We explore the evolutionary dynamics of a population that consists of cooperators and defectors, wherein each member of the many pairs of players of a one-shot prisoner's dilemma game is drawn at random, and the number of descendents positively depends on the payoffs in the game. We demonstrate...

This paper examines efficiency rationales behind uniformity of taxation for public projects. Let a benevolent risk neutral 'constitutional designer' to set an optimal cost-sharing rule for a legislature operating under majority rule. Then the designer will choose 'more equal taxes' for a country...

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...

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...

We consider a model where agents differ in their preferences about consumption labor and health, in their (health-dependent) earning ability, and in their health disposition. We study the joint taxation of income and health expenditure, under incentive-compatibility constraints, on the basis of...

When educational policy is supplemented by a redistributive income tax, and when individualsdiffer in their ability to benefit from education, the optimal policy is typically rather regressive.Resources are concentrated on the most able individuals in order to get a "cake" as big aspossible to...

We establish the precise connections between progressive taxation and inequality reduction, in a setting where the level of tax revenue to be raised is endogenously fixed and tax schemes are balanced. We show that, in contrast with the traditional literature on taxation, the equivalence between...
