Abstract
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 frictions are associated with procyclical labor productivity as well as stable employment. In contrast, the constant-effort model fails to replicate the observed cross-country pattern in the data. By implication, labor market deregulation has a greater effect on the cyclicality of labor productivity and on the relative volatility of employment when effort can vary.

Abstract
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 level. Bargaining results in a convex
