Altruism in networks: the effect of connections.
Why are individuals altruistic to their friends? Theory suggests that individual, relationship and network factors will all influence the levels of altruism; but to date, the effects of social network structure have received relatively little attention. The present study uses a novel correlational design to test the prediction that an individual will be more altruistic to friends who are well-c...

This directed altruism effect is complemented by an enforcement effect which increases giving by an additional 25 percent under non-anon...

Directed altruism increases giving to friends by 52 percent relative to rand...
