我们估计大学质量的影响，使用倾向分数匹配方法和全国青年纵向调查1979年队列。匹配允许我们放松线性函数形式假设隐含在回归离子为基础的估计。我们还研究了支持问题，确定是否有个人参加低质量的大学类似于那些参加高质量的大学，并发现支持条件只持有弱。因此，线性函数形式在基于回归的估计中起着重要的作用（并且匹配估计具有较大的标准误差）。回归和匹配的点估计值对男性来说是相似的，但对女性来说不是。(C)2003 Elsevier B.V.保留所有权利。
We estimate the effects of college quality using propensity score matching methods and the National Longitudinal Survey of Youth 1979 cohort. Matching allows us to relax the linear functional form assumption implicit in regress ion-based estimates. We also examine the support problem by determining whether there are individuals attending low-quality colleges similar to those attending high-quality colleges, and find that the support condition holds only weakly. Thus, the linear functional form plays an important role in regression-based estimates (and matching estimates have large standard errors). Point estimates from regression and matching are similar for men but not women. (C) 2003 Elsevier B.V. All rights reserved.
