Résumé :

Abstract Recent studies of correlations in Chinese stock market have mainly focused on the static correlations in financial time series, and then we pay great attention to investigate their dynamic evolution of correlations. Our paper reports on topology of 41 AH-shares companies traded on Shanghai and Hong Kong Stock Exchange in Chinese stock market. We apply the concept of minimum spanning tree (MST) and hierarchical tree (HT) to analyze and reveal the dynamic evolution of correlations between different market sectors for the period 2008–2014. From these trees, we can detect that significantly industry clustering effects are in the stock network. We measure the linkage of different companies geared to different industrial sectors. We observe the evolution of AH-shares companies in the stock network based on the moving window technique and investigate the correlations by calculating the correlation coefficient distribution, mean correlation coefficient and mean distance of these companies with time. Therefore, through our analysis, we find that companies working in the same branch of production tend to make up cluster. The results present the difference and similarity between different industry sectors in different time periods.

Résumé :

Shares price fluctuations cause investors to take irrational actions. An assessment of investment valuation is needed to deal with market fluctuations so as to reduce investment risk. Benjamin Graham Formula is an investment strategy by comparing the fair value of the shares with the shares price to help investors in making investment decisions. Benjamin Graham's value investing strategy is a strategy of valuing shares whose actual value is higher than market value, thereby finding significant returns over the long term. This research is quantitative descriptive. Based on the selection criteria for the Benjamin Graham method, the researcher suggests buying ADES shares. The firms share price is currently undervalued. CEKA shares have an undervalued value, this can be used as an alternative consideration in making investment decisions.

Texte intégral

Résumé :

Several researchers have over the past decades criticised the efficient market hypothesis as several studies have presented evidence of causality and co-integrating relationships in inancial markets. As preference shares have become increasingly popular, in recent years, as a mean of raising capital in the Swedish real estate sector, this study investigates the causal relationships between common shares and their corresponding preference share of nine listed Swedish real estate companies. By using daily closing prices over the period Dec 2014 – April 2016, we find weak support for short-run causalities in five of the nine examined pairs but no long-run cointegrating relationships. Further, we find causality running from the largest five firms to the four smallest in the sample firms. These findings violate the weak form of the efficient market hypothesis, which state that asset price fluctuations are random and not possible to forecast by the use of historical asset prices.

Résumé :

L’objectif de cette thèse CIFRE, réalisée avec la société d’études de marché BVA en collaboration avec le constructeur automobile Renault, est de mesurer l’impact des investissements media pour différents canaux (télévision, affichage, etc.) sur les parts de marché de différentes marques, en prenant en compte la concurrence et les potentiels effets croisés et synergies entre ces marques, ainsi qu’en tenant compte du prix des véhicules, du contexte réglementaire (i.e. prime à la casse), et des effets retard de la publicité.Nous avons puisé dans les littératures marketing et statistique pour développer, comparer et interpréter plusieurs modèles qui respectent la contrainte de somme unitaire des parts de marché. Une application concrète au marché automobile français est présentée, pour laquelle nous montrons que les parts de marché des marques sont plus ou moins sensibles aux investissements publicitaires consentis dans chaque canal, et qu’il existe de synergies entre certaines marques
The aim of this CIFRE thesis, realized with the market research institute BVA in collaboration with the automobile manufacturer Renault, is to build a model in order to measure the impact of media investments of several channels (television, outdoor, etc.) on the brands’ market shares, taking into account the competition and the potential cross effects and synergies between brands, as well as accounting for the price, the regulatory context (scrapping incentive), and the lagged effects of advertising. We have drawn from marketing and statistical literatures to develop, compare and interpret several models which respect the unit sum constraint of market shares. A practical application to the French automobile market is presented, for which it is shown that brands’ market shares are more or less sensitive to advertising investments made in each channel, and that synergies between brands exist

Texte intégral

Résumé :

