We include endogenous differential information in a model with sequential trade and incomplete financial participation. Agents update information through market signals given by commodity prices and asset deliveries. Information acts over admissible strategies and consumption tastes, allowing discontinuities in preferences and choice sets. Therefor...

We build a general equilibrium model with endogenous borrowing constraints compatible with credit segmentation. There are personalized trading restrictions connecting prices with both portfolio constraints and consumption possibilities, a setting which has not thoroughly been addressed by the literature. Our approach is general enough to be compati...

In this work, we study an alternative approach for capping and pricing carbon emissions in electric markets: the cap-and-trade paradigm with re-trade of allowances. We model the electric market (generators and allowances’ auctioneer) as a two stage stochastic capacity expansion equilibrium problem, where we allow future investment and re-trading of...

In the context of the Paris Agreement, Chile has pledged to reduce Greenhouse Gases (GHG) intensity by at least 30% below 2007 levels by 2030, and to phase out coal as a energy source by 2040, among other strategies. In pursue of these goals, Chile has implemented a $5 per tonne of CO2 emission tax, first of its kind in Latin America. However, such...

Exchange economies are defined by a mapping between an atomless space of agents and a space of characteristics where the commodity space is a separable Banach space. We characterize equilibrium stability of economies relaying on the continuity of the equilibrium correspondence. We provide a positive answer to an open question about the continuity o...

In a competitive model where agents are subject to endogenous trading constraints, we make the access to financial trade dependent on prices and consumption decisions. Our framework is compatible with the existence of both credit market segmentation and market exclusion. In this context, we show equilibrium existence in two scenarios. In the first...

We build a general equilibrium model where agents are subject to endogenous trading constraints, making the access to financial trade dependent on prices and consumption decisions. Besides, our framework is compatible with the existence of endogenous financial segmentation and credit markets' exclusion. Two results of equilibrium existence are show...

Este estudio aborda los vínculos entre fraternidad y educación desde la perspectiva económica, mediante el análisis de la impor-tancia de las relaciones interpersonales y su rol en el desempeño económico. La creciente literatura sobre dichas relaciones, impul-sada sobre todo desde las ciencias sociales, se ha agrupado principalmente en torno al con...

We develop a two period general equilibrium model with incomplete financial markets and differential information. Making endogenous the traditional informational restriction on consumption, we allow agents to obtain information from physical and financial markets. Thus, the investment in financial promises and the trade of commodities in spot marke...

Usando datos del m�dulo de historia laboral de la Encuesta de Protecci�n Social para los a�os 2002, 2004 y 2006, se construy� un panel mensual para el per�odo 2000-2006. Para modelar las variables que intervienen en la decisi�n de los individuos de trabajar por cuenta propia consideramos un modelo general del mercado del trabajo, donde los individu...
