多國籍企業之最適汙染稅 / The Optimal Taxation on Pollution under Multinational Enterprise

余斯婷, Yu, Shih Ting Unknown Date (has links)
本文以 Barnett (1980) 一文為基礎,採用第三地市場以納入廠商型態為多國籍企業 (multinational enterprise) 的模型。本文旨在分析當兩國政府面對獨占廠商的生產不效率及製造過程中汙染排放引發的生產外部性時,如何制定最適汙染稅稅率。並比較經濟開放後資本要素可自由於兩國間移動,最適汙染稅稅率會如何變化。 本研究發現政府課稅將受三種效果影響:消費者剩餘效果 (consumer surplus effect)、利潤移轉效果 (profit-shifting effect)、汙染控制效果 (pollution control effect)。不論在封閉經濟體系或開放經濟體系下,當消費者剩餘效果大於利潤移轉效果時,政府會將最適汙染稅率制定低於皮古稅 (Pigouvian tax),以補貼獨占廠商增加產量以提高社會福利;若利潤移轉效果大於消費者剩餘效果時,最適汙染稅稅率將高於皮古稅,以藉由汙染稅獲取更多的企業利潤。 當經濟開放後資本可於兩國間自由移動,除原先稅率對產量的直接效果(direct effect) 外,稅率亦會透過資本間接影響產量,為間接效果 (indirect effect)。間接效果將使產量對於稅率的變動較不敏感,因此為吸引具流動性的資本要素進入當地投資,政府會將汙染稅稅率調高以獲取更多企業利潤。 / Based on the setting of Barnett (1980), the thesis develops a model to analyze the optimal pollution tax on multinational enterprises with negative externalities. Governments have only one policy variable: the pollution tax. Each government levies the pollution tax on the output of multinational enterprises, and the tax revenues are returned to the residents in a lump sum manner. The purpose of this thesis is to explore the optimal taxation on the multinational enterprise with externalities and mobile capital flow. The thesis obtains several results: First, no matter in the case of closed economy or open economy, the second-best optimal pollution tax may be less or greater than the marginal pollution damage. It may be lower because the consumer surplus effect dominates the profit-shifting effect, so the government chooses a lower tax rate to stimulate production and to increase social welfare. Second, when the capital can freely move between countries, the governments will levy a tax rate higher than that of a closed economy. Doing so can attract the flow of capital so that government can get more profit.

Le transport ferroviaire régional de voyageurs en France : à la lumière de la théorie néo-institutionnaliste et des comptes de surplus / The regional rail travel in France : in the light of the new institutional theory and surplus accounts

