted their production system to be more flexible and agile. In order to meet the demand, production lines need to be more efficient and effective. Even a small improvement is a great achievement as these production lines are designed to produce large volumes of medicines. To test the efficiency and effectiveness of the lines by analyzing production data would be time taking and needs the involvement of experts from different departments. When production lines are subjected to change, previous analysis done will no longer be valid and needs to be repeated again. Instead, this can be replaced with discrete even simulation analysis (DES). DES is one of the key technology in developing a production system in this industry 4.0 era. As the production systems become more and more complicated it becomes difficult to understand and analyze the behavior of the system if there are any changes brought up in the system. Simulation is the right technology to analyze and understand the behavior of the real system when undergone small or big changes. The purpose of this case study is to make use of DES using ExtenSim as a simulation tool at the case company in order to develop a virtual model of a production system containing five production lines to understand the behavior and analyze the production lines to identify possible improvement and evaluate the feasibility of production system to achieve the forecasted demand. Possible improvements are identified from the simulation results of the current state model and a future state simulation model is developed with the improvements. Furthermore, this future state simulation model is used to analyze the feasibility of production lines for forecasted demand. By developing the simulation model was identified that the production lines were not efficient and are underutilized as that the company assumed.

Thesis, University of Strathclyde, 1997. http://oleg.lib.strath.ac.uk:80/R/?func=dbin-jump-full&object_id=21346.
Full textAbstract:
The large-scale event industry is an ever growing and profitable business, and it is important to the economy of the host country. Based on the proposition that the determinants of an event's success are the quality of (1) its programme, and (2) the facilities and services available for such an event, this study explores the importance of the facilities and services required within venues for large-scale events with respect to the actual users' perceptions. This area has been neglected in the related literature and research. The current research will contribute to the overall knowledge concerning the large-scale event industry, improve the future practices of such an industry, and facilitate further research in this area. The Hajj, i.e. the annual Islamic pilgrimage to Makkah and the Holy Places, Saudi Arabia, is a typical mega-event, and it was used as a vehicle to meet the research objectives. Mega-events involve a large number of diverse population who come from different parts of the world. With regard to this factor a quantitative research approach was employed to collect and analyse the research data, and an exclusive tool (i.e. a questionnaire) to measure the participants' perceptions concerning the importance of facilities and services was constructed. From the results, five indexes were developed to comprise the various aspects and types of facilities and services required within the different Hajj venues. It is found that the types of facilities and services required in a particular venue correlates to the programme taking place in that venue. It is revealed that security and safety are perceived by participants as being a highly important factor required during mega-events. Other facilities and services are also of concern to participants as detailed in the research. It is concluded that both physical (e.g. buildings), and non physical aspects of facilities and services (e.g. appropriate treatment of participants), and the interactions between them, are important, and ought to be considered in further research, as well as in the practices of the large-scale event industry. Six factors are found to have a clear and dominant effect on the participants' perceptions regarding the importance of facilities and services. The factors concern: nationality; verbal communication; participants' age; travelling experience; training and orientation; and resident and non-resident of the host country. The proposition concerning the two determinants of an event's success is supported by the research's findings, and it is argued that beside the programme quality, the success of a mega-event depends mainly on the availability, accessibility, affordability, and presentability of facilities and services. It is revealed that the event industry involves various aspects, including: people; places; environment; processes; and business activities. The most commonly used approaches in managing events do not incorporate these aspects totally. Because the managing of such aspects and the interactions between them is the essence of the facilities management approach, this study proposes that facilities management should be employed in the megaevent industry, and further research is therefore required to assess the performance of facilities management in that area.

Full textAbstract:
Current industrial companies are highly pressured by growing competitiveness and globalization, while striving for increased production effectiveness. Meanwhile, flustered markets and amplified customer demands are causing manufacturers to shift strategy. Hence, international companies are challenged to pursue changes, in order to continue being competitive on global markets. Consequently, a new industrial revolution has taken place, introduced as Industry 4.0. This new concept incorporates organizational improvement and digitalization of current information and data flows. Accomplished by data from embedded systems through connected machines, devices and humans into a combined interface. Thus, companies are given possibilities to improve current production systems, simultaneously saving operational costs and minimizing insufficient production development. Smart Factories, being the foundation of Industry 4.0 results in making more accurate and precise operational decisions from abilities to test industrial changes in a virtual world before real-life implementation. However, in order to assure these functions as intended, enormous amount of data must be collected, analysed and evaluated. The indicated data will aid companies to make more self-aware and automated decisions, resulting in increased effectiveness in production. Thus, the concept will clearly change how operational decisions are made today. Nowadays, Discrete Event Simulation is a commonly applied tool founded on specific data requirements as operational changes can be tested in virtual settings. Accordingly, it is believed that simulation can aid companies that are striving for implementing Industry 4.0. As a result, data requirements between Discrete Event Simulation and Industry 4.0 needs to be established, while detecting the current data gap in operational context. Hence, the purpose of this thesis is to analyse the data requirements of Discrete Event Simulation and Industry 4.0 for improving operational decisions of production systems. In order to justify the purpose, the following research questions has been stated: RQ1: What are the data challenges in existing production systems? RQ2: What data is required for implementing Industry 4.0 in production systems? RQ3: How can data requirements from Discrete Event Simulation benefit operational decisions when implementing Industry 4.0? The research questions were answered by conducting a case study, in collaboration with Scania CV AB. The case study performed observations, interviews and other relevant data collection to accomplish the purpose. In parallel, a literature review focusing on data requirements for operational decisions was compared to the empirical findings. The analysis identified the current data gap in existing production systems, in correlation to Industry 4.0, affecting the accuracy of operational decisions. In addition, it was shown that simulation can undoubtedly give positive outcome for adaptation of Industry 4.0, and a clear insight on data requirements.

Full textAbstract:
Thesis (MTech (Tourism and Hospitality Management))--Cape Peninsula University of Technology, 2008.Research shows that Cape Town has become one of the most popular and prestigious destinations to visit and has opened its doors to minor and major events worldwide. Successful annual events that have become established in Cape Town, nationally and internationally, include events such as the Cape Town International Jazz Festival, Cape Outdoor Adventure and Travel show, Community Chest Carnival, Design Indaba, Design for Living, Homemakers Expo, Cape Argus Cycle Tour, as well as the Old Mutual Two Oceans Marathon and the Cape Town International Kite Festival. Venues such as the Cape Town International Convention Centre have become an international trademark and host large events such as the World Diabetes Conference. These events and venues have placed Cape Town in the world’s top ten destinations to visit. Cape Town is currently preparing for the 2010 Soccer World Cup which places much focus on Risk Management and Compliance. Risk Management concerns predictions and preventions and is described as a process of continuous improvement, which is directed towards effective management of potential opportunities and adverse effects that would impact the event. Risk management plays an important role in the planning and organising of these major events. The aim of this study has determined what the common risks were that event stakeholders within the City of Cape Town have found difficult to manage and have regularly encountered. Risk Management has become one of the most important operational domains within the Event Industry within Cape Town, as well as on a global scale. Since Cape Town has become a global player within the events arena, in terms of major events, much focus has been on risk responsibility and accountability.

More dynamic markets, shorter product life cycles and comprehensive variant management are challenges that dominate today's market. These maxims apply to the automotive sector, which is currently highly exposed to trade wars, changing mobility patterns and the emergence of new technologies and competitors. To meet these challenges, this thesis presents the creation of a digital twin of an existing production line of electric motors using discrete event simulation. Based on a detailed literature research, a step-by-step establishment of the simulation model of the production line using the software Plant Simulation is presented and argued. Finally, different experiments are carried out with the created model to show how a production line can be examined and optimized by means ofsimulation using different parameters. Within the scope of the different experiments regarding the number of workpiece carriers, number of operators as well as buffer sizes, the line was examined concerning the increase of the output. Furthermore, the simulation model was used to make decisions for future investments in additional XXX machines. Four different scenarios were examined and optimized. By examining the different parameters, optimization potentials of XXX% in the first scenario and up to XXX% in the fourth scenario were achieved. Finally, it was proven that the developed simulation model can be used as a tool for optimizing an existing production line and can generate useful investment information. Beyond that, the development of the simulation model can be employed to investigate further business questions at hand for the specific production line in question.Mer dynamiska marknader, kortare produktlivscykler och omfattande varianthantering är utmaningar som dominerar dagens marknad. Dessa maximer gäller bilindustrin, som för närvarande är mycket utsatt för handelskrig, förändrade rörlighetsmönster och framväxten av ny teknik och nya konkurrenter. För att möta dessa utmaningar innebär denna avhandling skapandet av en digital tvilling av en befintlig produktionslinje av elmotorer med diskret händelsesimulering. Baserat på en detaljerad litteraturforskning presenteras och argumenteras en steg-för-steg-etablering av simuleringsmodellen för produktionslinjen med hjälp av programvaran Plant Simulation. Slutligen utförs olika experiment med den skapade modellen för att visa hur en produktionslinje kan undersökas och optimeras med hjälp av simulering med hjälp av olika parametrar. Inom ramen för de olika experimenten när det gäller antalet arbetsstyckesbärare, antalet operatörer samt buffertstorlekar undersöktes linjen om ökningen av produktionen. Dessutom användes simuleringsmodellen för att fatta beslut för framtida investeringar i ytterligare hårnålsmaskiner. Fyra olika scenarier undersöktes och optimerades. Genom att undersöka de olika parametrarna uppnåddes optimeringspotentialer på XXX % i det första scenariot och upp till XXX % i det fjärde scenariot. Slutligen bevisades det att den utvecklade simuleringsmodellen kan användas som ett verktyg för att optimera en befintlig produktionslinje och kan generera användbar investeringsinformation. Utöver detta kan utvecklingen av simuleringsmodellen användas för att undersöka ytterligare affärsfrågor till hands för den specifika produktionslinjen i fråga.

