This paper extends recent findings in the search-theoretic literature on monetary exchange regarding the welfare costs of inflation. We present first estimates of the welfare cost of inflation using the welfare triangle methodology of Bailey (1958) and Lucas (2000). We then derive a money demand...

We develop a dual currency search model to study equilibrium currency exchange and the determination of nominal exchange rates. Agents hold portfolios consisting of two distinct currencies. We study equilibria in which the two currencies are identical and equilibria in which the two currencies...

We analyze a dual currency search model in which agents are allowed to hold multiple units of both currencies. Hence, agents hold portfolios of currency. We study equilibria in which the two currencies are identical and equilibria in which the two currencies differ according to the magnitude of...
