Notes. Students who chose a federal student loan with IDR against the original ISA contract in the first round (in either of the arms) were presented
with an actuarially equivalent hypothetical ISA contract where they would pay smaller installments over a longer period (2.2% share for 12 years) in
the second round (Panel A). Those who still chose the federal student loan w/ IDR over the longer term ISA contract in the second round were then
given the option to choose between the same student loan w/ IDR and an actuarially equivalent hypothetical ISA contract where they would pay larger
installments over a shorter period (2.8% share for 7 years) (Panel B). Separately, students who chose the original ISA contract (2.3% share for 10
years) against a federal student loan with IDR (in either of the arms) were presented both alternative, actuarially equivalent ISA contracts described
above at the same time. Our results for switching preference to the longer term ISA are presented in Panel C, and results for switching preference to
the shorter term ISA in (Panel D). For further details on how we asked these follow-up questions to the students, please see Figure 4 and Figure 5.
Variable definitions follow the Pre-Analysis Plan. The regression model in all columns is given by Equation 1 in the Pre-Analysis Plan, with the
exception of the dependent variable. The dependent variable takes the value of 1 if the student switched to the alternative contract offered in the
particular round, 0 otherwise. We only report the coefficient of interest, the treatment effect on the likelihood of switching to one of the alternative
ISAs. Except for Model 1, all models include fixed effects for the student’s major. The preferred regression model (Model 7) also controls for (not
reported) age, gender, household size, and highest degree earned. We use log-transformation for current income. N is the sample size.
The sample is the 2,001 students who chose the student loan w/ IDR over the original ISA offer in round one for Panel A; 1,636 students who chose
the federal student loan w/ IDR over in the first round and haven’t switched to the longer term ISA in round two for Panel B; and 775 students who
chose the original ISA over the federal student loan w/ IDR for Panels C and D.