Studien ska även undersöka skillnaderna mellan att se en match i Behrn Arena och på tv. Frågeställningar: Vad gör Örebro Hockey för arenaupplevelsen i Behrn Arena? Vad kan Örebro Hockey göra för att i framtiden förbättra arenaupplevelsen för publiken? Hur har den historiska utvecklingen av arenaupplevelsen i Behrn Arena sett ut för Örebro Hockey? Vad finns det för skillnader mellan Örebro Hockeys matcharrangemang i Behrn Arena och tv-sändningar av C More? Metod: Studien använder en kvalitativ metod med fallstudiedesign. Det genomförs fyra semistrukturerade intervjuer, varav två görs på Örebro Hockeys kansli, en på restaurang Grodan i Stockholm och en på telefon. Vidare görs två mejlintervjuer med representanter för Örebro Hockey. Det görs även två ostrukturerade observationer: en i Behrn Arena och en under en tv-sänd SHL-match av C More. Resultat och slutsats: För att skapa en bra arenaupplevelse för publiken i Behrn Arena använder Örebro Hockey främst kringarrangemang och temamatcher. För att i framtiden förbättra arenaupplevelsen kan klubben däremot förbättra utbudet av mat och dryck för vanliga åskådare samt öka antalet kassaplatser i arenan. För drygt fem år sedan var det enbart ishockeymatchen som var Örebro Hockeys produkt. Publiksiffrorna i Behrn Arena var låga och det fanns varken alkoholtillstånd eller ett variationsrikt utbud av mat och dryck. Sedan dess har stora förändringar skett och det är idag inte enbart ishockeymatchen som är evenemangets produkt, utan kringarrangemang och temamatcher görs för att öka arenaupplevelsen för åskådarna. För att möjliggöra detta har Örebro Hockeys organisation förändrats och nya tjänster som privatmarknadschef och eventkoordinator har tillkommit. Det är slutligen skillnad mellan att se en match live i Behrn Arena och en tv-sänd match av C More. En tv-sänd match ger åskådaren mycket information, genom exempelvis kommentarer, analyser, repriser och statistik. Detta är svårt att erbjuda åskådaren i arenan, även om Örebro Hockey, exempelvis genom en egen studio med intervjuer, gör närmanden mot det. På plats i Behrn Arena får åskådaren däremot uppleva en stämning som är svår att förmedla via en tv-sändning.The aim of the present thesis is to examine the arena experience of the Swedish Hockey League (SHL) club Örebro Hockey. Örebro Hockey has had the highest spectator coverage in SHL both season 2013/2014 and 2014/2015, reaching 97 % and 99 % of the arena respectively. Of that reason, it is of interest to examine what has made the club that successive. The aim of the thesis is also to examine the differences between a game watched live in Behrn Arena, in the arena of Örebro Hockey, and a televised SHL game. The thesis uses a qualitative research method, with three semi-structured interviews with respondents from Örebro Hockey and also a semi-structured interview with Dan Persson. Two additional email interviews are completed with respondents from Örebro Hockey. Furthermore, two unstructured observations are carried out. The observations are made during a game in Behrn Arena and during a televised game. The conclusion of the thesis is that Örebro Hockey primarily uses special events connected to the actual game and theme games to enhance the arena experience of the spectators. Another important conclusion is that while televised games provide the spectator information that is difficult to obtain in the arena, such as replays, statistics, analysis and interviews, games live in the arena provide the spectator an atmosphere that cannot be experienced in a televised game.

Full textAbstract:
The purpose of this study is to examine the value generated to shareholders due to the announcement of mergers and acquisitions (M&A) in different industries. Only deals between firms in the OECD member countries over the period 2004-2014 are analysed. The value is measured by calculating the cumulative abnormal return for event periods close to the announcement date. Cumulative abnormal returns is often used for measuring the impact of events on a stock price and reflect what investors believe will be the value from resulting synergies to shareholders. Only transactions between target and acquiring companies that are operating in the industrials, financial services, information technology and consumer staples industry are examined. Previous research is used to determine industry conditions affecting value creation and the expected value creation for each of the four industries is determined. This study find that returns for acquirers are distributed around zero percent. The mean cumulative abnormal returns for acquirers are negative for three of the four industries examined. The only positive abnormal return for acquirers is found in the financial services industry. Target firm shareholders receive positive returns in all industries. Target firm shareholders in the consumer staples and industrials industries receive on average statistically significant results above zero percent for a significance level of 5%. These industries have also the highest target returns.

Heavy industries operate equipment having a long life to generate revenue or perform a mission. These industries must invest in the specialized service parts needed to maintain their equipment, because unlike in other industries such as automotive, there is often no aftermarket supplier. If parts are not on the shelf when needed, equipment sits idle while replacements are manufactured. Stock levels are often set to achieve an off-the-shelf fill rate goal using commercial inventory optimization tools, while supply chain performance is instead measured against a speed of service metric such as order fulfillment lead time, the time from order placement to customer receipt. When some parts are more important than others, and shipping delays are accounted for, there is ostensibly little correlation between these two metrics and setting stock levels devolves into an inefficient and expensive guessing game. This thesis resolves the disconnect between stock levels and service metrics performance by linking an existing discrete-event simulation of warehouse operations to a new Monte Carlo demand categorization and metrics simulation, predicting tomorrow's supply chain performance from today's logistics data. The insights gained here through evaluating an industry representative dataset apply generally to supply chains for aftermarket service parts. The simulation predicts that the stocking policy recommended by a simple strategy for inventory segmentation for consumable parts will not achieve the desired service metrics. An internal review board that meets monthly, and a quarterly customer acquisition policy, each degrade performance by imposing a periodic review policy on stock levels developed assuming a continuous review policy. This thesis compares the simple strategy to a sophisticated strategy for inventory segmentation, using simulation to demonstrate that with the latter, metrics can be achieved in one year, inventory investment lowered 20%, and buys for parts in low annual usage categories automated.

Full textAbstract:
The purpose of this research is to examine whether U.S. banks that announced material operational risk loss (oprisk loss) events can still enjoy a lower cost of capital. I use the bank's credit rating as a proxy for the cost of debt capital, and the actual oprisk loss amounts announced by publicly traded U.S. banks for $10 million and over during the period 1998 to 2012 compiled from my own database. I also investigate whether the type of oprisk loss event and business line in which the loss event was incurred matter to credit rating agencies. I perform additional analysis to determine whether a downgrade in a bank's credit rating associated with the announcement of a material oprisk loss amount impacts the bank's reputation. This study focuses on the U.S. banking industry because of the increased market and regulatory scrutiny of oprisk losses; especially during the financial crisis of 2008 to 2010. The logistic analysis shows that banks' announcement of material oprisk loss amount is associated with a decline in credit ratings. The findings did not support the position that the type of loss event and business line in which the loss event was incurred matter to credit rating agencies. The results for the event study show that a downgrade in a bank's credit rating associated with an announcement of a material loss amount has a robust, statistically significant negative stock market reaction. Furthermore, the results reveal that the losses in market value significantly exceed the announced loss amounts associated with credit rating downgrades, indicating reputational loss to the banks. This research was limited to announcements of material oprisk loss amounts by U.S. banks publicly traded on major U.S. stock exchanges. Investigating the impact of announcements of material oprisk loss amounts by financial institutions publicly listed on major stock exchanges worldwide provides an avenue for future research. This study contributes to the literature on operational risk and the cost of debt capital as reflected in credit ratings by providing empirical evidence of the impact of oprisk losses on credit ratings of U.S. banks.

Xu, Zhengyang. "Contagion and Competitive Intra-industry Effects of Default Announcements Evidence from Chinese Bond Market." Scholarship @ Claremont, 2016. http://scholarship.claremont.edu/cmc_theses/1375.
Full textAbstract:
In this paper I analyzed the intra-industry competitive and contagion effect during bond defaults in China. The analysis is performed using bond price, since the Chinese stock market is immature and has incredible amount of volatility. The sample includes 15 cases of default across 10 different industries since 2014, and the cumulative effect of the industry portfolio is positive over 11-day event window (competitive effect) with a t-statistic of 6.22. In addition, I found that SOE defaults overall have a significant positive abnormal return on their industry portfolios during 11-day event window with a t-statistic of 4.72, indicating a competitive effect. In contrast, Non-SOE defaults overall have a significant negative abnormal return on their industry portfolios over 3-day window with a t-statistic of -3.36, showing a contagion effect. But this difference could be due to the characteristics of industries as opposed to the nature of SOE. By analyzing the condition and characteristics of each industry, I found that the significance of abnormal return depends on the level of competition of the industry and the level of information available. In terms of contagion and competitive effect, industries showing a contagion effect offer products that are difficult to differentiate, such as cement and water bottle. Industries showing a competitive effect offer products that are highly specialized and rely heavily on technology innovation, such as the special equipment industry and electric equipment industry.

