The Economic Impact of Access to Public Four-Year Colleges
利用断点回归估计美国佐治亚州高中生进入公立四年制大学对30岁左右家庭收入的影响，发现收入提升约17%，对低收入高中学生影响更大，但对财务健康或学生贷款余额影响不大。
<h3>Abstract</h3> We estimate the economic impacts of students' access to an entire sector of U.S. public higher education. Approximately half of Georgia high school graduates who enroll in college do so in the state's public four-year sector, which requires minimum SAT scores for admission. Regression discontinuity estimates show enrollment in public four-year institutions boosts students' estimated household income around age 30 by about 17 percent and has even larger impacts for those from low-income high schools. Access to this sector has little clear impact on financial health or student loan balances. For the marginal student, and particularly for those from low-income high schools, enrollment in such institutions has large private returns in the short run and positive returns to state budgets in the long run.
