This study explores asymmetric volunteers' dilemma (VOD) games where costs for volunteering is different among players. Diekmann (1993) conjectures that an equilibrium, in which a player with less costs contributes, is more likely to be played if it is risk dominant. We re-examined this...

As one of the best-known examples of the paradox of backward induction, centipede games have prompted a host of studies with various approaches and explanations (McKelvey and Palfrey, 1992; Fey et al., 1996; Nagel and Tang, 1998; Rapoport et al., 2003; Palacios-Huerta and Volij, 2009). Focusing on initial plays...

Theoretical research on leniency programs has so far focused attention on cartels formed within a country the purpose of the paper is to analyze the situation where a cartel is formed internationally. We consider a model with two firms operating in two countries. The antitrust authority (AA) in...

We experimentally examined several versions of Rubinstein (1989)'s e-mail game in the laboratory. He shows that, in the unique equilibrium of this game, players behave as if no information is exchanged, no matter how many messages are successfully sent. This has been regarded as a "paradox of...

We conduct experiments of a cheap-talk game with incomplete information in which one sender type has an incentive to misrepresent her type. Although that Sender type mostly lies in the experiments, the Receiver tends to believe the Sender's messages. This confirms ``truth bias'' reported in...

We present the experimental results of cheap-talk games with private information. We systematically compare various equilibrium refinement theories and bounded rationality models such as level-k analysis in explaining our experimental data. As in the previous literature, we find that when...
