چکیده

This study focuses on the question whether risk aversion or beliefs of players explain the strategic choices in 2x2 coordination games. In a laboratory experiment we elicit the risk attitudes by using lottery choices. Furthermore, using a quadratic scoring rule, subjects’ beliefs about the choice of the opponent are elicited directly. Our data show that participants’ behavior is not explained by risk attitude, but rather is it best response to their stated first order beliefs. Higher order beliefs follow different patterns which are in most cases in contrast to Bayesian updating. JEL-CLASSIFICATION: D 81, C 91, C 72

Andrea Gallice: Best Responding to What? A Behavioral Approach to One Shot Play in 2x2 Games

We introduce a simple procedure to be used for selecting the strategies most likely to be played by inexperienced agents who interact in one shot 2x2 games. We start with an axiomatic description of a function that may capture players’ beliefs. Various proposals connected with the concept of mixed strategy Nash equilibrium do not match this description. On the other hand minimax regret obeys al...

Does Inequity Aversion Affect Coordination? An Experimental Study

Abundant experimental evidence suggests that many individuals dislike payoff inequities, and this could facilitate coordination in normal-form games where one of the equilibria is more ‘egalitarian’ than the others. In effect, all types of players could converge to that equilibrium, anticipating that the more inequity-averse types will indeed play it. Using a within-subjects design, we study th...

Measuring Strategic Uncertainty in Coordination Games

This paper explores predictability of behavior in coordination games with multiple equilibria. In a laboratory experiment we measure subjects’ certainty equivalents for three coordination games and one lottery. Attitudes towards strategic uncertainty in coordination games are related to risk aversion, experience seeking, gender and age. From the distribution of certainty equivalents among parti...

History as a Coordination Device ∗

Coordination games often have multiple equilibria. The selection of equilibrium raises the question of belief formation: how do players generate beliefs about the behavior of other players? This paper takes the view that the answer lies in history, that is, in the outcomes of similar coordination games played in the past, possibly by other players. We analyze a simple model in which a large pop...