This master thesis focuses on regional shopping centre’s market shares. It is written in cooperation with IKEA Centres that provided data regarding their shopping centres and funds for the gathering of statistics. The research question for the study is: What level of market share is valid for regional shopping centres in close proximity to an IKEA warehouse? In order to answer this question as accurate as possible the study is designed as a case study. The case is implemented on three different shopping centres, owned by IKEA Centres, with similar locations and market areas. The three shopping centres that are selected as subject centres in the study are Birsta City in Sundsvall, I-Huset in Linköping and Erikslund Shopping Center in Västerås. The case is focused on the regional shopping centres isolated and do not include the IKEA furniture store. The first part of the study concerns the delineation of the subject centres’ primary- and secondary market area. This is done using Reilly’s Law based on the prerequisites of the specific shopping centre. By using this method breaking points or borders of the market areas can be defined and located based on the calculated driving time. To be able to calculate the potential market shares for the centres, the buying power segmentation method is used. The statistics are bought from Statistics Sweden and concerns mainly the number of households in the market areas and their disposable income. The market share is calculated by comparing the potential buying power of the households and the actual sales in the shopping centres. The results of the conducted study regarding the market share in the total market area is that Birsta City has a significant larger market share (60%) than the two other centres that the study concerns. I-Huset (17% market share) and Erikslund Shopping (25% market share) are located in regions with a higher population and more competition, the authors see this as the main factor to the difference in the market share. Results regarding market shares in different categories of goods are also presented. The three subjects’ centres offer several different collections of items. All centres have a large market share in the fashion segments that are offered, a wide tenant mix in combination with the target groups is seen to be an effecting factor.
Denna masteruppsats fokuserar på ämnet regionala shoppingcenters och dess marknadsandel. Uppsatsen är skriven i samarbete med IKEA Centres vilka har bidragit med data angående köpcentren samt medel för inköp av statistik. Studiens frågeställning är: Vilken marknadsandel har regionala köpcenter där ett Ikeavaruhus finns i närheten? För att besvara denna frågeställning på bästa sätt är studien utformad som en fallstudie. Fallstudierna är implementerade på tre olika shopping center i liknande läge och med likvärdiga marknadsområden. De tre köpcentrumen vilket är utvalda som ämnescenter i studien är Birsta City i Sundsvall, I-Huset i Linköping och Erikslund Shopping Center i Västerås. Forskningen är baserad på shopping centret och berör inte IKEAs möbelvaruhus. Den första delen av studien behandlar avgränsningen av köpcentrumens primära och sekundära marknadsområden. Avgränsningen är utförd med Reilly’s Law baserad på de specifika köpcentrets förutsättningar. Genom att använda den här metoden definieras brytpunkter och gränser för marknadsområdet kan avgränsas med hjälp av den beräknade körtiden. För att sedan beräkna köpcentrets marknadsandel används metoden ”Buying power segmentation method”. Statistiken som används är köpt från SCB och berör huvudsakligen antalet hushåll i marknadsområdena samt dess disponibla inkomst. Marknadsandelen är beräknad genom att jämföra den potentiella köpkraften hos hushållen med den faktiska försäljningen i köpcentren. Resultatet av den utförda studien rörande marknadsandelar av den totala marknaden är dels att Birsta City har en betydligt större marknadsandel (60%) än de två andra undersökta köpcentren. I-Huset (17% marknadsandel) samt Erikslund Shopping (25% marknadsandel) är belägna i regioner med högre invånarantal och större konkurrens. Författarna ser detta som en avgörande faktor till skillnaden i marknadsandel jämfört med Birsta City. Resultat angående marknadsandelar i olika kategorier av varor är också presenterade. De tre studerade köpcentren erbjuder ett brett utbud av produkter. Samtliga center har en stor marknadsandel i kategorier rörande kläder & mode. Den breda hyresgästmixen samt målgruppen för köpcentren antas vara påverkande faktorer till detta.

