Award displacement occurs when one type of financial aid award directly contributes to the change in the quantity of another award. We explore whether postsecondary institutions displaced awards in response to the Pittsburgh Promise scholarship by capitalizing on the doubling of the maximum Promise amount in 2012. We use de-identified student-level data on each Promise recipient's actual cost of attendance, grants, and scholarships, as well as demographic and academic characteristics from school district administrative files to examine whether and how components of students’ financial aid packages and total costs of attendance changed after the Promise award increase. To account for overall trends in pricing and financial aid, we compare Promise recipients to the average first-time, full-time freshman entering the same institutions in the same year as reported by the Integrated Postsecondary Education Data System (IPEDS). With these two data sources, we assess differences in costs and awards between Promise students and their peers, on average, and examine whether and in what ways these differences changed after the increase in Promise funding. We refer to this strategy as a “quasi-difference-in-differences” design. We do not find evidence that institutions are responding to the Promise increase through aid reductions.

加减法：私人奖学金是否会导致经济援助被取代？

当一种经济援助奖励直接导致另一种奖励数量的变化时，就会发生奖励转移。我们利用 2012 年最大承诺金额翻倍的机会，探讨高等教育机构是否会因匹兹堡承诺奖学金而取代奖学金。我们使用去识别化的学生级别数据，了解每个承诺接受者的实际就学费用、助学金和奖学金，以及学区行政档案中的人口和学术特征，以检查在承诺奖增加后，学生的经济援助计划的组成部分和就学总费用是否以及如何变化。为了考虑定价和经济援助的总体趋势，我们将承诺接受者与综合高等教育数据系统 (IPEDS) 报告的同年进入同一机构的首次全日制新生平均水平进行比较。通过这两个数据源，我们评估了 Promise 学生与同龄人之间的平均成本和奖励差异，并检查这些差异在 Promise 资助增加后是否以及以何种方式发生变化。我们将这种策略称为“准差异中的差异”设计。我们没有发现任何证据表明各机构通过减少援助来应对承诺的增加。
