Consider an overlapping generation growth model involving identical countries whose fiscal policy reduces to a pay-as-you-go system with flat rate benefits and uniform payroll tax rate. In autarky, the tax rate is chosen so as to achieve a compromise between intragenerational and...

In this paper we discuss the interest of applying differential co-payment rates across alternative medical treatments. Two treatment strategies are considered: a "long term strategy" in which patients apply preventive measures before knowing if they have the desease and an "emergency strategy"...

The non-cooperative provision of public goods is analysed in the context of a two-stage game in which club size is determined endogenously. Equilibrium club size and voluntary labour supply are shown to be inefficient. The impact of optimally-chosen fiscal policies using simple instruments is...

This paper considers a federal country composed of local jurisdictions which differ in their taste for public goods and finance public spending by a source-based tax on capital income. The taste for public goods is private information of jurisdictions. By transferring differential grants to...

Despite the fact that all developed economies levy broadly-based indirect taxes alongside direct taxes, little theory is devoted to explaining the direct-indirect tax mix. Our purpose is to show that if different taxes have different evasion characteristics, some optimal tax mix emerges...

Most work on tax competition argues that mobile factors tend to be undertaxed except if there is coordination of tax policies. Full coordination is not however always feasible, and as a consequence some measures of partial coordination have been proposed such as minimal witholding taxes on...

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...

An overlapping generations model is constructed in which individual wealth is related to educational attainment, and in which liquidity constraints my induce children to invest in a sub-optimal level of education given their ability. Borrowing for educational attainment is obtained from within...

This paper presents a simple two-country model with mobile capital and immobile labour, in which there are two classes of individuals, the workers and the capital owners. A source-based tax on capital income is used to finance transfers to workers. If the two countries are homogeneous in all...

Most models of tax competition assume full employment. Yet, actually one often observes that fiscal competition, particularly when it is aimed at attracting investment, is motivated by the concern of fighting unemployment and enhancing job creation. The present paper considers a multicountry...
