Dissertations / Theses on the topic 'Market surveys'

This dissertation explores methods to improve the quality of data about sensitive labor market topics, such as undeclared work and receipt of basic income support in Germany, using surveys of the general population. Due to the sensitive nature of both topics, respondents may choose to misreport and adjust their answers in accordance with social norms. Over the past decades, special strategies—particularly targeted to reduce misreporting on sensitive topics—have been developed. One such class of data collection strategies are so-called ‘dejeopardizing’ techniques, out of which the randomized response technique (RRT) and the item count technique (ICT) are the most popular and best investigated ones. The goal is to elicit more honest answers from respondents by increasing the anonymity of the question-and-answer process. These techniques provide prevalence estimates as well as estimates of regression coefficients, regressing dependent variables generated by means of RRT or ICT on a set of covariates of interest. However, these dejeopardizing techniques have not been applied to collect data on undeclared work or receipt of welfare benefits in German surveys. This dissertation aims at closing this gap using an experimental design that allows us to compare the performance of these dejeopardizing techniques to direct questioning. In 2010 we conducted two telephone surveys on undeclared work and welfare benefit receipt. We experimentally tested whether the RRT, the ICT, or the newly developed item sum technique (IST) reduce bias due to social desirability compared to direct questioning (under the ‘more-is-better’ assumption and using validation data in one study). Our results suggest that neither the RRT nor the ICT provide unambiguous results with respect to improving the accuracy of reports of the socially undesirable behavior, while the IST results were more promising. This dissertation provides insights into a variety of practical and theoretical factors contributing to a successful implementation of the RRT, the ICT and the IST in labor market surveys.
Die vorliegende Dissertation geht der Frage nach, wie das Ausmaß von Schwarzarbeit und Arbeitslosengeld-II-Bezug in Deutschland im Rahmen von Befragungen der allgemeinen Bevölkerung möglichst valide geschätzt werden kann. Aufgrund des heiklen Charakters beider Themen ist davon auszugehen, dass Selbstauskünfte häufig nicht der Wahrheit entsprechen und stattdessen in vielen Fällen sozial erwünschte Antworten gegeben werden und das Verhalten systematisch unterberichtet wird. Um diesen Antwortverzerrungen entgegen zu wirken, wurden in den letzten Jahrzehnten in der empirischen Sozialforschung alternative Befragungstechniken entwickelt. So basieren beispielsweise die Randomized Response Technique (RRT) und die Item Count Technik (ICT) auf dem Prinzip der verschlüsselten Antworten und sollen durch eine Erhöhung der Anonymität in der Interviewsituation sozial erwünschtes Antwortverhalten reduzieren. Der Vorteil dieser Erhebungsverfahren liegt darin, dass zum einen weniger Annahmen hinsichtlich der Schätzungen getroffen werden und zum anderen mittels statistischer Auswertungen ziel gerichtet multivariate Zusammenhänge zwischen einer mit ICT oder RRT generierten abhängigen Variablen und Kovariaten auf individueller Ebene untersucht werden können. Bislang wurden diese Techniken allerdings noch nicht zur Erhebung von Schwarzarbeit oder des Bezugs von Arbeitslosengeld-II in Deutschland eingesetzt. Die Dissertation schließt diese Lücke und beschäftigt sich mit einem experimentellen Vergleich – sowie einer Weiterentwicklung – von Erhebungstechniken speziell für heikle Fragen mit einer direkten Befragung im Kontext von Arbeitsmarktsurveys. Mittels Fragen zum Thema Schwarzarbeit und zum Arbeitslosengeld-IIBezug, wird im Rahmen zweier Bevölkerungsbefragungen aus dem Jahre 2010 empirisch untersucht ob die RRT, die ICT bzw. die eigens entwickelte Item Sum Technik (IST) den Befragten tatsächlich ein höheres Ausmaß sozial unerwünschter Antworten entlocken als die direkte Befragung (unter der bekannten ‘more-is-better’ Annahme sowie mittels einer Validierungsstudie). Die Befunde zeigen, dass die häufig angenommene Wirkung der RRT oder der ICT auf die Bereitschaft der Befragten, sozial unerwünschtes Verhalten zu berichten, nicht eindeutig ausfällt. Die Ergebnisse der IST fallen hingegen positiver aus. Die vorliegende Dissertation liefert somit Hinweise hinsichtlich verschiedener praktischer als auch theoretischer Faktoren, die zu einer erfolgreichen Implementation der RRT, der ICT und der IST in Arbeitsmarktsurveys beitragen können.

