Superiority-Seeking and the Preference for Exclusion
研究发现，人们渴望拥有他人想要但得不到的东西，这种动机导致对排斥的偏好，能解释禀赋效应、稀缺性溢价等市场现象，并预测随机排斥买家可提高垄断利润和拍卖收入。
Abstract We propose that a person’s desire to consume an object or possess an attribute increases in how much others want but cannot have it. We term this motive imitative superiority-seeking and show that it generates preferences for exclusion that help explain a host of market anomalies and make novel predictions in a variety of domains. In bilateral exchange, trade becomes more zero-sum, leading to an endowment effect. People’s value of consuming a good increases in its scarcity, which generates a motive for firms and organizations to engage in exclusionary policies. A monopolist producing at constant marginal cost can increase profits by randomly excluding buyers relative to the standard optimal mechanism of posting a common price. In the context of auctions, a seller can extract greater revenues by randomly barring a subset of consumers from bidding. Moreover, such non-price-based exclusion leads to higher revenues than the classic optimal sales mechanism. A series of experiments provides direct support for these predictions. In basic exchange, a person’s willingness to pay for a good increases as more people are explicitly barred from the opportunity to acquire it. In auctions, randomly excluding people from the opportunity to bid substantially increases bids amongst those who retain this option. Consistent with our predictions, exclusion leads to bigger gains in expected revenue than increasing competition through inclusion. Our model of superiority-seeking generates “Veblen effects,” rationalizes attitudes against redistribution and provides a novel motive for social exclusion and discrimination.
