man resources and finances. While IPEDS is the most comprehensive dataset on postsecondary education available,
because it is based on surveys of administrators, it is not always sufficiently detailed or reliable for our purposes. For
measures of federal aid at the institutional level, we found that the figures contained in the IPEDS ”Student Financial
Aid” survey did not meet our needs for a couple reasons. First, the survey restricts the universe to aid amounts for
”full-time first-time degree-seeking undergraduates,” which is not our student population of interest; second, in part
because of this restriction, the survey has been labeled as the most burdensome of surveys (Government Accountability
Office (2010)); and third, until recently, the survey did not distinguish between federal loans and other loans, and still
does not distinguish between subsidized and unsubsidized loans, which makes our identification more difficult.
Title IV data serve as our primary data source for measuring federal loans and pell grants at the institution level.
While we considered also using IPEDS to obtain these measures, we ultimately found a number of reasons to look to the
Title IV data. One of the reasons is that the IPEDS measures of financial aid are contained in the “Student Financial Aid”
survey, which is considered by most educational administrators to be the most burdensome of the IPEDS surveys (Gov-
ernment Accountability Office (2010)). This is likely because it requires administrators to estimate the total amount of
aid and number of recipients within a specific IPEDS-defined universe of students, ‘’full-time first-time degree-seeking
undergraduates.” Restricting to this universe may be difficult for some institutions depending on what data sources
they pull from to complete the IPEDS surveys. Thus, these data are less reliable than those obtained from the less-
burdensome collection of published tuition levels and enrollment numbers. Second, this universe is not necessarily
representative of the entire undergraduate body. Third, until recently, IPEDS did not distinguish between federal loans
and other loans, and still does not distinguish between subsidized and unsubsidized loans, which makes our identifica-
tion more difficult. We describe the benefits of the Title IV data relative to the IPEDS data in Section 4 in the main body
of the text.
Sample: Our sample begins in the 2000-2001 school year, the first year that the tuition sticker price survey from
IPEDS more or less takes the current form. We end our sample in 2011-2012, since in 2012-2013, changes to graduate
financial aid occur that may interfere with our identification. IPEDS and NPSAS data are reported at institution level
(UNITID), while Title IV is reported at the OPEID level. This is because there may be multiple UNITIDs associated to
one OPEID, as branches (UNITID) of the same institution are sometimes surveyed separately. Our regressions are done
at the OPEID level, where when we are using averages of variables in IPEDS, we take enrollment-weighted averages of
the UNITIDs.
Sticker-Price Tuition: Our main dependent variable is yearly changes in the sticker-price tuition at the institutional
level. This data comes from the IPEDS Student Charges survey. For full academic-year programs, we use the sum of the
out-of-state average tuition for full-time undergraduates and the out-of-state required fees for full-time undergraduates.
For other programs, we use the published tuition and fees for the entire program. For public universitites we use out-
of-state tuition rather than average tuition to abstract from variation driven by changing fractions of in-state versus
out-of-state students. We generally find that the in-state and out-of-state differences are highly correlated.
Enrollment: Enrollment can be measured both as headcount and full-time equivalent students. In general, we use
an IPEDS formula to calculate a full-time-equivalent (FTE) enrollment measure. In certain cases though, we use total
headcounts from the IPEDS enrollment survey, which are available by student level and attendance status.
Federal Loan and Grant Usage: For federal loan and grant totals, we rely on Title IV administrative data rather than
the student financial aid survey from IPEDS, which appears to be somewhat unreliable as it is survey based. Title IV data
contains the number of recipients, and total dollar amount of loans originated or grants disbursed for each institution
and each of subsidized loans, unsubsidized loans, and Pell Grants. We only consider undergraduate policy changes and
tuition in this paper, so we would want these amounts to be for undergraduates only. However, Title IV data does not
break out undergraduate and graduate loans separately until 2011. Pell Grants are only available to undergraduates,
so are not affected. Since imputation of an undergraduate measure requires making several assumptions, our preferred
measure of loan and grant usage at an institution is just the total dollar amount scaled by the FTE count of the university.
We also report results for robustness when we scale the total dollar amount by the total enrollment count. Finally, also
for robustness, we make an attempt to impute an undergraduate measure as follows: Since the maximum subsidized
loan amount changes only for undergraduates in our sample, we assume a constant average graduate loan amount
over time,
¯
g
i
conditional on borrowing. In addition, we assume that the fraction of all subsidized loan borrowers at an
institution who are graduate students also does not change, γ
i
. To calculate
¯
g
i
and γ
i
, we take the averages of the 2011
