Entry costs vary dramatically across countries. To assess their impact we construct a model with endogenous entry and operation decisions by …rms and calibrate it to match the U.S. distribution of …firms by size. Higher entry costs lead to greater misallocation of productive factors and lower...

We analyze optimal discretionary monetary policy in an endogenous sticky prices model. Similar models with exogenous sticky prices can deliver multiple equilibria. This is a necessary condition for the occurrence of expectation traps (when private agents' expectations determine the equilibrium...

Entry costs vary dramatically across countries. To assess their impact on cross-country differences in output and TFP, we construct a model with endogenous entry and operation decisions by firms. We calibrate the model to match the U.S. distribution of employment and firms by size. Higher entry...

We reassess convergence of income across countries and its determinants. The ergodic distribution of output per worker features multiple modes. In contrast to previous findings, productivity in the long run is unimodal. The long-run distribution of human capital is multimodal.

Entry costs vary dramatically across countries. To assess their impact we construct a model with endogenous entry and operation decisions by firms and calibrate it to match the U.S. distribution of firms by age and size. Higher entry costs lead to greater misallocation of productive factors and...

A defining feature of business cycles is the comovement of inputs at the sectoral level with aggregate activity. Standard models cannot account for this phenomenon. This paper develops and estimates a two-sector dynamic general equilibrium model that can account for this key regularity. My model...
