The distribution of unemployment duration in our equilibrium matching model with spell-dependent unemployment benefits displays a time-varying exit rate. Building on Semi-Markov processes, we translate these exit rates into an expression for the aggregate unemployment rate. Structural estimation...

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...

This paper provides a simple model which explains the choice between permanent and temporary jobs. This model, which incorporates important features of actual employment protection legislations neglected by the economic literature so far, reproduces the main stylized facts about entries into...

The systematic use of experience rating is an original feature of the U.S. unemployment benefit system. In most states, unemployment benefits are financed by taxing firms in proportion to their separations. Experience rating is a way to require employers to contribute to the payment of...

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...

This paper analyzes the consequences of the taxation of temporary jobs recently introduced in several European countries to induce firms to create more open-ended contracts and to increase the duration of jobs. The estimation of a job search and matching model on French data shows that the...

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...

This paper studies the effects of the introduction of unemployment compensation (UC) in countries characterized by pervasive informality. We provide a simple framework to analyze the impact of UC on the allocation of workers between formal and informal activities, as well as the allocation of...

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...

This paper studies the impact of product and labor market regulations on informality and unemployment in a general framework where formal and informal firms are subject to the same externalities, differing only with respect to some parameter values. Both formal and informal firms have monopoly...
