When incomes are exogenously given, a progressive tax structure reduces inequality in the sense that the Lorenz curve of after tax incomes is nowhere below that of before tax incomes whatever the circumstances as it was shown by U. Jakobsson (Journal of Public Economics 5 (1976), 161-168) The...

This article discusses the properties of Kolm’s ELIE proposal in the Context of optimal income taxation “à la Mirrlees”. It first shows that ELIE gives rise to non-standard type-dependent budget sets, which has important implications in terms of a minimum labour requirement. Second, it...

Simula and Trannoy (2007) have shown that ELIE is confronted with implementation issues when the policymaker cannot observe the time worked by every individual. This paper tries to fix this problem. To this aim, it characterizes the second-best allocations which are the closest to ELIE (i) in...

Restricting attention to quasi-linear utility functions, we examine in the paper the distributive incidence of income taxes used to finance the production of a single public good.

This paper constructs an overlapping generations model of pollution externality wherein individuals are altruistically linked to their offspring as in Barro (1974). It is shown that steady state consumption may be a decreasing function of the intergenerational degree of altruism. Despite...

A l'aide d'un modele a generations imbriquees avec production nous etudions une economie dans laquelle coexistent des agents altruistes et egoistes dont les offres de travail sont endogenes. Nous montrons comment les caracteristiques d'un type d'agent influencent le comportement de l'autre...

Nous considerons un modele dans lequel l'accumulation de capital huamin depend de deux inputs: l'effort prive d'education des individus et le poids du systeme educatif public represente par son taux d'encadrement. Ce dernier depend notamment du pourcentage d'enseignants qui est choisi par les...

This paper examines the consequences of labor immigration in an OLG economy in which agents have an elastic labor supply and differ with respect to degrees of altruism and rates of time preference. It focuses on three substantive questions. First, how do immigrants influence the bequest motive...

This paper on the class of models studiyng the interaction between an altruistic benefactor and a selfish recipient. Bequest is the only transfer from an altruistic parent to his selfish son and we assume that it is not a valid collateral for bank loans. This is equivalent to addding a...