A key question that marketers and salespeople face is based on the dilemma of which customer to pursue and which not. This choice has far reaching effects in both company success. Investigating a client’s seriousness to make a purchase at the time of an enquiry is key. This will assist the firm in determining which future clients offer the firm the most potential value in sales turnover and company profits. By taking the client’s background and history into consideration the marketer has the opportunity to determine which clients have or have not previously committed to the firm and which did not. By profiling the customer, providing a yardstick against which one can measure probability of a purchase can be developed. New or prospective customer against those attributes of customers can then be benchmarked against the attributes that attest to whether interest and intention to purchase can be converted into a sale. Identifying these customers who will be most likely to make a purchase is a very important area of study for any business that focuses on the marketing and sales of products or services. Having an accurate profile of potential customers, of who will buy and who will not, will play a key role in the success of any organization. The focus of this study will be on investigating the profile of a potential customer/company as a benchmark for sales lead qualification. The profile will also be a precursor to determining the lifetime value of the prospective customer. Profiling of high sales potential customers is a management issue. It directly influences the number of hours key personnel in the sales department spend on key tasks, which can alternatively be spent more productively on other projects.

ENGLISH ABSTRACT: In order to evaluate the extent to which South Africa achieve the objectives of poverty and inequality reduction as well as job creation, up-to-date and reliable data are required. Since the transition, various survey data have been commonly used for these analyses, namely Census, Community Survey (CS) 2007, Income and Expenditure Survey (IES), October Household Survey (OHS), Labour Force Survey (LFS), Quarterly Labour Force Survey (QLFS), General Household Survey (GHS), Project for Statistics on Living Standards and Development (PSLSD), National Income Dynamics Study (NIDS) and All Media Products Survey (AMPS). However, these datasets are not fully comparable, due to differences in the sampling design, sample size, questionnaire structure, methodology to derive labour market status, as well as the way the income and expenditure information was collected. Hence, this dissertation begins by analysing these issues in each survey in Chapter 2. With regard to the income and expenditure information, it was collected differently in the surveys: the recall method was used in all surveys except IES 2005/2006, the only survey that adopted the diary method; respondents were asked to report the actual amount in some surveys but only asked to declare the relevant interval in others; for the former approach, respondents could either declare the single estimate amount or amounts for sub-categories that were then aggregated; for interval data, various methods can be used to determine the amount in each interval. Thus, Chapter 3 begins by discussing the merits and drawbacks of these approaches, as well as how they would affect the reliability and comparability of income and expenditure variables across the surveys. In some surveys (e.g., the two censuses and CS 2007), quite high proportions of households incorrectly reported zero income or expenditure or did not specify their income or expenditure. Poverty and inequality estimates could be influenced by either including or excluding these households from the analyses. Hence, various approaches to deal with these households are examined in Chapter 3. As the surveys typically under-captured income or expenditure when compared with the national accounts income, the validity of the resultant poverty and inequality estimates might be affected. Hence, arguments for and against adjusting the survey means in line with the national accounts mean (e.g. by shifting the survey distribution rightwards) are discussed. As the survey data are, strictly speaking, crosssectional and not designed for time-series labour market, poverty and inequality analyses, it is sometimes argued that the data should be re-weighted to be consistent with demographic and geographic numbers presented by the Actuarial Society of South Africa (ASSA) and Census data. This cross entropy re-weighting approach is discussed in Chapter 3. Finally, the chapter examines the labour market status derivation methodology in all OHSs, LFSs and QLFSs in greater detail, and investigates how the changes across the surveys could possibly affect the comparability of labour market estimates throughout the years. The dissertation then examines the labour market trends since the transition by using the OHS, LFS and QLFS data, and it is found that both the labour force and employment numbers increased in general since the transition, but the latter increase was not rapid enough to absorb the expanding labour force. In addition, the number of narrow unemployed doubled between 1994 and 2009, and the narrow unemployment rate showed an upward trend and peaked at just above 30% in 2003. It decreased between 2004 and 2007, before rising again in 2008- 2009 due to the impact of global recession. Application of the cross entropy approach does not substantially affect labour market trends, suggesting that the trends (including the abrupt increase in labour market estimates during the changeover from OHS to LFS) were either real or took place due to the improvement of the questionnaire to capture the labour market status of the respondents better. Furthermore, the application of the LFS 2000b-LFS 2007b methodology on the earlier surveys reduced the extent of the abrupt increase of the number of broad unemployed and broad unemployment rates during the changeover between OHS and LFS. Finally, the use of the QLFS methodology (which required minor revisions) on the LFSs greatly reduced the extent of the abrupt decrease of unemployment aggregates between LFS 2007b and QLFS 2008Q1, thereby improving the comparability of these aggregates across the surveys. In Chapter 5 poverty and inequality concepts are reviewed, followed by a detailed explanation of the sequential regression multiple imputation (SRMI) technique to deal with households with zero or missing income or expenditure, as well as the derivation of real income, expenditure and consumption variables in each survey. Poverty and inequality trends since the transition are examined in Chapter 6. With regard to poverty, with the exception of AMPS, the poverty trends were very similar across the surveys, that is, poverty increased since the transition, before a downward trend took place since 2000. As far as inequality is concerned, both the levels and trends in the Gini coefficients differed a lot amongst the surveys, as the estimates were very stable in the AMPSs, showed an upward trend in surveys like IESs and GHSs, but first increased until 2000 before a downward trend took place in others (e.g., the two censuses and CS 2007). The levels of inequality also differed when comparing the surveys. The abovementioned poverty and inequality estimates and trends could in part be affected by the various issues discussed in Chapter 3, thus there is a need for careful analysis. The impact of the number and width of intervals in which income or expenditure data are recorded on poverty and inequality estimates and trends are dealt with in greater detail in Chapter 6 by applying various intervals on the three IESs and NIDS 2008. It is found that the number and width of intervals only had some impact on these estimates and trends in some surveys. The effect of adjusting the survey means in line with the national accounts mean is also investigated. Finally, the application of the cross entropy re-weighting technique did not have any significant impact on the poverty and inequality estimates and trends.
