The Atkinson-Stiglitz Theorem shows that with weakly separable preferences, differential commod- ity taxes are not needed if an optimal nonlinear income tax is imposed. Redistributive objectives can be achieved with the income tax alone even if goods differ considerably in their income...

This paper studies the normative problem of redistribution among individuals who can influence their longevity through a non-monetary effort but have different taste for effort. As benchmarks, we first present the laissez-faire and the first best. In the first best, the level of effort is always...

This paper tackles the issue of international fiscal coordination in a world of integrated markets sovereign national governments. Taxation of mobile capital and immobile labor in order to finance a public good generates inefficient fiscal competition. Two fiscal reforms are considered: a...

This paper provides a model of nonlinear income taxation in a context of international mobility. We consider two identical countries, in which each government chooses non-cooperatively redistributive taxes. It is shown that when skilled workers can move at low cost, the income taxation does not...

This paper studies how congestion in the public health sector can be used as a redistributive tool. In our model, agents differ in income and they can obtain a health service either from a congested public hospital or from a non congested private one at a higher price. With pure in-kind...

In this paper, we analyse tax harmonisation in the framework of two countries asymmetric in their capital-labour endowment. In the first part, countries play a non-cooperative game and we examine how na- tional fiscal policies are decided according to majority voting. At the Nash equilibrium,...

We study the political economy of social insurance in a world where individuals differ in both income and risk. Social insurance is financed through distortionary taxation and redistributes across income and risk. Individuals vote on social insurance which they can complement with insurance...

This paper presents a political economy approach to payroll tax competition between countries adopting different systems of social insurance. It considers two such systems: the Bismarckian one where benefits are partially linked to payroll taxes and the Beveridgean one where benefits are fiat. A...

It is well known that, in OLG economies with life-cycle saving and exogenous growth, competitive equilibria will in general fail to achieve optimality and may even be dynamically inefficient. This is a consequence of individuals accumulating amounts of physical capital that differ from the level...

In this paper we explore the consequences for optimality of a social planner adopting two different welfare criteria. The framework of analysis is an OLG model with physical and human capital. We first show that, when the SWF is a discounted sum of individual utilities defined over consumption...
