Our aim is to explain why the pattern of relative unemployment rates by education groups was non monotonic in most of the OECD countries. In a two-sector matching model, a simple unexpected productivity shock biased against unskilled labor can replicate the observed dynamics. Effects of...

We consider the search behaviour of an infinite lifetime worker whose expected matching gains are assumed to be decreasing over the spell of unemployment. The search effort is linked positively to future earnings and negatively to the worker's reservation wage. We show that this may give rise to...

We compute transition rates from unemployment by means of a model that permits a double perspective. First we use a nonstationnary structural job search model, in order to distinguish the agent's strategy from his environment. Secondly, we direct the study towards a skill analysis. Finally, we...

We investigate the existence conditions of involuntary unemployment in an overlapping generations model with an imperfect output market. At the temporary equilibrium, unemployment is involuntary if it exists whatever the nominal wage. The study of the price-elasticity components gives us two...

Management and a union bargain sequentilally, first choosing a contract which will later determine the level of employment, and then choosing a wage. The government then chooses an output subsidy, after which the industry chooses employment according to the contract. The presence of a natural...

Most of the literature on unemployment benefits assumes that they are detrimental to the search effort. However, search is costly and the unemployment are largely finance-constrained. We here consider that search intensity depends on the financial spendings of the worker.

This is a study in the field of unemployment and unemployability. I build an unclosed matching model of unemployment, where matching rates are exogenous. The value of an unfilled job depends on the average skill of the unemployed, who are supposed to lose (absolutely, or relatively) some of...

In order to increase skilled labour, governments manipulate the quantity and the quality of students. This paper investigates both dynamical and steady state responses of such a shock in a model of matching frictions with both skilled and unskilled agents. A less selective educationpolicy leads...
