Also published as Working Paper DFAEII 2009-05 and as an article in: Games and Economic Behavior, 2010, vol. 69, issue 2, pages 249-257. We report on a two-stage experiment in which i) we first elicit the social network within a section of undergraduate students and ii) we then measure their altruistic attitudes by means of a standard Dictator game. We observe that more socially integrated subjects are also more altruistic, as betweenness centrality and reciprocal degree are positively correlated with the level of giving, even after controlling for framing and social distance, which have been shown to significantly affect giving in previous studies. Our findings suggest that social distance and social integration are complementary determinants of altruistic behavior.
