Altruism and information

Experimental literature has accumulated evidence on the association of personal characteristics to a higher or lower level of prosocial behavior. There is also evidence that donations are affected by the mere provision of information about the recipients, whatever its nature or content. In this paper, we present a unified experimental framework to analyze the impact of social class, political orientation and gender on the level of giving; our experimental design allows us to reveal the effect of providing information by itself, with respect to the baseline treatment of no information, and separately from the effect of the informational content. These results could be relevant to any design intended to measure the impact on altruism of different manipulations of the Dictator Game.
