A Dynamic Model of Search and Intermediation

No 2010-04, Discussion Papers from School of Economics, The University of New South Wales

Abstract: This paper develops a dynamic model of an economy with search frictions in which homogeneous agents choose between specializing as producers or as merchants, and can change occupation at any time. Merchants operate alongside a decentralized search market and provide immediacy in trade in return for a price. Agents who know the location of a merchant have the option of paying the merchant’s price and avoiding search. We characterize equilibria in symmetric Markov strategies, and derive conditions under which merchants and their clients form a repeated relationship. We analyze welfare and explore conditions for the endogenous rise of an institution of intermediation.
