Student Selection into an Income Share Agreement

Financing college expenses through an income share agreement (ISA) is an arrangement where the student agrees to pay a fixed percentage of future earned income for a designated period of time in exchange for college funding. Using administrative and survey data for all eligible applicants to a university ISA program, I estimate the adverse selection into the ISA and provide preliminary estimates of the moral hazard for ISA participants. Identification of adverse selection comes from being able to observe the full set of eligible students who apply to the program. There is evidence of selection on the offered income share rate (which is determined by the student’s major) as well as on parent characteristics, though not parent income. Surprisingly, there is no evidence of adverse selection on student ability as measured by SAT score and college grades. I find no differential selection on other student characteristics including demographics and measures of debt aversion, risk aversion, and time preference. Controlling for observable factors, ISA participation increases the likelihood of college graduation by 3 percentage points and decreases starting salary by $5,000 on average.