Résumé :

Mestrado em Decisão Económica e Empresarial
Com a realização deste estudo procurou-se aferir a influência da comunicação social na tomada de decisão no momento de comprar e vender acções, determinando quais as notícias que mais influenciaram a tomada de decisão. O estudo ao índice PSI 20. Os dados que permitiram a realização do estudo foram recolhidos no período de 15-12-2008 a 16-05-2011 tendo sido consideradas todas as notícias presentes na primeira página do Jornal de Negócios e Diário Económico e as cotações de fecho em bolsa dos títulos da EDP, ALTRI SGPS e BES, empresas estas que se encontram ambas cotadas no índice PSI 20. A análise foi iniciada com a categorização das notícias recolhidas, através do software IBM SPSS Modeler. Após a conclusão deste processo e tendo em conta a possível relação existente entre algumas das categorias, foi utilizada a análise das componentes principais, tendo sido obtidos componentes formados por duas ou mais categorias, que na prática podem ser vistas como temas de notícias publicadas nos referidos jornais. Por fim e com o intuito de aferir a relação existente entre as componentes obtidas e as decisões dos investidores, os dados existentes foram analisados através de uma regressão linear múltipla, utilizando para o efeito o software IBM SPSS Statistics, que permitiu constatar que a decisão de compra e venda de acções é influenciada por notícias relacionadas com a crise actual, por negócios inerentes à compra ou venda de uma percentagem considerável de participações de empresas nacionais e por casos de crime e corrupção mediáticos em Portugal.
The goal of this work is to review and prove the existence of influence of the social communication on decision making when buying or selling market stocks and to determine which news influence such decisions. The work was applied in the real conditions of the Portuguese market and its primary stock market index PSI 20. The necessary data for this study was collected between 15 December 2008 and 16 May 2011 including three major stocks EDP, ALTRI SGPS and BES and all the related news published on the first pages of the most influent Portuguese economical-financial journals, namely Jornal de Negócios and Diário Económico. At the beginning of the analysis, the collected data has been categorized with the IBM SPSS Modeler. After concluding this process, having in mind that relations may exist among some categories, the component analysis was performed. Naturally there were components formed by two or more categories which can be seen as different topics published in referred journals. Finally, in order to assess an existing relationship between obtained components and decisions made by investors, the data was analysed through a multiple linear regression using IBM SPSS Statistics. This analysis allowed to conclude that a decision whether to buy or sell a stock is influenced by news related to the actual financial crisis on the world market, by news inherent to a purchase or disposal of considerable amount of participations owned by large national companies and by "medialized" cases of crime and corruption in Portugal.

Résumé :

Master in International Economics and European Studies
This paper aims to examine the Competitiveness of China and India in the European Union based on the international trade values, during the time period 2001- 2009. It firstly reflects about the ambiguous definition of Competitiveness as well as the diversity of methods that exist to measure this concept. Subsequently, the following work seeks to analyse the exports growth of China and India in particular to the European market. Therefore, some methodologies were used in this paper: the Revealed Comparative Advantage analysis, which seeks to capture the products where China and India present Comparative advantage at world’s level; the Constant Market Share analysis, which pretends to verify if the Competitiveness explain the export growth to the European market; and the analysis based on the combination of the Trade Complementarity Index with the Geographical Orientation Index, which permits to identity the products where there is room, for China and India, to expand their exports to the European Union, under certain circumstances. The empirical analysis suggests that China’s and India’s exports are competitive in products identified by the three methodologies, having in many of them capacity to increase their exports to the European market. However, there still persist high levels of trade protection applied by the European Union, which can explain why China’s and India’s exports have not yet take advantage of their full potential.

Résumé :

We design, implement and evaluate statistical methods for managing uncertainty when consuming and provisioning resources in a federated computational market. To enable efficient allocation of resources in this environment, providers need to know consumers' risk preferences, and the expected future demand. The guarantee levels to offer thus depend on techniques to forecast future usage and to accurately capture and model uncertainties. Our main contribution in this thesis is threefold; first, we evaluate a set of techniques to forecast demand in computational markets; second, we design a scalable method which captures a succinct summary of usage statistics and allows consumers to express risk preferences; and finally we propose a method for providers to set resource prices and determine guarantee levels to offer. The methods employed are based on fundamental concepts in probability theory, and are thus easy to implement, as well as to analyze and evaluate. The key component of our solution is a predictor that dynamically constructs approximations of the price probability density and quantile functions for arbitrary resources in a computational market. Because highly fluctuating and skewed demand is common in these markets, it is difficult to accurately and automatically construct representations of arbitrary demand distributions. We discovered that a technique based on the Chebyshev inequality and empirical prediction bounds, which estimates worst case bounds on deviations from the mean given a variance, provided the most reliable forecasts for a set of representative high performance and shared cluster workload traces. We further show how these forecasts can help the consumers determine how much to spend given a risk preference and how providers can offer admission control services with different guarantee levels given a recent history of resource prices.