Desmaris, Christian 02 April 2010 (has links)
Cette thèse, qui s’inscrit dans le questionnement économique général sur la recherche d’outils de régulation des industries de réseaux, questionne la pertinence du choix français de régionalisation ferroviaire. Ce dernier, depuis la réforme introduite par la loi SRU, associe le maintien du monopole d'exploitation de la SNCF pour le Transport Express Régional (TER) avec la décentralisation aux Régions d'une prérogative jusqu'alors assurée de manière bureaucratique et centralisée. Dans cet environnement institutionnel, original au regard du mouvement européen, les Régions françaises ont-elles réussi à écrire et à gouverner le "système SNCF-TER" ?Pour répondre à cette double interrogation, l’auteur mobilise la théorie néo-institutionnelle, à partir de laquelle il propose une matrice interprétative de l’architecture économique des conventions TER et présente une transposition de la méthode des comptes de surplus (MCS), pour l’étude de la performance économique de ces contrats.Les résultats obtenus, sur l’échantillon des sept régions qui ont expérimenté la régionalisation, ne confirment que partiellement les déductions habituelles obtenues à partir de la théorie standard du monopole et de la capture du réglementateur par la firme régulée. Si la contractualisation SNCF / Régions, très éloignée du modèle « net cost » (présent dans de nombreux pays en Europe), exprime l’acceptation par le Législateur d’une large couverture des risques industriels, commerciaux, et plus encore sur investissements, par la Collectivité, la régionalisation s’est traduite par une grande diversité contractuelle. Une analyse fine montre le caractère hybride des modes de gouvernance que l’auteur qualifie de « fiduciaro-autoritaires ». La MCS révèle que si l’effet du monopole est bien présent et s’impose aux Régions, il ne profite guère à la SNCF, mais plutôt à RFF. Tendanciellement, les voyageurs sont devenus « gagnants » de la régionalisation ferroviaire. / This thesis, which fits the general economical issues on the research tools of the network industries regulation, questions the relevancy of the French railways regionalisation. The latter, since the reform introduced by the law SRU associates the maintenance of the railway service operating monopoly for the Regional Express Transport (TER) with the decentralisation to the regions, so that they benefit from a prerogative ensured hitherto in a centralised and bureaucratic way. In this institutional environment, original compared to the European movement, have the French regions managed to write and to govern the "SNCF-TER system” ?To answer both questions, the author used the neo-institutional theory from which he offers an interpretative array on the economical structure of the TER conventions and presents a transposition of this method on surplus accounts to study the economical performance of these contracts.From a panel of seven regions which have tested the regionalisation, the results can only partially confirm the usual deductions made from the standard theory of the monopoly and the capture of the regulator by the regulated firm. If the contracting SNCF/Regions, far from the “net cost” model, expresses that the legislature accepts a broad industrial and commercial insurance cover, and more on investments made by the community, then regionalisation resulted in a larger variety of employment contracts.A detailed analysis shows the hybrid character of the governance methods which the author calls “fiduciaro-authoritarian”. The method on surplus accounts reveals that, while the effect of monopoly is present and essential to the regions, then it means little benefit to the railway operator but much to RFF. Today travellers have trendily become the “winners’ of the rail regionalisation.

'New departures' in infrastructure provision : an ongoing evolution away from physical assets to user needs

Ansar, Atif January 2010 (has links)
Infrastructure—communications, energy, transport, waste, and water networks—is critical for economic activity and social well-being. Practitioners, politicians, and economists advocate high levels of investment in infrastructure under the rubric of 'planning for growth' (or the 'push' paradigm). This paradigm relies on complex public-private arrangements in the name of public interest. These seemingly reasonable arrangements are, however, not delivering their promise. Evidence shows that the needs of infrastructure users in rich and poor countries are not being met, many private providers of infrastructure earn rich returns, assets are rarely built in time or on budget, and there is tremendous waste in the operation of many infrastructure industries. No other sector could survive the profligacy and slack common in infrastructure. I distil the following primary propositions of the accepted wisdom, which is inspired by mainstream economics: First, infrastructure assets necessarily entail high sunk costs and large economies of scale. Consequently, assets last for very long periods of time, and they cannot be readily moved. Second, infrastructure outputs are homogeneous. Third, one network fits all users (large and small). Fourth, infrastructure users, even large ones, are likely to have weak bargaining power in procurement of infrastructure outputs. I challenge these four propositions of the conventional wisdom by putting forward alternative hypotheses. First, instead of being monolithic and costly, infrastructures can be assembled (and disassembled) as flexible modules for specific users in specific places. Drawing on option pricing theory in quantitative finance, I recast infrastructures as 'portfolios of real options'. Second, infrastructure outputs are, in fact, heterogeneous and differentiated services. Third, one infrastructure network cannot fit all users, either today or in the future. Users are remarkably heterogeneous, not only in terms of unique user preferences but also in terms of spatial location. Infrastructure networks need to evolve in tandem with user needs or risk spatial, temporal, and relational obsolescence. Finally, users, large and small, are adept at exerting strong bargaining power in procuring infrastructure both prior to and after rendering durable and immobile investments. Users also strategically deploy intermediaries, e.g. futures and Over-the-Counter (OTC) exchanges, and real estate developers, to negotiate private contracts for infrastructure services. These findings are supported by two case studies. The first case study details the process by which ThyssenKrupp, a large steel company, bargained for its infrastructure by locating to a manufacturing site in the U.S. The second case study focuses on residents of Lavasa, one of the largest property developments in India. Here, small users of infrastructure exert strong bargaining power with the aid of intermediaries—the real estate developer and the property asset manager. New departures in infrastructure provision are urgently needed at a practical level. Poor investments rendered today—particularly if costly, inflexible, and durable—will suffocate tomorrow’s possibilities. The spatial, temporal, and relational approach proposed in this dissertation begins to offer an alternative account of how tomorrow can be modularly shaped.

