We consider an infinite horizon exchange economy with incomplete markets and default. As in Geanakoplos and Zame (1998) financial securities are traded if the promises associated with them are backed by collateral. The only collateral available in our economy are shares of Lucas trees. We prove...

The work studies the properties of a coordination game in which agents repeatedly compete to be in the population minority. The game reflects some essential features of those economic situations in which positive rewards are assigned to individuals who behave in opposition to the modal behavior...

We consider the Bovespa economic index (Ibovespa) from January 1994 to the present. Starting directly from this high resolution data we study the statistical properties of the time evolution of the Ibovespa. In order to obtain price dynamics information we find the probability density function...

On last yearÌs conference in Barcelona the authors presented an innovative expectation formation hypothesis. The assumption of fully rational agents is rejected and replaced by a bounded rationality approach that is modelled by means of a fuzzy rule-base. These rules as well as their components...

Economic fluctuations are much stronger in developing countries than in the United States. Yet, while a large literature debates what constitutes a reasonable estimate of the welfare cost of business cycles in the US, it remains an open question how large that cost is in developing countries....

In this paper we study the effects of shocks (a slowdown in TFP growth and an increase in the real interest rate) in a model with endogenous job destruction and job creation. We show that both increase the job destruction margin and the job rejection margin and, thus, the unemployment rate....

A wealth of literature, reviewed in the first section of this paper, is concerned with the occurence of multiple equilibria in economic optimization models and with the resulting history dependence of optimal solutions. Typically, the existence of multiple equilibria is associated with market...

This paper studies the behavior of price discovery within a context of an agent based stock market in which the twin assumptions namely, rational expectations and the representative agents normally made in mainstream economics, are removed. In this model, traders stochastically update their...

Recent developments in the aggregation of large cross section of linear time series processes provide a complete characterization of the link between the dynamic properties of the aggregate series and the shape and degree of heterogeneity of the coefficients of the micro time series (see Lippi...

This paper examines the implications of a 'strong' version of bounded rationality popular within computational and evolutionary game theory in which agents are represented by finite automata. It is argued that this view has unrealistic features in that agents of this kind are unable to...
