Monetary Policy, Price Dynamics, and Welfare∗

چکیده
We present a micro-founded search-theoretical model of money in which agents are subject to idiosyncratic liquidity shocks as well as aggregate productivity and monetary shocks. Monetary policy has redistributive effects and persistent effects on output and prices: aggregate shocks will propagate and diffuse gradually as the money distribution adjusts over time. The model is used to study the cyclical properties of the model, the welfare costs of unanticipated inflation, the short-run (real) effects of unanticipated monetary shocks, and to evaluate the welfare of different monetary policy rules. An algorithm based on the one proposed by Algan, Allais, and den Haan (2007) is presented and used to solve the model. J.E.L. Classification Numbers: E40, E50

This paper develops a general equilibrium exchange rate model consistent with the weak empirical evidence supporting the law of one price. Some firms segment markets by country, and set prices in local currency of sale, a practice we refer to as pricing-to-market (PTM). The presence of PTM increases exchange rate volatility, relative to a situation where the law of one price holds. PTM also aff...
