Creator: Kiyotaki, Nobuhiro. and Wright, Randall. Series: Working paper (Federal Reserve Bank of Minneapolis. Research Dept.) Number: 464 Abstract:
The classical and early neoclassical economists knew that the essential function of money was its role as a medium of exchange. Recently, this idea has been formalized using search-theoretic noncooperative equilibrium models of the exchange process. The goal of this paper is to use a simple model of this class to analyze four substantive issues in monetary economics: the interaction between specialization and exchange, dual fiat currency regimes, the welfare improving role of money, and the susceptibility of monetary economies to extrinsic uncertainty.

Creator: Aiyagari, S. Rao., Wallace, Neil., and Wright, Randall. Series: Lucas expectations anniversary conference Abstract:
A pairwise random meeting model with money is used to study the nominal yield on pure-discount, default-free securities that are issued by the government. There is one steady state with matured securities at par and, for some parameters, another with them at a discount. In the former, exogenous rejection of unmatured securities by the government is necessary and sufficient for such a steady state to display a positive nominal yield on unmatured securities. In the latter, the post-maturity discount on securities induces a deeper pre-maturity discount even if there is no exogenous rejection of unmatured securities.

We extend the analysis of Kiyotaki and Wright, who study an economy in which the different commodities that serve as media of exchange are determined endogenously. Kiyotaki and Wright consider only symmetric, steady-state, pure-strategy equilibria, and find that for some parameter values no such equilibria exist. We consider mixed-strategy equilibria and dynamic equilibria. We prove that a steady-state equilibrium exists for all parameter values and that the number of steady-state equilibria is generically finite. We also show, however, that there may be a continuum of dynamic equilibria. Further, some dynamic equilibria display cycles.
