The Out-of-State Tuition Distortion
研究了公立大学对非本州学生收取更高学费的福利影响，通过边界断点设计估计了减少学费差距的福利收益。
Public universities typically charge much higher tuition to nonresidents. We first investigate the welfare implications of this tuition gap in a simple model. While the social planner does not distinguish between residents and nonresidents, state governments nonresidents. The welfare gains from reducing the tuition gap can be characterized by a sufficient statistic relating out-of-state enrollment to the tuition gap. We estimate this sufficient statistic via a border discontinuity design using data on the geographic distribution of students by institution.