AFRIKAANSE OPSOMMING: Data wat op datum en betroubaar is word vereis om te kan evalueer in watter mate Suid- Afrika sy doelwitte rakende die vermindering van armoede en ongelykheid en die skepping van werkgeleenthede bereik. Sedert die politieke oorgang word verskeie opnamedatastelle gewoonlik vir sulke ontledings gebruik, byvoorbeeld Sensusse, die Gemeenskapsopname van 2007, Inkomste- en Bestedingsopnames, Oktober-huishoudingsopnames, Arbeidsmagopnames, Kwartaallikse Arbeidsmagopnames, Algemene-Huishoudingsopnames, die Nasionale-Inkomste-Dinamika-Studie en die Alle-Media-en-Produkte-opnames. Weens verskille in steekproef-ontwerp, struktuur van die vraelyste, metodologie om arbeidsmarkstatus te klassifiseer, asook maniere waarop inligting oor inkomste en besteding ingewin is, is hierdie datastelle egter nie ten volle vergelykbaar nie, Gevolglik begin hierdie proefskrif in Hoofstuk 2 om elk van hierdie kwessies in elke opname te ontleed. Inkomste- en bestedingsinligting is in die opnames verskillend ingewin: In die meeste opnames is respondente gevra om aan te dui hoeveel hulle in die verlede bestee of verdien het, maar in die Inkomste- en Bestedingsopname van 2005/2006 is die dagboekmetode gebruik; respondente is in party opnames gevra om die presiese bedrag te vermeld, terwyl hulle in ander opnames die betrokke inkomste- of bestedingsinterval moes aandui; vir eersgenoemde is hulle gevra om òf die enkelbedrag te verklaar, òf hulle moes ‘n aantal sub-komponente onderskei; vir intervaldata kan verskillende metodes gebruik word om skattings van die inkomste in elke interval te maak. Dus begin Hoofstuk 3 met ‘n oorsig van die voor- en nadele van die verskillende benaderings en ‘n bespreking van hoe dit die betroubaarheid en vergelykbaarheid van inkomste- en bestedingsveranderlikes oor die opnames beïnvloed. In party opnames (bv. die twee sensusse en die Gemeenskapsopname van 2007) dui heelwat huishoudings verkeerdelik aan dat hulle geen inkomste verdien of uitgawes aangaan nie, of hulle spesifiseer nie hoeveel hulle verdien of bestee nie. Ramings van armoede en ongelykheid kan geraak word deur sulke respondent in te sluit of deur hulle uit te laat in die ontledings. Gevolglik word verskeie benaderings in Hoofstuk 3 bespreek om hiermee om te gaan. Omdat opnames vergeleke met die nasionale rekeninge tipies inkomste of besteding onderskat, mag dit die geldigheid van daaruitvoortspruitende armoede- en ongelykheidsramings raak. Gevolglik word argumente vir en teen die aanpsssing van die opname-data om dit in ooreenstemming te bring met die nasionale rekeninge (d.w.s. deur die verdeling na regs te verskuif) bespreek. Ten slotte, omdat die opnamedata streng gesproke kruissnitdata is en nie ontwerp is vir tydreekse van die arbeidsmag, armoede en ongelykheid nie, word soms aangevoer dat die gewigte van die data herweeg moet word om in ooreenstemming te wees met demografiese en geografiese data soos verkry van die Aktuariële Vereniging van Suid-Afrika en sensusdata. Hierdie kruisentropie herwegingsmetode word in Hoofstuk 3 bespreek. Ten slotte ondersoek die laaste hoofstuk die metodologie vir die bepaling van arbeidsmarkstatus in all die OHS, LFS en QLFS opnames in groter besonderhede, en ook hoe die veranderings oor die verskillende opname-reekse heen dalk die vergelykbaarheid van arbeidsmarkramings deur die jare kan beïnvloed. Die proefskrif ontleed daarna arbeidsmarktendense sedert die politieke oorgang met gebruik van die Oktober-huishoudingsoponames, Arbeidsmagopnames en Kwartaallikse Arbeidsmagopnames. Beide die arbeidsmag en indiensneming het sedert die transisie toegeneem, maar die toename in indiensneming was onvoldoende om die uitbreiding van die arbeidsmag te absorbeer. Verder het die getal eng-gedefinieerde werkloses tussen 1994 en 2009 verdubbel, en die eng werkloosheidskoers het ‘n toename getoon en in 2003 ‘n toppunt van 30% bereik. Dit het daarna tussen 2004 en 2007 gedaal voordat dit weer in 2008-2009 gestyg het weens die wêreldreseessie. Die toepassing van die kruisentropie-benadering het arbeidsmarktendense nie noemenswaardig beïnvloed nie, wat daarop dui dat hierdie tendense (insluitende die skielike toename in arbeidsmagramings in die oorgang van die Oktoberhuishoudingsopname- data na die Arbeidsmarkopname-data) werklik was, of anders plaasgevind het weens veranderings in die opnamevraelyste om respondente se arbeidsmarkstatus beter te probeer bepaal. Verder het die toepassing van die LFS2000b tot LFS 2007B metodologie op die vroeëre opnames die abrupte verlaging in die oorgang tussen die OHS en LFS in die getal breed-gedefineerde werkloses en breë werkloosheidkoerse verminder. Ten slotte het die gebruik van die QLFS-metodologie op die LFS (wat kleiner hersienings benodig het) die abrupte verlaging tussen LFS2007b en QLFS2008Q1 aansienlik verminder, en dus die vergelykbaarheid van hierdie groothede oor die opnames heen verbeter. In Hoofstuk 5 word eers ‘n oorsig van armoede- en ongelykheidsbegrippe gegee, waarma die sekwensiële-regressie-veelvoudige-imputasie-tegniek in besonderhede bespreek word. Hierdie tegniek word veral gebruik vir gevalle waar huishoudings aandui dat hulle inkomste of besteding nul is, of waar hulle nie antwoord nie. Daar is ook ‘n bespreking van die bepaling van reële inkomste, besteding of verbruiksveranderlikes in elke opname. Armoedeen ongeleykheidstendense word in Hoofstul 6 bespreek. Rakende armoede is daar, met uitsondering van die Alle-Media-en-Produkte-opname, eenstemmigheid dat dit sedert die politieke oorgang eers gestyg het voor dit sedert 2000 begin daal het. Sover dit ongelykheid aanbetref verskil neigings in die Gini-koëffissiënt baie tussen die opnames, want die ramings is stabiel oor die periode vir die Alle-Media-en-Produkte-opname, styg vir die Inkomste- en Bestedingsopname en die Algemene-Huishoudingsopnames, en styg tot 2000 voordat dit afneem in ander opnames (bv. die twee sensusse en die Gemeenskapsopname van 2007). Vlakke van ongelykheid verskil ook tussen die opnames. Deels kan die genoemde tendense in armoede- en ongelykheid dalk toegeskryf word aan die kwessies wat in Hoofstuk 3 bespreek is. Die effek van die getal en wydte van die intervalle waarin inkomste- en bestedingsdata ingewin word op ramings van armoede en ongelykheid word in meer besonderheid in Hoofstuk 6 bespreek. Deur die toepassing van verskillende intervalle op data van die drie Inkomste- en Bestedingsopnames en die Nasionale-Inkomste-Dinamika-studie word bevind dat die getal en wydte van intervalle ‘n beperkte effek op hierdie ramings en tendense het. Verder word gekyk na die effek van die aanpssing van die opname-data om dit in ooreenstemming met die nasionale rekeninge te bring. Ten slotte word getoon dat die gebruik van die kruisentropie-metode nie enige beduidende uitwerking op armoede- en ongeleykheidsramings en -tendense het nie.

