The paper reports on experiments designed to compare the performance of two incentive mechanisms in public goods problems. One mechanism rewards and penalizes deviations from the average contribution of the other agents to the public good (tax-subsidy mechanism). Another mechanism allows agents...

A student’s future log-wage is given by the sum of a skill premium and a random personal “ability” term. Students observe only a private, noisy signal of their ability, and universities can condition admission decisions on the results of noisy tests. We assume first that universities are...

This paper addresses the impact of violent conflict on social capital, as measured by citizen anticipation in community groups defined for four activity types: governance, social service, infrastructure development and risk-sharing. Combining household panel data from Indonesia with conflict...

This paper proposes a model which intends to analyse the alternative between discrimination and mutualisation in insurance. We suppose there exists an observable (but initially hidden)variable, that predicts the level of risk of an individual. This variable can be observed through a testing...

This paper provides sufficient conditions for the existence of pure strategy Nash equilibrium in a class of games of group formation. The use of potential allows for a characterisation of such an equilibrium.

This paper constructs an overlapping generations model of pollution externality wherein individuals are altruistically linked to their offspring as in Barro (1974). It is shown that steady state consumption may be a decreasing function of the intergenerational degree of altruism. Despite...

This paper presents an overlapping generations model of environmental externalities with a depollution technology. each agent concerned by the environmental degradation can volutary contribute in order to reduce it. Contributing to the environmental quality means financing depollution activities...

This paper studies within a dynamical model how decentralized individuals happen to elect non-proprietary standard. The issue is coordination because the individual benefit of adoption depends on whether other agents elect to adopt the same standard. It shows that whenthere are increasing...
