The Generalized Roy Model and the Cost-Benefit Analysis of Social Programs
在广义罗伊模型框架下，非参数地识别了项目参与的成本和净剩余，无需直接成本信息，并应用于估计上大学的毛收益和净剩余。
The literature on treatment effects focuses on gross benefits from program participation. We extend this literature by developing conditions under which it is possible to identify parameters measuring the cost and net surplus from program participation. Using the generalized Roy model, we nonparametrically identify the cost, benefit, and net surplus of selection into treatment without requiring the analyst to have direct information on the cost. We apply our methodology to estimate the gross benefit and net surplus of attending college.
