Credit Supply and the Rise in College Tuition: Evidence from the Expansion in Federal Student Aid Programs
研究了过去15年学生信贷扩张与大学学费上涨的关系，发现联邦学生贷款上限提高导致学费上涨，补贴贷款每增加1美元学费上涨约60美分，非补贴贷款每增加1美元学费上涨约20美分。
We study the link between the student credit expansion of the past 15 years and the contemporaneous rise in college tuition. To disentangle simultaneity issues, we analyze the effects of increases in federal student loan caps using detailed student-level financial data. We find a pass-through effect on tuition of changes in subsidized loan maximums of about 60 cents on the dollar and of about 20 cents on the dollar for unsubsidized federal loans. The effect is most pronounced for more expensive degrees and degrees offered by for-profit and 2-year institutions. Received February 23, 2017; editorial decision March 8, 2018 by Editor Wei Jiang.
