DIFFERENCE IN DIFFERENCE FOR HEALTH ECONOMICS POW 2/?

Paper of the week (POW) this week goes to "Designing Difference in Difference Studies: Best Practices for Public Health Policy Research" by Coady Wing and coauthors published in the Annual Review of Public Health. 

​

It contains a lot of useful reminders on best practices for empirical strategies that rely on difference-in-difference estimators.

Very helpful! Used it this morning in exploring some preliminary results.
