Private contributions to collective concerns: modelling donor behaviour
非技术性地综述了多种解释自愿捐赠现象的模型，聚焦于捐赠者动机，并讨论了各模型的优缺点，对理解公共物品私人供给有参考价值。
The obvious discrepancy between the predictions of the standard model of private provision of public goods and empirical indications have led many economists to search for alternative explanations of the phenomenon of voluntary contributions. Whilst concentrating on models of donor motivation, the present paper gives a non-technical survey of a sample of these approaches, and discusses their advantages and limitations.
