Information recueillie sur les marchés des drogues de synthèse est beaucoup moins avancée que les études sur d'autres marchés de drogues illicites. La classification relativement récente des drogues de synthèse comme substances illicites, couplée avec ses caractéristiques distinctes qui empêchent son observation, a entravé le développement d’évaluations complètes et fiables des caractéristiques structurelles des marchés. Le but de cet article est de fournir un aperçu fiable sur la dynamique interne du marché des drogues synthétiques, en particulier sur ses caractéristiques structurelles et organisationnelles. En utilisant l'information obtenue à partir de 365 drogues de synthèse saisies par les policiers pendant un an, cette étude sera la fusion de deux techniques, soit la composition des drogues illicites et des analyses économiques, afin de tirer des évaluations fiables des caractéristiques structurelles du marché du Québec de drogues synthétiques. Les résultats concernant l'analyse de la composition des drogues indiquent que le marché des drogues synthétiques au Québec est probablement composé d'un nombre élevé de petites structures, ce qui indique un marché compétitif. L'analyse économique a également fourni des informations complémentaires sur le marché des drogues. Selon la région géographique les couts de la production et les relations entre trafiquant et consommateur influencent le prix des drogues. Les résultats de cette recherche mettent l'accent sur la nécessité de concevoir des politiques qui tient compte des différences régionales dans la production de drogue et reflète la nature compétitive de ce marché. / Research gathered on synthetic drug markets trails behind studies on other illegal drug markets. Synthetic drug's relatively recent classification as an illicit substance, coupled with its distinct characteristics that insulate it from detection has hindered the development of reliable assessments of the markets structural features. The purpose of this study is to provide reliable insight into the inner dynamics of Quebec’s synthetic drug industry, focusing on its organizational features. Using information derived from 365 synthetic drugs seized by law enforcement over a one year period, this study will merge two techniques, drug composition and economic analyses, under a common framework to derive reliable and comprehensive assessments of the structure of Quebec's synthetic drug market. Drug composition analysis examines the drug’s chemical and physical profile to make inferences about the market structure while the economic analysis examines price determinants for the same market, providing further insight into its dynamics and distinctive features. Findings from the drug composition analysis indicate that the synthetic drug market in Quebec is likely to be composed of a high number of small structures, indicating a competitive market. The economic analysis provided complementary information, finding that both differential production costs and trafficker-consumer relations may influence price variations, depending on the region. This study concludes by emphasizing that drug composition analysis should be diligently pursued by both researchers and enforcement organizations alike to effectively target and enhance our understanding of the intricate processes that underlie the synthetic drug market.

Thus, we examined the relationship between concentration indicators (C3 and HHI), competition (H-statistic) and risk (NPL, Z-score) for the period comprehended between 2001 and 2013. The relationship between non-performing loans (NPL), concentration and competition was empirically tested using panel data models. The results indicates that bank concentration has a significant impact on the NPL, suggesting that more concentrated systems are more fragile. On the other hand, the results for competition and NPL indicates that a more competitive environment may generate a more stable financial system. / O presente trabalho analisou em que medida a estrutura de mercado da indústria bancária brasileira – em níveis de concentração e competição – afeta o apetite ao risco de seus agentes. Para tanto, o estudo examinou a relação entre indicadores de concentração (C3 e HHI), competição (Estatística-H) e de risco (NPL, Z-score) para o período entre 2001 e 2013. A relação entre non-performing loans (NPL), concentração e competição foi empiricamente testada através de modelos de dados em painel. Os resultados indicam que a concentração bancária tem impacto significativo no NPL, sugerindo que sistemas mais concentrados são mais frágeis. Por outro lado, os resultados para competição e NPL indicam que em ambientes mais competitivos podem gerar sistemas financeiros menos instáveis.

