This paper provides a framework for establishing the determinacy of equilibria in general equilibrium models with infinitely many commodities and a finite number of consumers and producers. This paper defines a notion of regular economy for such models and gives sufficient conditions on the...

This paper provides a framework for establishing the determinacy of equilibria in general equilibrium models with infinitely many commodities and a finite number of consumers and producers. The paper defines a notion of regular economy for such models and gives sufficient conditions on the...

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, the impersonal network of the division of labor emerges from the interactions...

In this paper we prove the existence of general equilibrium with transaction costs generalizing Hahn's (Review of Economic Studies, 1973, 40, 449-461) model by introducing producers and nonconvexities (in particular we allow for increasing returns in transaction sets). We also recover any...

In contrast to Mandler's (1999a; Theorem 6) impossibility result about the Sraffian indeterminacy of the steady-state equilibrium, we first show that any regular Sraffian steady-state equilibrium is indeterminate in terms of Sraffa (1960) under the simple overlapping generation economy. Moreover, we...

We show that Arrow-Debreu equilibria with countably additive prices in infinite-time economy under uncertainty can be implemented by trading infinitely-lived securities in complete sequential markets under two different portfolio feasibility constraints: Wealth constraint, and essentially...
