Endogenous censoring in the mixed proportional hazard model with an application to optimal unemployment insurance
研究了混合比例风险模型中删失机制假设对估计结果的影响，允许删失与个体特征相关，并用矩不等式刻画识别集，最后估计了失业救济金对失业退出率的弹性并评估福利后果。
Summary We examine the sensitivity of estimates of the MPH model with respect to assumptions on the censoring mechanism in the context of an economic model of optimal unemployment insurance. We assume a parametric model for the duration of interest and leave the distribution of censoring unrestricted, allowing it to be correlated with observed and unobserved characteristics. We provide a practical characterization of the identified set with moment inequalities and suggest methods for estimating this set. We apply this approach to estimate the elasticity of unemployment exit rate with respect to unemployment benefit. Finally, we investigate welfare consequences of our estimates.