Résumé :

Mestrado em Economia e Estudos Europeus
No decurso dos últimos 20 anos do século passado, a China foi alcançando, gradualmente, uma posição proeminente nas trocas comerciais internacionais e, actualmente, essa trajectória em direcção a uma maior proeminência parece acentuar-se. As históricas relações económicas entre a China e a União Europeia deparam-se hoje com o início de uma nova era. Um dos eventos que esteve no centro desta mudança foi o acesso da China à Organização Mundial do Comércio, em Dezembro de 2001. Como consequência, numerosas barreiras ao comércio e ao investimento encontram-se em processo de supressão e, como resultado, assiste-se à criação de novas oportunidades comerciais e de investimento. No presente trabalho, é efectuada uma análise quantitativa da competitividade da China na UE15 entre 1999 e 2004, pelo estudo de fluxos de comércio e pela interpretação de indicadores de competitividade. É ainda analisado, nas exportações da China para a UE15, o "efeito competitividade" determinado pela metodologia das Quotas de Mercado Constantes (Constant Market Shares Analysis). São também identificados riscos e oportunidades para alguns sectores de actividade considerados relevantes na indústria europeia face ao crescente peso da economia chinesa na economia mundial, relativamente aos quais é, também, efectuada uma análise das tendências e dos desenvolvimentos da indústria chinesa. Adicionalmente, sugerem-se orientações a adoptar por parte da indústria europeia, a fim desta manter ou, mesmo, ganhar vantagens nos sectores abordados.
In the past 20 years, China has, gradually, achieved an outstanding part in international trade and, today, that position is being emphasized. The economic relations between China and the European Union are now on the edge of a new era. One of the events at the core of this change was China's accession to the World Trade Organization, in December, 2001. As a result, barriers to commerce and investment are been suppressed and, consequently, new opportunities in those two areas are emerging. This dissertation analyses the competitiveness of the Chinese economy in EU15 between 1999 and 2004, based on trade patterns and on competitiveness indexes. The exports of China to EU15 are also analysed using the Constant Market Shares Analysis, with special interest on the "competitiveness effect". Opportunities and threats are identified for some European industries; as well as the impact the Chinese economy might have in them, considering trends and developments concerning to those industries. Additionally, some guidelines are suggested for those European industries to maintain or, even, to obtain advantages.

Résumé :

In the case of markets characterized by a stationary primary demand, the relevant dimension for measuring a company’s success is represented by market shares. The paper aims to build and comment on a model that gauges the competitive effects of marketing maneuvers on market shares, with reference to tea-based beverages in Italy in the period November 2010 – October 2015. This analysis will be instrumental in establishing the effectiveness of marketing policies based on promotions or advertising. We estimate such a model on weekly data provided by IRI Infoscan and Nielsen, involving the top five brands in the Italian market. After a descriptive analysis and a stationarity test, we estimate a Multinomial Logit model, making use of the Seemingly Unrelated Regressions method. The results allow us to identify the effectiveness of each brand’s marketing policies. Moreover, they enable us to derive the matrices of direct and cross elasticities of brands’ market shares with respect to the main marketing tools (price, promotions, distribution, advertising investments) and to compare basic and average market shares. Based on these results, it is therefore possible to identify the market’s competitive structure, revealing the most incisive factors to be price and weighted distribution, while advertising investments are significant in only a few cases and elasticities are remarkably low. The competitive structure appears to be of a horizontal type (i.e., cross elasticities do not vary greatly).

