A concorrência intramodal é uma forma de mitigação dos problemas derivados de um monopólio natural. Os setores assim estruturados caracterizam-se por elevados custos fixo e a fundo perdido, com grandes economias de escala e necessidade de elevada escala mínima de eficiência para viabilização da atividade. Essas circunstâncias impedem que a concorrência, em seu sentido mais óbvio, seja ali instaurada. Esse é o caso do setor ferroviário, onde se verifica a inviabilidade econômica de duplicação da infraestrutura. Entretanto, a depender da política regulatória adotada pelo Estado, um ambiente mais competitivo pode ser instaurado. O trabalho propõe uma análise comparada entre o modelo regulatório implementado na Alemanha, a partir das reformas ferroviárias propostas pela União Europeia, buscando extrair da experiência estrangeira aprendizados quanto aos dilemas enfrentados e características desejadas ao modelo institucional brasileiro para as novas concessões ferroviárias nacionais previstas no Plano Nacional de Investimento em Logística (PIL). O objetivo da análise consiste em verificar qual foi o modelo regulatório aplicado pela Alemanha para garantir parâmetros satisfatórios de concorrência intramodal e o modelo proposto pelo Governo Federal, com o objetivo de incentivar a ampliação do uso desse modal na cadeia logística brasileira, assim como aumentar a densidade da malha. Para permitir uma efetiva comparação dos modelos, faz-se necessário proceder preliminarmente a um breve entendimento sobre os arranjos regulatórios existentes que objetivam garantir o acesso à malha ferroviária: o tráfego mútuo, o direito de passagem e as formas de unbundling. A hipótese de investigação consiste em observar que as mudanças na regulação setorial que estão sendo consideradas pelo governo brasileiro se distanciam tanto do modelo que foi utilizado para a desestatização do setor, nos anos 90, quanto da experiência alemã de unbundling.

O mercado de capitais brasileiro não é representativo do tamanho de sua economia. Nos últimos anos, o crescimento observado nas áreas de serviços, indústria, agronegócio, e outras, não foi acompanhado pelo mercado financeiro. A estrutura verticalizada e o posicionamento monopolista da BM&F Bovespa, única bolsa de valores em atuação no mercado local, vão de encontro ao cenário encontrado em mercados internacionais. O advento da eletronificação e a atuação dos agentes reguladores proporcionaram que os mercados internacionais operassem em ambientes com múltiplas bolsas, incentivando a competitividade e trazendo benefícios para o investidor final, como redução de custos explícitos e implícitos, melhoria dos serviços prestados, diversidade de produtos, etc. Artigos recentes comprovam o benefício da fragmentação de ordens, e podem ser usados como referência no incentivo à quebra do monopólio que existe hoje no mercado brasileiro.

In a country of continental dimensions as Brazil, one of the top challenges to its economic growth is the logistic related to energetical demand supply. We live now in the era of environmental protection and, in this new context of priorizations, it passes trough the search for alternative energies for the energetic matrix, due the petroleum elevated costs in the global market (and its finitude), but also due its pollution over the environment. This attempt of substitution needs solutions related to the national reality, into a national long term developing plan and based at a juridical-economic analysis of its realization. This study will look for, also based in an economical analysis, the juridical legitimity of choosing natural gas as the new protagonist of national economic growth (as a substitute of petroleum) and the necessary boost that must be done by law, based on an economic policy focused strictly for that fact, as a modifying agent of this reality. This study, therefore, will always be turned to a constitutional aspect, respecting the principles of economic order and the goal of reducing regional inequalities, which must influence the making off of a developing plan. At the end, it will try to demonstrate the juridical viability of such undertaking, tuned in jus-economical criteria. Another goal is related to the analysis of the natural gas industry, due the regulation of its transport has a major importance for national energetic integration, not only because this activity be characterized as a net industry, still under control of a natural monopoly, but also because the competitive or cooperative profile that should be priorized at the beginning of the economic planning for this activity (such as investment policies and its own rules that will submit private agents)

