My JMP asks a classic question:
Do large, dominant firms foster or hinder innovation?
To study this, I turn to the Great Merger Wave (1895–1904), when >2,600 U.S. firms combined into corporate giants like U.S. Steel and DuPont.

This paper’s been popping as “evidence” that you can’t do real #causalinference w/ obs data. To me it shows you need rigorous pre-specified design (in addition to the willingness to fold when your hypothesis is not possible to answer with the data at hand). #EpiSky, #CausalSky, #AcademicSky

Do any other languages (Dutch, German, Spanish) share this quirk, or is English alone in having a verb whose past tense is an exact anagram of its base form?
Are there any other English verbs whose past tense is formed by simply rearranging the same letters (with no additions or deletions) as their present tense — like eat → ate? I can’t think of another example #NLP #linguistics

Thanks for sharing @florianederer.bsky.social Now that’s art — a true masterpiece!
We usually rely on GDP, trade, or wages to study the past. This amazing paper flips the script.
It analyzes 630,000 paintings (1400-2000) to extract emotions and shows how art tracks living standards, wars, inequality, and even climate shocks.
(How is this economics? Everything is economics!)

This is a cool paper that suggests that AI agents can indeed be used for social science experiments, but that just using a chatbot isn't good enough, instead prompts developed based on social & game theory makes AI agent actions predictive of real human outcomes. benjaminmanning.io/files/optimi...

Peter Temin, economic historian at MIT, has passed away. He worked both on problems of understanding the past (e.g. "Did Monetary Forces Cause the Great Depression?") and how how the past shapes the present (e.g. "The Vanishing Middle Class.") Terrific scholar and mentor, generous critic.

Excessive screentime in early age associated with delayed cognitive development, both directly and indirectly through what it crowds out: play, talk, & exploration. But limited use seems fine.
As conversations in government about regulating screen time for children increase, it's essential to be aware of the best evidence on its consequences.
