Price Discrimination and Public Policy in the US College Market
研究了美国联邦政府允许大学使用FAFSA信息进行价格歧视的影响，发现限制该信息会提高学生福利但使部分精英学生被挤出市场。
Abstract In the US, the federal government grants colleges access to a student’s Free Application for Federal Student Aid (FAFSA) which facilitates substantial price discrimination. This article is the first to estimate the consequences of allowing colleges to use the FAFSA in their pricing decisions. I build and estimate a structural model of college pricing and simulate counterfactuals wherein some or all of the FAFSA information is restricted. I find that if FAFSA information were restricted, 13$\%$ of students attending elite colleges would be inefficiently priced out of the elite market. Nevertheless, student welfare would rise as colleges charged the majority of students lower prices. Colleges do use the FAFSA to transfer resources from high- to low-income students on average, but this redistribution is highly imprecise: allowing colleges to use the FAFSA harms one-third of low-income students while one in seven high-income students actually benefit.
