The standard New Keynesian model with staggered wage setting is shown to imply a simple dynamic relation between wage inflation and unemployment. Under some assumptions, that relation takes a form similar to that found in empirical applications--starting with the original Phillips (1958)...

Much recent research has focused on the development and analysis of extensions of the New Keynesian framework that model labor market frictions and unemployment explicitly. The present paper describes some of the essential ingredients and properties of those models, and their implications for...

We lay out a tractable model for fiscal and monetary policy analysis in a currency union, and analyse its implications for the optimal design of such policies. Monetary policy is conducted by a common central bank, which sets the interest rate for the union as a whole. Fiscal policy is...

We estimate a forward-looking monetary policy reaction function for the US economy, pre- and post-October 1979. Our results point to substantial differences in the estimated rule across periods. In particular, interest rate policy in the Volcker-Greenspan period appears to have been much more...

We provide evidence on the fit of the New Phillips Curve (NPC) 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 analyse the factors underlying inflation inertia by examining...

We develop a simple growth model with imperfect competition in which demand conditions can affect the dynamics of capital accumulation, hindering or enhancing growth. In our model the elasticity of the demand schedule faced by a typical firm depends on the aggregate savings rate. The latter...

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,...

The purpose of the present Paper is twofold. First, we characterize the Fed’s systematic response to technology shocks and its implications for US output, hours and inflation. Second we evaluate the extent to which those responses can be accounted for by a simple monetary policy rule...

In this Paper we present a simple, theory-based measure of the variations in aggregate economic efficiency associated with business fluctuations. We decompose this indicator, which we refer to as ‘the gap’, into two constituent parts: a price markup and a wage markup, and show that the...

Most central banks perceive a trade-off between stabilizing inflation and stabilizing the gap between output and desired output. However, the standard new Keynesian framework implies no such trade-off. In that framework, stabilizing inflation is equivalent to stabilizing the welfare-relevant...
