On Money and Motivation
研究了西弗吉尼亚州PROMISE奖学金项目，发现其通过激励学生达到学业要求而非单纯减轻经济负担来提升学业成绩，对政策制定者和教育管理者有参考价值。
Abstract Programs linking college aid to academic achievement could work either by lowering the cost of college or by inducing additional student effort. I examine the PROMISE program in West Virginia, which offers free tuition to students who maintain a minimum GPA and course load. Using administrative data, I exploit discontinuities in the eligibility formula and the timing of implementation to estimate causal effects. I find robust and significant impacts on key academic outcomes. Impacts are concentrated around the annual requirements for scholarship renewal, suggesting that the program works via incentives for academic achievement, not simply by relaxing financial constraints.