Thesis, Jönköping University, IHH, Företagsekonomi, 2021. http://urn.kb.se/resolve?urn=urn:nbn:se:hj:diva-53154.
Full textAbstract:
Background: The automotive industry experiences significant challenges such as electric mobility, autonomous cars, smart factories, and ridesharing. Above that, the COVID-19 pandemic did not only affect the global health care system but also caused a disruption that challenged the automotive manufacturing sector and its supply chains. Purpose: The automotive industry was investigated to assess the supply chain resilience during the COVID-19 disruption. Therefore, the supply chain performance along the disruption stages was determined. Also, the usage and value of supply chain resilience measures were explored to characterise the current state of supply chain resilience in the industry. Method: A multiple case study and purposeful sampling were used to gather empirical data. Semi-structured interviews with 21 automotive experts from the Scandinavian and German automotive industry were conducted. A content analysis approach was applied to analyse the primary data. The investigation was supported by a systematic literature review prior to the study and additional company reports as secondary data. Conclusion: The level of supply chain resilience within the automotive industry can be assessed as high. A quick recovery and a corresponding rebound of the production volume can be identified, even though the findings indicate that the COVID-19 disruption also caused a bullwhip effect. To compensate for this effect, agility measures, increased collaboration and information sharing, and risk management were used. Other supply chain resilience measures like technological innovations or sustainability were only used to a limited extent.

Full textAbstract:
The power utilities in Sweden are planning to replace the major part of thenuclear power plants with renewable energy resource by the year 2030. Some ofthe renewable energy resources are intermittent, which may endanger the powersystem stability. A solution to this problem could be increased exibility in theend-users consumption, which is known as demand response. This is a usefultool that can be used to facilitate the large integration of renewable energyresource into the power grid. Therefore, several of the Swedish governmentauthorities have stated that the possibilities for demand response should befurther investigated.During this thesis, a case study is carried out at Volvo Group Truck OperationsPowertrain Productions in Koping, with the purpose of deriving theirtechnical possibilities for DR in the factory. Volvo in Koping mainly producesgearboxes to all trucks within the Volvo Group concern and belongs to the engineeringindustry sector. The engineering industry has previously not beeninvestigated for DR purposes in Sweden. The main goal of the thesis is to derivethe DR capacity of the factory and the associated time parameters. Onlydemand response by shifting the production in time is considered.One production group (Midiblock 2) in the factory is modelled using MixedInteger Linear Programming and the optimization problem is used to minimizethe electricity cost while fullling the production requirements. The optimizationproblem is done on daily basis and the result is binary operating pointsfor CNC-machines. The output from the Mixed Integer Linear Programmingproblem is sent to a discrete event model, which is used to validate the resultsand display the optimal energy consumption.The simulation results indicates that the modelled production group can performa load shift of 270 kWh/h during 4 hours by scheduling production. Duringthe reduction it should be possible to perform actions such as maintenance andchanging settings of machines. If the results are true for the entire factory, theresulting load reduction is 1.35 MWh/h during 4 hours. However, the nancialincentives to perform load reductions are low. Also, Volvo in Koping does nothave any routines to shut-o the CNC-machines and an extensive work is requiredto make a load reduction possible. Resulting in that DR at the factory isat the moment unrealistic. In addition to the possibilities for DR, the possibleeconomic savings by shutting o the CNC-machines when they are not producingunits are also approximated. Volvo in Koping can save a large amount ofenergy and yearly cut the cost by at least 5 000 000 SEK on these actions, whichis also the rst step towards enabling DR in the factory.Elkraftsbolagen i Sverige planerar att ersätta kärnkraftverken med förnybaraenergikällor fram till och med år 2030. Några av de förnybara energikällornaär intermittenta i sin produktion och kan på grund av detta medföra en faraför stabilitet i kraftsystemet. En del av lösningen till detta problem kan varaefterfrågeflexibiltet, vilket innebär att el-användarna är mer flexibla i förbrukningenoch anpassar sig till viss del efter kraftsystemets tillstånd. Efterfrågeflexibiltetär ett användbart verktyg som kan underlätta integreringen av de förnybaraenergikällorna. På grund av detta har era svenska statliga företag sagtatt er undersökning bör genomföras inom området efterfrågeflexibiltet.Under detta arbeta har en fallstudie utförts hos Volvo Group Truck OperationPowertrain Production i Köping. Syftet av fallstudien har varit attundersöka möjligheterna för efterfrågeflexibilitet i fabriken. Volvo i Köping producerartill största dels växellådor till samtliga lastbilar inom Volvo Group koncernenoch de tillhör därför industrisektorn verkstadsindustrier.En produktionsgrupp i fabriken modelleras med hjälp av linjärprogrammeringoch modellen används för att för att minimera elkostnaderna genom att föryttalast i tid och samtidigt uppfylla produktionskraven. Optimeringsproblemetberäknas med elpriser för ett dygn och resultatet av problemet är binära tillståndför CNC-maskinerna i produktionsgruppen. De binära tillstånden skickas tillen diskret modell i Matlab som används för att verifiera produktionskraven ochvisa den resulterande energiförbrukningen för produktionsgruppen.Resultatet visar att det är teoretiskt möjligt att förytta 270 kWh/h underen period på 4 timmar genom att förskjuta produktion i tid. Under produktionsstoppenär det möjligt att genomföra underhåll och att förändring iinställningarna på CNC-maskinerna. Om resultaten skalas upp till hela fabrikenskulle den resulterande lastförflyttningen vara 1.35 MWh/h under 4 timmar.Dock så är de ekonomiska incitamenten låga och lastföryttningen är inteekonomiskt hållbar. Ett ytterligare problem är att Volvo i Köping förtillfälletinte har några rutiner för att stänga av maskinerna. Därför krävs det ett omfattandearbete innan det skulle vara möjligt att genomföra en lastförflyttning.Efterfrågeflexibiltet hos Volvo i Köping är därför orealistiskt. Utöver att undersöka möjligheterna för efterfrågeflexibiltet i fabriken, har en del av arbetetsom mål att undersöka de möjliga energi- och kostnadsbesparingar som skapasav att stänga av CNC-maskinerna när de inte producerar enheter. Arbetet harvisat att Volvo i Köping kan varje är spara 5 000 000 SEK på att stänga avmaskinerna, vilket också är ett första steg mot efterfrågeflexibilitet i fabriken.

Thesis, Uppsala universitet, Företagsekonomiska institutionen, 2017. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-324789.
Full textAbstract:
Consumer marketing scholars keenly emphasize a proposed paradigm shift toward interactive relationships and lived brand experiences. Yet, little has been done to investigate the link between the two. Until now. This study is an attempt to measure the effects of lived brand experiences on consumers’ perceived relationship with a brand, through testing an academically established brand relationship quality model onto the concept of experiential event marketing. Susan Fournier’s (2000) brand relationship quality scale was chosen as the construct to be tested in the experiential event marketing context. It was through a theoretical argumentation hypothesized that the experiential event intervention would produce positive direct effects within the scale, but that these would decline with time. This was consequently tested through a repeated measurement study, set at an experiential food truck event hosted by the Swedish FMCG brand Santa Maria. Respondents were to rank their perceived brand relationship quality with the brand on three different occasions; directly before, directly after, and two weeks after being exposed to the experiential event. This way, not only the immediate effect, but also the effect over time, could be measured. It could be concluded that all but one constructs produced positive direct effects, but only half of them were significant. In all cases but one this effect declined significantly when being measured two weeks afterwards, and went in several cases back at approximately the same level as in the initial measurement. These findings have important implications for both academics and practitioners. Most notably, we argue that the link between lived brand experiences in form of typical FMCG experiential events and strengthened longer-term brand relationship quality can be invalidated.

