This paper formalizes the relation between comparative statics and the out-of-equilibrium explanation for how a system evolves after a change in parameters.

We apply the stochastic evolutionary approach of equilibrium selection to macroeconomic models in which a complementarity at the macro level is present. These models often exhibit multile Pareto-ranked Nash equilibria , and the best response-correspondence of an individual increases with a...

In this paper the existence of unemployment is partly explaines as being the result of coordination failures. This is achieved by considering a standard general equilibrium modes and splitting the set of commodities in two groups. The first group contains commodities like gold. The prices of...

In this paper, we prove an existence theorem for equilibria in production economies with increasing returns, which generalizes the classis results on this topic. In partular, we eliminate both the free-disposal assumptions and any smoothness requirements on the boundary of the production sets....

In contrast to the neo-classical theory of Arrow and Debreu, a model of a private ownership economy is presented, in which production and consumption bundles are treated separately. Each of the two types of bundles is assumed to establish a convex cone. Production technologies can convert...

This paper shows how to make hold the conjecture stated in Maskin an Tirole about the existence of a close connection between the finite, markovian stationary equilibria of a simple overlapping generations economy and the correlated equilibria of an associated finite exchange economy with...

In this paper, we define and study a new class of optimal stochastic control problems which is closely related to the theory of Backward SDE's and forward-backward SDE's. The controlled process takes values in RXR and a given initial data for X(O). Then, the control problem is to find the...

We present and prove the equality between the core and the set of Walras allocations for a pure exchange economy with l goods and a continuum of consumers, represented by an atomless measure space.

Prime objects of this note are (I) excess demand generated by price-taking economic agents, and (II) an alternative version of tatonnement. We relate laws of demand, axioms of revealed preferences, and other notions of generalized monotonicity to evolutionary stable prices. Focus is on local...