The role that banks as key intermediaries play in the modern economy activities is unquestionable, it is admitted that banks remain one of the key financial intermediaries that provide a variety of services in the economy of every state. However, not all financial intermediaries have a significant impact on modern economies, only a stable and profitable banking sector can adequately play the role of financial intermediary in economy. The bank, as an intermediary in the modern economy must be profitable, and this profitability depends on a number of factors that are referred to in this study as determinants of bank profitability. The effect of internal and external determinants of the bank profitability in South Africa is the main focus of this study. It utilized annual time series internal and external data for the period 2001 to 2013. Quantitative approach methodology using secondary data and panel data technique to measure the impact of the determinants was used in the study. The sample consists of nine banks, followed for 12 years and sampled annually. The results for bank-specific consist of four statistically significant variables such as bank size, non-interest income and non-interest expense and credit risk and four non-significant variables (equity capital, loan, saving deposit, fixe term deposit) also the industry-specific consist only one significant variable (market concentration) while macro-economic determinants consist of three non-significant variables (economic growth, inflation, and lending interest rate). In conclusion, the empirical result shows that the bank specific factors are directly controlled by the Management thereby it has a positive correlation to the bank profitability while the industry specific (market concentration) also positively affects the bank profitability. However, the macroeconomic variables which are beyond the scope of management control were non-significant to profitability but show positive sign. Therefore, the variables which are significant affect positively the bank profitability, and the non-significant variables affect the bank profitability negatively. The findings were consistent with mixed results found in prior literature. / Business Management / M. Com. (Business Management)

Cette thèse explore la dimension géographique des disparités entre les sexes dans le marché du travail. Les questions étudiées incluent la variation de la prime salariale urbaine entre les sexes (chapitre deux), l'exploration des différents mécanismes derrière les effets importants de la localisation géographique sur les gains du marché du travail des femmes (chapitre trois), et de l'écart entre les sexes sur les rendements d'expérience urbains (chapitre quatre). Le deuxième chapitre entreprend une analyse transversale à l'aide de données françaises pour estimer la prime salariale urbaine et sa variation entre les sexes. Les résultats confirment l'existence d'une prime salariale urbaine nettement supérieure pour les femmes. Un doublement de la densité de l'emploi dans une zone donnée entraîne une réduction de 2,4 pourcent de l'écart salarial entre les sexes, une valeur qui augmente de 4 pourcent lorsqu'on exclut la catégorie professionnelle des ouvriers. Contrairement au reste des professions, l'effet de la densité favorise les hommes dans la catégorie des ouvriers. Le troisième chapitre cherche à trouver les mécanismes à l'origine de l'effet importante de la localisation géographique sur les gains du marché du travail pour les femmes en employant l'approche par l'estimateur « within ». Les résultats suggèrent que la moitié de la prime salariale urbaine est attribuée sur la base d'un tri des travailleurs selon le type de compétences à travers des différentes zones. Cependant, en complément du tri de compétences, d'autres hétérogénéités individuelles contribuent également à l'excès de la prime salariale urbaine pour les femmes. / This dissertation explores the geographical dimension of the gender gaps in the labor market. The investigated issues include the variation of urban wage premium across genders (chapter two), exploration of different mechanisms behind stronger location effects for females' labor market gains (chapter three), and the gender gap in the urban returns to experience (chapter four). The second chapter undertakes a cross-sectional analysis by using French data to estimate the urban wage premium and its variation across genders. The findings confirm the existence of an urban wage premium that is significantly higher for women. A twofold increase in employment density of an area results in a 2.4 percent reduction in the gender wage gap, which increases to 4 percent when we exclude manual workers occupational category. Contrary to the rest of the occupations, the density effect favors men in the manual workers category. The third chapter seeks to find the mechanisms behind the stronger location effects on labor market gains for women by employing the within estimate approach. Results suggest that half of the urban wage premium is contributed by the sorting of workers according to skill type across different areas. However, in addition to skill sorting other individual heterogeneities also contribute to the excess urban wage premium for females. Firm level agglomeration effects attribute a minor part to the excess urban wage premium for females. The left over premium is a result of pure urban effects (lower discrimination, better matching, urban amenities).

Esta tese pesquisou a questão da reciclagem no Brasil, destacando quatro dos mais significativos resíduos sólidos recicláveis: as latas de alumínio, o papel, as garrafas polipolietileno-tereftalato (PET) e o vidro. Busca oferecer maiores subsídios sobre um tema que só recentemente tem sido melhor estudado, dada a sua ligação com o meio ambiente e a polêmica sobre o desenvolvimento sustentável. / This thesis researched about recycling in Brazil highlighting four of the most significatives recyclily solid residues, e.g. tin (aluminium) cans, paper, bottles made of polyethylene terephthalate (PET) and the glass. Due to its liaison with the environment and the controversies about the sustainable development, this thesis offer great subsidies about a theme that only recently has been deeply studied.

