We study a variant of the repeated Prisoner's Dilemma with uncertain horizon, in which each player chooses his foresight ability: that is, the timing in which he is informed about the realized length of the interaction. In addition, each player has an independent probability to observe the...

Charles Darwin (1874) stated that "women are less selfish but men are more competitive". Very recent papers (Eckel & Grossman, 1998, 2001 or Andreoni and Vesterlund 2001, among others) have shown the relevance of gender in altruism in both ultimatum and dictator games. In this paper we analyze...

Reputation is a commonly cited check on opportunism in economic and social interactions. But it is often unclear what would motivate an agent to report another’s behavior when the pool of potential partners is large and it is easy enough for an aggrieved player to move on. We argue that...

There is by now ample evidence from laboratory experiments that individuals exhibit "prosocial" or "other-regarding" preferences. However, a key question is whether the importance of other-regarding preferences documented in the laboratory can be readily generalized to draw conclusions about the...

We experimentally investigate behavior and beliefs in a sequential prisoner's dilemma. Each subject had to choose an action as first-mover and a conditional action as second-mover. All subjects also had to state their beliefs about others' second-mover choices. We find that subjects' beliefs...

This paper studies the evolution of peoples' models of how other people think - their theories of mind. First, this is formalized within the level-k model, which postulates a hierarchy of types, such that type k plays a k times iterated best response to the uniform distribution. It is found...

We analyze the effect of investments in corporate social responsibility (CSR) on workers' motivation. In our experiment, a gift exchange game variant, CSR is captured by donating a certain share of profits to a charity. We are testing for CSR effects by varying the possible share of profits...

This paper experimentally examines the selection of equilibria in dynamic games. Our baseline treatment is a two-state extension of an indefinitely repeated prisoner's dilemma, which we modify in series of treatments to study the focality of efficiency and symmetry, the effect dynamic and static...

This paper reconsiders evidence from experimental common pool resource games from the perspective of a model of payoff sampling. Despite being parameter-free, the model is able to replicate some striking features of the data, including single-peaked frequency distributions, the persistent use of...
