Resumen:El artículo propone abordar algunos lineamientos básicos para la discusión filosófica en torno a conceptos del derecho, en particular respecto a la construcción de lo legítimo. La primacía ontológica de lo político en la constitución del lenguaje, que performa el sentido del discurso normativo, introduce la necesidad de revisar los fundamentos modernos con los que se determina la juridicidad. Esto impondría el desafío de desarrollar alternativas de contra-hegemonía conceptual, capaces de visibilizar, traducir y articular la pluralidad de discursos que disputan el reconocimiento de sus demandas en el espacio público-político.Abstract:This paper proposes basic guidelines for addressing some philosophical discussion about concepts of law, in particular with regard to the construction of legitimacy. The ontological primacy of politics in the constitution of language, which perform the sense of the legal discourse, introduces the need to review the fundaments of the Modernity who determining the legality. This would impose the challenge of developing alternatives of conceptual counter-hegemony, able to visualize, translate and articulate the plurality of discourses that dispute for the recognition of their claims in the public-political space.

Este trabajo es un fragmento de una investigación mayor, la cual toma los discursos de Asunción de los presidentes del Mercosur desde el año 2000 a la actualidad como su objeto. Las categorías que se analizan son dos, enunciaciones en referencia a la Economía y las Relaciones Internacionales del país. Se trabaja sobre solo dos discursos de asunción de presidentes de la República Argentina, Fernando de la Rúa y Cristina Fernández de Kirchner. Se utiliza el algoritmo David Liberman como metodología de análisis del discurso, específicamente los niveles de actos del habla y redes de palabras. El método se aplica sobre un fragmento, obtenido por el juicio interjueces, los cuales determinan la idea nuclear y las ideas complementarias para cada temática en cada discurso. ; This work is the fragment of a larger research, whose object is the assumption discourses of the Mercosur presidents, from the year 2000 to the present. The categories analyzed are two, enunciations referring to Economy and to International Relations of the country. The present article focuses on only two assumption discourses of argentine presidents, Fernando de la Ra and Cristina Fernandez de Kirchner. The methodology of discourse analysis, specifically on the speech act and word net levels, is the David Liberman algorithm. The method is applied to a fragment, proposed by inter–judge deliberation, since it's they who determine the nuclear idea as well as the complementary ones for each theme in each discourse.

In this paper the scope of Bergstrom's (1982) results is studied. Moreover, his analysis is extended assuming that extraction cost is directly related to accumulated extractions. For the case of a competitive market it is found that the optimal policy is a constant tariff if extraction is costless. However, with depletion effects, the optimal tariff must ultimately be decreasing. For the case of a monopolistic market the results depend crucially on the kind of strategies the importing country governments can play and on whether the monopolist chooses the price or extraction rate. For a price-setting monopolist it is shown that the importing countries cannot use a tariff to capture monopoly rents if they are constrained to use open-loop strategies, even if the governments sign a tariff agreement. This result is drastically modified if the importing countries in the tariff agreement use Markov (feedback) strategies. For a quantity-setting monopolist the nature of the game changes and the importing country governments find it advantageous to set a tariff on resource importations. Moreover, in this case the importing countries in a tariff agreement enjoy a strategic advantage which allows them to behave as a leader.
