Dans le cadre de la Western Climate Iniative, le Québec a déployé en 2012, un système de plafonnement et d’échange de droits d’émission de gaz à effet de serre (SPEDE). Il s’agit de l’un des premiers régimes de ce type en Amérique du Nord et celui-ci pourrait à terme, constituer l'un des maillons d’un marché commun du carbone à l’échelle du continent. Toutefois, le SPEDE appartient à une catégorie d’instruments économiques de protection de l’environnement encore peu connue des juristes. Il s’inscrit en effet dans la régulation économique de l’environnement et repose sur des notions tirées de la théorie économique, dont la rareté, la propriété et le marché. La thèse s’insère donc dans le dialogue entre juristes et économistes autour de la conception et de la mise en œuvre de ce type d’instrument. Afin d’explorer son architecture et de révéler les enjeux juridiques qui le traversent, nous avons eu recours à la méthode de l’analyse économique du droit. Celle-ci permet notamment de montrer les dynamiques d'incitation et d’efficacité qui sont à l'œuvre dans les règles qui encadrent le SPEDE. Elle permet également à donner un aperçu du rôle décisif joué par la formulation des règles de droit dans l’opérationnalisation des hypothèses économiques sous-jacentes à cette catégorie d’instrument. L’exploration est menée par l’entremise d’une modélisation progressive de l’échange de droits d’émission qui prend en compte les coûts de transaction. Le modèle proposé dans la thèse met ainsi en lumière, de manière générale, les points de friction qui sont susceptibles de survenir aux différentes étapes de l'échange de droits d'émission et qui peuvent faire obstacle à son efficacité économique. L’application du modèle aux règles du SPEDE a permis de contribuer à l’avancement des connaissances en donnant aux juristes un outil permettant de donner une cohérence et une intelligibilité à l’analyse des règles de l’échange. Elle a ainsi fourni une nomenclature des règles encadrant l’échange de droits d’émission. Cette nomenclature fait ressortir les stratégies de diversification de l’échange, d’institutionnalisation de ses modalités ainsi que les enjeux de la surveillance des marchés, dont celui des instruments dérivés adossés aux droits d’émission, dans un contexte de fragmentation des autorités de tutelle.

Esta monografía pretende evaluar los efectos de la tradición exportadora minera y el TLC entre China y Chile desde las perspectivas de violencia estructural y desarrollo como libertad de Amartya Sen y Johan Galtung, respectivamente. A través del análisis de algunos procesos históricos que han configurado las actuales dinámicas mineras y comerciales en Chile, y de las libertades reales que poseían los chilenos antes y después de la entrada en vigor del acuerdo, se logra comprender la manera en la que los fenómenos estudiados logran constreñir o impulsar el desarrollo de las capacidades de los chilenos para llevar a cabo las vidas que desean.

El comercio internacional y los flujos de inversión se han incrementado en las últimas décadas más rápidamente que el producto interno bruto mundial. Este rápido crecimiento de las transacciones internacionales se conoce comúnmente como globalización. Este fenómeno puede ser visto como un dinamizador del crecimiento y desarrollo, en la medida en que los países tiendan a especializarse en la producción de aquellos bienes en los que tienen ventaja comparativa. Otros, por el contrario, argumentan que la globalización no ha contribuido al crecimiento mundial de manera homogénea, beneficiando solo a un número pequeño de paí- ses y dando lugar a la concentración de los flujos de comercio e inversión y a grandes inequidades. La evidencia muestra, sin embargo, que los efectos de la globalización en los países en desarrollo dependen de diversos factores, especialmente de las características de los países y de las regiones. Las ganancias en bienestar se deben más a las medidas de liberalización implementadas por los países, que a las concesiones de comercio otorgadas por los socios comerciales. Así mismo, la marginalización de algunos países de los mercados mundiales no es inherente al proceso de globalización. Esta se puede explicar más que todo por el tipo de polí- ticas domesticas implementadas por estos países. Algunos países en desarrollo han sido bastante exitosos en la implementación de una estrategia de desarrollo basada en la IED. En estos casos, las inversiones se han asociado con la rápida industrialización y una concomitante expansión de las exportaciones con alto valor tecnológico.