Seit den 90er Jahren ist die Wettbewerbsstruktur im europäischen Eisenbahngüterverkehr starken Veränderungen unterworfen. Die Auflösung staatlicher Monopole sowie die Öffnung nationaler Märkte implizieren einen intensivierten Wettbewerb, bieten jedoch gleichzeitig die Möglichkeit, sich über neuartige Formen der Allianzbildung Wettbewerbsvorteile zu sichern bzw. Eintrittschancen in neue Transportmärkte zu nutzen. Die Einführung wettbewerblicher Marktstrukturen im Eisenbahngüterverkehr betrifft einerseits die Schaffung gleicher Wettbewerbsvoraussetzungen im Verhältnis der Verkehrsträger untereinander (intermodal). Weiterhin steht die Einführung von Wettbewerb zwischen Eisenbahnverkehrsunternehmen im Vordergrund (intramodal). Die vorliegende Arbeit betrachtet Allianzmöglichkeiten entlang beider Dimensionen: im Mittelpunkt stehen Partnerschaften zwischen Eisenbahnverkehrsunternehmen und/oder intermodalen Partnern, die grundsätzlich auf die Gestaltung des intramodalen Wettbewerbs ausgerichtet sind. Aufgrund des Einbezugs intermodaler Partner, der vor dem Hintergrund integrierter Logistikketten immer bedeutsamer wird, gelangt die Perspektive der Beeinflussung des Wettbewerbs der Verkehrsträger untereinander mittels Allianzen ebenfalls in das Blickfeld der Untersuchung. Übergeordnetes Ziel der Arbeit stellt die Analyse des Allianzphänomens und die Systematisierung spezifischer Allianzmodelle im europäischen Eisenbahngüterverkehr vor dem Hintergrund der sich fortlaufend verändernden Marktstruktur und fortgesetzten Deregulierung dieser Branche dar. Das Hauptinteresse gilt der Allianzrelevanz in dieser Branche im allgemeinen und der Verdeutlichung branchenstrukturprägender Allianzmuster im besonderen. Betriebswirtschaftlicher Forschung in diesem Branchenumfeld soll damit ein stärkeres Gewicht beigemessen werden.

本論文主要是透過產業經濟學中的產業組織研究，運用J. S. Bain及F. M. Scherer 為首的市場結構－行為－績效(S-C-P)的分析方式，來探討中國大陸汽車產業市場結構、廠商行為與績效之間的關係。 運用產業組織S－C－P的分析方式來研究產業的發展及績效的關係已經相當普遍，從早期的E. Mason、J. Bain到W. Shepherd、F. M. Scherer以還，此領域的研究成果相當豐富，然而多集中在實施市場經濟的西方國家，對經濟轉型的國家如東歐、中國及蘇聯等則較為少見。 本論文研究的主要目的，即在探討大陸地區汽車產業之市場結構、產業特性、產業內廠商之營運行為及彼此間的競爭型態；並進一步運用現有的資料，以實證方法對汽車產業市場結構、廠商行為及利潤之來源加以檢定，再由實證中所發掘出的資訊，評估研判大陸汽車產業發展的走向及相關問題。由於中國大陸是一個在二十世紀八十年代開始才自計畫經濟體制逐漸轉型為市場經濟體制的國家，本身仍具有計畫經濟的一些特質，產業政策的制訂及強制實施，對大陸汽車產業結構及行為均具有一定的影響力，因此本文亦透過大陸官方頒布的汽車產業政策來探討其對汽車產業的影響。 經由本文對中國大陸汽車產業的分析顯示，產業組織中市場結構（S）、行為（C）與績效（P），彼此間是處於相互影響之動態關係。而實證研究亦顯示，市場結構及行為對廠商績效的產生有密切的關聯。 在市場結構方面，大陸汽車產業的市場結構有逐漸大型化、集團化的趨勢，大型企業的市場占有率也逐年提升，市場集中度（CR4、CR8）相對提高；唯有轎車生產廠商在進入業者增多及競爭激烈之下，市場集中度有下降的現象，未來大陸汽車產業整體的市場結構有進一步緊縮並向寡頭壟斷發展的趨勢。在廠商行為方面，廠商的併購重組及價格競爭行為有助於市場結構的改善，投資研發及行銷策略等廠商行為則與市場結構及績效有相互影響。另外大陸汽車產業政策對市場結構、行為、績效則有大小不一的影響，部分產業政策目標得以實現，部分政策目標則無法完成。 在汽車產業集中度與績效之直觀性分析方面，根據1995至2003年的相關數據顯示，不論是整車生產廠商、企業集團或轎車生產廠商，其市場集中度愈高，其績效表現相對較佳（工業增加值率愈高）。 另外從實證分析的結果來看，與市場結構相關的5個變數，其中市場集中度（H）、市場占有率（MS）與績效為正相關；而市占率平方（MS²）及勞動密度（Labor）為負相關，大致上與我們的假設相符。另外資本密度（Capital）的實證結果則與假設有所不同，其中34家車廠樣本的檢定為正，而15家集團的結果為負，顯示大陸汽車產業目前並不具資本優勢，尤其是部分汽車集團的資產對績效的產生並不具正面效益。在行為變數方面，投資行為（Investment）對績效的影響為正相關，與我們的假設相同，顯示持續的投資對汽車廠商績效的產生具有重大正面的影響。時間趨勢（Time）變數也有所不同，實證顯示34家車廠的績效隨時間趨勢有逐漸下降的情形，而汽車集團的績效則隨時間趨勢呈上升現象。 正如產業組織理論所述，廠商的績效可以有多個評定考核的標準，一般均以利潤最大化或搶占最大的市占率為目標，但以大陸目前汽車產業狀況而言，本土汽車企業或大陸官方控股的汽車集團能否開發出知名的自有汽車品牌應當是重要的績效之一。根據本文的研究也發現，中國大陸目前汽車集團或大型汽車企業的短期目標是做大規模，利用規模經濟及擴大市占率來鞏固利基。但卻忽略其基本目標或長期目標應是做強企業，所謂做強企業應是運用研發成果或提升經營效率使成本降低，以提高企業的利潤率或附加價值，才算是一個成功的企業。做大企業固然不易，做強企業更是困難，但唯有持續不斷地突破、創新、研發，才能在競爭激烈的中國汽車大戰中脫穎而出，立於不敗之地。 / This thesis aims to explore the relationship between market structure, firm conduct and performance of the automobile industry in mainland China by applying the structure-conduct-performance (S-C-P) model of industrial organization. There are many outstanding studies using S-C-P approach to examine the dynamics between industrial development and performance, such as E. Mason, J. Bain, W. Sherpherd, F.M. Schere, etc. However, most of them focus on the market economies in western countries. Few of them discuss the situations in Eastern Europe, China and former Soviet Union countries that undergo economic transitions. The thesis intends to explore the characteristics of the market structure, firm conduct and economic performance in China’s automobile industry, to examine the dynamics of S-C-P in automobile industry by regression analysis, and to evaluate the development and problems of the automobile industry in mainland China. Although China has been undergoing economic transitions from a planned