In this paper, we first give a direct proof of the existence of Edgeworth equilibria for exchange economies with consumption sets which are (possibly) unbounded below. The key assumption is that the individually rational utility set is compact. It is worth noticing that the statement of this...

The general purpose of this paper is to prove quasiequilibrium existence theorems for production economies with general consumption sets in an infinite dimensional commodity space, without assuming any monotonicity of preferences or free-disposal in production.

A simple model of the Arrow-Debreu type is used to analyze the short-run performance of an employee-controlled wage-maximizing economy. It is found that an increase in demand, caused by a shift in consumers' preferences, leads to a fall in a good's equilibrium price, which indicates that...

In the paper, an analytical framework with both increasing returns and transaction costs is developed to investigate the general equilibrium with endogenous specialization and division of labor. In this framework, each individual's optimum decision in choosing her pattern of specialization is...

We consider a general equilibrium model with a production sector. The consumption sets, the preferences of the consumers and the production possibilities are represented by set-valued mappings to take into account the possibility of external effects. There are no convexity assumptions on the...
