Optimal Monetary Policy in a Small Open Economy: A General Equilibrium Analysis

This paper uses a model of a small, open economy to address two monetary policy issues: 1) What restrictions on the policy rule ensure that the central bank does not introduce real indeterminacy into the economy? and 2) What is the optimal long-run rate of inflation? The model’s simplicity makes analyzing determinacy issues remarkably transparent. As for long-run inflation rates, a small, open economy takes the foreign nominal interest rate as a given. To the extent that this rate distorts domestic behavior, positive domestic nominal rates (in contrast to Friedman’s celebrated optimum quantity of money) play a role.
