Many papers have reported behavioral biases in belief formation that come on top of standard game-theoretic reasoning. We show that the processes involved depend on the way participants reason about their beliefs. When they think about what everybody else or another "unspeci fied" individual is...

We propose a model of coupled population games where intra- and intergroup interactions overlap. We analyze the general class of symmetric 2x2 games with coupled replicator dynamics. Standard one- and two-population predictions extend to a total of ten regions with different sets of attractors,...

Intensive studies on indirect reciprocity have explored rational assessment rules for maintaining cooperation and several have demonstrated the effects of the stern-judging rule. Uchida and Sasaki demonstrated that the stern-judging rule is not suitable for maintaining cooperative regimes in...

Despite the accumulation of research on indirect reciprocity over the past 30 years and the publication of over 100,000 related papers, there are still many issues to be addressed. Here, we look back on the research that has been done on indirect reciprocity and identify the issues that have...

We study beliefs and choices in a repeated normal-form game. In addition to a baseline treatment with common knowledge of the game structure and feedback about choices in the previous period, we run treatments (i) without feedback about previous play, (ii) with no information about the...

This paper explores three aspects of strategic uncertainty: its relation to risk, predictability of behavior and subjective beliefs of players. In a laboratory experiment we measure subjects? certainty equivalents for three coordination games and one lottery. Behavior in coordination games is...

While shareholders direct influence on management decisions may be small, the takeover threat could serve as an indirect but effective mechanism for shareholders to influence management. We introduce the takeover game, an experimental asset market characterized by two important features: (1)...

Abstract: While shareholders direct influence on management decisions may be small, the takeover threat could serve as an indirect but effective mechanism for shareholders to influence management. We introduce the takeover game, an experimental asset market characterized by two important...

We investigate experimentally the conjecture that loss avoidance solves the tension in stag-hunt games for which payoff dominance and risk dominance make conflicting predictions. Contrary to received textbook wisdom, money-losing outcomes do shift behavior, albeit not strongly, toward the...

Experimental studies of two-person sequential bargaining demonstrate that the concept of subgame perfection is not a reliable point predictor of actual behavior. Alternative explanations argue that 1) fairness influences outcomes and 2) that bargainer expectations matter and are likely not to be...
