This paper analyzes the emerging literature on the determinants of giving within a social network. We propose two main explanatory variables for previous experimental results on the friendship effect. The first is social integration, which has a positive impact on giving. The second variable is strategic and is based on reciprocity: the possibility of ex-post favors. Econometric analysis shows that both variables play a positive (and significant) role.