Full textAbstract:
In order for the companies to be competitive in today’s market, it is vital to adapt quickly to the market trends. The steady shift towards mass customization from mass production has been challenging many industries globally, which demands the use of digital tools and technologies in various areas to improve performance throughout the supply chain processes. One of these areas is short-term scheduling of jobs on the shop floor. Short-term scheduling of jobs plays a very vital role in many production systems. Optimisation of short-term scheduling help the companies in improving their operational Key Performance Indicators (KPIs), thus saving both money and resources. Today’s complex production systems with multiple constraints, system level interactions and the dynamic environment have challenged the traditional static scheduling approaches. These complex production systems require new scheduling approaches which can consider all the dynamics and should be capable of real-time reconfiguring in case of uncertainties in the shop floor. In this thesis, a case study was performed in a steel manufacturing company over the period of five months to validate Discrete Event Simulation (DES) as a tool for short-term scheduling of heavy plates in a dynamic environment. The challenges related to DES for short-term scheduling during model design, development and implement phases were also identified. In addition to this, the requirements to implement DES model for short-term scheduling in a dynamic environment were also discussed. Furthermore, a Systematic Literature Review (SLR) was also conducted to support the empirical findings from the case study. The idea of this study was to generate an optimal schedule by minimizing overall makespan and maximizing resource utilization using DES model. The findings from both SLR and DES model has clearly proven that DES as a digital tool is exceptional for short-term scheduling in a dynamic environment, nevertheless there are still some challenges associated which needs to be investigated further. The same model can also be used for other purposes such as analysing and identifying bottlenecks in the whole production system.För att företagen ska vara konkurrenskraftiga på dagens marknad är det viktigt att snabbt anpassa sig till marknadstrenderna. Vägen mot mass-anpassning från massproduktion har utmanat många industrier globalt, vilket kräver användning av digitala verktyg och tekniker inom olika områden för att förbättra prestandan under hela leveranskedjans processer. Ett av dessa områden är kortsiktig schemaläggning av arbeten på fabriksgolvet. Kortsiktig schemaläggning av arbeten spelar en mycket viktig roll i många produktionssystem. Optimering av kortsiktig schemaläggning hjälper företagen att förbättra sina operativa nyckeltal, vilket sparar både pengar och resurser. Dagens komplexa produktionssystem med flera begränsningar, systemnivåinteraktioner och den dynamiska miljön har utmanat de traditionella statiska schemaläggningsmetoderna. Dessa komplexa produktionssystem kräver nya schemaläggningsmetoder som kan ta hänsyn till all dynamik och bör ha möjligheten att omkonfigurera i realtid vid osäkerheter på fabriksgolvet. I denna avhandling genomfördes en fallstudie i ett ståltillverkningsföretag under fem månader för att validera Diskret händelsestyrd simulering som verktyg för kortsiktig schemaläggning av grovplåtstillverkning i en dynamisk miljö. Utmaningarna relaterade till Diskret händelsestyrd simulering för kortsiktig schemaläggning under modellens design, utveckling och implementeringsfaser identifierades också. Utöver detta diskuteras också kraven för att implementera Diskret händelsestyrd simulering för kortsiktig schemaläggning i en dynamisk miljö. Dessutom genomfördes en systematisk litteraturstudie för att stödja de empiriska resultaten från fallstudien. Tanken med den här studien var att generera ett optimalt schema genom att minimera den totala schemalängden och maximera resursutnyttjandet med hjälp av Diskret händelsestyrd simuleringsmodellen. Resultaten från både den systematiska litteraturöversynen och Diskreta händelse simuleringsmodellen har tydligt bevisat att Diskret händelse simulering som ett digitalt verktyg är exceptionellt för kortsiktig schemaläggning i en dynamisk miljö även om det fortfarande finns några utmaningar som måste undersökas ytterligare. Samma modell kan också användas för andra ändamål som att analysera och identifiera flaskhalsar i hela produktionssystemet.

Full textAbstract:
This thesis presents the work of a master degree project in mechatronics by two students from The Royal Institute of Technology. The project was carried out during spring 2017 in collaboration with Bosch Rexroth Mellansel as part of their desire to improve their operations. It is also in line with the Bosch Groups ambition to lead the development within Industry 4.0. The aim was to investigate the information need on a discrete manufacturing process and how radio-frequency identification (RFID) can be used to cover that need. The background research was made with qualitative methods using a literature review on relevant areas and a case study of Bosch Rexroth Mellansel. A discrete event simulation was created to confirm the possibilities of an RFID tracking system. It acted as a target for what the developed demonstrator should fulfil and was realised through a system of four wireless nodes connected in a mesh network. The plant in Mellansel partially implemented a Bosch standardised RFID system in parallel with the development of the demonstrator, which enabled a comparison of the two systems. The results show that from a tag event, which gives information on what, where and when, it is possible to, in real time, analyse and visualise valuable key performance indicators for a production process. It is also possible to use the data to automate transactions in an enterprise resource system which removes non-value adding activities from an operator while also ensuring consistency in the reporting procedure. The results indicate that benefits can be achieved. However, this requires further quantitative analysis before it can be fully confirmed and be used to push the development of Industry 4.0 forward.Denna rapport presenterar ett examensarbete inom mekatronik av två studenter från Kungliga Tekniska Högskolan. Projektet genomfördes under våren 2017 i samarbete med Bosch Rexroth Mellansel som en del av deras strävan att förbättra sin verksamhet. Det ligger också i linje med Bosch koncernens ambition att leda utvecklingen inom Industri 4.0. Syftet var att undersöka informationsbehovet hos en diskret tillverkningsprocess och hur radio-frequency identification (RFID) kan användas för att täcka detta behov. Bakgrundsstudien gjordes med kvalitativa metoder som litteraturstudie inom relevanta områden och en fallstudie av en produktionsprocess inom Bosch Rexroth Mellansel. En simulering av produktionsprocessen skapades för att bekräfta möjligheterna av att använda ett RFID system för spårning av objekt. Den fungerade som ett mål för vad den utvecklade demonstratorn skulle uppfylla och realiserades genom en prototyp bestående av fyra trådlösa noder samlade i ett mesh nätverk. Parallellt med utvecklingen av demonstratorn gemomförde fabriken i Mellansel en del-implementering av en Bosch-standardiserad RFID lösning, vilket möjliggjorde en jämförelse av de två systemen. Resultaten visar att det från en avläsning av en tag, som ger information om vad, var och när, så är möjligt att i realtid analysera och visualisera värdefulla nyckeltal för en produktionsprocess. Det är också möjligt att använda data för att automatisera transaktioner i ett affärssystem som tar bort icke värdeskapande aktiviteter för operatören och samtidigt säkerställer en standardiserad rapporteringsprocess. Resultaten visar att fördelar kan uppnås men kräver ytterligare kvantitativ analys innan de kan bekräftas till fullo och användas för att driva utvecklingen av Industri 4.0 framåt.

Mestrado em Economia Internacional e Estudos EuropeusEste trabalho pretende responder à seguinte pergunta: Existe um contexto favorável para a criação de um cluster aeronáutico na região de Évora? Neste sentido, esta dissertação teve como finalidade identificar e avaliar as condições existentes na região para a criação deste cluster. Não partiu por isso do pressuposto de que o cluster era uma realidade consolidada. Para a elaboração desta dissertação utilizámos como base metodológica uma aplicação da teoria das vantagens competitivas e caracterizámos o contexto recorrendo a bibliografia, dados públicos e entrevistas com os principais stakeholders. Concluímos que, embora ainda não exista um cluster aeronáutico em Évora, o contexto da região é favorável ao desenvolvimento do mesmo. Este contexto favorável deve-se às condições naturais favoráveis (pré-requisitos), ao investimento da Embraer (evento impulsionador) e ao trabalho já efetuado com vista ao desenvolvimento do cluster (processo de expansão). No entanto, a materialização deste contexto favorável num cluster consolidado está dependente da continuação e reforço das políticas de incentivo ao desenvolvimento do mesmo e sobretudo da atração de mais empresas do setor para a região, permitindo a criação de dinâmicas de competição e cooperação entre estas.
This thesis aims to answer the following question: Is there a favorable context for the creation of an aerospace cluster in the region of Évora? In this sense, this thesis aimed to identify and evaluate the existing conditions in the region for the creation of this cluster. Thus, we didn't accept the assumption that the cluster was a consolidated reality. For the elaboration of this thesis we used as a methodological basis an application of the competitive advantage theory and for the characterization of the context we used bibliography, public data and interviews with key stakeholders. We conclude that, although there is not an aeronautical cluster in Évora, the context in the region is favorable for its development. This favorable context is due to favorable natural conditions (prerequisites), the investment of Embraer (triggering event) and the work already done for the development of the cluster (self-augmenting processes). However, the materialization of this favorable context in a consolidated cluster depends on the continuation and strengthening of policies to encourage the development of it and especially in the attraction of more businesses in the industry for the region, enabling the creation of dynamic competition and cooperation between them.

Full textAbstract:
This study aims to explore how human resource management (HRM) practices are implemented in small organisations in the event and exhibition industry in Cape Town, and to examine to what extent these practices influence these organisations' organisational performance. The researcher followed a qualitative case study research design and utilised a semi-structured interview and Likert scale survey. A review of current academic literature has revealed that small organisations, functioning within a highly pressurised environment, focus more on operational survival than on the organisational management of human resources (HR). The event and exhibition industry in Cape Town is characterised by short bursts of high pressurised projects, with fixed deadlines, high profile clients and intense, irregular work periods. Taking into account the aforementioned factors, it is therefore paramount to examine how these small organisations understand HRM practices, as well as how said practices are implemented amidst the challenges experienced in this industry. Overall, the results suggest a positive association between the prioritisation of HRM practices, the alignment of HRM practices to the business plan and the successful implementation of HRM practices in the ten organisations that participated in this study.

This paper uses event study methodology to present evidence that acquirer announcement effects for mergers and acquisitions (M&A) in the American Media and Entertainment (M&E) industry are insignificant. In order to reach this conclusion, this paper both examines existing literature on the topic and manipulates available data on public companies in the M&E industry. It also uses this data to investigate the extent to which different factors influence the acquirer announcement effects. These factors include: the type of financing used for the deal, recent mega-merger failures in the M&E industry, M&A strategy (expansion vs. diversification), as well as target size, country, and sub- industry. The results show that none of these factors have a significant impact on announcement effects.

