Does Instrumental Reciprocity Crowd out Prosocial Behavior?
CESifo, Munich, 2014
CESifo Working Paper No. 5078
In repeated games, it is hard to distinguish true prosocial behavior from strategic instrumental behavior. In particular, a player does not know whether a reciprocal action is intrinsically or instrumentally motivated. In this paper, we experimentally investigate the relationship between intrinsic and instrumental reciprocity by running a two-period repeated trust game. In the ‘strategic treatment’ the subjects know that they will meet twice, while in the ‘non-strategic treatment’ they do not know and hence the second period comes as a surprise. We find that subjects anticipate instrumental reciprocity, and that intrinsic reciprocity is rewarded. In fact, the total level of cooperation, in which trust is reciprocated, is higher in the non-strategic treatment. This indicates that instrumental reciprocity crowds out intrinsic reciprocity: If one takes the repeated game incentives out of the repeated game, one sees more cooperation.
