We study experimentally the outcome of a 50 periods repetition of a two-player coordination game, which admits two-pure strategy Nash equilibria that are Pareto-ranked: a payoff-dominant equilibrium and a risk-dominant equilibrium. The experiment consists of a 2x3 factorial design, with two...

Overcontribution in experiments on voluntary contribution to a public good has not yet received a fully satisfactory explanation. In those experiments, subjects cooperate, in contradiction with the game-theoretic prediction. In contrast, in oligopoly-experiments and common pool resource...

We designed an experiment on voluntary contribution to a public good with interior solution. The treatment variable is the equilibrium level of contribution. We observe that the verage overcontribution rate (cooperation) is affected by the equilibrium level of contribution. Overcontribution is...

We show that experimental subjects tend to contribute more to the public good if they perceive the actions of the others as a source of positive externality rather than a source of negative externality. In our experiment partial contribution to the public good is the unique subgame perfect...

Nous étudions expérimentalement le comportement de sujets confrontés, dans une population, à une multiplicité de jeux du dilemme du prisonnier, suivant que les interactions sont bilatérales ou multilatérales. Nous observons, (i), une coopération significativement supérieure en cas de...

We study the effect of voluntary participation in the context of a collective-good experiment. We investigate whether the freedom to participate in the game or not increases contribution levels and enhances their evolution. The analysis of two voluntary participation treatments supports a...

In Bikhchandani, Hirshleifer, and Welch\'s (1992) specific model, it is showed that conformist behaviors can emerge due to information externalities. In this note we establish that this result, based on `informational cascades\', heavily depends on the choice of a particular tie-breaking...

This paper examines a game-theoretical model of parimutuel betting markets with asymmetric information. Generically, all Bayesian-Nash equilibria of the simultaneous game are characterized depending on the number of bettors and the quality of their private information. An equilibrium where all...

This paper analyzes a model of sequential parimutuel betting described as a two-horse race with a finite number of noise bettors and a finite number of strategic and symmetrically informed bettors. For generic objective probabilities that the favorite wins the race, a unique subgame perfect...

We show that the preference to act as a leader rather than as a follower is related to subjects’ behavioral type. We rely on the methodology proposed by Fischbacher et al. (2001) and Fischbacher and Gächter (2010) in order to identify subjects’ behavioral types. We then link the likelihood...