Résumé :

Analysis of customer preferences is among the most important tasks in a new product development. How customers come to appreciate and decide to purchase a new product affects the products market share and therefore its success or failure. Unfortunately, when designers select a product concept early in the product development process, customer preference response to the new product is unknown. Conjoint analysis is a statistical marketing tool that has been used to estimate market shares of new product concepts by analyzing data on the product ratings, rankings or concept choices of customers. This paper proposes an alternative to traditional conjoint analysis methods that provide point estimates of market shares. It proposes two approaches to model market share uncertainty; bootstrap and binomial inference applied to choice-based conjoint analysis data. The proposed approaches are demonstrated and compared using an illustrative example.

Résumé :

Information in various markets constitutes the primary basis for making the right decisions in a modern and globalized world. Therefore, opportunities grow based on the availability of data and how the data is structured to obtain information that supports decision-making processes, Ogrean (2018) and Neubert (2018), and even more so when business dynamics revolve around satisfying the demand for the products or services offered, Jacobs and Chase (2009). This article proposes the analysis of the new vehicle market, through operational research techniques, addressing the behavior of vehicle sales for medium and long-term projections for business management. The analysis is developed through Markov Chains and time series analysis techniques, so a complementary approach is used to obtain predictions in future scenarios such as analysis in sales levels related to market shares. Choi et al (2018), indicate that one of the important applications of Big Data in business management is in the field of demand forecasts, becoming one of the common alternatives in prediction for data series over time. The data is taken from Statistics of the National Association of Sustainable Mobility, from 2016 to 2019 for new vehicles in the Colombian market, Andemos (2021). Merkuryeba (2019) proposes procedures between techniques that allow a comprehensive approach to forecasts and where the methods complement each other, it is through the use of the methodology in Markov chain models (Kiral and Uzun 2017), plus the methodology of the time series analysis (Stevenson et al 2015), which with a complementary approach, can reach a more detailed and comprehensive level of analysis for the statement about the future of the variable of interest: vehicle market sales for business management.The results showed that Markov chains were very useful in long-term analysis for sales forecasting and their analysis by market segmentation, for this the sales level is ranked according to the technique of Pareto. Another important contribution to the Markov chain in business management corresponds to the analysis disaggregated by sales rankings, for example in ranking 1 (first 5 brands), was obtained an expectation of value defined at 67.1% of the total sales level, also an internal analysis of this percentage ranking was carried out. Complementarily, for the alternative of times series analysis; we start from the analysis of the demand, where a seasonal behavior of vehicle sales is detected. Rockwell and Davis (2016) and Stevenson et al (2015), establish a procedure for estimating and eliminating seasonal components by using the seasonal index. Additionally, Weller and Crone (2012) and Lau et al (2018), recommend two common alternatives to measure forecast error and making decisions to selected the technique more adequate for business management: mean absolute deviation (MAD) and mean absolute percentage error (MAPE), finally, the result of the three techniques developed: moving average, exponential smoothing, and weighted moving average, the simple exponential smoothing, optimized through MAPE minimization is the selected technique, with which short and medium-term forecasts are defined.This study contributes directly to decision-making in the context of the marketing of new vehicles, as well as in academic settings in relation to research processes in data series under the configuration of big data. In this sense, it was demonstrate that the behavior of sales, segmented by market levels according to the participating brands, can be transformed into estimates of future behavior that establishes an orienting mapping of business objectives with respect to the possible level of participation in quotas of market. Finally, the methodological scheme under an epistemological perspective supported by technical decisions, represent an academic contribution of great relevance for business management, where is recommended to use the time series techniques for short and medium-term forecasts, while Markov chains for the prediction and analysis of the sales structure in medium to long term forecasts.

Résumé :

The crisis caused by the spread of the COVID-19 virus has affected companies listed on the stock exchange differently. While some actions have not been affected by the pandemic, others have declined sharply. Based on such a hypothesis, the objective of the research is to determine the extent to which the shares of companies listed on the Bucharest Stock Exchange were affected by the COVID-19 pandemic. The analysis period is between 01.01.2020 and 01.03.2021. For the shares that registered reductions of the market price, the period in which they reached the mini-mum value was established. Next, the average period was established in which their exchange rate returned to the value of January 2020. The research followed the dynamics of the listed shares from the point of view of the activity carried out and a ranking of them was made.

