The three most recent downturns, in contrast with other post-war recessions, are characterized by slow recoveries in employment despite positive economic growth. I find that recent recoveries coincide with high uncertainty about economy-wide corporate profits at a time when output begins to...

Using a dynamic general equilibrium model with many goods and many factors, this paper studies the adjustment process in a transition from one equilibrium to another. Applying a search process, an adjustment technique is developed to link the product and factor markets. Then an optimal control...

Monetary DSGE models are widely used because they fit the data well and they can be used to address important monetary policy questions. We provide a selective review of these developments. Policy analysis with DSGE models requires using data to assign numerical values to model parameters. 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 Keynesian model with its focus on nominal rigidities, and the Diamond-Mortensen-Pissarides model, with its focus on labor market frictions and...

This paper documents the recent changes in the structure and estimation procedures of the SAMBA model, providing a complete description of the decision problems that each economic agent faces, the first order conditions that solve those problems, and the new techniques employed to estimate the...

The holy grail of Keynesian theorists during much of the postwar period has been to fully microfound meaningful wage rigidity (MWR), defined by its capacity to rationally suppress wage recontracting. This paper accomplishes that longstanding goal! MWR is shown to be a necessary condition for the...
