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...

We develop a methodology to sign output distortions in the random participation framework. We apply our method to monopoly nonlinear pricing problem, to the regulatory monopoly problem and mainly to the optimal income tax problem. In the latter framework, individuals are heterogeneous across two...

This paper characterizes the optimal redistributive tax schedule in a matching unemployment framework where (voluntary) nonparticipation and (involuntary) unemployment are endogenous. The optimal employment tax rate is given by an inverse employment elasticity rule. This rule depends on the...

This paper characterizes the optimal redistributive tax schedule in a matching unemployment framework with endogenous (voluntary) nonparticipation and (involuntary) unemployment. The optimal employment tax rate is given by an inverse employment elasticity rule. This rule depends on the global...

We show that the domestic output increases with a foreign country's structural reform and decreases with foreign country’s fiscal policy. Hence, when governments act non-cooperatively, they implement too low structural reforms and too much fiscal policies.
