Business cycle models with sticky prices and endegenous firm entry make novel predictions on the transmission of shocks through the extensive margin of investment. This paper tests some of these predictions using a vector autoregression with model-based sign restrictions. We find a positive and...

We characterize optimal monetary policy in a New Keynesian search-and-matching model where multiple-worker firms satisfy demand in the short run by adjusting hours per worker. Imperfect product market competition and search frictions reduce steady state hours per worker below the efficient...

Labor productivity is more procyclical in OECD countries with lower employment volatility. To capture this new stylized fact, we propose a business cycle model with employment adjustment costs, variable hours and labor effort. We show that, in our model with variable effort, greater labor market...

This paper studies the behaviour of firm entry and exit in response to macroeconomic shocks. We formulate a dynamic stochastic general equilibrium model with an endogenous number of producers. From the calibrated model, we derive a minimum set of robust sign restrictions to identify four kinds...

We characterize optimal monetary policy in a New Keynesian search-and-matching model where multiple-worker firms satisfy demand in the short run by adjusting hours per worker. Imperfect product market competition and search frictions reduce steady state hours per worker below the efficient...

The Euro Area is characterized by little variation in unemployment and strongly procyclical labor productivity. We capture both characteristics in a New Keynesian business cycle model with labor search frictions, where labor can vary along three margins: employment, hours, and effort. We...
