Dustin Gilbreath: Selection bias, matched sampling, and improving second best options in impact evaluation

Monday, March 18, 2019, 5:30 pm – 7:00 pm

While randomized control trials remain the gold-standard in impact evaluation, in many cases they are unlikely to be carried out, whether feasible or not: try to convince the Minister of Infrastructure in your country to put irrigation systems in a random location. To deal with this a variety of silver standard impact evaluation techniques are regularly used. In this talk, Dustin will describe how to improve these at the data collection stage through matched sampling, which has significant advantages in reducing selection bias.
