We consider parameterized collections of games without side payments and determine a bound on epsilon so that all sufficiently large games in the collection have non-empty epsilon-cores. The required size of epsilon depends on: (a)the number of approximate player types and the accuracy of this...

In experiments with two-person sequential games we analyze whether responses to favorable and unfavorable actions depend on the elicitation procedure. In our "hot" treatment the second player responds to the first player's observed action while in our "cold" treatment we follow the "strategy...

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...

We introduce the concept of a parameterized collection of games with limited side payments, ruling out large transfers of utility. Under the assumption that the payoff set of the grand coalition is convex, we show that a large game with limited side payments has a non-empty epsilon-core. Our...

This paper studies whether it is possible to characterize an optimal, time-consistent tariff to protect an infant-industry in the presence of learning effects. A domestic monopolist decides how much to produce, taking into account learning effects induced by its current production, while the...

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...

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.
