Departures from pure self interest in economic experiments have recently inspired models of "social preferences". We conduct experiments on simple two-person and three-person games with binary choices that test these theories more directly than the array of games conventionally considered. Our...

This paper explores the effect of the possibility of third-party intervention on behavior in a variant of the Berg, Dickhaut, and McCabe (1995) “Investment Game”. A third-party’s material payoff is not affected by the decisions made by the other participants, but this person may choose to...

Previous indirect evidence suggests that impulses towards pro-social behavior are diminished when an external authority is responsible for an outcome. The responsibility-alleviation effect states that a shift of responsibility to an external authority dampens internal impulses toward honesty,...

We examine, experimentally and theoretically, how communication within a partnership may mitigate the problem (highlighted in contract theory) of hidden action. What is the form and content of the communication? Which model of decision-making can capture the impact of communication? We consider...

Departures from self-interest in economic experiments have recently inspired models of "social preferences". We design a range of simple experimental games that test these theories more directly than existing experiments. Our experiments show that subjects are more concerned with increasing...

Some current utility models presume that people are concerned with their relative standing in a reference group. If this is true, do certain types care more about this than others? Using simple binary decisions and self-reported happiness, we investigate both the prevalence of ``difference...

It is traditional in experimental games to allow participants to choose only actions or possibly communicate intended play. In sequential two-person games, we require first movers to express a preference between responder choices. We find that responder behavior differs substantially according...

We test whether promises per se are effective in enhancing cooperative behavior in a form of a trust game. In Charness & Dufwenberg (2006) we found considerable effectiveness for free-form personalized pre-play statements-of-intent ("promises"), in support of a theory of belief-dependent guilt...
