Exiting National Anti-Poverty Campaign, Social Support, and Improved Mental Health

We study the psychological and social impacts of exiting a national anti-poverty campaign, leveraging China's phase-out of its national poverty assistance as a natural experiment. Using a regression discontinuity design, we find that exiting the national campaign improves mental wellbeing. These improvements are accompanied by stronger social and family ties -- such as greater perceived support and communication, while income and material conditions remain largely unchanged. Our findings offer insights into the design of policy exits and underscore the importance of incorporating measures that sustain community- and family-based support systems when implementing or ending assistance programs.

A Way to Synthetic Triple Difference

This paper discusses a practical approach that combines synthetic control with triple difference to address violations of the parallel trends assumption. By transforming triple difference into a DID structure, we can apply synthetic control to a triple-difference framework, enabling more robust estimates when parallel trends are violated across multiple dimensions. The proposed procedure is applied to a real-world dataset to illustrate when and how we should apply this practice, while cautions are presented afterwards. This method contributes to improving causal inference in policy evaluations and offers a valuable tool for researchers dealing with heterogeneous treatment effects across subgroups.
