We explore the evolutionary dynamics of a population that consists of cooperators and defectors, wherein each member of the many pairs of players of a one-shot prisoner's dilemma game is drawn at random, and the number of descendents positively depends on the payoffs in the game. We demonstrate...

We endow individuals that differ in skill levels and tastes for working with altruistic preferences for redistribution in a voting model where a unidimensional redistributive parameter is chosen by majority voting in a direct democracy. When altruistic preferences are desert-sensitive, i.e. when...

In a framework of preferences over lotteries, we show that an axiom system consisting of weakened versions of Arrow's axioms has a unique solution. "Relative Utilitarianism" consists of first normalising individual von Neumann-Morgenstern utilities between 0 and 1 and then summing them. This...

We analyse the consequences of an increase of information (say as a consequence of the internet), on the equilibrium of a pure exchange economy with n goods and m agents. We assume that such an increase modifies the characteristics of goods la Lancaster and has a positive effect on utility. We...

The plea bargaining procedure, namely the viability of a stage of bargaining between prosecutor and defendant in criminal suits, is analyzed in the framework of a two-sided incomplete information game. It is shown that, for a given parameter configuration, there exists a Bayesian equilibrium...

This paper identifies the optimal two-period price sequence in the attempt for selling a good, with take-it-or-leave-it offers, when the seller faces ambiguity about the buyers' willingness to pay. If the first round fails, the seller updates its beliefs on the state of the market in accordance...

This paper studies the incidence of tax-transfer policy in a growth model wherein individuals differ according to their level of intergenerational altruism and have an endogenous labor supply. The main results is that public debt is neutral at the macro level but redistributes resources from...

This paper defines a decomposition of technical efficiency for a series of nonparametric deterministic reference technologies related to the Free Disposal Hull. More specificaally, introducing several returns to scale assumptions into this non-convex production model allows one to distinguish...

This paper develops a dynamic model wherein production generates pollution that is viewed as a public bad by consumers. There are two types of consumers : those who are altuist a la Barro-Becker and leave bequests to their children and those who are pure life-cyclers. Both types of consumers...

We develop an overlapping generations growth model in which the individuals care about the environment. Many environmental policies suffer from institutional failures. We focus on the failure resulting from the delegation by the government of the exercise of the environmental policy to an...
