The restart effect occurs in linear voluntary contribution mechanism (VCM) experiments when there is an upward pulse in contributions to the group account following a stoppage and then restarting of the VCM experiment. Although the restart effect is a well-known empirical regularity little...

The purpose in this letter is to demonstrate, employing two parametric forms of the Markowitz model of utility, that heterogeneity of preferences of Markowitz agents can contribute towards an explanation of why lotteries typically have multiple rather than single prizes.

We demonstrate theoretically and illustrate the implications of assuming power utility when the true function is of the expo-power form. Empirical results can appear to be consistent with cumulative prospect theory when they are in fact generated from a Markowitz model.

Linear altruism predicts the estimated preferences to be independent of the subject’s position in the game, if the role allocation is randomly determined, because subjects, in each role, have the same preferences ex ante. We test and reject this hypothesis.

We study behavior in the race game with the aim of assessing whether teams can create synergies. The race game has the advantage that the optimal strategy depends neither on beliefs about other players nor on distributional or efficiency concerns. Our results reveal that teams not only...

We provide supporting evidence from the laboratory for the Nash predictions of the homogeneous-good Bertrand model under asymmetric constant unit costs.

Non-governmental organizations and other non-profit organizations attract workers who strongly identify themselves with their missions. We study whether these “good guys” are more trustworthy, and how such pronounced group identities affect trust and trustworthiness within the groups and...

In this paper, we make use of a unique dataset collected at the central train station of the city of Kiel, Germany. Group tickets are used by individual proposers looking for co-travelers to share the ride with shortly before the train departure. The shared ride is offered for a fixed price. We...

We compare dictator and impunity games. In impunity games, responders can reject offers but to no payoff consequence to proposers. Because proposers act under impunity, we should expect the same behavior across games, but experimentally observed behavior varies. Responders indeed exercise the...

We elicit human conditional punishment types by conducting experiments. We find that their punishment decisions to an individual are on average significantly positively proportional to other members’ punishment decisions to that individual.
