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...

In this note we introduce mergers and an endogenous minimum quality standard in a Cournot triopoly with vertically differentiated quality and fixed quality costs. As in Ecchia and Lambertini (1997) we endogenize the choice of the minimum quality standard by allowing the regulator to chose the...

Say has shown that there is no amount of capital which may not be employed in a country. Such a proposal does not involve the absence of unemployment and crisis. The markets may be glutted. In his first writings, Say advanced that whenever there is a superabundance of several sorts of...

This work presents a rationale for the prevalent limits to voters’ information disclosure in electoral settings. When allowed to express an intensity of preferences, strategic voters overstate in equilibrium of large multicandidate elections. Due to these overstatements, the set of voting...

There is some indirect evidence that the absence of markets might cause child labor. However the existing literature is silent on whether marginal improvements of the markets functioning would reduce child labor. This paper models rural households’ labor supply when the degree of imperfections...

We build a theoretical model that incorporates unionization in the labor market into a Heckscher-Ohlin-Samuelson (HOS) framework to in- vestigate the impact of unionization on the Stolper-Samuelson Theorem. To capture the American economy case, we assume that unskilled labor in the manufactured...

Residential location decision is often a household joint decision involving several decision-makers. These different decision-makers usually have diverging preferences, especially in dual-earner households, when spouses work at different locations. Since about half a century, literature on...

The paper considers two-person bargaining under Approval Voting. It first proves the existence of pure strategy equilibria. Then it shows that this bargaining method ensures that both players obtain at least their average and median utility level in equilibrium. Finally it proves that, provided...

While intergenerational transmission of human capital has been widely documented by economists, less is known about differences in schooling between siblings. This paper proposes a measure of educational inequality in France using a sample of 27,197 children from 11,694 families. Estimation of...
