Walrasian equilibrium in large, quasilinear markets

Authors


Abstract

In an economy with indivisible goods, a continuum of agents, and quasilinear utility, we show that equilibrium exists regardless of the nature of agents' preferences over bundles. This contrasts with results for economies with a finite number of agents, which require restrictions on preferences (such as substitutability) to guarantee existence. When the distribution of preferences has full support, equilibrium prices are unique.
