We study the effects of exposure to nonresident students on the outcomes of undergraduate in‐state students during a period of high nonresident enrollment growth at the University of Missouri‐Columbia. Our models leverage within‐major, cross‐time variation in nonresident exposure for identification. We find no evidence that increased exposure to domestic nonresidents affects in‐state student outcomes and our null results are precisely estimated. We find evidence of modest negative impacts on in‐state students when their exposure to foreign students increases using our preferred specification. However, the identifying variation in exposure to foreign students in our data is limited and this result is not robust in all of our models. (JEL I23, I28, R23)

非居民中学后入学增长和本州学生的结业

我们研究了在密苏里-哥伦比亚大学非居民入学人数高速增长的时期内，非居民入学机会对本州本科生结业的影响。我们的模型利用非居民暴露的主要跨时间变化来识别。我们没有证据表明增加与国内非居民的接触会影响本州学生的学习成绩，而我们的无效结果得到了准确的估计。当使用我们的首选规范增加对外国学生的接触时，我们发现对本州学生的负面影响较小。但是，在我们的数据中，对外国学生的暴露程度的识别差异是有限的，并且这个结果在我们所有的模型中都不够可靠。（JEL I23，I28，R23）
