In this paper, a promotion tournament is considered, where, at the beginning of the tournament, it is unknown how long the tournament lasts. Further, the promotion decision is based on the assessments of a supervisor with imperfect recall. In line with psychological research, the supervisor is...

For several years, an increasing number of firms are investing in Open Source Software (OSS). While improvements in such a non-excludable public good cannot be appropriated, companies can benefit indirectly in a complementary proprietary segment. We study this incentive for investment in OSS. In...

In this paper we show how theorems of Borsuk-Ulam and Tucker can be used to construct a consensus-halving: a division of an object into two portions so that each of n people believe the portions are equally split. Moreover, the division takes at most n cuts, which is best possible. This extends...

On the Internet it is easy for someone to obtain a new identity. This introduces opportunities to misbehave without paying reputational consequences. A large degree of cooperation can still emerge, through a convention in which newcomers "pay their dues" by accepting poor treatment from players...

We argue that the rise of antidumping protection and the proliferation of voluntary export restraints are fundamentally inter-related. We show that both can be explained by a cost-based definition of dumping when the domestic government has incomplete information about the foreign firm's costs....

This paper reports on an experiment testing Credible Message Rationalizability (CMR) in one-shot and repeated signaling games with costless communication. CMR is a non-equilibrium theory combining rationalizability with the idea that players will, using the natural meaning of the language,...

Consider a society with a finite number of individuals. A coalition structure is a partition of the set of individuals. Each individual has personal preferences over the set of all coalition structures. We study the strategy proof core and von Neumann and Morgenstern (vN&M) solutions. A roommate...

In this paper we study a large class of non-atomic games arising from interactions on the Internet, such as many users sharing a network link, researchers accessing a database or web server, subscribers to a network services provider trying to gain access to the modem pool and many more. We...

This paper extends theory and experimentation in the context of two parties in a group who contribute to a public good with a provision point. This study analyzes the voluntary contributions game in which a public good is provided if and only if the sum of contributions meets or exceeds a...

This paper describes the results of simulation experiments performed on a suite of learning algorithms. We focus on games in network contexts. These are contexts in which (1) agents have very limited information about the game; users do not know their own (or any other agent's) payoff function,...
