It’s not joy, but a hypothesis developed by Daniel Batson links empathy and this behavior. James Andreoni explains an “impure” form of this behavior using the “warm glow.” In a paper titled for this behavior, Herbert Simon argues that without this behavior, the paradox of voting would not exist. Ernst Fehr found that an emotionally-driven form of this behavior motivated group members to punish free-riders in a public goods game. Greed aversion, guilt aversion, (15[1])and this behavior are competing explanations for participant offers in the (*) dictator game. Gary Becker argues that this behavior within the family is not fully explained by the evolutionary origin of this behavior via kin selection. Egoism is contrasted with, for 10 points, what cooperative behavior where individuals benefit another’s welfare without benefiting themselves? ■END■
