推荐用渐进(多期)DID和事件研究法开展政策评估的论文及其实现数据和代码！

今天，分享一份使用渐进（多期）DID和事件研究法开展政策评估的论文及其实现数据和代码。这样，各位中青年学者就可以直接根据代码操作多期DID的实现过程，而对于在理解上存在困难的可以对照文中的解释予以理解。之前，我们也有推荐过其他关于DID的代码和数据，社群里提供了下载方式。

Tamara McGavock,Here waits the bride? The effect of Ethiopia's child marriage law, Journal of Development Economics, Volume 149, 2021, 102580,https://doi.org/10.1016/j.jdeveco.2020.102580.

Abstract: Child marriage is still common in the developing world: in 2012, one in three women was married by age 18, with more than 10% married before age 15. Beginning in 2000, Ethiopia's semi-autonomous regions raised the legal minimum age of marriage from 15 to 18. This study leverages the natural experiment arising from the staggered roll out of the policy in a difference-in-differences and event study framework. The results suggest that the reform delayed women's marriage, and in particular delayed marriages of girls under 16 by about 17 percent (6.8 percentage points) in areas where early marriage was more common prior to the reform. However, the effect of the reform, though larger, is insignificant among women belonging to ethnic groups with the strongest norms toward early marriage. Women's fertility was delayed and may be lower over their lifetimes.
