Paper summary threads

Lee Crawfurd@leecrawfurd

New results from a 20-year follow-up on Progresa. Children whose parents received cash transfers in Mexico 20 years ago earn 15% more than those who didn't povertyactionlab.org/sites/default/…

^a lot of good commentary in the replies about fadeout, eg 1, 2

Anna Stansbury@annastansbury

Incredibly striking similarity between US and France in the relationship between parental income and college attendance - and surprising given the massive differences in cost of attending college between the two countries. (new work by @bonneau_cecile & Sebastien Grobon) [1/3]

Thomas Piketty @PikettyLeMonde

Also new on https://t.co/sInc4TxNw1: Unequal access to higher education based on parental income: evidence from France, by C. Bonneau & S. Grobon Bottom line: link btw parental income & access to higher education is almost as strong in France as in the US https://t.co/OMRtHuwcGp https://t.co/eXVyabbypg

A thread on BUE & BLUE🔥 Gauss-Markov condition: 1) y=Xβ+ε 2) E[ε|X]=0 3) Cov(ε|X)=σ^2Σ Standard GM: 4) Σ=I The GM thm shows that OLS/GLS is BL(inear)UE. Hansen (’20) shows it holds for all unbiased est (inc. nonlinear) w/ an elegant proof (tilted density + Cramer-Rao) 1/n

Giuseppe Cavaliere @CavaliereGiu

The OLS estimator is BUE, on top of being BLUE, under classic Gauss-Markov conditions — check out @BruceEHansen’s new amazing #econometrica paper. Textbooks require some updating @jmwooldridge? Question: how much a BUE can depart from linearity? https://t.co/Ci4J5S0vuw

Jeffrey Wooldridge@jmwooldridge

Not exactly. I like Bruce's approach in this paper and it yields nice insights. But in twitter and private exchanges last week, and what I've learned since, it seems that the class of estimators in play in Theorem 5 include only estimators that are linear in Y. #metricstotheface

Borelli @BorelliLuan

It is time for @jmwooldridge to rewrite his books. https://t.co/ltnejZHyzn

Thanks @jondr44! A thread on this short paper 🧵 (no econometric toys are harmed in the writing of this paper)

Jonathan Roth @jondr44

Very cool new paper by @jiafengchen42 that gives a justification for synthetic control methods He shows that when treatment timing is random and you have many time periods, SC has close to optimal regret when an adversary chooses the potential outcomes https://t.co/lD6rpERhfM https://t.co/0rx8L7dIzb

Happy Black History Month- today I want to talk about protests, and specifically whether protests can work to influence economic redistribution using evidence from our newish paper here:researchgate.net/publication/35… 1/n

In a randomised trial with 18k+ participants with suicidal ideation, "training of dialectical behavior therapy skills (mindfulness, mindfulness of current emotion, opposite action, and paced breathing)" raised the risk of self-harm relative to usual care.

Very cool new tinyurl.com/nberp! Losing a job has very different implications across Europe. For Northern Europeans, 5 years after job displacement, earnings are 10% lower than before, while the loss is 3X larger for Southern Europeans (Italy, Portugal, and Spain). 1/3
