We document that "persistent and lagged" in‡ation (with respect to output) is a worldwide phenomenon in that these short-run in‡ation dynamics are highly synchronized across countries. In particular, the average cross-country correlation of in‡ation is signi…cantly and systematically stronger than that of output, while the cross-country correlation of money growth is essentially zero. We invest...

This paper provides a complete analytical characterization of the positive and normative effects of alternative exchange rate regimes in a simple two-country sticky-price dynamic general equilibrium model with money, technology, and government spending shocks. A central question addressed is whether fixing the exchange rate prevents macroeconomic adjustment in relative prices from occurring, in...

This paper considers the macroeconomic effects of allowing for nominal debt contracts in the context of a quantitative business cycle model with financial market frictions. In our setting, as in reality, corporations fund themselves by choosing the appropriate mix of nominal defaultable debt and equity securities to issue in every period. Corporate debt is priced fairly taking into account defa...

This paper characterises optimal monetary policy in an economy with endogenous …rm entry, a cash-in-advance constraint and preset wages. Firms must make pro…ts to cover entry costs; thus the markup on goods prices is e¢cient. However, because leisure is not priced at a markup, the consumption-leisure tradeo¤ is distorted. Consequently, the real wage, hours and production are suboptimally low. D...

This paper estimates and simulates a sticky-price dynamic stochastic general-equilibrium model with a financial accelerator, à la Bernanke et al. [Bernanke, B., Gertler, M., Gilchrist, S., 1999. The financial accelerator in a quantitative business cycle framework. In: Handbook of Macroeconomics. North-Holland, Amsterdam], to assess the importance of the financial accelerator mechanism in fittin...

A new approach to the analysis of the effects of monetary policy on economic activity is developing. Its pioneers are Benhabib and Farmer (1992) and Beaudry and Devereux (1993, 1995). The combined assumptions of increasing returns to scale (IRS) in production and sticky prices identify this approach.1 The goal is to rationalize slow price adjustment in response to monetary shocks and, consequen...

This paper examines the implications of on-the-job search for both short-run dynamics of in‡ation and long-run welfare costs of in‡ation in a sticky price model with labour market search frictions. Both unemployed workers and workers with bad jobs can search. Firms can adjust labour at both intensive and extensive margins. On-the-job search gives rise a strong propagation of monetary policy sho...

This paper finds that a model with sticky information is less successful than a standard model featuring nominal rigidities, inflation indexation, and habits in generating the dynamics triggered by technology shocks, as estimated by a vector autoregression using U.S. macroeconomic data. The real wage responses after a permanent increase in productivity clearly favor the standard model. The stic...

I analyze the consequences of including home production in a New Keynesian model with staggered price setting. Home production amplifies responses to technology and monetary policy shocks. Compared to a model without home production, the model generates close to twice the output response to a monetary policy shock. I consider the implications of several nominal interest rate rules and show that...

What accounts for the significant real effects of monetary policy shocks? And what accounts for the persistent and hump shaped responses of output and inflation in response to such shocks? These questions are investigated in a model that incorporates labor market search, habit persistence, sticky prices, and policy inertia. While habit persistence and price stickiness are important for the hump...
