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.

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 note exhibits sufficient conditions concerning the skills of old workers ruling out overaccumulation stationnary equilibria in an OLG model with productive capital.

We modify the altruistic model by assuming that income, instead of the heir's utility, enters the altruist's utility function. We name this formulation "myopic" because, unlike in Barro's (1974) model, the altruist does not need to foresee into the indenite future to make his decisions. We...

We construct a R&D based endogenous growth model within an overlapping generations framework. We study the properties of the long run growth rate. We define endogenous growth as an equilibrium in which the long run growth rate is always stricly larger than zero. Then, we show that endogenous...

Ce papier presente un modele d'equilibre general de concurrence imparfaite dans une economie d'echange avec generations imbriquees. La concurrence imparfaite se traduit par la regle de fixation du prix des jeux strategiques du marche a la Shapley-shubik. Apres avoir presente le modele et defini...

We consider the determinacy of perfect foresight equilibrium near a steady state in an overlapping generations model with production and both altruistic and non altruistic agents having distinct utility functions. The proportions of each type of consumers is exogenously given. Such a model may...

This paper shows that Barro's (1974) debt neutrliaty theorem does not hold in OLG economies whenever the marginal rate of substitution between both periods' consumptions evaluated at the modified golden rule capital stock is lower that the degree of intergenerational altruism. It could be...