Essa dissertação tem como objetivo utilizar a simulação de eventos discretos na análise dos estoques seletivos em processo de cabinas, em uma montadora de veículos comerciais de grande porte instalada no Brasil. A análise e a redução desses estoques seletivos são desejadas, pois o armazenamento de cabinas de caminhões, além de representar um alto custo para a produção, é de difícil controle e de alto risco. O desenvolvimento deste trabalho contribuirá para o conhecimento das dificuldades e benefícios da aplicação da simulação de sistemas discretos em sistemas produtivos de alta complexidade, como são os sistemas de manufatura da indústria automobilística. A análise desse sistema é de significativa dificuldade, devido ao tamanho dos produtos, ao mix de produção, à variabilidade do fluxo das etapas de produção e às diversas variáveis que influem no sistema simultaneamente. A técnica de simulação de eventos discretos foi escolhida por ser a mais indicada para analisar todo o sistema e auxiliar na tomada de decisão. Todo o estudo do sistema, modelagem, verificação, validação, simulação e resultados foram feitos de acordo com procedimentos já sedimentados para o uso da simulação de eventos discretos, de acordo com a bibliografia apresentada. Os resultados mostram a eficiência do método utilizado e propõem um cenário otimizado para o sistema estudado. O estudo foi realizado com a utilização do software de simulação de eventos discretos, Arena® 5.0.This work has the main objective to use the discrete event simulation to analyze the in process cabins selective banks of a commercial vehicle assembler. The analysis and reduction of the selective banks are useful because the storage of cabins represents some production risks, is hard to control and implies in high costs. The developing of this work will contribute to the knowledge of the difficulties and benefits of the use of discrete event simulation applied to high complexity production systems like the automotive industry. The size of the products, the production mix, the throughput variability and the other simultaneous variables turn the storage analysis to a hard level. In this way, the discrete event simulation is the most indicated technique to help the analysis and the decision making. The whole study of the system, the modeling, the validation, the simulation runs and the results were done according to known procedures of using the discrete event simulation, which are mentioned in the references. The presented results show the efficiency of the utilized method and proposed optimized scenery of the studied system. The simulation software Arena 5.0 was used in this study.

Full textAbstract:
In order to pursure both environmental and operational targets to facilitate the sustainable transformation of the organization, manufacturers are increasingly incorporating Lean & Green (L&G) production management approaches. Environmental value stream map (E-VSM), which is one of the most well-known L&G tools, allows manufacturers to systematically document, visualize and analyse both environmental and operational performance indicators for each process within a value stream. E-VSM has caught the attention of AstraZeneca, who are looking to implement L&G tools into their current Lean meanufacturing structure to pursue their sustainability targets in the area of environmental protection. Therefore, there is a need to evaluate whether E-VSM is effective within the context of pharmaceutical manufacturing. In this study, a systematic literature review (SLR) was conducted to explore the incentives, success factors, challenges and expected results of L&G implementation, with a specific focus on E-VSM deployment within continuous improvement (Kaizen) cycles. Subsequently, E-VSM was deployed within a pharmaceutical product value stream in a pilot project case study to generate empirical evidence of the tools effectiveness in this context. Kaizen event prioritization is the process of selecting a limited number of improvement activities to implement out of a larger set based on highest perceived benefits due to resource limitations. This study proposes an E-VSM and Kaizen framework which includes a method for systematic Kaizen event prioritization based on the SLR and case study findings. The results indicate that E-VSM is an effective tool for documentation and visualization of environmental indicators in a pharmaceutical production context. Most notably, by introducing a carbon footprint (CF) indicator and using a lifecycle perspective in the E-VSM, CF assessment was integrated into the tool successfully. The E-VSM led to identification of five Kaizen events that would collectively decrease the CF of the value stream by an estimated 65% if implemented. The E-VSM and Kaizen event prioritization framework relies on using the E-VSM to systematically quantify an environmental performance index and transforming it into criteria for Kaizen event prioritization. Future research is directed towards further systemaizing the Kaizen event prioritization method and validating the full framework in various industries.

Supply Chain Event Management (SCEM) bezeichnet eine Teildisziplin des Supply Chain Management und ist für Unternehmen ein Ansatzpunkt, durch frühzeitige Reaktion auf kritische Ausnahmeereignisse in der Wertschöpfungskette Logistikleistung und -kosten zu optimieren.
Durch Rahmenbedingungen wie bspw. globale Logistikstrukturen, eine hohe Artikelvielfalt und volatile Geschäftsbeziehungen zählt die Modeindustrie zu den Branchen, die für kritische Störereignisse besonders anfällig ist. In diesem Sinne untersucht die vorliegende Dissertation nach einer Beleuchtung der wesentlichen Grundlagen zunächst, inwiefern es in der Modeindustrie tatsächlich einen Bedarf an SCEM-Systemen gibt.
Anknüpfend daran zeigt sie nach einer Darstellung bisheriger SCEM-Architekturkonzepte Gestaltungsmöglichkeiten für eine Systemarchitektur auf, die auf den Designprinzipien der Serviceorientierung beruht. In diesem Rahmen erfolgt u. a. auch die Identifikation SCEM-relevanter Business Services. Die Vorzüge einer serviceorientierten Gestaltung werden detailliert anhand der EPCIS (EPC Information Services)-Spezifikation illustriert.
Abgerundet wird die Arbeit durch eine Betrachtung der Nutzenpotenziale von SCEM-Systemen. Nach einer Darstellung von Ansätzen, welche zur Nutzenbestimmung infrage kommen, wird der Nutzen anhand eines Praxisbeispiels aufgezeigt und fließt zusammen mit den Ergebnissen einer Literaturrecherche in eine Konsolidierung von SCEM-Nutzeffekten. Hierbei wird auch beleuchtet, welche zusätzlichen Vorteile sich für Unternehmen durch eine serviceorientierte Architekturgestaltung bieten.
In der Schlussbetrachtung werden die wesentlichen Erkenntnisse der Arbeit zusammengefasst und in einem Ausblick sowohl beleuchtet, welche Relevanz die Ergebnisse der Arbeit für die Bewältigung künftiger Herausforderungen innehaben als auch welche Anknüpfungspunkte sich für anschließende Forschungsarbeiten ergeben.

Full textAbstract:
Firms today maintain complex supply chains containing many dependent stages to manufacture a product to the end customer. Here lies a dilemma, keeping extensive inventory generate higher customer satisfaction by enabling quick deliveries. This increase in inventory, however, comes at an increase in costs. Finding the balance between minimizing costs and increasing customer satisfaction is difficult. The search to solve this dilemma has led to the development of research in the area of inventory control. For long, optimization models have been developed to improve the supply chain holistically, from raw material-to-customer. Those approaches, however, have not been possible to apply in practice by being too computationally demanding. Also, they imply organizational adjustments that create issues beyond the optimization flow of materials. It explains why, despite significant technolog- ical advancements, many firms prefer to use non-holistic approaches. This thesis evaluates the tangible effect of using holistic optimization. The objective of this thesis’ is to determine optimal stock levels between dif- ferent stages of production. The method used is an optimization of inventory, stemming from Inventory Control Theories. Inventory optimization is at the cross- roads between logistics, economics, and management. The thesis builds on a case of inventory optimization identified at a large manufacturing firm. The literature in inventory optimization has indicated that inventory and customer services is a domain of continuous development. This thesis focuses on the adequation between total inventory cost and the customer service level. The method used to answer this question is the Multi-Echelon optimization model. This model seeks to optimize reorder points and reorder quantities. A comparison to the Single-Echelon model and a Base-Case allows for evaluation of the performance, discrete event simulation based on a company’s supply chain measures the effect. The result shows that the Multi-Echelon optimization model outperforms the two non-holistic models. This thesis shows the triple advantages of the Multi-Echelon optimization allowing for leaner manufacturing system by 1- reduction of waste, 2- less unproductive capi- tal tied up in inventory, and 3- adding value by increasing customer satisfaction. Other areas of inventory optimization in manufacturing should be able to take ad- vantage of the Multi-Echelon optimization model to manage materials stock-levels, delivery flows, and customer satisfaction.Idag bedriver företag komplexa försörjningskedjor med många relaterade produk- tionssteg för att försörja sin efterfrågan. Dilemmat är att antingen ha stora lager för att säkerställa både snabb kundleverans och hög kundnöjdhet vilket kräver mycket bundet kapital. Alternativet är att spara pengar genom mindre lager men riskerar då att inte kunna leverera inom önskad tid och minska kundnöjdheten. Att hitta en balans är svårt. För att lösa problemet har forskning inom området lager- styrning ökat. Optimeringsmodeller har länge utvecklats för att förbättra försör- jningskedjor. De har inte kunnat appliceras i många företag p.g.a. avsaknaden av beräkningskraft och behovet att förändra organisationen utöver optimeringen. Det förklarar varför många företag, trots teknisk utveckling, fortfarande inte an- vänder ett helhetsperspektiv. Denna uppsats utvärderar de påtagliga effekterna vid holistisk optimering av produktion, lagerhållning, och kundleverans. Målet med uppsatsen är att fastställa optimala lagernivåer mellan de olika stegen inom en produktionskedja. Metoden som används är ”Multi-Echelon” op- timering och härstammar från området ”Inventory Control Theories”. Det är en blandning av logistik, ekonomi, och administration. Lageroptimering är ett ämne i konstant utveckling där kundnöjdhet blivit allt viktigare. Modellen optimerar när en ny beställning av material ska ske, samt dess storlek. Modellen utvärderas genom att jämföra prestationen med en ”Single-Echelon” modell och en grund- modell genom diskret händelsesimulering som är baserad på ett företags försör- jningskedja. Resultaten visar att ”Multi-Echelon” optimeringsmodellen presterar bättre än de två icke-holistiska modellerna vad gäller totalkostnad och kundser- vicenivå. Uppsatsen visar att ”Multi-Echelon” optimeringsmodellen har fördelar inom alla tre områdena: smidigare produktion genom mindre spill, mindre bun- det kapital krävs, och den ger en ökad kundnöjdhet genom säkrare leveranser inom ”rätt” tid. Andra områden inom tillverkningsindustrin borde kunna ap- plicera ”Multi-Echelon” optimering för att hantera sina lagernivåer, produktion, leveransflöden, och kundnöjdhet.

