Testing Social Preferences for an Economic “Bad”: An Artefactual Field Experiment*
通过随机价格投票机制，以大学员工为被试、用蟑螂污染的水作为商品，检验社会偏好是否适用于“坏品”，结果支持Fehr-Schmidt和Charness-Rabin模型，并发现纳入社会偏好能提高多数投票效率。
Abstract We test for social preferences over a commodity in an artefactual field experiment using the random price voting mechanism. Subjects are university staff members, and the commodity is water “contaminated” by a sterilized cockroach. Our results suggest that social preferences exist with respect to commodities and “bads”, supporting a more general utility framework for social preferences. Our empirical test allows for the coexistence of three social‐preference models; our results support the models of Fehr and Schmidt (1999) and Charness and Rabin (2002), but not the model of Bolton and Ockenfels (2000). Also, we find that incorporating social preferences improves the efficiency of majority‐rules voting.
