Many experimental studies deal with the comparison of two versions of one game for which agents' behavior is fundamentally different even though the Nash equilibrium is the same. This paper provides a novel approach to explain such findings. It uses the observation that many of these examples...

This paper provides strong evidence supporting the long-standing speculation that decision-making in groups has a dark side, by magnifying the prevalence of anti-social behavior towards outsiders. A large-scale experiment implemented in Slovakia and Uganda (N=2,309) reveals that deciding in a...

This chapter surveys literature on experimental law and economics. Long the domain of legally minded psychologists and criminologists, experimental methods are gaining significant popularity among economists interested in exploring positive and normative aspects of law. Because this literature...

The exogenous manipulation of choice architectures to achieve social ends ('social nudges') can raise problems of effectiveness and ethicality because it favors group outcomes over individual outcomes. One answer is to give individuals control over their nudge ('self-nudge'), but the trade-offs...

We study first- and second-order subjective expectations (beliefs) in strategic decision making. We propose a method to elicit probabilistically both first- and second-order beliefs and apply the method to a Hide-and-Seek experiment. We study the relationship between choice and beliefs in terms...

The centipede game is a two-player finite game of perfect information where a unique subgame perfect Nash equilibrium appears to be intuitively unappealing and descriptively inadequate. This paper analyzes behavior in the centipede game when a traditional game-theoretical assumption that players...

We consider mechanism design in contexts in which agents exhibit bounded depth of reasoning (level k ) instead of rational expectations. We use simple direct mechanisms, in which agents report only first-order beliefs. While level 0 agents are assumed to be truth tellers, level k agents...

The paper proposes a framework to extend regret theory to dynamic contexts. The key idea is to conceive of a dynamic decision problem with regret as an intra-personal game in which the agent forms conjectures about the behaviour of the various counterfactual selves that he could have been. We...

Strategic decisions are affected by beliefs about the expectations of others and their possible decisions. Thus, strategic decisions are influenced by the social context and by beliefs about other actors’ levels of sophistication. The present study investigated whether strategic...

This paper explores the binary choice of an agent who must allocate her attention to noisy information obtained from costly experimentation to improve her knowledge in a context of uncertainty.We model a two period-lived agent who must decide whether to invest or not in each period. Initial...
