Impact de l'assurance chômage et de l'assistance chômage sur le chômage d'équilibre

In this paper, I build a wage bargaining model to study the consequences of unemployment insurance and unemployment assistance on unemployment. I show that indexing the unemployment insurance benefit on the last wage earned increase the level of unemployment. I describe necessary conditions to avoid unemployment benefits to affect the level of unemployment. At last, we show that the effect of unemployment insurance on the unemployment rate depends on the concavity of the utility function.
