Cet article montre que dans le cadre d’un modèle d’appariement, la coexistence d’emplois de durées du travail différentes peut s’expliquer par des intensités capitalistiques propres à certaines activités. les firmes sont supposées financer seules le capital nécessaire à la...

This paper is motivated by the recent innovations regarding the taxation of cross-border savings that took place in the European Union and the United States. We develop a model to assess the functioning of the different systems of international taxation used on both sides of the Atlantic Ocean....

This paper analyzes the effects of the marginal tax rate on unemployment and economic efficiency in a matching model with homogenous agents when wages and working hours are bargained over. I show that the theoretical impact of a higher marginal tax rate on unemployment is ambiguous whatever the...

This paper characterizes optimal non-linear income taxation in an economy with a continuum of unobservable productivity levels and endogenous involuntary unemployment due to frictions in the labor markets. Redistributive taxation distorts labor demand and wages. Compared to the laissez-faire,...

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...

The current unemployment insurance and employment protection legislation were set up in an economic environment in which relationships between workers and firms were typically lon-lastingand stable. The increasing globalisation of the economy and the rapid technological and organisational...

Various types of basic income schemes are considered to compensate the allocative inefficiencies induced by unemployment insurance systems. This paper develops a dynamic general equilibrium model of a unionized economy where participation to the labor market is endogenous and the budget of the...

Cet article étudie le rôle redistributif d'une assurance sociale exclusive en présence d'un mécanisme d'imposition directe optimale. Les agents sont caractérisés par une productivité individuelle et un risque maladie. La réalisation de ce risque engendre une dépense de santé ainsi...

We derive a general optimal income tax formula when individuals respond along both the intensive and extensive margins and when income effects can prevail. Individuals are heterogeneous across two dimensions: their skill and their disutility of participation. Preferences over consumption and...
