In this paper, we use a Bartik-like approach to identify the effect of increased loan supply on tuition following large policy changes in federal aid program maximums available to undergraduate students that occurred between 2008 and 2010. We construct institution-specific changes in program maximums as the interaction of an institution exposure to the maximums in each aid program (the fraction of qualifying students) and the legislated program maximums. We find that institutions that were most exposed to these maximums ahead of the policy changes experienced disproportionate tuition increases around these changes, with effects of changes in institution-specific program maximums of Pell Grant, subsidized loan, and unsubsidized loan of about 40, 60, and 15 cents on the dollar, respectively.
