Forthcoming in the AER: "Supply, Demand, Institutions, and Firms: A Theory of Labor Market Sorting and the Wage Distribution" by Daniel Haanwinckel. aeaweb.org/articles?id=10…
Why are wages in Paris or NYC higher than in other cities? In a new WP with @PaulineCarry & @BennyKleinman , we decompose spatial disparities btw “location effects” and the local composition of workers and establishments. New data on firm mobility + double-mover design. 🧵⬇️

Our study shows that people behave more morally in uncertain situations than in certain ones. This may be because they simply feel less anxious by acting morally when faced with uncertainty, or believe in karma where moral actions lead to better outcomes. econometricsociety.org/publications/e…

A somewhat common (though unsurprising) reaction I have seen to this paper is "oh caste is important for India, not for US." This is partly due to US-centrism in econ academia, and is also intellectually limited. Unlike Western settings, where socioeconomic status often must be…

New research paper alert! 🚨 I've combined economics with ideas from biochemists and medical doctors to explore what's driving obesity and other metabolic diseases. The main finding? Vegetable seed oils seem to play a big role. 🌱🛢️ (1/25) tyleransom.github.io/research/obesi…

External validity: seeing this more and more in my journal editing. Note that every result is valid to some setting, no result is externally valid to all settings. Let's think about how preferences, beliefs, or constraints differ across the experimental and target setting(s)…
Individual managers impact retail business productivity substantially. Replacing a low-quality manager w/ a high-quality manager could increase a store’s productivity by between 50%-100%. @ChicagoBooth's @ChadSyverson, @RDMetcalfe, @ASollaci ow.ly/3Ls450QYQRg
Related to @littmath's excellent problem a while back: Suppose Bob and Alice play a new game where they flip a fair coin N times. Alice wins if more than 24% of the coin tosses are 3-streaks (HHH or TTT). As N gets large, how much of the time does Alice win?
Interesting new @nberpubs paper out by @giov_peri and Caiumi. They find evidence of strong immigrant-US-born complementarity among college-educated workers in the post-2000 period. nber.org/papers/w32389
Seeing what’s happening with post-docs on the econ job market & pre-docs among grad school applicants truly leaves me sad for our profession. We are screening out people who can’t/won’t spend 10 years preparing for a job as a PhD economist!
Most workers in developing countries are self-employed. Would there be transformational gains from organizing them into firms? In this (possibly controversial) paper 👇 we argue “maybe not”. Why? Because there is very small labor specialization even in larger (Ugandan) firms.
