This paper attempts to provide an explanation for the productivity paradox. We show how this paradox may emerge in oligopolistic markets.

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...

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 note we challenge the non-cooperative foundations of cooperative bargaining solutions on the grounds that the limit operation for approaching a frictionless world is not robusto We show that when discounting almost ceases to play a role, any individually rational payoff can be supported...

In this paper we present a fixprice model in which private and public consumption show some degree of substitution. We offer formulae for the Keynesian multiplier which depend on this degree of substitution. We also show that there is a Pigou effect and that, sometimes, this effect is larger...

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

In this paper we study the conjecture that oligopoly or imperfect competition causes more inflation than perfect competiton. We find necessary and sufficient conditions for this to occur.

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