La notion de fonctionnalité en droit canadien : quels fondements pour quels usages?

Jonnaert, Caroline 01 1900 (has links)
Ce mémoire analyse la notion de fonctionnalité. D'origine jurisprudentielle, ce concept tend à maintenir la dichotomie traditionnelle entre le régime des marques de commerce et celui des brevets. À la lecture des jugements rendus en la matière, le maintien d'une telle dichotomie empêcherait notamment de prolonger indûment un monopole échu sous le régime des brevets par l'enregistrement d'une marque de commerce. Cette étude tente de mieux cerner le concept de fonctionnalité et, plus précisément, de justifier son existence. Pour ce faire, une étude approfondie des régimes des marques de commerce et des brevets, nous permet de comprendre que chacun de ces corps de règles répond à une logique différente. Les fonctions des marques de commerce et des brevets sont en effet distinctes et aucun chevauchement ne semble être permis. Cette situation est d'ailleurs propre à ces régimes spécifiques. Un examen de l'étendue de la notion de fonctionnalité nous permet de constater que d'autres droits de propriété intellectuelle peuvent coexister. À titre d'exemple, nous croyons qu'une intersection est possible entre les régimes des dessins industriels et des marques de commerce. À l'issue de ces recherches, nous constatons que la notion de fonctionnalité est un principe jurisprudentiel bien établi en droit canadien visant à empêcher tout renouvellement à perpétuité d'un brevet par le biais du droit des marques de commerce. L'existence de ce principe nous semble être justifiée en matière de marques de commerce et de brevets. Cette conclusion pourrait toutefois différer dans le cadre d'autres droits de propriété intellectuelle, les fonctions de ces autres régimes semblant permettre des chevauchements. / This memory analyzes the notion of functionality. Of case law origin, this concept tends to maintain the traditional dichotomy between trademarks and patents regimes. In light of judgments rendered on that matter, the preservation of such dichotomy would notably prevent from illegally prolonging a monopoly fallen under the regime of patents by the registration of a trademark. This study tries to understand the concept of functionality and, more specifically, to justify its existence. In order to reach this goal, a detailed study of the regimes of trademarks and patents lead us to conclude that each of these bodies of rules answers to a different logic. Indeed, the functions of trademarks and patents are different and no overlapping seems to be allowed. This situation is particular to these two specific regimes. An examination of the area of the notion of functionality leads us to notice that other rights of intellectual property can coexist. For example, we believe that an intersection is possible between the regimes of industrial designs and trademarks. As a conclusion, we notice that the notion of functionality is a well established principle in Canada which tends to prevent any perpetual renewal of a patent under the trademarks regime. We believe that the existence of this concept is justified under trademarks and patents laws. However, this conclusion could differ within the framework of the other intellectual property rights, since these other rights' functions seem to allow an intersection between them.

S'établir et travailler chez l'autre : les hommes de la Compagnie royale d'Afrique au XVIIIe siècle / Being established and working in the other's home : the men of the French Royal African Company in the 18th century

