🚨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

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

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.

**Alert**
@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🧵
