We find evidence of taste‐based discrimination against rival affiliations in the online market for rental accommodation. Airbnb hosts in college towns increase their listing prices more than hotels on home football games against rival teams. By setting listing prices too high as a result of their affiliation bias against rival fans, hosts experience a 30% reduction in rental income. The overestimation of demand, the cost (inconvenience) of temporary relocation, and the likelihood of incurring damage cannot explain the inverse relation between listing price increases, and rental incomes that is limited to games against rival teams. Instead, greater financial constraints are associated with smaller listing price increases, and higher rental incomes on rival games, suggesting that taste‐based discrimination is a luxury.

租赁住宿在线市场中的会员偏向

我们发现有证据表明在网上租赁住宿市场中存在基于竞争的歧视竞争对手关系的证据。在大学城中，Airbnb房东的房价涨幅超过了与竞争对手进行家庭足球比赛时的酒店房价。由于与竞争对手的粉丝之间存在从属偏见，导致定价过高，房东的租金收入减少了30％。需求的高估，临时搬迁的成本（不便）以及造成损害的可能性无法解释上市价格上涨与租金收入之间的反比关系，而租金收入仅限于与对手球队对战。相反，更大的财务约束与较小的上市价格上涨以及竞争对手游戏的较高租金收入相关，这表明基于口味的歧视是一种奢侈。
