Here is the dummy test, the easiest test of identification ever: https://t.co/5KgMYEeHlp. If you have bunching on the variable of interest, just add a dummy of the bunching point and test if its coefficient is zero. #EconTwitter #econometrics 1/7

@pedrohcgs @andersen_hecon Please help! UFO is not going to work.

I propose we invent a name for Y_i(0). I, for one, really need a word to refer to this. Please stop me from naming it “placebome” (the placebo potential outcome). #Econometrics

What do you call Y_i(0)? Have we settled on a name? I’ve been calling it “baseline outcome” and “inherent outcome,” but I’m sure there must be a better name. #econmetrics #causalinference

@DSchindlerEcon Only people who have a poor understanding of causal inference hate a method per se in my opinion. Anyway, I suggest this paper by @MC_Knaus

Thread by @jillbarshay about the dangers of over-scheduling kids, followed by the link to her piece about our recent paper. See a thread I wrote about our concerning findings here: https://t.co/bDak6lsKnQ TL;DR: kids are doing too much, and by high school they are not ok.

We are not the first to say this. Psychologists and educators have been saying for a long time that over-scheduling and excessive homework are a problem. We provide solid causal evidence that they are right: https://t.co/UmsSFpKOsh.

Noncognitive skills are built with proper rest and unstructured active pursuits, especially unsupervised play and socialization with peers. Other kids need to also be free for play and socialization to occur.

This is a societal problem. Most enrichment activities are not controlled by parents. Schools assign homework, colleges decide what they will consider in applications. Parents also need to value free play and socialization as the productive activities they are.

Noncognitive skills are often invisible, but are extremely important. They impact future happiness and professional success heavily, sometimes more than the type of knowledge that goes into test performance.

Younger kids seem to be doing better, but that is deceiving. High school kids may be doing worse perhaps exactly because they should have built a larger stock of noncognitive skills in elementary and middle school.

The problem is worse in high school, when kids do much more homework, tutoring and after school lessons while having to keep up other activities that also count towards college applications: sports leagues, instrument classes, volunteering etc.

This is the paper: https://t.co/UmsSFpKOsh. We found that the last hour of enrichment does not help the child’s test scores and hurts the child’s noncognitive skills, causing things like anxiety, depression, low sociability, lack of resilience, etc.

This is a great piece on our recently published work on whether children should do more enrichment activities: https://t.co/xhkuSonhie . The answer is no, children are doing too much, and it’s hurting their ability to emotionally regulate.

Thanks to @IEA_economics for featuring me this month and giving me an opportunity to reflect on my professional journey and to share some of the lessons I Iearnt along the way!

Go Dawgs!!! Spectacular victory! Waking the kids up and heading downtown now #UGAvsTCU #DawgsOnTop

Came back from #ASSA2023 very motivated and grateful! Here's a picture of @agoodmanbacon, Liyang Sun, Brant Callaway, and me, just after we received the @JEconometrics Dennis J Aigner Award for the best empirical paper (our 3 DiD papers shared the award) Thanks a lot!!!

Do you know where the SEA 2023 will be?

I am so happy to see this out in the open! We are finalizing an R package to implement the test in more general cases, including staggered setups. So stay tuned!

I'm so happy that my paper with Brantly Callaway won the Dennis J. Aigner Award at the @JEconometrics. In fact, this is an award for the recent DiD advances, as CS is sharing the prize with 2 other DiD papers that y'all know and love: @agoodmanbacon and Sun and Abraham! Thanks!
