The present paper revisits a property embedded in most dynamic macroeconomic models: the stationarity of hours worked. First, I argue that, contrary to what is often believed, there are many reasons why hours could be nonstationary in those models, while preserving the property of balanced...

The present paper provides an overview of recent developments in the analysis of monetary policy in the presence of nominal rigidities. The paper emphasizes the existence of several dimensions in which the recent literature provides a new perspective on the linkages among monetary policy,...

Using data for the G7 countries, I estimate conditional correlations of employment and productivity, based on a decomposition of the two series into technology and non-technology components. The picture that emerges is hard to reconcile with the predictions of the standard Real Business Cycle...

We modify the standard real business cycle model by assuming that wages are set by a monopoly union at the firm level. In the context of such a model, we introduce a measure of unemployment and analyze its equilibrium behavior. We show that a calibrated version of the model is capable of...

This paper investigates empirically and attempts to identify the sources of real exchange rate fluctuations since the collapse of Bretton Woods. The paper's first two sections survey and extend earlier, non-structural empirical work on this subject by Campbell and Clarida (1987), Meese and...

The author estimate a decomposition of productivity and hours into technology and nontechnology components. Two results stand out: (1) the estimated conditional correlations of hours and productivity are negative for technology shocks, positive for nontechnology shocks; and (2) hours show a...

We provide evidence on the fit of the New Phillips Curve (NPQ for the Euro area over the period 1970-1998, and use it as a tool to compare the characteristics of European inflation dynamics with those observed in the U.S. We also analyze the factors underlying inflation inertia by examining the...

This paper develops a new open economy macro model of optimal monetary for a small open economy. Our main result is that in this model, the optimal policy problem for the small open economy is isomorphic to the closed economy case studied in Clarida, Gali, Gertler (1999). In particular, the...

We develop a utility based model of fluctuations, with nominal rigidities, and unemployment. In doing so, we combine two strands of research: the New Key- nesian model with its focus on nominal rigidities, and the Diamond-Mortensen-Pissarides model, with its focus on labor market frictions and...
