This paper investigates how group membership and competition among trustors interact with trust and trustworthiness in … a laboratory one-shot trust game. To analyze these effects, we apply a 2x2 design. We induce group membership by letting … reduces reciprocity. …

We examine in detail the circumstances under which reciprocity, as defined in Bagwell and Staiger (1999), leads to … fixed world prices. We show that a change of tariffs satisfying reciprocity does not necessarily imply constant world prices … reciprocity and constant world prices, these reforms do not follow from the reciprocity condition, but rather from the requirement …

experimentally investigate the relationship between intrinsic and instrumental reciprocity by running a two-period repeated trust …, and that intrinsic reciprocity is rewarded. In fact, the total level of cooperation, in which trust is reciprocated, is … do not know and hence the second period comes as a surprise. We find that subjects anticipate instrumental reciprocity …
