The role of cognitive ability and personality traits for men and women in gift exchange outcomes
通过礼物交换实验，研究了认知能力和人格特质如何影响男女的工资报价和努力水平，发现认知能力和宜人性对工资和努力有显著正向作用，且忽略这些因素会导致严重偏差。
Abstract We examine the role of cognitive ability and personality traits in a gift exchange experiment. Controlling for cognitive ability and personality characteristics, men offer higher wages than women, and men and women with greater cognitive ability and greater agreeableness on the Big Five personality scale offer higher wages as well. Men provide greater effort than women do, and respond to higher wage rates with greater increases in effort. For both genders, one standard deviation increases in agreeableness and in wages generate similar increases in effort. Serious biases arise from omitting cognitive ability and pooling men and women.