This thesis presents the results from a survey of transit agencies on web-based feedback tools and their role in enabling communication between agencies and riders. Motivation for the survey stems from the growing importance of web-based feedback tools in improving transit services. Web-based feedback can improve transit agencies' knowledge of issues relating to their systems while enhancing the transit riding experience. As the availability of Internet and smartphones increases among transit users, the tools available to gather feedback have grown in response. Web- and smartphone-based tools are instrumental in collecting a wide range of feedback, including commendations and complaints, maintenance issues, transit services, safety and security, long-term planning and other transit operations related issues. At the same time, transit agencies must determine how to best respond and manage the growing presence of information on the web relating to their agencies performance. Through a web-based survey administered to 130 transit agencies in the United States and Canada, information was gathered on the current and planned use of web-based tools by transit agencies. The overall survey results show that most transit agencies focus on sorting and responding to unsolicited feedback being collected primarily through social media, email, and online forms. Additionally, transit agencies see the benefits of web-based customer feedback, noting that the key to managing their systems into the future will involve developing agency-wide digital feedback plans that allow automation and integration across all feedback channels. Finally, transit agencies also noted that the primary downside to web-based feedback involved a lack of staff resources to support their systems. This thesis provides further analysis focusing on three questions regarding the survey results: - How can agency size, based on unlinked trips, influence the survey responses collected from agencies regarding their use of web-based feedback tools? - What variables from the survey can influence a transit agencies ability to provide web-based feedback tools to their riders? - What factors might contribute to differences in transit agencies rider access estimates to Internet and smartphones? While the results show that larger agencies are able to offer more web-based feedback tools to their riders, there were problems with transit agencies incorrectly estimating their riders’ access to Internet and smartphones. This could cause issues regarding agencies ability to understand which web-based tools they should implement to engage their riders. This thesis details one portion of an overall project, which will provide framework for agencies to assess their needs and resources to determine how to create their own effective customer feedback systems in relation to what web-based feedback tools will most benefit themselves and their riders.