La Organización Mundial del Comercio (OMC) ha fortalecido y mejorado el sistema multilateral de comercio, surgido en los años siguientes al final de la Segunda Guerra Mundial, con el fin de garantizar la libre competencia entre los países miembros, eliminar las barreras al comercio internacional y permitir cada vez más el acceso de las empresas y de los consumidores a los mercados extranjeros de bienes y servicios.

Drawing on discussions within a CEPS Task Force on the revised EU emissions trading system, this report provides a comprehensive assessment of the pros and cons of the various measures put forward by different stakeholders to address the level and stability of the price of carbon in the EU. It argues that the European Commission, the member states, the European Parliament and other stakeholders need to give serious consideration to introducing some kind of ‘dynamic’ adjustment provision to address the relatively inelastic supply. The report also suggests that there is a need to improve communication of market-sensitive information, for example by leaving the management of the ETS to a specialised body.

This paper examines and analyses the impacts of the reformed CAP as well as the decisions of the new round of negotiations for the olive oil and cotton sectors in the European Union. The aim of this study is to estimate changes in supply (agricultural supply plus intermediate demand and final production), demand (consumption), price and stock formation (import, export, beginning and ending stocks, national price formation) for both the olive oil and cotton sectors. The model designed for this purpose is partial equilibrium and policy oriented. The objectives of this model are to estimate changes in the production and consumption of the two products concerned, to determine how the reformed CAP and the new round of negotiations of the WTO affect these two sectors to analyse the evolution of export and import volumes, and finally to determine how this evolution will influence the welfare situation of the olive and cotton sectors.

O presente artigo pretende analisar os compromissos assumidos pela Rússia quando de sua acessão à Organização Mundial de Comércio (OMC), a fim de averiguar os impactos que esses podem trazer ao sistema multilateral de comércio. A Rússia era a última grande economia que estava ausente da OMC e, para que sua acessão fosse aceita pelos membros da organização, submeteu-se a uma série de obrigações que concediam aos demais membros maior acesso ao mercado russo e visavam assegurar que o país conformaria seu sistema econômico às regras do sistema multilateral. Assim, foram estabelecidas obrigações em temas relacionados ao setor de petróleo e gás, à participação do Estado na economia, aos programas de subsídio e à observância das regras de propriedade intelectual. A partir da análise de tais compromissos, em conjunto a uma comparação com a acessão da China à OMC, em 2001, serão identificadas as principais características da economia russa que poderão ensejar desafios à sua plena participação no sistema multilateral

The negotiations of mega agreements between the US and the Pacific countries (TPP) and between the US and the EU (TTIP) are raising the attention of experts on international trade law and economics. TPP and TTIP are proclaimed to be the designers of the rules for the XXI Century. Old trade instruments such as tariffs are said to be no more important for TTIP because tariffs are negligible among those partners but significant to for TPP. Another relevant agreement in negotiation is between the EU and Mercosul, where tariffs are the most important issue in discussion. The main purpose of this paper is to shows that tariff are important for all these agreements, not because of its nominal value, but because the impacts of exchange rate misalignments on tariffs are so significant that all concessions can be distorted by overvalued and by devaluated currencies. The article is divided into several sections: the first gives an introduction to the issue; the second explains the methodologies used to determine exchange rate misalignments and also presents some results for Brazil, US and China; the third summarizes the methodology applied to calculate the impacts of exchange rate misalignments on the level of tariff protection through an exercise of “misalignment tariffication” and examines the effects of exchange rate variations on tariffs and their consequences for the multilateral trading system; the fourth creates a methodology to estimate exchange rates against a basket of currencies (a virtual currency of the World) and a proposal to deal with persistent and significant misalignments related to trade rules. The fifth presents some estimates for the main PTAs. The conclusions are present in the last section

