Abstract

This paper analyses the implications of cost-push shocks for the optimal choice of monetary policy target in a two-country sticky-price model. In addition to cost-push shocks, each country is subject to labour-supply and money-demand shocks. It is shown that the fully optimal coordinated policy can be supported by independent national monetary authorities following a policy of flexible inflation targeting. A number of simple (but non-optimal) targeting rules are compared. Strict producer-price targeting is found to be the best simple rule when the variance of cost-push shocks is small. Strict consumer-price targeting is best for intermediate levels of the variance of costpush shocks . And nominal-income targeting is best when the variance of costpush shocks is high. In general, money-supply targeting and fixed nominal exchange rates are found to yield less welfare than these other regimes. Classification-
