主题：A Sharp Test for the Judge Leniency Design

讲座简介：

In this paper, we propose a sharp test to assess the validity of the exclusion and monotonicity assumption in judge leniency designs. Our sharp test exploits all the relevant information in the observed data distribution to refute the model and will not make discordant recommendations. When the validity of the design is rejected, we show that a variant of the marginal treatment effect (MTE) can be identified under weaker partial monotonicity and partial exclusion assumptions.