Résumé :

The paper presents the results of the analysis of NUTS 2 regions with a focus on the regions of Visegrad countries. The aim is to assess the level of development of the regions in the area of Knowledge Intensive Business Services (KIBS) in relation to their economic level and position within the regions of the EU. The division of regions into groups was based on the clustering method, including Ward's method for determining the number of groups. Furthermore, the correlation between employment shares in KIBS and the level of economic development of the regions was examined. The resulting data confirms a statistically significant dependence between GDP per capita and the aggregate indicator of employment share in KIBS, especially in the sub-areas of knowledge market services and high-technology services.

Résumé :

Selecting optimum concepts for a system and its subsystems in the conceptual design stage involves uncertainties due to imperfect information about customer preferences (market shares), cost of the system developed from each concept, and feasibility of new technology used in the new system. When analytical relationships between system performance and system inputs or parameters are unknown in the early system development stage, one approach to quantify the goodness of a concept is to use rating scales. This paper studies the effects of variations (precisions) in rating scales and in cost estimation for evaluating the goodness of system module concepts (e.g., sub-systems, assemblies, subassemblies, and parts). This paper presents a global sensitivity analysis (GSA) in perceptual concept evaluation, three probability measures for evaluating and selecting optimum concepts in GSA, and one-set-of-factors-at-a-time GSA to identify the sets of factors that cause significant variations in concept evaluation outcomes.

Texte intégral

Résumé :

We document a strong empirical connection between corporate taxation and the manufacturing labor share, both in the US and across OECD countries. Our estimates associate 30 percent to 60 percent of the observed decline in labor shares with the fall in corporate taxation. Using an equilibrium model of an industry where firms differ in their capital intensities, we show that lower corporate tax rates reduce the labor share by raising the market share of capital-intensive firms. The tax elasticity of the labor share depends on the joint distribution of labor intensities and value added at the micro level. Given the empirical distribution in the US manufacturing sector, our quantitative analysis suggests that corporate tax cuts explain a significant part of the decline in the manufacturing labor share since the 1950s. The shift away from traditionally large, labor-intensive production units raised the concentration of market shares and reduced the concentration of employment.

Résumé :

Agriculture is an important source of employment in Latin America and the Caribbean. In rural areas, some 54.6 per cent of the labour force is engaged in agricultural production. Although much of the region shares the same language and cultural heritage, the structure and scale of the agriculture sector varies significantly from country to country. Based on the review of 131 digital agriculture tools, this report, prepared by GSMA and IDB Lab, provides a market mapping and landscape analysis of the most prominent cases of digital disruption. It highlights some of the major trends observed in five digital agriculture use cases, identifies opportunities for digital interventions and concludes with recommendations for future engagement that could deliver long-term, sustainable economic and social benefits for smallholder farmers.

There is no commodity whose interlinkages with the macroeconomy have been studied as extensively as oil, starting with Hamilton’s (1983) seminal study. Thousands of subsequent studies have examined the relationship between oil prices and various economic variables, including the stock market. This strand of the literature began with the pioneering work of Kling (1985). Since then, other financial markets, such as banking, have also received a fair share of analysis.

Résumé :

The agricultural sector plays a crucial role in Guyanas economic development by contributing 21.15% of gross domestic product (GDP). However, the share of the agricultural sector has been gradually decreasing over the years. This monograph offers an update of the OCDEs Producer Support Estimate (PSE) methodology applied to Guyana for 2015-2019. The PSE approach focuses on two main elements of support: (i) the effect of government policy on prices received by agricultural producers, and (ii) the support provided through budgetary transfers to the sector. The market price support (MPS) remained Guyanas main PSE component. Expressed as a share of the total PSE, Guyanas MPS averaged 59% between 2015 and 2018. Following the end of Government transfers to GuySuCo in 2019, which led to a sharp decline in budget transfers to the agricultural sector, it rose to 96%. The main driver of Guyanas MPS remained the import duties in place to protect domestic producers of poultry meat. This report also documents the evolution of agricultural policies-related greenhouse gas emissions in Guyana for the first time. The poultry subsector, which receives most of the policy support in Guyana, emits little. Sugar and rice, on the other hand, are the commodities with the highest GHG emissions per hectare. To conclude, several policy recommendations are presented.

