DOES PART-WHOLE BIAS EXIST? AN EXPERIMENTAL INVESTIGATION
通过餐厅餐券实验，用激励相容方法测量部分与整体的价值，发现部分价值之和始终大于整体，证实了部分整体偏差的存在，挑战了传统解释。
The existence of part–whole bias has been hotly disputed in the recent contingent valuation literature. This paper reports on an experiment into part–whole bias. Employing vouchers for parts of a restaurant meal and using an incentive compatible procedure, valuations of the parts and of the whole were elicited. The sum of the valuations of the parts consistently exceeded that of the whole, providing evidence of the existence of part–whole bias in a context where traditional explanations would not have predicted it.
