We develop and estimate a non-stationary job search model to evaluate a scheme that monitors job search effort and sanctions insured unemployed whose effort is deemed insufficient. The model reveals that such schemes provide incentives to the unemployed to front-load search effort prior to...

We introduce different skill groups and production functions into the Burdett-Mortensen equilibrium search model. Supermodularity in the production process leads to a positive intrafirm wage correlation between skill groups. Theory implies that increasing returns to scale can lead to a unimodal...

In this paper we investigate the recent fall in unemployment, and the rise in part-time work, labour market participation, inequality and welfare in Germany. Unemployment fell because the Hartz IV reform induced a large fraction of the long-term unemployed to deregister as jobseekers and appear...

To which extent does an increase in operating effectiveness of public employment agencies on the one hand and a reduction of unemployment benefits on the other reduce unemployment? Using the recent labour market reform in Germany as background we find that the role of unemployment benefit...

In a two-sector-economy with real wage rigidity, we examine how technical progress in one sector affects aggregate unemployment. We show that aggregate unemployment decreases for uneven technical change in the case of Cobb-Douglas production functions. For every type of technical progress there...

For a large set of countries, we document how the labor earnings inequality varies with GDP per capita. As countries get richer, the mean-to-median ratio and the Gini coefficient decline. Yet, this decline masks divergent patterns: while inequality at the top of the earnings distribution falls,...

The total fertility rate is well below its replacement level of 2.1 children in high-income countries. Why do women choose such low fertility levels? We study how labor market frictions affect the fertility of college-educated women. We focus on two frictions: uncertainty created by dual labor...

Imperfect competition in labor markets can lead to efficiency losses and lower aggregate output. In this paper, we study whether differences in competitiveness of labor markets can help explain differences in GDP per capita across countries. We structurally estimate a model of oligopsony with...

We examine wage bargaining when employers and labor unions do not always take all general equilibrium effects into account but learn a steady state. If agents do hardly consider general equilibrium effects, low real wages and low unemployment results. With an intermediate view, when partial...

In this paper we study how promoting product market competition by reducing mark-ups or by increasing productivity are able to complement labor market reforms. We use a simple general equilibrium model with different types of labor. The bottom-line of the paper is that product market reforms...