Lopez, Olivier 10 June 2016 (has links)
Créée en 1741, la Compagnie royale d’Afrique succède à des compagnies à privilèges qui n’ont connu à Marseille, deux siècles durant, que des déboires dans leurs relations avec les Régences de Barbarie. Or, pendant plus d’un demi-siècle cette nouvelle structure commerciale connaît un réel succès. Avec des représentants installés de manière pérenne essentiellement dans la Régence d’Alger – comptoirs à La Calle, Bône et Collo – elle organise et contrôle dans les eaux barbaresques, comme le fit la première Compagnie du corail au XVIe siècle, la pêche de ce produit apprécié sur la rive nord de la Méditerranée. Cependant, elle a pour tâche première d’assurer la traite des blés afin de participer au bon ravitaillement du royaume, tout en intervenant également sur d’autres marchés. À l’heure où la Méditerranée devient un espace périphérique du commerce mondial, où la pensée économique remet en cause les monopoles commerciaux et où les relations avec les Régences barbaresques tendent à se normaliser, cette Compagnie constitue un bon observatoire pour suivre les pratiques commerciales du second XVIIIe siècle et décrypter les stratégies des hommes qui en ont la direction. Par ailleurs, s’établir et travailler chez l’Autre, avec ses avantages et ses contraintes, invite également à saisir les relations à l’altérité. Aussi, au-delà de l’étude des flux, des routes maritimes, de l’outillage nautique, des produits, des marchés et des hommes – dirigeants ou simples exécutants –, cette recherche, qui mêle les approches quantitative et qualitative, se présente également comme une lecture des pratiques interculturelles entre les différents acteurs des deux rives de la Méditerranée. / Founded in 1741, the French Royal African Company succeeds to exclusive trading companies, which only suffered setbacks in Marseille for two centuries in their relations with the Regencies of Barbary. Yet, for more than half a century, this new commercial structure experienced a real success. With officials durably settled primarily in the Alger Regency – trading stations in El Kala, Annaba and Collo –, the Royal African Company organizes and controls the fishery of coral in the Barbarian maritime territories, just like the first Coral Company did in the 16th century; the coral being a cherished product on the north shore of the Mediterranean Sea. However, the primary task of the Royal African Company is to ensure the trading of wheat in order to contribute to supplying the Kingdom of France and intervene as well on other markets. At the time when the Mediterranean becomes a peripheral area of world trade, when the economic thought calls into question the trading monopolies and when the Barbarian Regencies tend to normalize, this Company represents a good observatory to follow the commercial practices of the second half of the 18th century and analyze the strategies of the leading men. Besides, being established and working in the Other’s home, with its advantages and constraints, invites to understanding the relation to otherness. Thus, beyond the study of flows, sea lanes, nautical equipment, products, markets, and men – be it leaders or simple performers –, this research, blending quantitative and qualitative approaches, can also be presented as a reading of the intercultural practices between the various players on both sides of the Mediterranean.

Tarifas de distribuição de energia elétrica no Brasil: aperfeiçoamento da metodologia tarifária a partir de parâmetros de continuidade do serviço, sustentabilidade econômico-financeira e simplicidade regulatória. / Electricity distribution tariffs in Brasil: improving regulatory methods from quality of service and economic-financial sustainability regulation.

