摘要

In this paper, an economy is analyzed where one group of agents, the altruists, cares about the wellbeing of another group of agents, the recipients. it is asked how changes in the size of these groups affect the altruists' charitable giving in the Nash equilibrium. I show that a pure group size effect, i.e., a proportional expansion of both subgroups can lead to less free riding and to a lower degree of underprovision relative to the efficient level of charitable giving.
