In this paper, we suggest a simple sequential mechanism whose subgame perfect equilibria give rise to efficient networks. Moreover, the payoffs received by the agents coincide with their Shapley value in an appropriately defined cooperative game.

In this paper, we consider two classes of economic environments. In the first type, agents are faced with the task of providing local public goods that will benefit some or all of them. In the second type, economic activity takes place via formation of links. Agents need both to both form a...

The model we discuss in this note is a re-examination of the classical Bertrand model of imperfect competition. the main difference is that consumers are allowed to have some strategic behavior when deciding from which one of the two sellers to buy. We will approach the resolution of the...

We investigate experimentally whether preferences over an outcome depend on what other possible outcomes of the situation under consideration are, i.e. whether choices are "menu dependent". In simple sequential games we analyze whether reactions to a certain benchmark oucome are influenced by...

Under not-too-stringent assumptions this study shows that there exists a generic extensive-form game having no "strategically stable" equilibrium. In addition, it is suggested that careless invocation of "common belief assumption" may be a potential source of inconsistent beliefs for players.

We present a new domain of preferences under which the majority relation is always quasi-transitive and thus Condorcet winners always exist. We model situations where a set of individuals must choose one individual in the group. Agents are connected through some relationship that can be...

We propose a definition of egalitarian equivalence that extends Pazner and Schmeidler's (1978) concept to environments with incomplete information. If every feasible allocation rule can be implemented by an incentive compatible mechanism (as, for instance, in the case of non-exclusive...

We consider environments in which agents can cooperate on multiple issues and externalities are present both within and across issues. We propose a way to extend (Shapley) values that have been put forward to deal with externalities within issues to games where there are externalities within and...
