Yesterday I gave a talk on our RDD project at the Centre for Statistical Methodology of the London School of Hygiene and Tropical Medicine. While presenting me, Karla (the organiser of the seminar) joked that I should go for a hat trick of presentations at the LSHTM, since only last month I gave another talk (on the structural zero problems in health economics $-$ on a related note, the paper, which I also discussed here, was actually accepted by Statistics in Medicine).
The main point of this talk was to try and point out various advantages of including genuine prior knowledge in the RDD framework, to try and get suitable estimates and make the assumptions underlying it more robust. I think we need to clarify a couple of points, but also I got good comments, so it was very helpful!
The slides of the talks are here.
