The standard neoclassical growth model is modified by introducing a market structure characterized by monopolistic competition and variable demand elasticities. In equilibrium, the price elasticity of the demand schedule facing a typical firm is a function of the aggregate savings rate. The...

We document three changes in postwar US macroeconomic dynamics: (i) the procyclicality of labor productivity has vanished, (ii) the relative volatility of employment has risen, and (iii) the relative (and absolute) volatility of the real wage has risen. We propose an explanation for all three...

We estimate a version of the Smets-Wouters model with unemployment.

Central banks’ projections– i.e. forecasts conditional on a given interest rate path– are often criticized on the grounds that their underlying policy assumptions are inconsistent with the existence of a unique equilibrium in many forward-looking models. The present paper describes three...

Unemployment in an Estimated New Keynesian model

We estimate the response of stock prices to exogenous monetary policy shocks using a vector-autoregressive model with time-varying parameters. Our evidence points to protracted episodes in which, after a short-run decline, stock prices increase persistently in response to an exogenous tightening...

We study the extent of macroeconomic convergence/divergence among euro area countries. Our analysis focuses on four variables (unemployment, inflation, relative prices and the current account), and seeks to uncover the role played by monetary union as a convergence factor by using non-euro...

I examine the impact of alternative monetary policy rules on a rational asset price bubble, through the lens of an overlapping generations model with nominal rigidities. A systematic increase in interest rates in response to a growing bubble is shown to enhance the fluctuations in the latter,...

I revisit the General Theory's discussion of the role of wages in employment determination through the lens of the New Keynesian model. The analysis points to the key role played by the monetary policy rule in shaping the link between wages and employment, and in determining the welfare impact...
