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...

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...

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...

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...

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...

L'analyse des durees d'emploi conduit a s'interroger sur l'ajustment entre employeur et employe. Dans ce processus de selection dans l'emplopi se pose le probleme de l'existence d'une heterogeneite individuelle dont la non prise en compte est susceptible d'induire des biais d'estimation. Aussi,...

This paper discusses ways to reduce the bias of consistent estimators that are biased in finite samples. It is necessary only that the bias function, which relates parameter values to bias, should be estimable by computer simulation or by some other method. If so, bias can be reduced or even...
