CIRJE-F-417. Kamiya, Kazuya and Takashi Shimizu, "A Dynamic General Equilibrium Model with Centralized Auction Markets", April 2006.

A conventional wisdom in economics is that a model dealing frictionless markets with a large number of agents always yields a Walrasian outcome. In this paper we assess the above argument in a dynamic framework by modeling centralized auction markets, and show that in such markets the outcomes are not necessarily Walrasian; the set of stationary equilibria in our model is a continuum which includes the Walrasian equilibrium. Moreover, we also buildamodelondecentralized auction markets and obtain similar results.
