I used to be saddened to listen to of Chris Sims’s passing yesterday. Though I’m not a macroeconometrician, his work has strongly influenced the best way I take into consideration econometrics. I coated his well-known helicopter tour paper on this weblog some time again. A few of my different favorites are unpublished notes or slides from his web site, a lot of them with a philosophical bent. Excited about instrumental variables is a paper I learn in grad college that actually clarified why issues can go so badly incorrect in IV estimation. I learn Understanding Non-Bayesians for the primary time a few years in the past and wished I had learn it sooner. It articulates a view of Bayesian econometrics that I discover notably compelling. Robins-Wasserman, Spherical N and Sharp Econometrics have additionally formed the method I’m taking in some latest work with Laura Liu.
I didn’t know Chris effectively, however I met him a few occasions early in my profession. A type of conferences is especially memorable. I used to be invited to offer a seminar at Princeton on comparatively brief discover and was feeling apprehensive. The fabric that I had able to current was preliminary and a bit uncommon: it included components of my paper on disciplining beliefs in addition to some extra conventional outcomes that ultimately made their manner into this paper.
Once I noticed that my first assembly of the day was with a Nobel laureate whom I’d by no means met earlier than, I used to be much more nervous! However Chris was nice; inside a few minutes I felt fully snug speaking with him and was genuinely stunned to see how he was in listening to my views on econometrics. I don’t imply to say that my views have been notably insightful or fascinating. I feel Chris simply genuinely loved partaking with folks about econometrics and puzzling by the problems that he discovered fascinating and vital.
Close to the start of my seminar, somebody within the viewers requested me a barely pointed query—not impolite however positively skeptical of my method. For no matter cause, I obtained flustered and flubbed my response. I couldn’t appear to articulate my level, after which bungled my response to a follow-up query as effectively. Simply after I began to fret that my seminar was going off the rails, Chris chimed in and clarified the purpose I had been struggling to articulate. I keep in mind feeling extremely relieved, like somebody had simply pressed a reset button for my speak. It was only a small factor, but it surely meant loads to me at a time in my profession after I was feeling something however assured about my concepts and my work.