Brito, Erico Henrique Garcia de 03 February 2017 (has links)
A partir de revisão do histórico da regulação do segmento de distribuição de energia elétrica no Brasil, da revisão de conceitos de Teoria da Regulação, Distribuição de Energia Elétrica, Estrutura Tarifária, Regulação de Monopólios Naturais, Qualidade do Serviço Prestado, e Sustentabilidade Econômico-Financeira, assim como definições de Direito Administrativo, Teoria Geral de Concessões de Serviços Públicos e política de preço aplicada a monopólios naturais, aprende-se que o regime tarifário chamado de serviço pelo preço (price cap) foi adotado a partir da edição da Lei de Concessões, sendo abandonado o regime do custo do serviço (rate of return), praticado desde a década de 1950. Contudo, a distinção entre os dois regimes de regulação tarifária fica prejudicada devido às práticas do regulador, fato que ocorre não apenas no Brasil. Conforme estabelecem os contratos de concessão, as tarifas deveriam ser preservadas pela equação de equilíbrio inicial \'RPI +/- X\', sendo previstas revisões tarifárias periódicas, observadas as alterações na estrutura de custos e de mercado, os níveis de tarifas observados em empresas similares no contexto nacional e internacional, e estímulos ao ganho de eficiência e à modicidade tarifária. Passadas duas décadas da implantação do price cap, observa-se que o regulador incorporou práticas do rate of return, criando instrumentos de reposicionamento das tarifas de acordo com critérios e trajetórias de custos operacionais eficientes e componentes discricionários de cálculo do ganho de produtividade, dotando o processo de reajuste e revisão das tarifas de excessiva complexidade. Assim, buscando-se maior simplicidade e clareza nos processos tarifários, de modo a incentivar de forma mais adequada o investimento na melhoria da qualidade do serviço e na sustentabilidade da concessão, o presente trabalho propõe aperfeiçoamentos na metodologia tarifária com base em parâmetros de eficiência em relação à qualidade do serviço prestado, discutido no âmbito do Mecanismo de Incentivo à Melhoria da Qualidade (MIQ) por meio do componente \'Q\' do Fator X, e de eficiência em relação à gestão econômico-financeira (sustentabilidade), aferida por parâmetros utilizados amplamente no setor financeiro, tratados como elementos de uma política de incentivos para assegurar a trajetória de sustentabilidade da concessão. A partir do princípio contratual de que os processos tarifários consideram como receita da distribuidora a soma de uma parcela não gerenciável (VPA) e de parcela gerenciável (VPB), a busca por maior simplicidade e clareza diz respeito ao estrito cumprimento dos critérios contratuais, com retorno à prática da regulação de serviço pelo preço, como estabelecido pela Lei de Concessões. A aplicação dos aperfeiçoamentos propostos é realizada mediante estudos de caso de duas distribuidoras de energia elétrica em situações de qualidade e sustentabilidade distintas. O resultado ilustra que a qualidade e sustentabilidade do serviço podem ser parâmetros importantes para introdução de uma metodologia menos complexa e mais objetiva para reajuste e revisão das tarifas de fornecimento no Brasil. / The Tariff Regulation for public service distribution of electrical energy, called \"price cap\" was adopted in Brazil from the publication of Law 8.095/1995 (the Law of Concessions), therefore abandoning the \"return rate\" remuneration system practiced since the late 1950s. However, the distinction between price cap and return rate regulation was negatively affected due to practices of the regulatory agency (National Electric Energy Agency - ANEEL), which occurs not only in Brazil. As established in concession contracts, the tariffs should be preserved by the equation of initial balance \'RPI +/- X\', forecasting tariff reviews periodically by observing changes in the structure of the licensee\'s costs and market share, the levels of rates observed in similar businesses in the national and international context, as well as stimulating efficiency gains and controlling tariffs. After two decades of implementation of the system of price cap in Brazil, and after four cycles of periodic review of tariffs, it is observed that the regulator has incorporated practices of rate of return throughout the process, creating instruments of repositioning of tariffs in accordance with criteria of operational costs considered efficient and discretionary components of calculating the productivity gains (X Factor), giving the process of readjustment and revision of rates of excessive complexity. In search of greater simplicity and clarity in the tariff process in order to encourage more adequately the investment in improving the quality of service and sustainability, this Thesis presents proposals for the improvement of tariff methodology based on parameters efficiency in terms of quality of service, objectively measured by global indicators of continuity and efficiency in relation to the economic and financial management (sustainability), measured by parameters used widely in the financial sector. The improvement of the efficiency of quality is discussed under the Incentive to Quality Improvement Mechanism (MIQ) of the Brazilian tariff regulation through the \'Q\' component of Factor X. The improvements on the extent of economic and financial sustainability are treated as elements of an incentive policy to ensure a path of sustainability of the concession, given that the Brazilian regulator has not adopted explicit mechanisms of sustainability, except those specifically defined in the process of renewal of distribution concessions, pursuant to Presidential Decree n. 8.461/2015. From the contractual principle that tariff processes consider the distribution company Requested Revenue as the sum of an unmanageable portion (VPA) and manageable portion (VPB), the search for greater simplicity and clarity with respect the strict compliance with the contract criteria, returning to the practice of price cap regulation, as established by the Concessions Law. The implementation of improvements for the proposed tariff mechanisms is carried out through case studies relating to two electricity distribution companies in different quality and sustainability situations. The result of the study shows that the quality and sustainability of the service in the electricity distribution segment can be important parameters for introducing a less complex and more objective methodology for adjustment and review of electricity tariffs in Brazil.

