How private is private information? The ability to spot deception in an economic game
通过买方-卖方博弈实验，研究人们在面对面交易中识别欺骗的能力，发现买家预测准确率高于随机水平，且自信的买家表现更佳，信息不对称因此部分消除。
We provide experimental evidence on the ability to detect deceit in a buyer-seller game with asymmetric information. Sellers have private information about the value of a good and sometimes have incentives to mislead buyers. We examine if buyers can spot deception in face-to-face encounters. We vary whether buyers can interrogate the seller and the contextual richness. The buyers' prediction accuracy is above chance, and is substantial for confident buyers. There is no evidence that the option to interrogate is important and only weak support that contextual richness matters. These results show that the information asymmetry is partly eliminated by people's ability to spot deception.
