This paper was a chapter in the book Randomized Control Trials in the Field of Development: A Critical Perspective, a collection of articles on RCTs. Assuming the author of this chapter, Timothy Ogden doesn’t identify as a randomista, the only other author who maybe does is Jonathan Morduch, so it’s a pretty one-sided book (which isn’t necessarily a problem, just something to be aware of).
There was a launch event for the book with talks from Sir Angus Deaton, Agnès Labrousse, Jonathan Morduch, Lant Pritchett and moderated by William Easterly, which you might find interesting if you enjoyed this post.
Ogden works with Innovations for Poverty Action (and, incidentally, is on GiveWell’s board). I’m not sure he’d identify as a randomista but seems very likely he’s favourable to RCTs.