To date, the collection of comprehensive household travel data has been a challenge for most metropolitan planning organizations (MPOs) and state departments of transportation (DOTs) due mainly to high costs. Urban population growth, the expansion of metropolitan regions, and the general unwillingness of the public to complete surveys conflict with limited public funds. The purpose of this research is to leverage targeted marketing data, sometimes referred to as consumer data or just simply marketing data, for travel demand modeling applications. This research reveals a first step in exploring the use of targeted marketing data for representing population characteristics of a region. Four studies were completed: an aggregate validation, a household-level validation for hard-to-reach population groups, an airport passenger model, and a residential location choice model. The two validation studies of this work suggest that targeted marketing data are similar to U.S. Census data at small geographic levels for basic demographic and socioeconomic information. The studies also suggest that the existing coverage errors are at least similar, if not lower than, the levels of those in household travel surveys used today to build travel demand models. The two application studies of this work highlight the benefits of the targeted marketing data over traditional household travel surveys and U.S. Census data particularly well, including the additional behavioral information available at the household-level and the very large sample sizes. These results suggest that the combination of targeted marketing data with other third-party and non-traditional data could be particularly powerful. It offers tremendous opportunities to enhance, or even transform, existing travel demand modeling systems and data collection practices. Inexpensive, up-to-date, and detailed data would allow researchers and decision-makers alike to better understand travel behavior and to be more equipped to make important transportation-related decisions that affect our lives each day.

The research investigated acquisition and disposition behavior of purchasers, purchasers/consignors, and consignors of secondhand clothing in consignment stores. A questionnaire was administered to 168 women and two men in three Roanoke, Virginia stores. It was hypothesized that (1) long-time purchasers (three to five years) patronized other secondhand sellers more than short-time purchasers (two years or less); and that purchasers (2) acquired (a) primarily to save money and (b) secondarily to have well-made clothing, (3) bought two to four times a month, and (4) were satisfied with stores' merchandise and services. Hypotheses 2a and 4 were supported but 1, 2b, and 3 were not. A hypothesis that consignors consigned to obtain a return on clothing investments and get rid of unwanted items was supported. Friends were important information sources about stores. Chi-square analysis indicated that respondent groups were similar demographically, in the types of clothing they purchased and/or consigned, and in the uses of clothing purchased. Host respondents were Caucasian, 30-49 years old, and often had baccalaureates or other post-high school education. Twenty-seven percent of the respondents had total household incomes of $40,000 or more. The most frequently purchased and consigned garments were shirts or blouses. Purchasers and purchasers/consignors used purchased clothing primarily for social occasions. Purchasers and consignors differed on the number of years they had been patronizing stores and on their purchasing and consigning frequencies. Also, more purchasers than purchasers/consignors patronized flea markets and garage sales.

The purpose of this project is to gain a better understanding of gender segmentation strategy possibilities in the Kingdom of Saudi Arabia. The findings from this survey graphically illustrate and statistically demonstrate some critically important information about the consumer demographics, needs, and behaviors of the targeted female Saudi shopper.

The primary objective of this study is to determine the viability of opening a speciality top end, Ethnic cosmetic and toiletry retailer in the Greenacres Mall of Port Elizabeth, in order to meet the cosmetic and toiletry needs of Ethnic consumers, having moved from rural places of work and dwelling, to urban areas of work and dwelling. In order to achieve the above mentioned primary objective, the following secondary objectives will be pursued: • To investigate the current and forecast Ethnic cosmetic and toiletry trends in the United States of America, in order to serve as a benchmark in the development of a top end, speciality Ethnic cosmetic and toiletry retail store model, for the Greenacres Shopping Mall in Port Elizabeth, South Africa; • to identify whether a top end, speciality Ethnic cosmetic and toiletry store model for the Greenacres Shopping Mall in Port Elizabeth, South Africa, would be a viable business venture; • to investigate current and forecast Ethnic cosmetic and toiletry trends in South Africa, in order to reveal the shortfalls of retailers targeting this market segment; and • to identify the best business model for an organisation or individual wanting to grow their business through targeting the Ethnic cosmetic and toiletry consumer

