The Second Welfare Theorem with public goods in general economies

In this paper we prove a general version of the Second Welfare Theorem for a non-convex and non-transitive economy, with public goods and other externalities in consumption. For this purpose we use the sub-gradient to the distance function (normal cone) to define the pricing rule in this general context.Non-convex separation, Second Welfare Theorem, public goods, externalities.

Supporting weakly Pareto optimal allocations in infinite dimensional nonconvex economies

In this paper, we prove a new version of the Second Welfare Theorem for economies with a finite number of agents and an infinite number of commodities, when the preference correspondences are not convex-valued and/or when the total production set is not convex. For this kind of nonconvex economies, a recent result obtained by one of the authors, introduces conditions which, when applied to the convex case, give for Banach commodity spaces the well-known result of decentralization by continuous prices of pareto optimal allocations under an interiority condition. In this paper, in order to prove a different version of the Second Welfare Theorem, we reinforce the conditions on the commodity space, assumed here to be a Banach lattice, and introduce a nonconvex version of the properness assumptions on preferences and the total rpoduction set. Applied to the convex case, our result becomes the usual Second Welfare Theorem when properness assumptions replace the interiority condition. The proof uses a Hahn-Banach Theorem generalization by Borwein-Jofré which allows to separate nonconvex sets in general Banach spaces.Second welfare theorem; nonconvex economies; Banach spaces; subdifferential; Banach lattices; Properness assumptions

Mechanism Design and Auctions for Electricity Network

We present some key aspects of wholesale electricity markets modeling and more specifically focus our attention on auctions and mechanism design. Some of the results arising from those models are the computation of an optimal allocation for the Independent System Operator, the study of the equilibria (existence and unicity in particular) and the design of mechanisms to increase the social surplus. From a more general perspective, this field of research provides clues to discuss how wholesale electricity market should be regulated. We start with a general introduction and then present some results the authors obtained recently. We also briefly expose some undergoing related work. As an illustrative example, a section is devoted to the computation of the Independent System Operator response function for a symmetric binodal setting with piece-wise linear production cost functions

Epistemological Obstacles for Conceptual Production in Social Sciences : : the case of the “Global Capitalist System" Concept.

Se intenta esclarecer cómo ciertos factores materiales, en determinados momentos históricos, influyen en el retraso del surgimiento de un corpus teórico que dé cuenta, con la mayor exactitud, de la realidad social. Más precisamente, se pretende evidenciar las condiciones materiales que obstaculizan el surgimiento del concepto de sistema capitalista global, considerando que su objeto real ya estaba plenamente presente hacia la segunda mitad del siglo XIX. Para esto se ilustraran algunos esbozos del concepto, elaborados desde la periferia del sistema global que, independientemente de su pertinente enunciación, fueron bloqueados en su desarrollo por condiciones políticas e ideológicas particulares.An attempt is made to clarify how some material factors, at some point in history, influence the delay of the resurgence of a theoretical corpus that may accurately account for social reality. More precisely, it is intended to give evidence of the material conditions that form an obstacle for the resurgence of the global capitalist system concept, considering that its real object was already totally present by the second half of the XIXth century. To this purpose, some outlines of the concept are illustrated, worked out from the periphery of the global system which, independent from its pertinent enunciation, was blocked in its development by specific political and ideological conditions.Fil: Jofré, José Luis.

Narraciones identitarias, violencia, politica y civilidad: el psicoanalisis frente a los ensueños colectivos

Abstract This article establishes an analysis regarding the senses that organize the identity narratives in their links with the political dimension and violence. It also provides a detailed reflection on the socio-historical foundations involved in the making of such senses. To achieve this, the historical scopes of the political philosophy, and the relationships they evince with the Freudian proposals related to the cultural dimension of politics, are considered. A wide number of important statements is made concerning the political actions that might be established in the face of the devastating course of the identity violence.    Key words: violence, politics, identity, civilization, psychanalysisEl presente artículo establece un análisis relativo a los sentidos que organizan las narraciones de las políticas identitarias, considerando sus vínculos históricos y sociales con la dimensión de la violencia extrema. Para ello, se toman en cuenta ciertos alcances históricos de la filosofía política, analizando las relaciones que estos evidencian con las propuestas freudianas relativas a la dimensióncultural de la política. Un número igualmente importante de enunciados es elaborado a propósito de las acciones políticas que pueden ser establecidas frente al curso.El presente artículo establece un análisis relativo a los sentidos que organizan las narraciones de las políticas identitarias, considerando sus vínculos históricos y sociales con la dimensión de la violencia extrema.
