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.}, organization = {María Paz Espinosa acknowledges financial aid from UPV and MCT (BEC2003- 02084); Pablo Brañas-Garza from DGCYT (SEJ2004-07554/ECON) and GV (GV06/275).}, publisher = {Universidad de Granada.
