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...

We evaluate the Friedman-Schwartz hypothesis that a more accommodative monetary policy could have greatly reduced the severity of the Great Depression. To do this, we first estimate a dynamic, general equilibrium model using data from the 1920s and 1930s. Although the model includes eight...

This article shows that, as long as agents are required to maintain positive wealth, the presence of portfolio constraints may give rise to asset pricing bubbles in equilibrium even if there are unconstrained agents in the economy who can benefit from the induced arbitrage opportunity....

A pure exchange, general equilibrium model is considered and the equilibrium set is studied. It is shown for all total endowments and an open and dense set of preferences that if there arel2 commodities andm2 consumers then there exists a set of distributions of endowments with nonempty interior...