Framtidens officer, härförare eller bokmal? : En studie av den svenske officeren och en analys av examensmålen för Officersprogrammet på Försvarshögskolan

Cattelin, Jonas, Kinander, Mats January 2019 (has links)
Utbildningen av officerare är omdiskuterad och har kanske alltid varit det. Men de senaste årens förändringar av officersutbildningen och akademisering av yrket samt ändrade befälsstrukturer i Försvarsmakten (FM) har återigen satt fart på diskussionen. Det handlar bland annat om FM får den officer som man behöver för att kunna bygga starka krigsförband och om officeren har de kvalifikationer som detta kräver? Men vad är officersyrket för något och vad är det egentligen FM vill ha? Studien undersöker just det, vad en officer är och vilka egenskaper som en officer förväntas att ha med sig in i yrket.  Utbildningen vid Försvarshögskolan (FHS) Officersprogrammet (OP) är det som skall leda till en officer med rätt kvalifikationer och egenskaper vilket leder till den andra delen av studien, där bilden av vad en officer är jämförs med de examensmål som programmet har. Dessa examensmål framgår av förordningen för FHS och med de 17 examensmålen examinerade så skall kadetten vara klar att påbörja sitt yrke som officer. Frågan är om den förutsättningen verkligen finns?   För att kunna göra denna jämförelse har studien, genom intervjuer, tagit fram en modell av en officer från det unika med officersprofessionen, våldsmonopolet, via antagningskrav för utbildningen till egenskaper som officeren måste ha och roller som officeren utövar. Modellen har två portalparagrafer som är att betrakta som en sammanställning, vilka studien anser är nödvändiga för att hantera de mest allvarliga frågor som i förlängningen kan innebära beslut om liv eller död.  Portalparagraferna är mångsidighet och en väl utvecklad inre kompass.   I jämförelsen mellan modellen och examensmålen har studien funnit att examensmålen är avmilitariserade och har en teoretisk slagsida. Den väpnande striden har kommit i skymundan och officerares ansvar för det statliga våldsmonopolet inte finnsmed. De tydliggör inte heller en del av de egenskaper och kvalifikationer, som studien har visat, är nödvändiga för att officeren som ledare ska kunna hantera yrkesprofessionen och axla det ansvar detta kräver. Det gör att kadetten inte fullt ut får den möjlighet att bli den officer som FM behöver.   Studien visar bland annat att examensmålen bör ses över och kanske även till del skrivas om. / The training of military officers is well debated and has always been. But the recent years' changes in officer training and the academisation of the profession and also changed command structures in the Swedish Armed Forces (SAF) have once again set the stage for discussion. Among other things, it is about SAF getting the officer they need to build strong units and whether the officer has the qualifications that this requires? But what is the profession as an officer and what does the SAF really wants? The study examines just that, what is a military officer and what qualities an officer is expected to bring into the profession.  The education at the Swedish National Defense University (SDU) and the military officers’ program (OP) is the education, which should lead to a profession as an officer with the right qualifications and characteristics. This leads to the second part of the study, where the image of an officer is compared to the exam objectives for the program. These exam objectives are stated in the ordinance for SDU, and with the 17 exam objectives examined; the cadet should be ready to begin his profession as an officer. The question is whether this condition really exists?  In order to make this comparison, the study, through interviews, has developed a model of an officer from the unique with the profession, the monopoly of violence, via admission requirements for the education, to characteristics that the officer must have and roles that the officer exercises. The model has two portal paragraphs that are a compilation of the model, which the study considers necessary to deal with the most serious issues that may ultimately involve decisions on life or death.   The portal paragraphs are versatility and a well-developed inner moral guidance.  In the comparison between the model and the exam objectives, the study found that the objectives are demilitarized and have a theoretical approach. The armed battle is overshadowed and the officers' responsibility for the state monopoly of violence is not included. Nor do they clarify some of the characteristics and qualifications that the study has shown are necessary for the officer to be able to manage the profession as a leader and shoulder the responsibility this requires. This means that the cadet does not fully get the opportunity to become the officer that SAF needs.  The study shows, among other things, that the exam objectives should be reviewed and perhaps even partly rewritten.

