This paper proposes a structural non-equilibrium model of initial responses to incompleteinformation games based on "level-k" thinking, which describes behavior in many experiments with complete-information games. We derive the model's implications in firstand second-price auctions with general information structures, compare them to equilibrium and Eyster(More)
". . . professional investment may be likened to those newspaper competitions in which the competitors have to pick out the six prettiest faces from a hundred photographs, the prize being awarded to the competitor whose choice most nearly corresponds to the average preferences of the competitors as a whole; so that each competitor has to pick, not those(More)
"Hide-and-seek" games are zero-sum two-person games in which one player wins by matching the other's decision and the other wins by mismatching. Although such games are often played on cultural or geographic "landscapes" that frame decisions non-neutrally, equilibrium ignores such framing. This paper reconsiders the results of experiments by Rubinstein,(More)
Most applications of game theory assume equilibrium, justified by presuming either that learning will have converged to one, or that equilibrium approximates people’s strategic thinking even when a learning justification is implausible. Yet several recent experimental and empirical studies suggest that people’s initial responses to games often deviate(More)
We investigate whether the gender composition of teams affect their economic performance. We study a large business game, played in groups of three, where each group takes the role of a general manager. There are two parallel competitions, one involving undergraduates and the other involving MBAs. Our analysis shows that teams formed by three women are(More)
This paper compares the leading models of strategic thinking with subjects’ initial responses to Van Huyck, Battalio, and Beil (1990, 1991) coordination games. Among the refined “equilibrium plus noise” models we compare, payoff-dominant equilibrium performs better than risk-dominant or maximin equilibrium. Among the individualistic models we compare,(More)
Affirmative-action policies bias tournament rules in order to provide equal opportunities to a group of competitors who have a disadvantage they cannot be held responsible for. Critics argue that they distort incentives, resulting in lower individual performance, and that the selected pool of tournament winners may be inefficient. In this paper, we study(More)
We use subjects’ actions in modified dictator games to perform a within-subject classification of individuals into four different types of interdependent preferences: Selfish, Social Welfare maximizers, Inequity Averse and Competitive. We elicit beliefs about other subjects’ actions in the same modified dictator games to test how much of the existent(More)
We compare behavior in modified dictator games with and without role uncertainty. Subjects choose between a selfish action, a costly surplus creating action (altruistic behavior) and a costly surplus destroying action (spiteful behavior). While costly surplus creating actions are most frequent under role uncertainty (64%), selfish actions become most(More)
Rubinstein, Tversky, and Heller elicited experimental subjects' initial responses to twoperson constant-sum "Hide-and-Seek" games with unique mixed-strategy equilibria and non-neutral framing of locations. The least focal location was the most prevalent choice for both Hiders and Seekers, and more prevalent for Seekers than Hiders. This robust pattern is(More)