The primary objective of this thesis is to study the role of surveys as power factor with a particular focus on studies of Internet users. The conditions and practices of the private research field are related to the academic discourse on the essence of science as well as to media's role in society. The methodological basis of the quantitative studies and their practices are examined in relation to a range of competing theories on the nature of science and its role in society. Earlier contributions to the criticism of quantitative surveys are also discussed. The methodological problems are further highlighted by concrete examples based on own analyses of various data collections. One empirical part of the thesis consists of analyses of survey studies as reported in the press coverage of the Internet in 1997, 1999 and 2000. The goal of the analyses is to show that surveys are an important mechanism for creating truth effects. The methodological tools are part of the struggle for mastery of the discourse –thereby confirming or changing existing power relations – in part through the dissemination of selected results in the media. Through a perusal of the newspaper articles with regard to the context in which the keywords "Internet" and "survey" appear and what the specific actor says, to whom, with which intention, an overall discourse appears, which reveals that the leading commercial actors endeavour to promote the development of the Internet in accordance with their aspirations. The published results are also related to other, more complex analyses of data collections from the same period. In another empirical part of the thesis findings from some fifty interviews with various experts are presented. The aim is to evaluate the methodological sources of error associated with sampling, the carrying out of studies, the analysis of results and other factors that have to do with the value of the surveys as basic facts, as well as the survey buyers’ awareness of the nature of the errors and their relevance for the results. The quantitative surveys appear as an uncontrolled and uncertain source of knowledge. The survey industry is profit-oriented and characterised by competition whereby methodological issues often land up in the background. The final discussion addresses a set of mechanisms by which the interested parties from the media industry use the ratings in the internal competition or in various administrative documents. They achieve this by establishing a "common currency" on the basis of such studies, which is valid in relation to other interested parties, such as media owners and advertisers. Different strategies developed by the survey industry in order to lend more market value to their products are also discussed. The methodological problems, the lack of openness to external scrutiny and the dependence on the economic field signify that the praxis of the survey field essentially deviates from the basic concepts of science. Surveys take therefore undue  advantage of scientific legitimacy.

The strategic importance of customer retention and the costs associated with customer switching behaviour have resulted in researchers devoting considerable attention to investigating the switching and/or staying behaviour of customers. However, relatively little attention has been devoted to investigating (1) the important deterrents to discontinuing the relationship in a single model in the business-to-business (B-to-B) service sector, and (2) the mediating factors under the condition of dissatisfaction in the B-to-B services sector. The fastest growth in services marketing today is in business markets, making this an important area of study with significance for marketers, particularly in terms of the development of customer retention. A two-stage research design, with qualitative and quantitative phases, was employed in the current research using a single key informant approach. The qualitative study utilised an indepth interview technique in which key informants representing 21 businesses provided interviews. The quantitative study employed a cross-sectional email URL embedded Web survey of key informants, which resulted in a final sample size of 376 responses. The simultaneous nature of the multiple relationships between key constructs was analysed using structural equation modelling. The research demonstrated that distributive justice, procedural justice, interactional justice, satisfaction with complaint—handling, benefit-loss costs, economic-loss costs, learning costs, sunk costs, interpersonal relationships, dependence and calculative commitment are the direct and indirect factors that influence the likelihood of dissatisfied customers remaining in a relationship. A key finding is the mediating role of both dependence and calculative commitment on the relationship between specific firmlevel investments and repurchase intentions. This thesis makes four contributions. Firstly, it uses a business services context, which is an under—researched area for this research problem. Secondly, it connects determinant factors to an outcome variable in explaining the tendency among B—to-B services customers, who have complained and considered switching, to remain involved in a relationship that is dissatisfying overall. Thirdly, it examines the effects of antecedents on calculative commitment that have previously not been examined, thus making a conceptual and empirical contribution. Finally, it offers managerial implications for the offending service firms as well as for those service firms that are attempting to attract dissatisfied prospective switchers of the offending firm.

