Abstract

Abandoning an objective function with multiple targets and adopting a single mandate is an effective way for a central bank to overcome the classic time-inconsistency problem. We show that the choice of a particular single mandate depends on a country's level of trade openness. Both inflation targeting and nominal exchange rate targeting come with their own costs. We show that the costs of inflation targeting are increasing in a country's level of trade openness while the costs of exchange rate targeting are decreasing in trade openness. Thus a relatively closed economy will prefer an inflation targeting mandate and a very open economy will prefer an exchange rate target. Empirical results show that as central banks become less credible they are more likely to adopt a pegged exchange rate, and crucially the empirical link between central bank credibility and the tendency to peg depends on trade openness.
