I propose a two-sector endogenous growth model with heterogeneous sectoral productivity and nonlinear hiring costs to analyse the link between sectoral resource allocation, low productivity growth and stagnant real wages. My results suggest that an upward shift in employment, triggered for...

Job polarization is a widely documented phenomenon in developed countries since the 1980s: employment has been shifting from middle to low- and high-income workers, while average wage growth has been slower for middle-income workers than at both extremes. We document 1) that polarization has...

It is common practice to estimate the volatility-growth link by specifying a standard growth equation such that the variance of the error term appears as an explanatory variable in this growth equation. The variance in turn is modelled by a second equation. Hardly any of existing applications of...

This paper adds two-sided ex-ante heterogeneity and a production technology inducing sorting to the canonical Diamond-Mortensen-Pissarides (DMP) search and matching model. Ex-ante heterogeneity and sorting have important implications for the dynamic properties of the model. The modifications...

Standard real business cycle models predict a rise in employment following a technology shock. In contrast, numerous empirical studies show that a technology shock leads to a decline in labor input. In this paper, we demonstrate that a flexible price model enriched with interpersonal comparison...

On the basis of the suggestions of Friedman (1969, 1993) and Moore (1965) and considering the framework proposed by Balke and Wynne (1994, 1995), this paper evaluates whether recoveries growth depends on the characteristics of prior recessions (depth, steepness and duration) in the case of the...

This paper analyzes the effects of short-time work (i.e., government subsidized working time reductions) on unemployment and output fluctuations. The central question is whether short-time work saves jobs in recessions. In our baseline scenario the rule based component of short-time work (i.e.,...

This paper quantifies the impact of the Hartz reforms on matching efficiency, using monthly SOEP gross worker flows (1983-2009). We show that, until the early 2000s, close to 60% of changes in the unemployment rate are due to changes in the inflow rate (job separation). On the contrary, since...

This paper examines the effects of expansionary technology shocks (shocks that increase labor productivity and factor inputs) as opposed to contractionary technology shocks (shocks that increase labor productivity, but decrease factor inputs). We estimate these two shocks jointly based on a...

This paper studies the conditional patterns of unemployment dynamics in Germany. We employ a structural VAR model and identify a technology shock and two policy shocks by using standard restrictions. Interestingly, the worker reallocation process varies substantially with the identified shocks....
