The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
The paper analyzes the effects of monetary policy in a dynamic model of a small open economy with cash and credit goods production, where government consumption is financed by seignorage. It shows that the interrelationships between the growth rate of the monetary aggregate and the technological properties of the economy have an important bearing on the existence and uniqueness of equilibrium, the optimal inflation rate, and the occurrence of explosive hyperinflations. In consequence, the paper concludes that monetary policy does matter in the long run.