Les carteres d'aliances importen? Com afecten els recursos als quals les empreses accedeixen per diverses aliances estratègiques simultànies amb socis diferents a la creació de valor i a l'apropiació de valor? Les carteres d'aliances expliquen l'heterogeneïtat entre empreses respecte del valor que capten quan entren en noves aliances estratègiques? Aquesta tesi doctoral es basa en la teoria dels recursos i en la bibliografia sobre el comportament estratègic i les dinàmiques competitives, i presenta un model teòric que es refereix a la creació de valor i l'apropiació en empreses que accedeixen a recursos a través de diverses aliances simultànies amb socis diferents. El model mostra que la creació de valor en les carteres d'aliances és una funció del valor creat per combinacions sinergètiques de recursos que impliquen recursos als quals tenen accés diferents socis, com també del valor destruït a causa de la incompatibilitat entre la combinació de recursos d'una empresa focal i els recursos dels seus socis. Sobre la base d'aquest model teòric, s'han desenvolupat diverses hipòtesis en un ambient marginal en què una empresa connectada multilateralment afegeix una nova aliança estratègica a la seva cartera d'aliances. Per comprovar aquestes hipòtesis, s'ha emprat la metodologia de l'event study i s'han utilitzat dades de la indústria de els línies aèries globals sobre acords de code share subscrits entre 1994 i 1998. Els resultats mostren que el mercat recompensa les empreses que formen aliances amb socis que tenen recursos complementaris i poden aportar recursos que no només es poden combinar amb els recursos propis de l'empresa sinó també amb els relacionals i que també són compatibles amb els dels socis que formen l'aliança. D'altra banda, els resultats també mostren que el mercat penalitza les empreses que formen aliances que aporten recursos incompatibles amb les carteres d'aliances, atès que creen un conflicte competitiu amb alguns dels socis existents. Els resultats de la part empírica d'aquesta anàlisi abonen la tesis que les carteres d'aliances afecten els resultats de les empreses que entren en aliances estratègiques. Aquest estudi conclou que els recursos als quals es té accés per mitjà d'aliances entre empreses s'han d'avaluar no tan sols per les seves característiques pròpies y diàdiques sinó també en el context de les carteres d'aliances.¿Importan los portafolios de alianzas? ¿Cómo afectan los recursos a los que acceden las empresas por varias alianzas estratégicas simultáneas con socios diferentes a la creación de valor y a la apropiación de valor? Los portafolios de alianzas ¿explican la heterogeneidad entre empresas con respecto al valor que captan cuando entran en nuevas alianzas estratégicas? Esta tesis doctoral se basa en la teoría de los recursos y en la bibliografía sobre el comportamiento estratégico y las dinámicas competitivas, y presenta un modelo teórico que se refiere a la creación de valor y apropiación en empresas que acceden a recursos a través de varias alianzas simultáneas con socios diferentes. El modelo muestra que la creación de valor mediante un portafolio de alianzas es una función del valor creado por combinaciones sinergéticas de recursos que implican recursos a los cuales acceden diferentes socios, así como del valor destruido a causa de la incompatibilidad entre la combinación de recursos de una impresa focal y los recursos de sus socios. Sobre la base de este modelo teórico, se han desarrollado varias hipótesis en un ambiente marginal en el que una empresa conectada multilateralmente añade una nueva alianza estratégica a su cartera de alianzas. Para comprobar estas hipótesis se ha empleado la metodología del event study, y se han utilizado datos de la industria global de las aerolíneas sobre acuerdos de code share suscritos entre 1994 y 1998. Los resultados muestran que el mercado recompensa a las empresas que forman alianzas con socios que tienen recursos complementarios y pueden aportar recursos que no sólo pueden combinarse con los recursos propios de la empresa sino también con los relacionales y que también son compatibles con los de los socios que forman la alianza. Por otra parte, los resultados también muestran que el mercado penaliza a las empresas que forman alianzas que aportan recursos que son incompatibles con los portafolios de alianzas, en el sentido de que crean un conflicto competitivo con algunos de los socios existentes. Los resultados de la parte empírica de este análisis abonan la tesis de que los portafolios de alianzas afectan a los resultados de empresas que entran en alianzas estratégicas. Este estudio concluye que los recursos a los que se accede a través de las alianzas entre empresas han de evaluarse no sólo por sus características propias y diádicas sino también en el contexto de los portafolios de alianzas.
Do alliance portfolios matter? How do resources accessed from multiple simultaneous strategic alliances with different partners affect value creation and value appropriation? Do alliance portfolios explain heterogeneity across firms with respect to the value that they derive from entering into new strategic alliances? This dissertation builds on insights from the resource-based view of the firm and the strategic behaviour and competitive dynamics literature and advances a theoretical model that addresses value creation and appropriation in firms that access resources through multiple simultaneous inter-firm alliances with different partners. The model illustrates that value creation on the alliance portfolio level is a function of the value created from synergistic resource combinations involving resources accessed from different partners as well the value destroyed by incompatibilities between a focal firm's resource combinations and those deployed by its partners. Based on this theoretical model, empirically testable hypotheses are developed in a marginal setting, in which a multilaterally connected firm adds one new strategic alliance to its alliance portfolio. The hypotheses are tested using an event study method approach and data from the global airline industry on code share agreements formed between 1994 and 1998. The results show that the market on one side rewards firms entering into strategic alliances with partners that possess complementary resources and that contribute resources that cannot only be combined with firms' own but also existing relational resources and that are compatible with the firms' alliance portfolios. On the other side, results show that the market penalizes firms entering into alliances that contribute resources that are alliance portfolio incompatible in the sense that they create a competitive conflict with some of the existing alliance partners. The findings of the empirical part of this dissertation support the view that alliance portfolios affect the performance of firms entering into strategic alliances. This study concludes that resources accessed through inter-firm alliances should not only be evaluated on their standalone and dyadic attributes but also in the context of alliance portfolios.

La crise financière liée aux emprunts hypothécaires subprime a mis en lumière aux yeux du public le recours à une technique d'ingénierie financière complexe : la titrisation. Le recours à la titrisation a suivi une croissance exponentielle durant la dernière décennie, la transaction se constituant en tant que moyen de financement privilégié aux Etats-Unis et en Europe. L'objectif de ce travail doctoral est d'apprécier les enjeux que véhicule la titrisation en termes de communication comptable et financière des groupes bancaires cotés, au regard de l'intérêt que confère la transaction quant à la satisfaction des intérêts du dirigeant. La recherche s'organise en deux volets. Le premier vise à déterminer et expliquer l'impact de l'annonce d'une titrisation par les banques sur le cours de leur action. Le second traite des conséquences du choix du dirigeant de structurer la transaction en hors bilan sur les éléments comptables suivants : le taux de rentabilité économique, le taux d'endettement, le ratio de Bâle, et le niveau de risque de crédit. Les résultats de cette étude démontrent que, si le marché réagit négativement à l'annonce de la transaction, le recours à la titrisation, notamment lorsque celle-ci revêt une apparence hors bilan, s'inscrit en adéquation avec les intérêts personnels du dirigeantFinancial crisis due to subprime mortgage loans put in light to public the use of a complex financial engineering technique : the securitization. Recourse to securitization presents an exponential growth during the last decade, as this kind of transaction is nowadays used as the preferential tool of financing in the USA and Europe. This dissertation aims to appreciate issues conveyed by the use of securitization in terms of accounting and financial communication for listed banking groups, taking into account interests brought by this transaction to the manager. This research is made following two steps. The first step aims to determine and explain the impact due to securitization announcement by banks onto share price. The second step deals with consequences of manager's choice to design transaction off-balance sheet on the following accounting items : return on assets, leverage, Basle ratio, and level of credit risk. Results from this research bring to light that, in spite of a negative market perception during the announcement of the transaction, the use of securitization and particularly when it appears as off-balance sheet, is adequate to satisfy manager's own interests

I takt med att teknologin i nytillverkade bilar blir allt mer avancerad, ökar också antalet produktåterkallelserinom bilindustrin till följd av defekta komponenter. En produktåterkallelse ger upphov till enkostnadsökning för det berörda företaget och bör således ge en negativ effekt på aktiekursen, närmarknadsaktörer tar del av informationen. Det är inom bilindustrin vanligt att biltillverkande företagkontrakterar ut tillverkningen av fordonens komponenter. Den upptrappade outsourcingen frambringarfrågan om vilken part som ska ansvara för återkallelsens kostnader.

