Treatment/control randomization is IV

Just a quick follow-up to my prior post on IV. I used a (flawed) treatment/control randomization as an example. My guess is that many people are not aware that the randomization (the coin flip) is an instrumental variable. If this is not clear to you, I highly suggest reading Steve Pizer’s paper on this exact point. His (and my) hope is that it makes IV much more accessible to health services researchers.
