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 develops a general method to solve the optimal nonlinear income tax model with one action (individual pre-tax income) and multidimensional characteristics. Individuals differ in terms of skills and belong to different groups. A group is a subset of individuals with the same vector of...

This paper studies the optimal income redistribution and optimal monitoring when disabil- ity bene?ts are intended for disabled people but some of the disabled do not claim disability bene?ts and enter the labor force. Classi?cation errors also occur. Some able applicants with high distaste for...

We consider an economy in which agents di¤er in terms of productivity (that may be either high or low) as well as in their preferences for labour. Individuals decide whether or not they enter the labour force. In this context and under asymmetric information, the optimal tax schedules derived...

This paper explores the use of workfare as part of a tax mix when labor supply responses are along the extensive margin. In an economy where the government has a priori chosen any tax-and-bene?t schedule, we show that, despite their common goal of providing additional incentives for individuals...

This note provides a complement to the empirical part of Couprie, Peluso, Trannoy (2009)..It provides a parametric estimate of the intra-household sharing rule using clothes consumption french data.

The paper analyzes the effects of liberalization in increasing returns to scale industries. It studies the optimal regulation of an incumbent competing with an unregulated strategic competitor, when public funds are costly. The model shows a trade off between productive and allocative...

The structure of intra-household allocation is crucial to know whether a transfer from a rich household to a poor one translates into a transfer from a rich individual to a poor one. If rich households are more unequal than poor ones, then a progressive transfer among households reduces...

Political parties compete over income tax functions, and voters vote and decide whether to pay full taxes or to make an e®ort to modify their tax bur- den. We show that political parties only propose e±cient income tax func- tions, in a similar manner to the probabilistic voting theory....

Models of household economics require an understanding of economic interactions in families. Social ties, repetition and reduced strategic uncertainty make social dilemmas in couples a very special case that needs to be empirically studied. In this paper we present results from a large economic...
