Impressive graph from recent paper by Anne Case and Angus Deaton. Life expectancy in US is less and less a matter of "race", more and more of education. Radical change in just 25 years. Trend is accelerating as population without college education loses years of life expectancy.

John Protzko@JProtzko
Meta-analysis of in-classroom testing effects showed more testing (quizzing) using matching, giving feedback, is good across all school levels, all types of learning, is stronger for post-class quizzing
In short, to maximize learning quiz in class often.

OK, folks. Time for a short thread on a working paper Eddie Kim, @ProfMartyWest and I just released. It's called:
"Kumon In: The Recent, Rapid Rise of Private Tutoring Centers"
The title's cute, but the paper is serious!

José Azar@joseazar
New paper with Xavier Vives: "Revisiting the Anticompetitive Effects of Common Ownership".
While intra-industry common ownership predicts higher prices, inter-industry predicts lower prices.
In airlines, overall effect of the Big Three is lower prices.

Daniel Gottlieb@danielgott
In this issue of Econometrica: "Long-Term Contracting with Time-Inconsistent Agents" with @xingtanzhang
We look at an old question: How do firms contract with present-biased consumers who underestimate their bias?
We give some new answers and a way to think about inefficiency.

Indian jobs have shifted from agriculture to services at a large pace. Does this mean the service sector drove Indian growth, or merely that Indian growth increased demand for services? Fan, Peters, and Zilibotti (2021) try to answer this (nber.org/system/files/w…) 1/

In 2020 we began an initiative @JEEA_News asking authors to submit teaching materials for their accepted articles - these are open access.
As we now have quite a catalogue, we made the teaching materials page searchable by JEL code and issue number.
Enjoy!

After years receiving advice and wisdom by many in the profession, I'm paying it forward by putting together a document with tips for academic research in Economics.
Hope it's useful. I'm curious to hear your reactions. 🧵

Tenure is designed to insulate scholars from risk. The risk of taking on a bold research project that just doesn't work out. The risk of saying something that is politically unpopular but true.
There's one type of risk it can't insulate you from: institutional financial risk.

Gender disparities and monopsony in academic pay: men disproportionately seek/get outside offers, which are matched by retention bonuses, leading to gender pay gaps.
Court rules this is pay discrimination; since all professors are deemed to perform equal work.

U Oregon: Profs are not profs
Appeals Judgment: Profs are profs
The 9th U.S. Circuit Court of Appeals... said plaintiff @jjfreydcourage & 4 male psych profs at the school "share the same overall job" even though the individual tasks they perform vary.

Why are so many great researchers also bad teachers? And why are Econ theory talks often incomprehensible? Growing expertise involves radically recalibrating your pre-formal intuitions, and it’s easy to forget what those intuitions were.
Ethan Mollick @emollick
Why have instructors, rather than experts, teach?
Because research shows that the very nature of being an expert makes it hard to teach your expertise clearly to others. Experts combine so much complex intuition & experience into decisions that is hard to share it. Example 👇😆 https://t.co/EU4DkNcvZL

A thought exercise for #EconTwitter. Which would be easier to explain to a 5-year old:
A) An OLS regression with two-way fixed effects
B) A comparison of means across groups
B) is worlds easier! All the recent probs w/staggered DID are bc we thought A) was doing B) and it's not

Honest Referee Report:
Let me first restate the abstract in different words to assuage any lingering doubts somebody might have that I didn't in fact read the paper.
The paper in fact fine. Like stuff like this gets published all the time. Worse than this in fact.

Analisa Packham@analisapackham
And if you received an interview/flyout and you didn’t get the job, we can still be friends! Rejection does not imply that the committee disliked you.
Ryan Briggs @ryancbriggs
This is good advice. And let me second that if you don’t say anything obnoxious then no one will know or at least remember what you were rejected from. So many people who rejected me for something or other seemingly don’t remember. https://t.co/FSJ053CQ2v