Texte intégral

Résumé :

Original objectives: The overall goal of the proposal was to determine the genetic and molecular control of pathways leading to the production of secondary metabolites determining major fruit quality traits in pepper. The specific objectives were to: (1) Generate a molecular map of pepper based on simple sequence repeat (SSR) markers. (2) Map QTL for capsaicinoids content (3) Determine possible association between capsaicinoids and carotenoid content and structural genes for capsaicinoid and carotenoid biosynthesis. (4) Map QTL for quantitative traits controlling additional fruit traits. (5) Map fruit-specific ESTs and determine possible association with fruit QTL (6) Map the C locus that determines the presence and absence of capsaicinoids in pepper fruit and identify candidate genes for C. Background: Pungency, color, fruit shape and fruit size are among the most important fruit quality characteristics of pepper. Despite the importance of the pepper crop both in the USA and Israel, the genetic basis of these traits was only little known prior to the studies conducted in the present proposal. In addition, molecular tools for use in pepper improvement were lacking. Major conclusions and achievements: Our studies enabled the development of a saturated genetic map of pepper that includes numerous simple sequence repeat (SSR) markers and the integration of several independent maps into a single resource map that consists of over 2000 markers. Unlike previous maps that consisted mostly of tomato-originated RFLP markers, the SSR-based map consists of largely pepper markers. Therefore, the SSR and integrated maps provide ample of tools for use in marker-assisted selection for diverse targets throughout the Capsicum genome. We determined the genetic and molecular bases of qualitative and quantitative variation of pungency, the most unique characteristics of pepper fruit. We mapped and subsequently cloned the Pun1 gene that serves as a master key for capsaicinoids accumulation and showed that it is an acyltransferase. By sequencing the Pun1 gene in pungent and non-pungent cultivars we identified a deletion that abolishes the expression of the gene in the latter cultivars. We also identified QTLs that control capsaicinoids content and therefore pungency level. These genes will allow pepper breeders to manipulate the level of pungency for specific agricultural and industrial purposes. In addition to pungency we identified genes and QTLs that control other key developmental processes of fruit development such as color, texture and fruit shape. The A gene controlling anthocyanin accumulation in the immature fruit was found as the ortholog of the petunia transcription factor Anthocyanin2. The S gene required for the soft flesh and deciduous fruit nature typical of wild peppers was identified as the ortholog of tomato polygalacturonase. We identified two major QTLs controlling fruit shape, fs3.1 and fs10.1, that differentiate between elongated and blocky and round fruit shapes, respectively. Scientific and agricultural implications: Our studies allowed significant advancement of our understanding at the genetic and molecular levels of important processes of pepper fruit development. Concomitantly to gaining biological knowledge, we were able to develop molecular tools that can be implemented for pepper improvement.

Résumé :

Genetic analysis and mapping in grapes has been difficult because of the long generation period and paucity of genetic markers. In the present work, chromosome linkage maps were developed with RAPD, RFLP and isozyme loci in interspecific hybrid cultivars, and RAPD markers were produced in a V. vinifera population. In three cultivars, there were 19 linkage groups as expected for a species with 38 somatic chromosomes. These maps were used to locate chromosome regions with linkages to important genes, including those influencing powdery mildew and botrytis bunch rot resistance; flower sex; and berry shape. In V. vinifera, the occurrence of specific markers was correlated with seedlessness, muscat flavor and fruit color. Polymorphic RAPD bands included single copy as well as repetitive DNA. Mapping procedures were improved by optimizing PCR parameters with grape DNA; by the development of an efficient DNA extraction protocol; and with the use of long (17- to 24-mer) primers which amplify more polymorphic loci per primer. DNA fingerprint analysis with RAPD markers indicated that vinifera cultivars could be separated readily with RAPD profiles. Pinot gris, thought to be a sort of Pinot noir, differed by 12 bands from Pinot noir. This suggests that while Pinot gris may be related to Pinot noir, it is not likely to be a clone. The techniques developed in this project are now being further refined to use marker-assisted selection in breeding programs for the early selection of elite seedlings. Furthermore, the stage has been set for future attempts to clone genes from grapes based upon map locations.

