We derive a linear-quadratic model that is consistent with sticky prices and search and matching frictions in the labor market. We show that the second-order approximation to the welfare of the representative agent depends on inflation and "gaps" that involve current and lagged unemployment. Our...

Replicating the flexible price allocation in models with nominal rigidities and labor market frictions that lead to an inefficient matching of unemployed workers with job vacancies, even if feasible, is generally not desirable. We characterize the tax instruments that implement the first best...

The canonical new Keynesian Phillips Curve has become a standard component of models designed for monetary policy analysis. However, in the basic new Keynesian model, there is no unemployment, all variation in labor input occurs along the intensive hours margin, and the driving variable for...

We build a business cycle model where employers' screening of heterogeneous workers plays a central role in determining both the flows into and out of unemployment. The model can address how differences between the US and European labor market flows affect business cycle dynamics. It provides a...

In a new Keynesian model with random search in the labor market, endogenous selection among heterogeneous workers amplifies fluctuations in unemployment and results in excess unemployment volatility relative to the efficient allocation. Recessions disproportionately affect lowproductivity...

We explore the distortions in business cycle models arising from inefficiencies in price setting and in the search process matching firms to unemployed workers, and the implications of these distortions for monetary policy. To this end, we characterize the tax instruments that would implement...
