An optimizingmodel, with a flexible-price sector and a sticky-price sector, ispresented to analyze the effects of relative-price changes on inflation fluctuations. Therelative price of the flexible-price good represents a shift parameter of the NewKeynesian Phillips curve. The optimal monetary...

This paper studies an advantage of commitment over discretion when a central bankobserves only noisy measures of current inflation and output, in the context of an optimizingmodel with nominal-price stickiness. Under a commitment regime, if current policy turns outto be too expansionary...

Few propositions in macroeconomics are less controversial than long-run money neutrality, yet clear and robust empirical support has not been found in time series studies. Bernanke and Mihov (1998) are comparatively successful in this hunt, but their output response to monetary policy shocks...

New Keynesian models of monetary policy assign no role to monetary aggregates, in the sense that the level of output, prices, and interest rates can be determined without knowledge of the quantity of money. We evaluate the empirical validity of this prediction by studying the effects of shocks...

The central bank's optimal objective function is analyzed in a small open economy model allowing for incomplete exchange rate pass-through. The results indicate that social welfare can only be marginally improved by including an explicit exchange-rate term in the delegated objective function,...

A structural rational expectations model of U.S. monetary policy is used to make a counterfactual experiment of a strongly inflation averse Federal Reserve Bank. Results for U.S. interest rates, output, and inflation over 1965-1999 are discussed. -- Optimal monetary policy ; rational...

This paper studies the importance of money for inflation in the euro area. An inflation equation is derived from a small model that combines the supply and demand for money with a Phillips curve and the assumption that inflation expectations develop adaptively. The model's solution attributes an...

In this paper we incorporate a labor market with matching frictions and wage rigidities into the New Keynesian business cycle model. In particular, we analyze the effect of a monetary policy shock and investigate how labor market frictions affect the transmission process of monetary policy. The...

This paper examines the methods used by the Bank of Japan for the estimation of the output gap. Attention is paid to the real-time estimation problem. After reviewing the evolution of output gap estimation at the Bank, I discuss advantages and disadvantages of the various output gap measures....

In this paper an anti-cyclical fiscal policy rule is introduced into a dynamic stochastic general equilibrium model with New-Keynesian features. The rule allows the deficit to deviate from target in proportion to the impact of automatic stabilisers while any additional impact on the deficit, for...
