We analyze optimal taxation in an economy with monopsonistic labor markets. Theindividuals, whose only decisions are whether to work, or not, have heterogeneousproductivities and opportunity costs of work. Given its preferences for redistribution, thegovernment, which does not observe the...

There has been little empirical work evaluating the sensitivity of fertility to financial incentives at the household level. We put forward an identification strategy that relies on the fact that variation of wages induces variation in benefits and tax credits among "comparable households...

We assess the usefulness of stochastic redistribution among a continuum of risk-averse agents with quasilinear utilities in labor. Agents differ according to their consumption tastes, which remain private information. We identify circumstances where stochastic redistribution is socially...

In a second best environment, the optimal policy choice sometimes follows the first best rules. This note lays down the information structure and separability assumptions under which this property holds in a variety of setups.

Heterogeneity is likely to be an important determinant of the shape of optimal tax schemes. This article addresses the issue in a model à la Mirrlees with a continuum of agents. The agents differ in their productivities and opportunity costs of work, but their labor supplies depend only on a...

This paper documents the key stylised facts underlying the evolution of labour supply at the extensive and intensive margins in the last forty years in three countries: United-States, United-Kingdom and France. We develop a statistical decomposition that provides bounds on changes at the...

We study optimal taxation in the general extensive model: the only decision of the participants in the economy is to choose between working (full time) or staying inactive. People differ in their productivities and in other features which determine their work opportunity costs. The qualitative...
