We analyze how different previous roles as partners or strangers in public good games affect an individual's subsequent cooperation in a partner setting. We systematically vary a group's composition from all individuals being partner over blended groups of partners and strangers to all...

Lebanon is the country with the highest density of refugees in the world, raising the question of whether the host and refugee populations can cooperate harmoniously. We conduct a lab-in-the-field experiment in Lebanon studying intra- and inter-group behavior of Syrian refugees and Lebanese...

We investigate the effect of a donation incentive tied to contributions to a public good when group members can decide on the size of the donation to be made. An up to 20 % donation of the public good was implemented either exogenously or endogenously by group members. In the Vote treatment,...
