Young, Selfish and Male: Field Evidence of Social Preferences
通过三个现场实验（市场公共品博弈、大学募捐、电视游戏节目）研究社会偏好，发现年龄与社会偏好存在关联。
This study examines social preferences in three distinct field environments. In the first field setting, I allow consumers of all age and education levels to participate in one-shot and multiple-shot public goods games in a well-functioning marketplace. The second field study, an actual university capital campaign, gathers data from mail solicitations sent to 2, 000 Central Florida residents. In the third field experiment, I examine data from an uncontrolled environment, a television gameshow, which closely resembles the classic prisoner's dilemma game. Several insights emerge; perhaps the most provocative is that age and social preferences appear linked. Copyright 2004 Royal Economic Society.
