Abstract: Although policymakers and commentators have repeatedly stressed the impact of uncertainty about the true state of the economy on the setting of interest rates, the academic literature has largely ignored this issue. This paper provides a theoretical analysis of how uncertainty about the true state of the economy affects optimal monetary policy rules and presents empirical evidence using data for the UK since the introduction of inflation targets in October 1992. We find that the impact of inflation on interest rates is smaller when inflation is more uncertain and larger when the output gap is more uncertain; we also find that the impact of the output gap is smaller when the output gap is more uncertain. We also find that uncertainty has reduced the volatility but has not affected the average value of interest rates.