economy to a market economy since 1980s, not all the characteristics of the planned economy are replaced. The regulatory policy making and implementation have significant impacts on its automobile market structure and firm conduct in this industry. In this regard, the thesis intends to discuss how China’s policy influences its automobile industry. Paramount findings of this research suggest that, in China’s automobile industry, market structure, firm conduct and performance interact with one another. Regression analyses indicate that market structure, firm conduct and performance are strong associated. The market structure of the automobile industry in China characterizes large firms and groups, the growing market share rate of large-scale enterprises on a yearly basis and the rise of market concentration degree (CR4, CR8). However, the value of market concentration degree of sedan manufacturers decreases due to the increase of competitors in this market. As a result, the market structure of China’s automobile industry will evolve to oligopoly in the future. Firm conducts such as merger, reorganization and price competition help to improve the market structure. Other firm behaviors like investment, R&D, and marketing strategies influence the market structure and performance and vice versa. Moreover, China’s automobile industrial policies have various impacts on market structure, firm conduct and performance. In practice, some goals of the automobile policies are attainable, however, others are unattainable in practice. Based on the data between 1995 and 2003, a statistical analysis of concentration degree and performance in automobile industry suggest a positive relationship that higher market concentration degree results in better performance (higher industrial added-value rate), regardless whole-car manufacturers, group enterprises or sedan manufacturers. The multiple regression analyses of five variables related to market structure represents that the values of concentration degree (H) and market share (MS) alike have positive effects on the value performance whereas the values of market share rate squared (MS²) and labor density(Labor) alike have negative effects on the value of performance. These results support our hypotheses in this study. Nevertheless, the result of a relationship test for capital density（Capital） and performance is different from our hypothesis. The value of capital density of 34 car firms and the value of performance have a positive relationship, which echoes our assumption. Yet the hypothesis test for capital density of 15 groups leads to the opposite. It suggests that: capital advantage does not emerge in China’s automobile industry so far. In particular, assets of some automobile groups do not have beneficial effects on business performance. Firm conduct includes one variables: investment. Regression analysis indicates a positive relationship between investment and performance. The result is consistent with our hypothesis and concludes: constant investment contributes to automobile firm performance. Relationship testing for time and performance shows that: when the value of time increases, the value of 34 automobile firms’ performance decreases whereas the value of 15 groups’ performance increases, accordingly. The theory of Industrial organization provides multiple criteria to assess firm performance which usually aims to maximize profit or market share. In the case of current automobile industry in China, whether or not local automobile firms or state-owned enterprises achieve a successful brand building of China-made vehicles should be an important indicator of performance. This research also discovers that on one hand the automobile groups and large-scale enterprises in China embrace short-term goals to maximize firm scale and market shares so as to maximize revenues by exploiting the advantages of economy of scale, however, on the other hand, they ignore fundamental, long-term goals to be sustainable, successful and competitive corporations that invest R&D to increase business efficiency, reduce costs, and boost marginal revenue and added-value rate. Being a big firm is never easy yet being a competitive enterprise is even more difficult. Only with constant improvement in management, investment in R&D, the invention of production can an enterprise survive and succeed in the competition in China’s automobile market.
