The optimal weights on indicators in models with partial information about the state of the economy and forward-looking variables are derived and interpreted, both for equilibria under discretion and under commitment. An example of optimal monetary policy with a partially observable potential...

The trade-off between interest rate variability and the width of an exchange rate target zone is examined, using the regulated Brownian motion model of target zones. The interest rate differential’s asymptotic (unconditional) variability is increasing in the exchange rate band for narrow...

It is argued that inflation targeting is best understood as a commitment to a targeting rule rather than an instrument rule, either a general targeting rule (explicit objectives for monetary policy) or a specific targeting rule (a criterion for the forecasts of the target variables to be...

How do exchange rate bands work compared to completely fixed rates (between realignments); or, more precisely, what are the dynamics of exchange rates, interest rates, and central bank interventions within exchange rate bands? Does the difference between bands and completely fixed exchange rates...

Central banks target CPI inflation; independent central banks are concerned about their balance sheet and the level of their capital. The first fact makes it difficult for a central bank to implement the optimal escape from a liquidity trap, because it undermines a commitment to overshoot the...

The credibility of the exchange rate bands in the Nordic countries during 1987-91 is examined with two tests. The results suggest that the credibility of Finland’s exchange rate band within a twelve-month horizon could not be rejected except in the fall of 1991; however, the band lacked...

An independent central bank can manage its balance sheet and its capital so as to commit itself to a depreciation of its currency and an exchange rate peg. This way, the central bank can implement the optimal escape from a liquidity trap, which involves a commitment to higher future inflation....