Studien har valt ut 39 händelser när ett biltillverkande företag tvingas attåterkalla bilmodeller. Uppsatsens resultat visade att produktionsledets olika aktörer inte påverkas avinformation om en återkallelse, därmed gick det inte heller påvisa att komponenttillverkare drabbashårdare än biltillverkare av en återkallelse. Studiens resultat visade heller inget positivt samband mellanmarknadsreaktionen beroende på återkallelsens storlek, felorsak eller tidpunkten för tillkännagivandet.As the technology in newly manufactured cars becomes more advanced, the number of product recallsin the automotive industry is also increasing due to defective components. A product recall gives rise toan increase in costs for the company concerned and should therefore have a negative effect on the shareprice when market participants consult the information. It is common in the automotive industry for carmanufacturing companies to outsource the production of vehicle components. The escalating outsourcingraises the question of which party should be responsible for the costs of the recall. The study examineswith the help of event studies and hypothesis tests how the different actors in the production stage areaffected by information about a recall in the automotive industry? The study has selected 39 events whena car manufacturing company is forced to recall car models. The results of the paper showed that thevarious operators of the production stage are not affected by information about a recall, so it was notpossible to demonstrate that component manufacturers are hit harder than car manufacturers by a recall.Furthermore, the results of the study did not show a positive relationship between the market reaction dueto the size of the recall, the cause of the withdrawal or the time of the announcement.

Full textAbstract:
Background: Previous studies on the subject, contrary to corresponding studies on mergers and acquisitions, have shown significant positive market reactions from all over the world on the announcements of divestitures. However, similar studies have not been done on the Swedish market. There are split opinions on the origin of the abnormal returns from the announcements of divestitures, but the economic cycle, choice of payment method and industry affiliation are recurring explaining variables in event studies. Aim: The aim of the study is to investigate the effect on shareholder wealth from the announcements of a divestiture on the Swedish market during the period from 1997-2017, as well as investigating how the abnormal returns are affected by the economic cycle, choice of payment method and industry affiliation. Completion: The study is conducted using the event study methodology and a deductive approach. Historical time series from divesting companies share prices are used to estimate expected returns which are then compared to actual returns to decide whether the announcement of a divestiture has an impact on shareholder wealth. Results: The study finds significant results that divesting companies’ shareholder wealth are positively affected by the announcement of a divestiture for both event windows (-3, +3) and (-1, +1). For each separate day within the event window the authors find statistically significant returns for day T-2 and T0. The authors find no statistically significant differences between the returns regarding the economic cycle. Regarding the choice of method of payment, it is concluded that payment through stock generates excess returns when compared to other financing alternatives. No differences could be found between different industry affiliations.Bakgrund: Tidigare studier inom ämnet har, till skillnad från motsvarande forskning om företagsförvärv, påvisat signifikanta positiva reaktioner från marknader över hela världen vid tillkännagivandet av en avyttring. Däremot saknas studier om avyttringars effekt på den svenska marknaden. Det råder delade meningar om varför abnormal avkastning uppstår vid tillkännagivandet, där konjunkturläge, finansieringsalternativ och branschtillhörighet är vanligt förekommande förklarande variabler i eventstudier. Syfte: Studiens syfte är att undersöka hur tillkännagivandet av en avyttring påverkar säljande bolags aktiekurs på den svenska marknaden under tidsperioden 1997–2017, samt att undersöka hur rådande konjunkturläge, valt finansieringsalternativ och branschtillhörighet påverkar avkastningen Genomförande: Studien genomförs genom eventstudiemetodologin med en deduktiv ansats. Empirin utgår från historisk tidsseriedata från avyttrande bolags aktiekurser för att bestämma förväntad avkastning som sedan jämförs med faktiskt avkastning för att urskilja om tillkännagivandet påverkar kursutvecklingen. Resultat: Studien visar statistiskt signifikanta resultat för att avyttrande bolags aktiekurs påverkas positivt av tillkännagivandet av en avyttring både för eventfönstret (-3, +3) och (-1, +1). För de enskilda dagarna i eventfönstret finner författarna statistiskt signifikanta avkastningar för dag T-2 och T0.

Realizar a análise econômica de uma produção agropecuária não é algo trivial, seja pela enorme heterogeneidade entre cada unidade produtiva, seja porque utiliza muitos recursos naturais, alguns de difícil mensuração. Há diversos métodos disponíveis para o cálculo do custo de produção, que é o indicador chave para a análise da viabilidade de um empreendimento. O desafio é permitir que a projeção da atividade no horizonte produtivo seja a mais real e dinâmica possível. A simulação computacional é atualmente uma das mais poderosas ferramentas de análise disponível para o planejamento, projeto e controle de sistemas complexos, e vem sendo cada vez mais utilizada e difundida. Simular compreende a elaboração de um método de experimentação que, através da construção de modelos de um sistema real, procura descrever comportamentos, construir teorias ou hipóteses por meio do observado e predizer comportamentos futuros. O uso de modelos de simulação, que incorporem o risco e a probabilidade dentro produção animal, pode ser uma alternativa tanto técnica - auxiliando na tomada de decisão, gestão e planejamento pecuário, quanto científica - permitindo a avaliação de efeitos de resultados da pesquisa e identificação de limitantes que podem incentivar o desenvolvimento de pesquisas futuras. O modelo de simulação híbrido - baseado em simulação de eventos discretos e baseado em agentes, aqui proposto - visou identificar coeficientes zootécnicos e os critérios de manejo que mais impactam a produção de ovinos de corte. Esse modelo de simulação computacional híbrido possui caráter dinâmico e probabilístico, com eventos marcados no tempo (estação de monta, gestação, parição, desmame, engorda, abate, entre outras) e complexos o suficiente para que seus agentes sofram alterações tanto no tempo quanto em resposta a ocorrência ou não das variáveis ligadas a eles. Os resultados dos experimentos e dos cenários estudados revelaram que dentre os índices zootécnicos das matrizes, a ocorrência de aborto gera maior impacto na taxa de abate e financeiramente na margem líquida operacional. Contudo, analisando as variáveis tanto para matrizes como para cordeiros, a mortalidade neonatal, até os cinco dias de vida dos cordeiros, demonstrou ser o ponto fundamental para a lucratividade da atividade. A estabilização do rebanho foi mais afetada pela presença de matrizes adultas no plantel, que culminaram no aumento no número de cordeiros por matriz. Os resultados da análise dos fluxos de caixa de 30 anos, a uma taxa mínima de atratividade de 6,17% aa, permitiram constatar que iniciar a atividade com número muito reduzido de matrizes é o cenário menos interessantes, com taxa interna de retorno negativa para o período de análise. O estudo do fluxo de caixa permitiu atribuir a 200 matrizes como o tamanho de rebanho inicial mais interessante (TIR = 3,30% aa). Assim, o uso de simuladores híbridos baseados em simulação de eventos discretos e baseados em agentes, para estudos na pecuária nacional, apresentou-se como ferramenta com grande potencial de contribuição, no sentido de permitir conhecer os resultados possíveis das diferentes combinações tecnológicas disponíveis. O modelo ainda permite ser utilizado como ferramenta de estudo e análise para a cadeia produtiva, contribuindo na orientação aos cientistas, auxiliando no direcionamento de seus esforços no desenvolvimento de futuras pesquisasConduct an economic analysis of agricultural production is not trivial, either by its enormous heterogeneity between each production unit, or because it uses many natural resources, some of which are difficult to measure. There are several methods available for calculating the cost of production, which is the key indicator for assessing the feasibility of a project. The challenge is to allow the projection of activity in the productive horizon in the most real and dynamic form as possible. The computer simulation is currently one of the most powerful analysis tools available for planning, design and control of complex systems and is being increasingly used and disseminated. Simulate includes the development of a method of testing by building models of a real system, that seeks to describe behaviors, build theories or hypotheses through noted and predicted future behaviors. The use of simulation models that incorporate uncertainty and probability in animal production can be both an alternative technique - assisting in decision-making, management and livestock planning; as scientific - allowing the evaluation of the research results of effects and identification of limiting that may encourage the development of future research. The model of hybrid simulation - based on discrete event simulation and on agent-based, proposed here - aimed to identify factors husbandry and management criteria that most affect the production of meat sheep. The model of hybrid computer simulation have dynamic and probabilistic characteristics, with events scheduled in time (breeding season, pregnancy, parturition, weaning, fattening, slaughter, etc.) and enough complexity that its agents be adversely affected both in time and in response to the occurrence or not of variables linked to them. The results of the experiments and the scenarios studied showed that among the zootechnical indexes of the sheep, the occurrence of abortion generates a greater impact on the slaughter rate and financially in the net operating margin. However, analyzing the variables for both sheep and lambs, neonatal mortality, up to the lambs\' five days of life, proved to be the fundamental point for the profitability of the activity. The stabilization of the herd was more affected by the presence of adult sheep in the herd, which culminated increasing the number of lambs per sheep. The results of the analysis of the 30-year cash flows, at a minimum attractiveness rate of 6.17% per year, showed that starting the activity with a very small number of sheep was the least interesting scenario, with a negative internal rate of return for the analysis period. The study of the cash flow allowed to assign to 200 sheep as the most interesting initial herd size (IRR = 3.30% per year). Thus, the use of hybrid simulators, based on discrete event simulation and agent-based for studies in national livestock, is presented as a tool with great potential to contribute, to allow knowing the possible outcomes of different combinations of available technology. The model also allows to be used as a study tool and assessment of different technological combinations for the production chain, contributing to the guidance of scientists, assisting their efforts in the development of future research

