Welcome to this week’s episode of the Mixtape, I’m Scott Cunningham, the host. We are in the final stretch! Season two is almost over. When it’s all said and done, there’ll be 45 episodes in season two, and 34 from season which is [does math on a piece paper, scratches it out, starts over, then announces] 79 episodes. Man, what a fun this has been. Today’s interview is with Dr. Jinyong Hahn, the chair of the economics department at University of California Los Angeles and a prominent econometrical. I knew of Dr. Hahn mainly from his 2001 paper in Econometrica with Petra Todd and Wilbert Van der Klauuw on identification and estimation in regression discontinuity designs though he’s been extremely prolific just that one. I learned a lot of new things, and you’ll hear my surprise as a bunch of things click in place. I just wanted to say again thank you for all your support. I hope you have a great week as we head into the holidays. Scott's Substack is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber.
