This paper addresses the question of the optimal taxation of labour and interest income in an overlapping generations model with two unobservable characteristics, ability and inheritance. We assume realistically that saving can only be taxed anonymously, whereas the tax on labour earnings can be...

Using the standard non linear income and commodity taxation framework, we examine the optimal policy to be adopted when the same labour disutility can receive two opposite interpretations: taste for leisure and activity limitation. In the absence of complete information about individual...

This paper extends an intergenerational context to the prospect of upward mobility hypothesis, showing that the poor majority in democracies may not support massive redistribution for the sake of their children’s educational attainment and upward mobility. We develop an overlapping generations...

This chapter reviews recent theoretical work on the effect of factor mobility and the ensuing tax competition on the capacity of governments to raise revenue and redistribute income. It focuses on three issues: the relevance and limitations of the race to the bottom result, the benefits and...

This paper studies the role of social insurance as a redistributive mechanism in the presence of an optimal (linear or general) income tax. It considers a second-best setting with two unobservable individual characteristics: ability, measured by the wage rate, and risk, measured by the...

Rochet (1989) showed that with distortionary income taxes, social insurance is a desirable redistributive device when risk and ability are negatively correlated. This finding is reexamined when ex post moral hazard and adverse selection are included, and under different informational...