Under the circumstances of the desestatization that penetrate Brazilian economy in the 90‟s, new features in the monopoly of oil by the Union were designed by the constitutional amendment number 9. of 1995. This deep change in the legal regime of oil sector brought the possibility of entrance to small and medium size producers in this industry, especially through the production activities developed in mature and marginal fields of oil, which are located mainly in northeast region of Brazil. Considering that the intervention of state over the economy finds its guidelines and limits in Federal Constitution disposals, the present work investigated in which way states regulation, mainly through taxation rules, has obeyed the constitutional regime in force, and specially, the reduction of regional inequalities principle. By mean, firstly, of an analysis of central concepts (mature fields, marginal fields, small and medium size producers) we observed that the imprecision over the conceptual aspect has constituted an obstacle to a specific states‟ regulation, directed to this newborn class of producers, whose growth has been pursuit by the state. That is verified in the case of concession procedures, and also, concerning the taxation system applied to small and medium size producers. Examining the main constitutional principles related to this universe which are the legality, equality, privileged treatment to small enterprises, contributive capacity, and reduction of regional inequalities we conclude that it is legally possible, a truly specific regulation, including a special taxation regime, to the small and medium size producers whose activities are concentrate over mature-marginal fields, aiming the concretization of the Brazilian state main goals

The Oil industry in Brazil has gone through several stages during the economical, political and social historical process. However, the significative changes have happened in the last fifteen years, due to market opening arising from the relaxation of the state monopoly over the Oil deposits and its derivatives. The edition of the Constitutional Amendment #9, changing the first paragraph of the 177th item of the Federal Constitution, marked the end of a stiffness about the monopoly that the Brazilian state kept in relation to the exploration and research of Oil and Gas. The economical order was fundamental to actualize the idea contained in the #9 Amendment, since its contents has the power to set up measures to be adopted by public power in order to organize the economical relations from a social viewpoint. The new brazilian Oil scenery, called pre-salt, presents itself in a way to amaze the economical markets, in addition to creating a new perspective to the social sector. This work will identify, in this new scenario, the need for change in the legal system. Nevertheless, this subject must not be treated in a thoughtless way: being an exhaustible good, we shall not forget that the future generations also must benefit from the exploration of natural resources recently discovered. The settlement of a new regulatory mark, including the change in the concession contract model to production and sharing is one of the suggested solutions as a bill in the National Congress, in an attempt to ensure the sovereignty of the nation. The constitutionality of a new regulatory mark is questioned, starting from an analysis of the state monopoly, grounding the comprehnsions in the brazilian constitutions, the relevance of the creation of Petrobras for self-assertion of the state about the monopoly of Oil and derivatives, and its posture after the Constitutional Amendment nº 9 (1995), when a company stops having control of the state monopoly, beginning to compete in a fairly way with other companies. The market opening and private initiative are emphasized from the viewpoint of the Constitutional Principles of the Economical and Social Order. The relaxation of the monopoly regarding the exploratory activity in the Federal Constitution doesn't deprive from the Union the ownerships of underground goods, enabling to this federal entity to contract, directly or by concession of exploration of goods, to state-owned or private companies. The existing oil in the pre-salt layer transforms the scenario from very high risk to low risk, which gives the Union the possibility of defining another way of exploring this resources in the best interests of the Public Administration

PETROBRAS, a Brazilian oil company, follows principles of public administration and from the Constitutional Amendment 9/95 in Brazil began to compete with other companies with the flexibility of the oil monopoly. In this new model started to use the simplified procedure for bidding so that could compete on equal terms. The ordinance that adopted a simplified procedure for bidding has been the subject of some criticism and lawsuits especially under the Court of Audit and the Supreme Court in Brazil. The analysis of their constitutionality, and the possibility of their use by other group companies is the theme of this work, and for this purpose, permeates through the notions of judicial review in the Brazilian law on the stage of law and economics analysis of the norm, and the principles applicable to PETROBRAS and the devices most frequently asked about the implementation of 2745/98 Decree. For this, the basic issue that should be investigated further is the regulatory power of the Federal Executive and the delegation of powers within the legislature and its conformation to the constitutional regency

In the middle of modern social changes produced by globalization and capitalism, several markets have changed. States have left the direct coordination of these markets (chiefly public utility sector in the form of monopolies), introducing regulation in order to promote competition. These changes have affected natural gas industry by promoting competition as a key factor to the development and the increase of firms in this market. The regulatory reform of natural gas industry ocurred in EUA and Europe Union and it has produced its first results. In Brazilian context, Constitutional Amendment nbr. 09 and Federal Law nbr. 9.478/97 ( Petroleum Law ) opened the natural gas market to a broad range of private economic agents and they finished the monopoly over the industry before managed by Petrobras. The new regulatory framework of Brazilian natural gas industry has designed competition as a central element to the new form of managment of business and contractual relationships of this industry. Among the regulatory instruments, open access regulation in natural gas pipelines is directed to promote competition. The questions arised about its implementation in Brazilian context are studied in the present work, in which it is discussed the constitutional rules and principles are to be applied to the open access regulation within the theme of statal regulation of economy present in constitutional economic order

