In this paper we exploit global analysis to explore welfare properties of a standard one-commodity GEI, under different notions of constrained Pareto optimality. In a unifying framework we revise and extend some of the leading results of the literature on incomplete markets and government...

In this paper we investigate the welfare effect of capital income taxation in a standard one commodity general equilibrium model with incomplete markets (GEI) and production. We consider a competitive economy of two periods with uncertainty over a finite number S of possible states of nature...

Two basic properties concerning the dynamic behavior of competitive equilibria of exchange economies with complete markets are derived essentially from the fact that the Walras correspondence has no knots.

A general notion of market perfect contestability is introduced. It coincides with the definition given by Baumol et al. under Bertrand competition, but is compatible with other forms of competition: Cournot competition as well as monopolistic competition. Using this notion,we illustrate the...

I construct and analyse an example of an economy with production and money under conditions of uncertainty, assymetric information, and an incomplete asset market. For alternative scenarios, which differ in the information available to consumers and firms, I compute the equilibrium prices and...

In an economy with a non-atomic measure space of assets and exchangeable risks, the Arbitrage pricing Theory (APT) holds exactly; and factors are structurally specified, which allows for an economic interpretation.

Long-run oligopolistic expansion behavior in an electricity supply market is modeled in this paper.

We show that there is a broad range of systems of simultaneous equations that arise in economics as descriptions of equilibrium that can be solved in elementary fashion via degree theory. Some of these systems are not susceptible to analysis by standard Brouwer fixed point methods. Two of our...

This study analyzes the impact of international trade on the diffusion of flexible manufacturing in a general equilibrium framework. Suppliers produce a flexible base product that can be adapted to the specific input requirements of a continuum of downstream industries. The vertical structure is...
