It is well known that modern governments are unwilling to use poll taxes because it corresponds to political suicide. Still, poll taxes are allegedly the most efficient form of taxation. Building on Eaton and Rosen (1980) and Peck (1989), the goal of this paper is to show a case where an excise...

This paper deals with the economic and technical impact of the insurance constraint on the optimal insurance contracts. We show that restricting the set of admissible indemnity fucntions to those that do not allow fo indemnities larger than the damage does not invalidate the Pareto-optimality of...

The goal of this study is to develop a tool to aid insurance company adjusters in their decision making and to ensure that they are better equipped to fight fraud.

We discuss the difficult question of measuring the effects of asymmetric information problems on resource allocation. Two of them are retained: moral hazard and adverse selection.

Recent studies do not agree on the possible relationship between medical conditions and traffic safety; most of them do not control for exposure factors. In this study, we estimate the effect of different medical conditions (namely diabetes, high blood pressure, coronary disease and monocular...

In this paper we have proposed a methodology to separate moral hazard from adverse selection.

This paper tests the efficiency associated with the role of memory in long-term contracting. Bonus-malus schemes in automobile insurance are examples of contracts that use memory. During the eighties different contributors (Lambert, 1983, Rogerson, 1985, Boyer, and Dionne, 1989) showed how...
