Paper summary threads

🚨New Working Paper!🚨
The rise of PE ownership leads to important tradeoffs for news. In joint work with @startupecon and Sabrina Howell, we highlight benefits:
- higher survival
- more digital circulation
and costs:
- less local news
- less employment
- lower civic engagement
NBER @nberpubs
Private equity ownership of newspapers raises digital circulation and survival, but adversely affects local news content, employment, and civic engagement, from @startupecon, @arpitrage, and Sabrina T. Howell https://t.co/73qdP07jNH https://t.co/ALxh6NAd4Z

This is a neat result in @JPubEcon (and I don't think Adam Dearing is on twitter). The paper asks the question: What does a single change in the tax rate allow us to learn about Supply & Demand in a multi-product oligopoly setting? 1/4

Recently published paper in the @JPubEcon :
"Estimating Structural Demand and Supply Models Using Tax Rates as Instruments"

When learning from observations, Bayesian updating is evolutionarily optimal. This is consistent with many non-human animal species’ foraging and reproductive decisions.
But human observational learning deviates from unbiased Bayesian updating in various ways.

Fascinating evolutionary model by our lab's @ptshpark illustrating how our species' reliance on social learning and CREDs might create some of our individual decision-making biases: @mmuthukrishna @robert_t_boyd @rlmcelreath https://t.co/ffdoa8DIgs

@stacylrosenbaum @susan_alberts @ArchieLab & I have a new preprint on a better way to model & test for adaptive developmental plasticity.
Of interest across fields (bio/med/econ/ecol & evol/psych) who test theories of evolutionary adaptation.

This study by @PippaN15 finds that the public's trust in the quality of government is correlated with government's trustworthiness - but only in "open societies".
"But no such relationship is observed in closed societies, where states [control the media]."

1/ Inverse Selection, new paper with @MarkusEconomist and Carlos Segura-Rodriguez.
With the advent of Big Data, AI and Machine Learning, should we think about standard screening models, eg. used for insurance or credit markets, differently?

People viscerally hate inflation while economic models associate small costs to it. @petercoy argues that people should therefore worry less about inflation. But maybe instead models should capture people's sentiments better.
Our model aims to do this: doi.org/10.1093/jeea/j…

Civic engagement systematically declines when the Internet speed rises. Time-consuming activities oriented to the pursuit of collective welfare, suffer the most from broadband penetration, while relationships with family and friends are less affected. buff.ly/3JGmOzh

Want to read an insane tenure denial story? I was denied tenure at MIT in 2018. I was the only Hispanic faculty at my department, had 13k+ citations, 2 books, & papers in Nature, Science, & PNAS. I was never given a reason & the only letter I got told me to check the website./1🧵

“Look Cesar, the truth is that, if you are a mediocre researcher, but your department wants to keep you, they’ll find a way to keep you. And if you are a strong researcher, and your department wants to get rid of you, they’ll find a way to get rid of you.”

Academics/teachers on twitter: what are tips for not losing one's voice while teaching? It happens to me every single time (I guess I tend to shout😬). I am 100%clumsy at sipping a hot beverage while teaching without spilling it all over myself. Is there anything else that helps?
