We examine differences in minority science graduation rates among University of California campuses when racial preferences were in place. Less prepared minorities at higher ranked campuses had lower persistence rates in science and took longer to graduate. We estimate a model of students' college major choice where net returns of a science major differ across campuses and student preparation. We find less prepared minority students at top ranked campuses would have higher science graduation rates had they attended lower ranked campuses. Better matching of science students to universities by preparation and providing information about students' prospects in different major-university combinations could increase minority science graduation.
我们研究了加利福尼亚大学各校区在实施种族偏好政策时少数族裔科学专业毕业率的差异。在排名较高的校区，准备不足的少数族裔在科学专业的坚持率较低，毕业所需时间更长。我们估计了一个学生大学专业选择模型，其中科学专业的净回报因校区和学生准备情况而异。我们发现，在排名靠前的校区中，准备不足的少数族裔学生如果就读于排名较低的校区，其科学专业毕业率会更高。根据准备情况更好地将理科学生与大学匹配，并提供有关学生在不同专业 - 大学组合中的前景信息，可能会提高少数族裔的科学专业毕业率。