A reliable sales plan and forecast is the basis for good cash flow management and capacity planning. If the sales figures are below plan, the sales manager will increase the sales efforts in order to compensate these deviations. Usually, it can be expected that these efforts should be at least partly successful in the consumer markets. This situation is expected to be different in the industrial markets, as usually the generation of sales turnover can only be achieved by either new customers or new products sold to existing customers. It is therefore expected not to be possible to immediately compensate a loss of sales turnover within the planning period by increased sales efforts. This research project investigated whether industrial markets react differently from consumer markets by investigating the sales planning and forecasting process in the Machinery & Equipment Industry, the Automotive Supplier Tier 1 and the Automotive Supplier Tier 2 Industry. It investigated several time aspects of the sales process, displayed as customer-supplier interaction. The results of the research project showed that in fact sales processes in the investigated industry sectors have such a long duration, that it is not possible for sales managers to immediately compensate low sales figures by increased sales efforts. The sales turnover raise will come in a later period and thus simply too late for the current one. This results in the fact that the reliability of the sales forecast (for the established sales plan) is reduced, if industry characteristics and special time aspects of the sales process are not taken into consideration. These time aspects can be described best by the Market Response Time (MRT). The MRT is defined as the time lag between the start of an increase of sales efforts by the supplier (first contact) and the market response in terms of increased purchase. This is at the time when the customer starts to financially respond, with the result of a sales turnover increase at the supplier’s side. If the MRT is long, sales planning and forecasting has increased importance, because sales efforts need to be planned well in advance. For this reason response times are major elements in planning and forecasting, although it was previously not very well recognised in literature and practice. Based on a qualitative empirical study with the case study methodology, 41 case studies were undertaken within the three industry sectors. The investigated companies showed that these three industry sectors have different MRTs, such as 68 weeks in the Machinery & Equipment Industry, 138 weeks in the Automotive Supplier Tier 1, and 62 weeks in the Automotive Supplier Tier 2 Industry. These different MRTs influence the companies planning and forecasting processes in different ways. This research project qualitatively showed that if time aspects were taken into consideration in sales planning and forecasting, forecast accuracy could improve. It was furthermore indicated that an adequate sales planning approach could improve forecast accuracy as well. In a second step, it was indicated that these companies, which are aware of the time aspects, have shown a better sales performance in terms of sales force productivity, growth of productivity and market position. Concluding it can be stated that the respect of time aspects, such as MRT, may increase sales performance. The study's results have some limitations, which are the research context and the research methodology. As the project only investigated the industrial context, namely the Machinery & Equipment and the Automotive Tier 1 Supplier and Tier 2 Supplier Industry, its results can only be applicable to this context. The research methodology of this project is a qualitative one, which means that the sample size is small but deep and statistical generalisations cannot be made. Based on this, further research implications of this project are that its results may further be statistically generalised by quantitative studies. Especially the sales planning and forecasting processes in the detected clusters per industry sector should be investigated on a broad sample. Thirdly, the indicated relation between market knowledge and accuracy should be further investigated. This is because it can be estimated that the forecast accuracy is the highest if the company’s information horizon is equal to the product life cycle time of the products produced. Last of all, as there are only a few research projects done in the industrial context regarding market response models and time aspects, therefore these topics should be further investigated.

Cette thèse en micro-économie du développement s'articule autour de l'objectif de développement durable numéro 16 visant à «promouvoir l'avènement de sociétés pacifiques et inclusives aux fins du développement durable, assurer l'accès de tous à la justice et mettre en place, à tous les niveaux, des institutions efficaces, responsables et ouvertes à tous ». Elle propose d'étudier, à partir de données d'enquêtes originales et de première main, les interactions et les effets de la Gouvernance, la Paix et la Sécurité pour les ménages et les entreprises des pays d'Afrique subsaharienne. Ce projet s'articule autour de deux axes de recherche. Le premier, transversal et méthodologique, interroge la fiabilité des données utilisées. En effet, ces données portent, d'une part, sur des sujets sensibles (respect des droits fondamentaux, démocratie, corruption…) et d'autre part, elles ont été recueillies par des opérateurs publics : les instituts nationaux de la statistique. Les résultats de ce premier chapitre montrent que les instituts publics sont totalement légitimes pour collecter des données de gouvernance : aucun biais de réponse systématique en faveur (ou en défaveur) des pouvoirs publics n'existe quand les enquêtés sont interrogés par des agents d'organisation publique. Le second axe étudie les conséquences micro-économiques de la violence au travers de deux études de cas. Le deuxième chapitre porte sur la violence d'ordre politique et ses effets sur le capital social au Mali depuis le début du conflit en 2012. L'exposition aux violences renforce les liens forts, exclusifs entre individus d'une même communauté, aux détriments des liens inter-groupe dits faibles, inclusifs qui déterminent le développement économique et social individuel et local. Ce repli sur soi est probablement un facteur de l'enracinement des tensions inter-ethniques qui ont explosé après 2016. Enfin, le dernier chapitre analyse les effets de la violence criminelle sur le marché du travail informel à Madagascar. Alors que les victimes de criminalité ajustent relativement peu les conditions de leur travail, la peur de la violence criminelle, largement partagée dans la société malgache, impacte négativement la productivité des ménages agricoles. Ces derniers adoptent des comportements plus risqués sur le marché du travail. Cette inquiétude a deseffets sur les plus jeunes dont le temps de travail augmente
This dissertation in applied development microeconomics centres on Sustainable Development Goal 16 which “promote[s] just, peaceful and inclusive societies”. This work aims at studying the interactions and effects of Governance, Peace and Security through the analysis of first-hand and high-quality household survey data in SubSaharan Africa. It is built around two lines of research. The first line of research is cross-cutting and methodological: it questions the reliability of the data used. Indeed, public organisations, namely National Statistics Offices, administer the surveys and collect information of sensitive nature (dealing with respect of fundamental rights, democracy, corruption among other things). Results show no systematic self-censorship or attenuation bias from adults surveyed by NSOs compared with adults surveyed by independent organisations. We provide evidence of the capacity and legitimacy of government-related organisations to collect data on governance, at much higher levels of precision than other existing data sources. The second line of research focuses on the impacts of violence in two African countries. On the one hand, we study the impacts of political violence on social capital since 2012 in the case of the Malian conflict. The increased association participation in areas exposed to violent events cannot be considered as positive. Indeed, it is observed solely for family and political associations, which are comparatively inward-looking and act as interest groups. We interpret this finding as a form of withdrawal behind group or community boundaries which may exacerbate ethnic divisions and deepen the conflict. On the other hand, I study how workers of the informal labour market cope with criminal violence in Madagascar. Although victims of criminality seem not to adopt different behaviours on the labour market, the fear of crime impact productivity negatively, particularly in the agricultural sector. Fearful workers become more vulnerable to shock occurrence. Adults’ fear of criminal violence also channels to under 15 household members whose participation on the labour market increases

