We provide an elementary proof showing how in economics with an arbitrary number of agents an arbitrary number of public goods and utility functions quasi-linear in money, any efficient and individually rational mechanism is not strategy-proof for any economy satisfying a mild regularity...

The purpose of this paper is to generalize the results obtained by Sklivas (1987) and Fershtman and Judd (1987) allowing for non-linear demand functions, many players and general attitudes to the risk by the players. We also generalize their set-up by introducing a more general measure of th...

In this paper we consider a model of cooperative production in which rational agents have the possibility to engage in sabotage activities that decrease output. It is shown that sabotage depends on the interplay between the degree of congestion, the technology of sabotage, the number of agents...

We analyze how a contest organizer chooses the winner when the contestants.efforts are already exerted and commitment to the use of a given contest success function is not possible. We define the notion of rationalizability in mixed-strategies to capture such a situation. Our approach allows to...

In this paper we study the allocations yielded by kinked demand curves. We will see that there are several difficulties with this concept. Some of them can be eliminated by the consideration of reasonable conjectures

In this paper I analyze the kind of behavior which can be considered evolutively stable in an oligopolistic market
