Do marginally admitted public university students earn more than rejected peers?
Core argument: Marginally admitted students at Texas public universities complete an additional year of four-year education, are 12 percentage points more likely to earn a bachelor's degree, and eventually earn 5–10 percent more than marginally rejected but otherwise identical students.
I use administrative admission records spanning all 35 public universities in Texas, which collectively enroll 10 percent of American public university students, to systematically identify and employ decentralized cutoffs in SAT/ACT scores that generate discontinuities in admission and enrollment. The typical marginally admitted student completes an additional year of education in the four-year sector, is 12 percentage points more likely to earn a bachelor's degree, and eventually earns 5-10 percent more than [a] marginally rejected but otherwise identical counterpart. I derive tight bounds on separate effects for students on the extensive margin of the four-year sector versus those who would fall back to a less-preferred four-year school if rejected. These results revealed a dominant role for the extensive margin in driving the average marginal returns.