This thesis endorses the interpretation that in Plato`s Republic the argument made by Thrasymachus in which justice is the convenience of the most powerful one is implicitly accepted by Socrates. Although Thrasymachus´ discussion does not show any similarity with the argument of Socrates, it proposes a sarcastic and ironic comment on political life. Socrates accepts this comment to develop a more refined notion of the category of the most powerful ones. While Thrasymachus assumes that the convenience of the most powerful ones includes the power to subordinate all and everything to their individual pleasures, Socrates admits that the most powerful ones are defined only by their characteristic of being able to hold power in perpetuity. In this context, the main theme of The Republic is that the harmony between the functional classes of the city is convenient for perpetual power. For preservation of harmony, the functional class of the most powerful considers the convenience of forsaking a possible monopoly on pleasure towards a redistribution that promotes harmony, which also makes it convenient for the other classes. Thus, we can explicitly say that the most powerful ones believe in a sense of justice as convenience for everyone, but implicitly believe only in the argument that justice is what is convenient for themselves. Since convenience is what promotes harmony between functional classes, it becomes convenient to Socrates to believe that the understanding justice that the most powerful ones have is not publicly disclosed. The notion that all the speculation of the dialogue between the characters cannot be true, but, at best, only plausible and convenient is also part of the central argument in The Republic. Socrates needs to modify the nature of the functional classes through a targeted program of sexual reproduction and a program of ideological indoctrination so that the proposal to promote harmony through the elements of the city, declaring that justice is in favor of the weakest becomes a more plausible and convenient speech. To make the new system more plausible, Socrates develops a metaphysics based on the mathematical notion of harmony, such metaphysics serving the official rhetoric of the political regime presented by Socrates

Evidencia a análise do percurso institucional e geoestratégico do Projeto Calha Norte (PCN) como processo de territorialização da fronteira política. O PCN foi pensado nos moldes convencionais da defesa e influenciado pela Doutrina de Segurança Nacional (DSN) dos anos sessenta e setenta, que objetivava e objetiva garantir o aumento da presença do Estado na Faixa de Fronteira Norte (Arco Norte), contribuindo para a Defesa Nacional e para a assistência às populações locais. Busca entender as implicações históricas, estratégicas, geopolíticas, financeiras e ambientais, desde a sua origem até os anos noventa com ênfase no governo de Fernando H. Cardoso - FHC (1994-2002). Apresenta a idéia de que a política de defesa implementada por este obedeceu às inflexões das mudanças internas na governança brasileira, bem como almejou adequá-la às transformações em curso regional e mundialmente, caracterizadas pela substituição da ordem bipolar para multipolar/unipolar, alteração no perfil das instituições políticas e, sobretudo, da integração hemisférica do país num quadro de incertezas e apelo ao fortalecimento da segurança coletiva. Essas mudanças ocorreram no contexto da modernização capitalista, na qual o PCN é concebido como uma modalidade particular de intervenção e expansão do Estado, que tem o uso exclusivo do monopólio da força, cumprindo suas prerrogativas constitucionais numa área marrom - ausência do Estado enquanto um conjunto de burocracias funcionando efetivamente numa área de baixa densidade demográfica. A ineficácia dessas dimensões do Estado define a peculiaridade do circuito da ilegalidade, isto é, o locus das atividades ilícitas tais como o narcotráfico e o contrabando. Assim, a racionalidade presente na ação do Estado consiste em articular os elementos capazes de estimular a materialização de um processo de homogeneização do espaço social na fronteira política em contexto de integração e cooperação com os países da Pan-Amazônia. Baseando-se em indicadores demográficos, econômico-financeiros e ambientais, e numa ampla base de dados sobre a Faixa de Fronteira Norte, a pesquisa concluiu pela necessidade da intervenção na fronteira política, onde o Estado busca cumprir, relativamente, sua função para ordenar e disciplinar as relações e os processos sociais a partir de referências constitucionais; afirmou que o esvaziamento financeiro deveu-se menos ao programa governamental para ajustar as contas públicas e o pagamento da dívida externa do que à decisão política de reorientar os investimentos para o Projeto; provou-se que há um movimento para a inclusão efetiva da sustentabilidade na nova PDN (Política de Defesa Nacional) e; finalmente, argumentou-se a favor da necessidade de integrar o PCN ao sistema de produção de informações do SIVAM entendido como um novo enfoque sobre a defesa nacional na Era da Informação, e que é necessário para a vigilância da região.