In this paper, we discuss the question whether or not the real estate market is efficient. We define market efficiency and the efficient market hypothesis as it had been developed in the literature on financial markets. Then, we discuss the empirical evidence that exists concerning the efficiency or inefficiency of financial markets, usually seen as the reference markets as far as market efficiency is concerned. In a separate section, we turn to the real estate market. There, we define the real estate market and discuss various aspects that are decisive for the efficiency of that market. As it turns out, the result found in the literature is inconclusive. Majority of studies provide evidence supporting inefficiency of the real estate market while several studies maintain the notion of real estate market efficiency.

Background: Biological medicines are effective but expensive options for treating patients with chronic and life-threatening diseases unresponsive to conventional small molecule medicines. The importance of biosimilars as an alternative to expensive originator biologics in treatment regimens is increasing year by year. This thesis aimed to examine the prescribing pattern of current marketed biosimilars and understand the potential factors influencing their prescribing in UK. Methods: Examples of generic medicines entry were analysed and compared and contrasted with the entry of biosimilars in both primary and secondary care settings. Web-surveys were conducted with 234 healthcare professionals (HCPs) and 182 service users to investigate their knowledge and attitudes towards biosimilars. Face-to-face semi-structured interviews were then conducted with 26 HCPs and service users to further elucidate interviewee’s perceptions of biosimilars. Results: Findings from the market analyses showed that the penetration of a generic and/or a biosimilar is governed by the cost, the number of products (competitors) and chronicity of use when the delivery devices are the same. When delivery device or another factor influencing prescribers’ perceptions of patient benefit differed, biosimilar uptake was inhibited. The findings from web surveys and interviews showed that both HCPs and service users had a good knowledge and understanding of biosimilars and their importance for cost savings. Concerns about safety and efficacy of biosimilars during the process of switching to biosimilars were expressed by HCPs and services users, although the extent of this concern varied with the clinical discipline. Conclusion: The introduction of biosimilars is associated with considerable cost savings to the NHS. There are subtle differences between specialists’ views on biosimilars and different uptake patterns. Factors influencing prescribing biosimilar medicines were similar but more complicated than generic medicines. Cost is a key driver for the uptake of biosimilars only when patients related factors were justified or equal.

Crowdsourcing is a new phenomenon, giving companies the ability to tap into the wisdom of crowds in order to solve complex problems, often at a fraction of the cost. In this document, the viability of crowdsourcing from the supply side is investigated with a market research questionnaire at the core of the research. Firstly, an overview of the current online crowdsourcing landscape is given with a focus on the big players, followed by a literature study on the motivation of solvers and their associated compensation needs. Because of the nature of crowdsourcing, an assumption is made that knowledge workers will be the biggest contributors in the form of solvers; this presumption is demonstrated by analysing responses to the questionnaire. The following research question is answered: What are the needs and profile of the solvers (supply side) of an internet platform that uses the principle of crowdsourcing to solve complex problems? It also answers the questions of many online crowdsourcing enthusiasts with regards to the typical solver and what their needs are, specifically with regards to compensation structures on these platforms. The typical solver profile was found to be predominantly male between the ages of 19 and 37, with a tertiary education or busy earning a degree of some sort and a strong will to become wealthy through applying this knowledge. These typical solvers have a primary objective to earn money with 100 per cent of the incentive paid to one „winner‟. They will participate more than three times even if they do not „win‟ the challenge and expect to earn more that R1 000 but less than R10 000 per day for this type of work. Certain limitations of the study are also addressed, like the clear self-selection bias and difficulty to generalise the findings to a well-defined group of people, as became evident from analysing questionnaire findings.
