Since the so-called Hartz IV reforms around 2005 and during the global crisis of 2008/2009, the German labor market featured mainly declining unemployment rates. We develop a search and matching model with heterogeneous skills to explore the role of structural and cyclical policies for this...

Since the so-called Hartz IV reforms around 2005 and during the global crisis of 2008/2009, the German labor market featured mainly declining unemployment rates. We develop a search and matching model with heterogeneous skills to explore the role of structural and cyclical policies for this...

We quantitatively assess the role of on-the-job search for labor market dynamics in a fully specified, real DSGE model with endogenous job creation and destruction. The model features heterogeneity of the productivity of firms, across which workers search, as well as heterogeneity of jobs within...

We present and discuss the simple search and matching model of the labor market against the background of developments in modern macroeconomics. We derive a simple representation of the model in a general equilibrium context and how the model can be used to analyze various policy issues in labor...

We demonstrate the possibility of indeterminacy and nonexistence of equilibrium dynamics in a standard business cycle model with search and matching frictions in the labor market. Our results arise for empirically plausible parameterizations and do not rely on a mechanism such as increasing returns.

What are the effects of a higher central bank inflation target on the burden of real public debt? Several recent proposals have suggested that even a moderate increase in the inflation target can have a pronounced effect on real public debt. We consider this question in a New Keynesian model...

We provide an analysis that might help distinguish rationally justified movements in house prices from potentially non-rational movements, using a two-sector business cycle model, in which investment in housing is subject to collateral constraints. A large portion of the evolution of U.S. house...

Since 1991, survey expectations of long-run output growth for the U.S. relative to the rest of the world exhibit a pattern strikingly similar to that of the U.S. current account, and thus also to global imbalances. We show that this finding can to a large extent be rationalized in a two-region...

This paper examines to what extent the build-up of global imbalances since the mid-1990s can be explained in a purely real open-economy DSGE model in which agents' perceptions of long-run growth are based on filtering observed changes in productivity. We show that long-run growth estimates based...

We analyze the implications of intra-firm bargaining for business cycle dynamics in models with large firms and search frictions. Intra-firm bargaining implies a feedback from the marginal revenue product to wage setting, which leads firms to over-hire in order to reduce workers' bargaining...
