1/ When outsiders enter an academic field, do they create new knowledge? Do newcomers launch new areas of research? New paper by @StephanRisi, me, Emma Kerr, Emer Brady, @lanukim, Daniel A. McFarland, @jurafsky, @james_y_zou and Londa Schiebinger: journals.plos.org/plosone/articl… 🧵

Why do bond prices move so much (and in common)? This puzzle was noticed in 2001 by Collin-Dufresne, Goldstein, and Martin (tinyurl.com/CDGM2001). We take an intermediary asset pricing perspective and show that just 2 dealer factors go a long way towards a resolution. 2/5

WFH saves employees about 70 minutes a day on average. Most (about 60 minutes) from no commute, and the rest (about 10 minutes) from less preparation in the morning. About 1/2 of this saved time goes to working more and 1/2 to leisure/tasks, so employers and employees benefit.

Some non-contradictory things: (1) You can get into an econ PhD without real analysis (2) Those who do have other apparent strengths (3) Doing it will help you get in, ceteris paribus (4) For some people it's useful during the PhD and after; for others it's not

Formal mathematics is a language. Like any language, getting good at writing in it requires practice. Real analysis teaches how to write in that language. Sure, you don't need to know the Hahn-Banach theorem. But you do need to know to write precise theorems/proofs

Honestly if you manage to get in econ PhD without real analysis, you don't plan to do micro theory, and you pass the first year, I'm not even sure you should bother taking real analysis in grad school. You really never use the content after first year outside micro theory

Here’s a fun data point on phd admissions… My Yale class was accidentally emailed the committee’s rankings of all 65 students admitted. So I knew I was #59. It also had a ranking of those on the wait list… Shout out to my good friend who was #65 but also got into Stanford.

So, you got into a PhD program, now what? It depends. This thread, which is based on my own experience and observations, is primarily targeted toward international students but can be useful for local ones as well. [1/n]
