Does Uber Benefit Travelers by Price Discrimination?
利用洛杉矶、纽约和旧金山机场到酒店的优步行程数据，检验优步是否根据酒店价格对乘客实行三级价格歧视，并发现价格歧视平均提高了乘客福利。
We use Uber fare data for passenger trips from Los Angeles, New York, and San Francisco airports to hotels in those metropolitan areas to test whether Uber engages in third-degree price discrimination by charging higher fares to travelers who originate from the same airports as other travelers but who stay at more expensive hotels. We find that fares are positively and statistically significantly related to the price of hotel rooms. Importantly, we also find that allowing ride-sharing companies to price discriminate improves travelers’ welfare, on average, by increasing their travel options.