Texte intégral

Résumé :

This paper analyses the ability of banks to use voluntary and regulatory capital buffers, taking advantage of the experience of the COVID-19 pandemic. In the first place, we find that the usability of macroprudential buffers is not hampered in Spain by other parallel banks’ requirements. Additionally, we find that the existing voluntary buffers over capital requirements at the beginning of the pandemic have had significant effects on the financial markets, affecting the evolution of European bank stock prices, as well as the holdings of bank shares by investment funds. Lastly, we find no significant aggregate effect of voluntary capital buffers on the provision of financing to non-financial companies in Spain. However, we do identify negative effects in the supply of credit from banks with lower voluntary buffers to companies with which they had more recent relationships. Likewise, if the analysis is carried out exclusively on credit operations without public guarantees, we observe that those banks with lower voluntary capital buffers reduced credit more.

Texte intégral

Résumé :

Meiotic recombination is a process in which homologous chromosomes engage in the exchange of DNA segments, creating gametes with new genetic makeup and progeny with new traits. The genetic diversity generated in this way is the main engine of crop improvement in sexually reproducing plants. Understanding regulation of this process, particularly the regulation of the rate and location of recombination events, and devising ways of modifying them, was the major motivation of this project. The project was carried out in maize and wheat, two leading crops, in which any advance in the breeder’s toolbox can have a huge impact on food production. Preliminary work done in the USA and Israeli labs had established a strong basis to address these questions. The USA lab pioneered the ability to map sites where recombination is initiated via the induction of double-strand breaks in chromosomal DNA. It has a long experience in cytological analysis of meiosis. The Israeli lab has expertise in high resolution mapping of crossover sites and has done pioneering work on the importance of epigenetic modifications for crossover distribution. It has identified genes that limit the rates of recombination. Our working hypothesis was that an integrative analysis of double-strand breaks, crossovers, and epigenetic data will increase our understanding of how meiotic recombination is regulated and will enhance our ability to manipulate it. The specific objectives of the project were: To analyze the connection between double-strand breaks, crossover, and epigenetic marks in maize and wheat. Protocols developed for double-strand breaks mapping in maize were applied to wheat. A detailed analysis of existing and new data in maize was conducted to map crossovers at high resolution and search for DNA sequence motifs underlying crossover hotspots. Epigenetic modifications along maize chromosomes were analyzed as well. Finally, a computational analysis tested various hypotheses on the importance of chromatin structure and specific epigenetic modifications in determining the locations of double-strand breaks and crossovers along chromosomes. Transient knockdowns of meiotic genes that suppress homologous recombination were carried out in wheat using Virus-Induced Gene Silencing. The target genes were orthologs of FANCM, DDM1, MET1, RECQ4, and XRCC2.

Alviarez, Vanessa. Global and Regional Value Chains in Latin America in Times of Pandemic. Inter-American Development Bank, novembre 2022. http://dx.doi.org/10.18235/0004524.

Texte intégral

Résumé :

Global value chains (GVCs) provide countries with opportunities to diversify trade, and boost productivity and growth by specializing in one stage of the production process. However, for the most part, Latin America and the Caribbean participation in GVCs remains low (18 percent) compared to Asia (28 percent) and Europe (34 percent). The COVID-19 pandemic, plus concerns regarding protectionism and the more frequent occurrence of natural disasters, have provided incentives for countries and companies to reassess their positions in global value chains. This crisis has taken a huge toll on trade, but it could also be an opportunity to boost regional integration and value chains within the region. Despite the crisis, some firms have performed well, even in those sectors where global demand has fallen, while others have lost market share. This paper analyzes the performance of individual firms, drawing on the study of rich micro data, to understand their different capacity of trade creation and destruction over the crisis. Results suggest five firm characteristics play a key role in explaining export performance during the pandemic: i) firm size, ii) diversification of export markets, iii) importer status of the firm, iv) distance from foreign suppliers, and v) performance of the firms suppliers and customers. The results are then used to outline policies fostering firms participation in global value chains.
