We study whether a seller’s gender impacts the bargained-for price in a product market, specifically baseball cards. We isolate the seller’s gender using an online transaction exposing the buyer to the seller’s gender via the seller’s hand and name. In both a field experiment, in which we actually sell cards on eBay, and a laboratory experiment, in which we conduct surveys via Amazon Mechanical Turk, we find, contrary to current literature, that women sell baseball cards for a higher price and greater profit compared to men. The observed discrimination appears to be both statistical and taste based. These findings contribute to the law and economics literature on discrimination and have ramifications for the economic opportunities of women in the retail marketplace and for the law of gender discrimination.

在线市场中的性别歧视

我们研究卖家的性别是否会影响产品市场（特别是棒球卡）的讨价还价。我们通过在线交易来隔离卖家的性别，通过卖家的手和姓名将买家暴露给卖家的性别。在实地实验（我们在 eBay 上实际销售棒球卡）和实验室实验（通过 Amazon Mechanical Turk 进行调查）中，我们发现，与现有文献相反，女性以更高的价格和更高的利润出售棒球卡与男性相比。观察到的歧视似乎既是统计上的，也是基于品味的。这些发现为有关歧视的法律和经济学文献做出了贡献，并对零售市场中女性的经济机会和性别歧视法产生了影响。(JEL J16、C91、C93、K31、K38)
