Endogeneity in Weakly Separable Models without Monotonicity
Songnian Chen, Shakeeb Khan, Xun Tang
We identify and estimate treatment effects when potential outcomes are weakly separable with a binary endogenous treatment. Vytlacil and Yildiz (2007) proposed an identification st…
Parallel Trends and Dynamic Choices
Philip Marx, Elie Tamer, Xun Tang
Difference-in-differences is a common method for estimating treatment effects, and the parallel trends condition is its main identifying assumption: the trend in mean untreated out…
Testable Implications of Multiple Equilibria in Discrete Games with Correlated Types
Aureo de Paula, Xun Tang
We study testable implications of multiple equilibria in discrete games with incomplete information. Unlike de Paula and Tang (2012), we allow the players' private signals to be co…
Identification and Estimation of Weakly Separable Models Without Monotonicity
Songnian Chen, Shakeeb Khan, Xun Tang
We study the identification and estimation of treatment effect parameters in weakly separable models. In their seminal work, Vytlacil and Yildiz (2007) showed how to identify and e…
Estimating Unobserved Individual Heterogeneity Using Pairwise Comparisons
Elena Krasnokutskaya, Kyungchul Song, Xun Tang
We propose a new method for studying environments with unobserved individual heterogeneity. Based on model-implied pairwise inequalities, the method classifies individuals in the s…
