Affiliation bias in the online market for rental accommodation
研究发现Airbnb房东在主场对阵宿敌的橄榄球赛时，会因对对方球迷的偏见而大幅提高挂牌价，导致租金收入减少30%，且这种基于偏好的歧视在财务约束较小的房东中更明显。
Abstract 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.
