Abstract

The unconditional expectation of social welfare is often used to assess alternative macroeconomic policy rules in applied quantative research. It is shown that it is generally possible to derive a linear-quadratic problem that approximates the exact non-linear porblem where the unconditional expectation of the objective is maximised and the steady- state is distorted. Thus, the measure of policy performance is a linear combination of second moments of economic variables which is relatively easy to compute numerically, and can be used to rank alternative policy rules. The approach is applied to a simple Calvo-type model under various monetary policy rules.
