Giving with Impure Altruism: Applications to Charity and Ricardian Equivalence
建立了一个不纯利他主义的捐赠模型，假设捐赠者从给予中获得“温暖光辉”，并证明慈善挤出不完全、政府债务有凯恩斯效应，挑战了传统的中性假说。
Models of giving have often been based on altruism. Examples include charity and intergenerational transfers. The literatures on both subjects have centered around neutrality hypotheses: charity is subject to complete crowding out, while intergenerational transfers are subject to Ricardian equivalence. This paper formally develops a model of giving in which altruism is not "pure." In particular, people are assumed to get a "warm glow" from giving. Contrary to the previous literature, this model generates identifiable comparative statics results that show that crowding out of charity is incomplete and that government debt will have Keynesian effects.