Previous issue date: 2012-10-23From its beginning in 2007, the U. S. Subprime Crisis can be considered the largest one occurred in the century so far, mainly for its extension, since shortly after the release of the first facts, many countries have shown signs of having been contaminated by its effects. Moreover, other nations such as Brazil sought to say that would not be affected, given the solid basis that its economy has shown. Brazil really showed signs of improvement in the economy a few years before the crisis: Gross Domestic Product - GDP was growing, inflation was under control and the employment level improved. By contrast, the United States had problems in the stock market in 2000 and had suffered the biggest terrorist attack in its history in 2001, which led to an outbreak of wars in other countries. This situation generated a bad effect on the U.S. economy, since the level of employment did not improve and prices rose, mainly on real estate assets. Many signs of problems in the U.S. economy were released, mainly the huge appreciation in real estate prices. In early 2007, companies in the mortgage industry began to have financial problems, however it was in August, when the French bank BNP Paribas announced the suspension of investment funds with roles in applications related to the mortgage that the world turned its look at the U.S. housing market. Throughout the following months, as the situation did not improve, many companies divulged disclosed financial problems and went bankrupt, such as Lehman Brothers, a hundred years old banking institution., which announced its bankruptcy in September 2008. Such a troubled scenario on the U.S. inspired this research to evaluate the effects of the crisis on the stock price of companies in the American an Brazilian Building sector. The industry was chosen due to its importance in generating employment, recent expansion of the real estate sector in Brazil and its link to the U.S. mortgage contracts. Five U.S. construction companies and also 5 Brazilian companies with publicly exchanged stocks were chosen. We selected the event study technique to accomplish the work. We found that the two facts related to Banco BNP Paribas and the bankruptcy of Lehman Brothers generated abnormal returns in stock prices of those 10 companies in the days preceding and following the disclosure of facts,, which contradicts the postulated assumption of the efficient market theory: that given that the market rationality and prices are adjusted to the information disclosed, the expected return is normal,
Iniciada nos Estados Unidos em 2007, a chamada Crise Subprime pode ser considerada a maior ocorrida no século até o momento, principalmente pela sua extensão, já que, pouco tempo depois da divulgação dos primeiros fatos, muitos países deram sinais de terem sido contaminados por seus efeitos. Por outro lado, outras nações como o Brasil procuravam afirmar que não seriam afetados, dados os sólidos fundamentos que sua economia apresentava. O Brasil realmente o apresentava sinais de melhoria na economia alguns anos antes, o Produto Interno Bruto PIB crescia, a inflação estava sob controle e o nível de emprego melhorava. Em contrapartida, os Estados Unidos, vinha de problemas no mercado acionário em 2000 e havia sofrido o maior ataque terrorista de sua história em 2001, o qual motivou o início de guerras em outros países. Tal situação produziu efeito ruim na economia norte-americana, uma vez que o nível de emprego não melhorava e os preços subiam, principalmente os dos imóveis. Muitos sinais dos problemas na economia norte-americana eram divulgados, principalmente quanto à valorização gigantesca nos preços dos imóveis. E, no início de 2007, empresas do setor de hipoteca começaram a ter problemas financeiros; no entanto foi em agosto, quando o Banco francês PNB Paribas divulgou a suspensão de fundos de investimentos com aplicações em papéis vinculados à hipoteca, que o mundo voltou seu olhar para o mercado imobiliário norte-americano. No decorrrer dos meses seguintes, a situação não melhorava, pelo contrário, mais empresas divulgavam problemas financeiros e até faliam, como foi o caso do Lehman Brothers, uma instituição bancária centenária, que anunciou falência em setembro de 2008. O cenário tão conturbado nos EUA motivou a realização da pesquisa para avaliar os efeitos da crise no preço das ações de empresas do setor de construção civil norteamericano e brasileiro. O setor de construção civil foi escolhido em função sua importância na geração de emprego, a recente expansão do setor imobiliário no Brasil e seu vínculo com os contratos de hipoteca nos EUA. Foram selecionadas 5 construtoras norte-americanas e 5 brasileiras com ações negociadas em bolsas de valores. Para a realização da pesquisa, foi selecionada a técnica estudo de eventos, e o resultado apurado foi que os dois fatos relacionados ao Banco BNP Paribas e a falência do Lehman Brothers geraram retornos anormais nos preços das ações das 10 empresas, nos dias anteriores e posteriores à divulgação dos fatos. Tal resultado contraria o postulado da teoria de mercado eficiente, visto que o retorno esperado é o normal, dado que o mercado é racional e os preços são ajustados às informações divulgadas

Full textAbstract:
The objective of this project is to develop an operational scheduling model for Sasol Mining’s coal handling facility, Sasol Coal Supply (referred to as SCS), to optimise daily operations. In this document, the specific scheduling problem at SCS is presented and solved using Mixed Integer Non-Linear Programming (MINLP) continuous time representation techniques. The most recent MINLP scheduling techniques are presented and applied to an example problem. The assumption is made that the results from the example problem will display trends which will apply to the SCS scheduling problem as well. Based on this assumption, the unit-specific event based continuous time formulation is chosen to apply to the SCS scheduling problem. The detail mathematical formulation of the SCS scheduling problem, based on the chosen technique, is discussed and the necessary changes presented to customise the formulation for the SCS situation. The results presented show that the first phase model does not solve within 72 hours. A solution time of more than three days is not acceptable for an operational scheduling model in a dynamic system like SCS. Various improvement approaches are applied during the second phase of the model development. Special Ordered Sets of Type 1 (SOS1) variables are successfully applied in the model to reduce the amount of binary variables. The time and duration constraints are restructured to simplify the structure of the model. A specific linearization and solution technique is applied to the non-linear equations to ensure reduced model solution times and reliable results. The improved model for one period solves to optimality within two minutes. This dramatic improvement ensures that the model will be used operationally at SCS to optimise daily operations. The scheduling model is currently being implemented at SCS. Examples of the input variables and output results are presented. It is concluded that the unit-specific event based MINLP continuous time formulation method, as presented in the literature, is not robust enough to be applied to an operational industrial-sized scheduling problem such as the SCS problem. Customised modifications to the formulation are necessary to ensure that the model solves in a time acceptable for operational use. However, it is proved that Mixed Integer Non-linear Programming (MINLP) can successfully be applied to optimise the scheduling of an industrial-sized plant such as SCS. Although more research is required to derive robust formulation techniques, the principle of using mathematical methods to optimise operational scheduling in industry can dramatically impact the way plants are operated. The optimisation of daily schedules at SCS by applying the MINLP continuous time scheduling technique, has made a significant contribution to the coal handling industry. Finally, it can be concluded that the SCS scheduling problem was successfully modelled and the operational scheduling model will add significant value to the Sasol Group.Dissertation (MEng (Industrial Engineering))--University of Pretoria, 2006.

Since sustainable materials management and the concept of sound material-cycle society are increasingly crucial, Taiwan society continues to promote resource recycling in recent years, and recycling industries keep working on technological innovation in the waste recycling. This study focuses on the effects of announcement of changes in regulation reform and technological innovation on stock returns of recycling industry companies. The empirical results indicate when there are regulation reforms regarding recycling industry, investors' perception on the reform announcement is significantly reflected in company's abnormal stock returns. However, the announcement of technological innovation does not affect the stock returns of underlying company and its competitors.

Since food is the most important to people, food safety always takes the priority. In recent years, the major food safety issues often brought strong concerns. This study uses the Event Study to investigate whether occurrences of food safety issues would cause abnormal returns for food related companies. Main study events are the plasticizer event in 2011, the tainted starch event in 2013 and the tainted oil event including pigwash oil, feed oil and problematic butter oil in 2014. Discussion of their impacts on stock prices of related companies is made. The results of study shows that negative abnormal returns at significant level for food related stocks in Taiwan exist after occurrences of the plasticizer event and the tainted oil event. On the other hand, for the tainted starch event, significant negative abnormal returns only appear in the first three days. In terms of the degree of influence, the greatest impact to the food related companies was from the tainted oil event resulting in both the most negative abnormal returns and cumulative average abnormal returns.

Why did industrial chemicals adulterate food additives? Based on this question, this study takes the plasticizer event in Taiwan in 2011 as an example. In the past, the related researches on this food adulteration cases were mainly based on toxicology, cross-country law comparison, and risk society research. Different from the approaches above, this research is based on the social construction of technology (SCOT) and applied it as the main conceptual framework. Thus, this study can highlight the role of artifacts, relevant social groups, and industries in the food safety crisis in Taiwan. Through the perspective of SCOT, this paper is divided into three parts. The first part focuses on the soft drink industry in Taiwan and the role of clouding agents. The natural juices, which standards were based on European and American juice products, set off a boom in Taiwan in the late 1970s. Although the juice with higher fruit nectar performed poorly in soft drink market, the thick taste and turbid appearance had become the standard for manufacturers to produce juice. Hence, this historical background increased the chance of using clouding agents in fruit-flavored drinks. In the second part, the manufacturing process of plasticized clouding agent illustrates the state of industrial local knowledge. Analyzing with the emulsion flavor technology frame, we have been able to label the plasticized clouding agents as a conventional invention under the existing technology frame, as well as a toxic invention that causes harm to the human body. Since most of food flavors in Taiwan have depended on imports, relevant social groups are small and weak. Therefore, compared with the United States and Japan, there are only a few manufacturers in Taiwan have their unique flavor formula, and most of them keep the formula underground. The third part, we explore the way flavor manufacturers got their access to plasticizers, as well as the boundaries they had crossed. Manufacturers of plasticized clouding agents relied on the assistance of wholesalers of chemicals and also relied on their own technique to produce plasticized clouding agents. The existing thought style in the flavoring industry, which includes flavor imaginary, allowed manufacturers to overlook the potential risk of the human hazard of the plasticized clouding agent.
