We study experimentally how (un)selfish lies are reciprocated – or not – in subsequent economic interactions in the labor market. We find that while selfish lies are punished (negative reciprocity), prosocial and altruistic lies are neither punished nor rewarded (lack of positive...

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...

This is the first book that examines the diverse range of experimental methods currently being used in the social sciences, gathering contributions by working economists engaged in experimentation, as well as by a political scientist, psychologists and philosophers of the social sciences. Until...

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 conducted a field experiment on the Internet and investigated the participants' belief updating in an individual learning environment where they observe a sequence of private signals and in a social learning environment where they observe a sequence of other people's actions. We observed that...

In the theoretical assumption of informational cascades, private signals and predecessors' actions are equivalently informative before informational cascades, but are not once informational cascades have started. This experimental study tests this assumption by measuring the informativeness of...