Three Essays in Market Design

Frys, Lucien 30 August 2018 (has links)
Diese Arbeit besteht aus drei unabhängigen Kapiteln. Jedes von ihnen untersucht, wie die Gestaltung von Allokationsregeln das Ergebnis eines Marktes beeinflussen kann. Das erste Kapitel untersucht die Folgen der Beschränkung der Mechanismen, die einem Monopsonisten zur Verfügung stehen, auf Mechanismen, die allen Verkäufern den selben Preis anbietet. Ich zeige, dass dies Beschränkung nicht immer verhindert, dass er Informationen der Verkäufer extrahiert und den Preis damit anpasst. Das zweite Kapitel befasst sich mit der Verteilung von Studentenwohnheimplätzen. Die Studenten dürfen eigene Präferenzen bezüglich eines Wohnheimplatzes sowie zur Zuteilung ihrer Freunde angeben. Ich zeige, dass der random serial dictatorship modifiziert werden kann, um diese neuen Präferenzen zu ermöglichen. Die beiden vorgeschlagenen Lösungen haben schwache Anreizeigenschaften, wenn die Studierenden kooperieren können. Ich zeige jedoch, dass dieses Problem für den ersten Lösungsvorschlag verschwindet, wenn der Markt groß und wettbewerbsfähig ist. Schließlich wird im letzten Kapitel untersucht, wie die Gestaltung von Aufnahmeprüfungen an Universitäten die Zusammensetzung von Gymnasien und Universitäten beeinflussen kann. Das Kapitel vergleicht zwei Aufnahmeprüfungen. In der ersten, werden die besten Schüler jedes Gymnasiums ausgewählt, während in der anderen die insgesamt besten Studenten ausgewählt werden. Wenn der Test verrauscht ist oder wenn die Peer-Effekte für die guten Schüler niedrig sind, schickt der erst Test bessere Studenten in der Universität und fordert Vielfalt in Gymnasien. / The three chapters of this thesis are independent. Each of them investigates how the design of allocation rules may shape the outcome of a market. The first chapter studies the consequences of restricting the mechanisms available to a monopsonist to uniform price posting mechanisms. I show that it doesn't always prevent him to extract meaningful information from the sellers before posting the price. I also show that conditioning this offer on the transaction achieving a minimal quantity facilitates this task. Finally, I address the welfare and the implementation issues and apply the results to takeover operations. The second chapter studies the allocation of houses to students, when students have preferences over the houses they receive and over their friends' allocation. I show that the random serial dictatorship can be modified to accommodate this new set-up. The two solutions proposed have weak incentive properties if students can cooperate. However, I show that this problem disappears for one of them if the market is large and competitive. Finally, the last chapter studies how the design of entrance university exams can be used to influence the composition of high schools and universities. It shows that if the test is noisy or if the peer effects for the good students are low, giving the university's slots to the best students of each high school selects better students than giving them to the best students overall and desegregates high schools.

Arquitetura na era digital-financeira: desenho, canteiro e renda da forma / Architecture in the financial-digital era: the design, construction, and rent of form

Arantes, Pedro Fiori 20 April 2010 (has links)
A arquitetura contemporânea vive hoje uma arriscada fusão com a publicidade e a indústria do entretenimento. Tal convergência exige uma expansão da forma arquitetônica até o limite de sua materialidade. Em busca da renda informacional máxima, característica do universo das marcas mundiais, constatamos uma inversão de seus antigos fundamentos construtivos e produtivos, subvertidos por um jogo de volumes e efeitos para além de qualquer regra ou limitação. Aliado às técnicas digitais de projeto e à reorganização dos canteiros de obra, esse novo fetichismo da forma, análogo à autonomização do poder e da riqueza abstrata no capitalismo contemporâneo, define a nova condição da arquitetura. Estudaremos essa condição tomando como fio condutor projetos dos arquitetos mais consagrados pelo atual sistema de distinção e premiação. No propósito de melhor identificar esta arquitetura da exceção, investigamos nas obras emblemáticas dos últimos vinte anos um conjunto de particularidades e recorrências, que a nosso ver define a economia política da exceção e da regra no mundo atual. Principiamos pela análise do emaranhado de significados que sustentam hoje a forma construída, passando em seguida à esfera da produção das novas modalidades de projeto digital às transformações no canteiro de obras para, ao fim, examinar como ocorrem a circulação (com a proliferação de imagens midiáticas), o consumo (especialmente por meio da indústria do turismo) e a distribuição de riquezas que essa arquitetura favorece. O que se verifica é uma produção sobredeterminada pela busca da renda monopolista derivada das propriedades intrínsecas da forma, em seu novo estágio de concepção e realização. Esperamos, assim, mostrar como a arquitetura de ponta tornou-se uma das manifestações mais expressivas da acumulação flexível e da renda das marcas sob a dominância da lógica das finanças. / Contemporary architecture is dangerously enmeshed with the entertainment industry and the field of advertising. This meshing has pushed architectural form to the limits of materiality. Architecture today searches for maximum informational rent, a process typical of global product branding; through this process, established building and production principles are subverted by a play of volumes and effects beyond any rule or limitation. Relying on digital design technologies and the reorganization of the building site, this new fetishism of form, analogous to the autonomization of power and abstract wealth in contemporary capitalism, defines the new condition of architecture. We study this condition by focusing on the work of those architects who are most successful in the current system of professional recognition and rewards. So as to identify this architecture of exception more precisely, we analyze emblematic works from the last twenty years; in these works we identify a set of particularities and recurrent issues that define the political economy of exception and rule today. We begin by analyzing the tangle of meanings associated with contemporary built form. We then move on to the sphere of production from the new technologies of digital design to transformations in the building site. Finally, we examine three processes as they relate to contemporary architecture: circulation (through the proliferation of images in the media), consumption (in particular through the tourist industry), and distribution of wealth. Our investigation reveals that architectural production, in its new stage of conception and realization, is overdetermined by the search for monopoly rent through intrinsic properties of form. We argue that cutting-edge architecture has become one of the most expressive manifestations of flexible accumulation and brand revenue under the prevailing logic of financial capitalism.

