I am teaching a program evaluation and data analysis course where I would like to have the students replicate a study that uses differences-in-differences. For some other study methods, I was able to find papers from AEJ: Policy or AEJ: Applied with replication data they can use, but I didn't find a paper that exactly suits my purposes for diff-in-diff.
Any suggestions on papers that use diff-in-diff that have posted their data? Bonus points if the paper is on an education topic.
