Shaping beliefs in experimental markets for expert services: Guilt aversion and the impact of promises and money-burning options
在专家与消费者的信任品博弈实验中，研究了非约束性承诺和消费者烧钱选项对专家行为的影响，发现承诺能促使专家更友好，但烧钱选项无效。
In a credence goods game with an expert and a consumer, we study experimentally the impact of two devices that are predicted to induce consumer-friendly behavior if the expert has a propensity to feel guilty when he believes that he violates the consumer's payoff expectations: (i) an opportunity for the expert to make a non-binding promise; and (ii) an opportunity for the consumer to burn money. In belief-based guilt aversion theory the first opportunity shapes an expert's behavior if an appropriate promise is made and if it is expected to be believed by the consumer; by contrast, the second opportunity might change behavior even though this option is never used along the predicted path. Experimental results confirm the behavioral relevance of (i) but fail to confirm (ii).