La distribution officinale du médicament à l'épreuve de l'européanisation et de la globalisation : une étude au travers de trois exemples : la France, l'Angleterre et l'Italie / Retail pharmacy drug distribution contending with europeanisation and globalisation

Amouric, Jane 08 January 2016 (has links)
L'influence européenne, notamment politique et juridique, la globalisation des échanges de médicaments de même que les conséquences de la globalisation - des crises sanitaires, économiques, financières - affectent les modalités d'organisation et d'exercice de la pharmacie d'officine française, italienne et anglaise. La convergence étant généralement présentée comme figurant au titre des conséquences possibles de l'européanisation et de la globalisation, les régimes français, italien et anglais de distribution de médicament à l'officine évoluent-ils vers une forme de « modèle juridique » commun, dépassant leur opposition historique ? En réalité, non seulement l'on assiste à l'émergence de modèles juridiques d'organisation et d'exercice de la pharmacie qui ne sont pas porteurs d'une unité susceptible de réduire de manière significative les différences entre les législations nationales, mais encore, cette unité n'est pas opportune. En effet, le maintien de spécificités nationales ainsi que l'adaptation des réglementations aux contextes nationaux apparaissent comme des éléments garants de l'efficacité des régimes nationaux de distribution officinale des médicaments. Pour autant, l'efficacité des réglementations ne se résume pas à la garantie des spécificités nationales de l'encadrement du secteur, comme l'illustrent les obstacles à la réparation des dommages imputables aux médicaments et à la protection du monopole pharmaceutique. Si certains apparaissent justement liés aux caractéristiques nationales, d'autres concernent de manière spécifique la lutte contre les ventes illégales de médicaments / European influence, especially political and legal, the globalisation of drug trade as well as the consequences of the globalisation of health, economic and financial crises impact the organisation and practice of French, Italian and English retail pharmacy. Convergence is generally presented as one of the possible consequences of europeanisation and globalisation. In effect, are the legal regimes of drug distribution in retail pharmacies in France, Italy and England evolving towards a common « legal model », beyond their historical opposition ? In reality, not only are we witnessing the emergence of organisational and operational retail pharmacy legal models that do not carry a unicity that would enable significantly reducing differences between national legislations, but this unicity would not be timely. Indeed, the preservation of national specificities, as well as the adaptation of regulations to national contexts appear as key guarantors of the efficacy of retail pharmacy drug distribution national legal regimes. However, the efficacy of regulations cannot be summarised to guaranteeing the sector’s national specificities, as illustrated by the obstacles to compensation for damages attributable to medicines and to the protection of the pharmaceutical monopoly. While some of these obstacles appear precisely linked to national characteristics, others relate specifically to the war against illegal drug sales
