We investigate the conditions under which an inequality averse and additively separable welfarist constitution maker would always choose to set up a progressive equalization payment scheme in a federation with local public goods. A progressive equalization payment scheme is defined as a list of...

We study time-consistent labor and capital income linear taxation using an infinite-horizon overlapping generations model of a small open economy. In dividuals have different productivities and the government intervenes for purely redistributive purposes. The study of time-consistent taxation...

In a model where agents have unequal skills and heterogeneous preferences about consumption goods and leisure, this paper studies how to combine linear commodity taxes and non-linear income tax. It proposes a particular social welfare function on the basis of fairness principles. It then derives...

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...

Xu’s theorem comforts ranking the freedom of choice provided by budget sets as their volume in deriving it from three axioms. Yet, one and a half of these axioms can be discussed. In contrast, simple logic – it seems – leads one to order the freedom provided by budgets sets as the distance...

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...

The aim of this paper is to lay the foundations of a social influence based approach for the diffusion of an innovation or a technological standard.

For more than one decade, Hayek's theory of cultural evolution has been the object of a double controversy, with scientific and philosophical aspects. What is in discussion is nothing less than the existence of inner contradictions in the work of the Austrian Nobel prize winner. Apparently...

The aim of this paper is to set the foundation of an approach of the diffusion-adoption problem of an innovation or a technological standard, based on the building of influence matrixes. This means that agents are to be considered as participating in social networks that provide the support and...
