Random taxation may be optimal when the taxpayers differ in their attitudes towards risk, so that tax randomization enables the government to relax the incentive constraints. The paper provides a necessary and sufficient condition for local random deviations to be welfare improving in a...

An optimal contract may involve randomization when the agents differ in their attitudes towards risk, so that randomization enables the principal to relax the incentive constraints. The paper provides a necessary and sufficient condition for local random deviations to be welfare improving in a...

A government designs transfers to agents in the absence of information on their preferences. The second-best allocation is equal sharing among citizens when the awards are deterministic. We provide a necessary and sufficient condition under which lotteries improve upon the egalitarian outcome....

This paper intends to analyze some macroeconomic aspects in the framework of the Optimal Taxation Theory. First of all Optimal Taxation filiation will be considered in studying the three functions of the state described in Musgrave's work. The collective book published in 1994, and entitled...

This paper proposes an experiment about the attitude toward probabilities on a population of portfolio managers. Its aim is to check whether or not portfolio managers are neutral toward probabilities. Meanwhile, it presents a experimental protocole that highlights an inconsistency between two...

This paper analyzes characteristics of the informal economy in Poland in the context of transition, using a specific survey carried out in the framework of the classic Labour Force Survey, conducted by the Polish National Statistical office (GUS), in 1995. The participation probabilities of...

This paper puts forward an explanation of the rapid increase in golden handshake provision in Europe over the last ten years, based on both enhanced investor protection and attractive tax codes for severance pay. This article takes up a framework in which asymmetric information about the quality...

In an overlapping generations economy setup we show that, if individuals can improve their life expectancy by exerting some effort, costly in terms of either resources or utility, the competitive equilibrium steady state differs from the first best steady state. This is due to the fact that...

This paper establishes, in the context of the Diamond (1965) overlapping generations economy with production, that the risk that savings in unbacked assets (like fiat money or public debt) become worthless implies that, not only the first-best steady state, but even the best steady state...

We consider in this paper overlapping generations economies with polution resulting from both consumption and production. The competitive equilibrium steady state is compared to the optimal steady state from the social planner's viewpoint. We show that any competitive equilibrium steady state...
