Abstract: In this paper we estimate a small macroeconometric model of the United States, the euro area and Japan with rational expectations and nominal rigidities due to staggered contracts. Comparing three popular contracting specifications we find that euro area and Japanese inflation dynamics are best explained by Taylor-style contracts, while Buiter-Jewitt/Fuhrer- Moore contracts perform somewhat better in fitting U.S. inflation dynamics. We are unable to fit Calvo-style contracts to inflation dynamics in any of the three economies without allowing either for ad-hoc persistence in unobservables or a significant backward-looking element. The completed model matches inflation and output dynamics in the United States, the euro area and Japan quite well. We then use it to evaluate the role of the exchange rate for monetary policy. Preliminary results, which are similar across the three economies, indicate little gain from a direct policy response to the exchange rate.
Abstract: The paper uses capital and labor utilization rates to derive estimates of the Japanese output gap and potential output. Two techniques are used. The first uses the cyclical indicators to adjust potential output estimates derived from a Hodrick-Prescott filter over the most recent period when such estimates are generally considered to be unreliable. The second estimates equilibrium levels of the cyclical indicators and uses an Okun's Law-type relationship to derive output gaps and potential output. The second method is also applied to the components of potential output to derive a third estimate. These methods suggest that the current Japanese output gap is considerably larger than a simple Hodrick-Prescott filter would suggest.