One of the main objectives of the Bretton Woods negotiations was to guarantee the firm control over competitive exchange rate devaluations, which had worsened the effects of the economic crisis of the 1930s. The par value exchange rate system was thus created, representing a link between the international financial system and the international trading system, guaranteeing, to the latter, the neutrality of the currency issue. The present article analyses how the institutional revolutions suffered by the IMF ended up representing the loss of this link and discusses its consequences to the WTO

This dissertation uses an empirical gravity equation approach to study the relationship between nonreciprocal trade agreements (NRTAs) and members’ trade flows. Estimations relate bilateral imports to trade policy variables using a very comprehensive dataset with over fifty years of data. Results show that meager average trade effects exist only if members are excluded from the world trading system or if they are very poor. As trade flows between NRTA members are already rising before their creation, results also suggest a strong endogeneity concerning their formation. Moreover, estimations show that uncertainty and discretion tend to critically hinder NRTA’s performance. On the other hand, reciprocal trade agreements show the opposite pattern regardless of members’ income status.Encouraging developing countries’ openness to trade through reciprocal liberalization emerges consequently as a possible policy implication.

The Multilateral Trading System has evolved and presented new international mandatory rules to States. Along with the World Trade Organization constitutive treaty, Brazil has incorporated the Agreement on Subsidies and Countervailing Measures (ASCM) in the national legal system. That treaty limits de scope of subsidies concession by governments since this practice can constitute a mechanism of commercial disloyalty, affecting national industrial development in the importing country. At the same time, the multilateral agreement grants defense legitimate instruments to States, among them the possibility of domestically and unilaterally imposing countervailing measures to subsidized products that enter the national territory. Since the issue concerns both international and domestic level in complementary grounds, this research, besides investigating the treaty related obligation, aims at studying the national legal fundaments to ASCM s application by the Brazilian State. Therefore, the essential point resides in the State s conduction of its international trading and also in its available and constitutionally established mechanisms of economic intervention. State s regulating power reveals itself as a fundamental prerogative to succeed in the internalization of international agreement s requirements in the domestic legal system, which represents a basic prerequisite to the implementation of countervailing measures. Once the whole normative outlines are apprehended, this study shall scan the administrative process of trading defense main elements, along with the means of controlling public administration acts. The action taken by the public organs that directly intervene in foreign trade shall be analyzed as well, so as to enable reasoning if the unilateral application of countervailing duties by the Brazilian State is happening on legitimacy grounds

Utilizando resultados de trabalho estatístico com base nos dados da Relação Anual de Informações Sociais (RAIS), que permitem caracterizar a indústria de calçados de Nova Serrana (MG) como um sistema local de produção, e nos resultados de pesquisa de campo efetuada em abril de 2002, quando foram realizadas entrevistas e visitas em empresas e instituições locais, o artigo estuda o sistema local de produção de Nova Serrana tanto em termos do sistema como um todo quanto das empresas e instituições que o compõem. O objetivo é produzir, nesses dois níveis de análise, evidências que possam orientar ações públicas e privadas, visando ao aprimoramento do sistema e das empresas locais em duas esferas: (1) produtiva e tecnológica, em seus vários desdobramentos, e (2) institucional e organizacional. Para isso, caracteriza e dimensiona primeiramente o sistema local em termos de sua localização e região de influência, sua logística, população e empregos gerados, história e evolução, estrutura de produção, instituições de apoio, contexto social, cultural e político. em seguida, caracteriza as empresas em termos de tamanho e quanto a: desenvolvimento de produto, sistemas de comercialização, relações cooperativas, interações com fornecedores, fontes de informação para desenvolvimento de produtos e sobre mercados e processos de fabricação, práticas e políticas quanto à qualidade, ao financiamento e a outros aspectos pertinentes ao caso em estudo. Por fim, ressalta os problemas mais relevantes que podem ser objeto de políticas públicas e/ou de ações conjuntas das empresas e instituições locais.
