A new draft of our paper (with John List and @yveszenou1) is out! We exploit variations in spatial exposure to treated neighbors induced by a large-scale field experiment to show how one's neighbors can impact the development of cognitive and non-cognitive skills!

This article uses NIH data to find that scientists are quite unwilling to switch direction in exchange for $ (one s.d. of redirection would take a total of $3.7m-$6.8m in expectation). It does find that those who do switch tend to publish more. aeaweb.org/articles?id=10…

PSA: Your IV estimate is not "ATE on compliers" but some weird weighted average. Read this paper to learn more:

I have a new paper in the Journal of Causal Inference about IVs! You can greatly improve the finite-sample performance of your IV by simply modeling first-stage effect heterogeneity. Super easy! Even if you do a bad job, it helps! Big error reductions. https://t.co/DOSsE6uVfz

Snuck a working paper out at the deadline for a 2020 date 😀 This is a bit different from my normal work, but we’re excited about these new approaches to measuring the ex ante probability financial markets placed on events. Free version on my website! https://t.co/ZYWvn3DxtB

We overlap the territory surrounding the Mediterranean and Black Sea with a grid of 10x10km cell size. Then, we focus on coastal cells and compare those with ancient colonies with similar counterparts where no colonization took place [3/12]

OK folks. Here’s my thread on technology for teaching online.🦠 I’m not an expert, but I’ve got some thoughts. My goal is to cover a few things you might consider if you’re trying to quickly get an existing course online. And my focus is on technology, not pedagogy. 1/ https://t.co/NUUygg0jCi

I argue that it's the place that you can successfully get out of that matters. Not the highest you can get into. You get no job, elite or not, if you don't complete the program. Read my prelim horror story. drive.google.com/file/d/1Tm50KT…
