Working paper No. 88

We look at the implications of uncertain monetary policy preferences for the targeting and contracting approach to monetary stability. It turns out that in the presence of uncertain preferences a linear incentive contract in the sense of Walsh (1995) performs better in terms of social welfare than an explicit inflation target as proposed by Svensson (1997). The reason is that, although both approaches can get rid of the inflationary bias, the impact of uncertain preferences on the variance of inflation will be considerably higher with an inflation target. Contrary to Beetsma and Jensen (1998) we find that the optimal inflation target depends on the degree of preference uncertainty. For the case of the Walsh contract, unlike Beetsma and Jensen, we find that it is optimal to offer a linear inflation contract to a central banker that does not depend on the degree of uncertainty about its preferences.
