Ce papier presente un modele d'equilibre general de concurrence imparfaite dans une economie d'echange avec generations imbriquees. La concurrence imparfaite se traduit par la regle de fixation du prix des jeux strategiques du marche a la Shapley-shubik. Apres avoir presente le modele et defini...

This chapter reviews the theory of the voluntary public and private redistribution of wealth elaborated by economic analysis in the last forty years or so. The central object of the theory is altruistic gift-giving, construed as benevolent voluntary redistribution of income or wealth. The theory...

Can monetary or fiscal policy stabilize expectations in a liquidity trap? We study expectation formation near the zero lower bound using a learning-to-forecast laboratory experiment. Monetary policy targets inflation around a constant or state-dependent target. Subjects’ expectations...

The conventional search and matching model has been criticized for its inability to explain large cyclical volatility in the vacancy-unemployment ratio without ad hoc assumptions of wage rigidity. This paper presents a mechanism of such volatility without assuming wage rigidity by showing that...

This paper explores the importance of accessible and focal information in influencing beliefs and attention in a learning-to-forecast laboratory experiment where subjects are incentivized to form accurate expectations about inflation and the output gap. We consider the effects of salient and...

En esta investigación se desarrolló un modelo de economía estocástica, pequeña y abierta, poblada por consumidores racionales idénticos que tienen vida finita, pero estocástica; además, son adversos al riesgo y disponen de una riqueza inicial. Estos agentes enfrentan la decisión de...

En este trabajo se desarrolla un modelo de equilibrio general en una economia con agentes identicos. Estos agentes son racionales y toman decisiones de portafolio y consumo. Bajo los supuestos de que existe una accion cuyo precio es conducido por un movimiento geometrico Browniano y la...

We consider an exchange economy with time-inconsistent consumers whose preferences are additively separable. When these consumers trade in a sequence of markets, their time-inconsistency may introduce a non-convexity that gives them an incentive to trade lotteries. If there are many consumers,...

Many consumers care about climate change and other externalities associated with their purchases. We analyze the behavior and market effects of such "socially responsible consumers" in three parts. First, we develop a flexible theoretical framework to study competitive equilibria with rational...

This paper shows that a Nash equilibrium consisting of strategies of choosing a Pareto inefficient transition path is selected by households even without frictions as a result of the revealed government failure in supervision of financial markets. The Pareto inefficiency causes the generation of...
