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. The private sector is assumed to have information about the state of the...

This paper discusses how price stability can be defined and how price stability can be maintained in practice. Some lessons for the Eurosystem are also considered. With regard to defining price stability, the choice between price-level stability and low (including zero) inflation and the...

Using a small empirical model of inflation, output, and money estimated on U.S. data, we compare the relative performance of monetary targeting and inflation targeting. The results show that monetary targeting would be quite inefficient, with both higher inflation and output variability. This is...

Policy rules that are consistent with inflation targeting are examined in a small macroeconometric model of the US economy. We compare the properties and outcomes of explicit "instrument rules" as well as "targeting rules." The latter, which imply implicit instrument rules, may be closer to...

Under the assumption of no arbitrage, the credibility of an exchange rate target zone is tested by whether domestic interest rates fall within "rate-of-return bands" between the maximum and minimum home currency rate of return on a foreign investment in the absence of a devaluation. Under the...

If inflation expectations become firmly anchored at the inflation target even when average inflation deviates from the target, the long-run Phillips curve becomes nonvertical. During 1997-2011, average inflation expectations in Sweden have been close to the inflation target of 2 percent, whereas...
