Herein below you can read/ access my latest posts from the BlueSky and Twitter (X) platforms (the custom Twitter (X) feed updates with a substantial lag and sometimes chaotically). You are obviously better off reading/ following me directly on Twitter (X) and/or on BlueSky and/or on Mastodon and/or on Threads for full functionality. (NB. The latter three platform feeds, unlike Twitter (X), are readable also if not logged in on the corresponding platform.)
Melissa Aldana & Gonzalo Rubalcaba’s new Tiny Desk is spellbinding (with superb support from Pablo Menares on bass & Kush Abadey on drums). No lyrics, nothing left unsaid!
P.S. Lucky to have heard Aldana live exactly a decade ago at Fasching, in Stockholm!
Congratulations to David Kazhdan and Joseph Bernstein for receiving the 2026 Wolf Prize in Mathematics “for foundational work on representation theory, automorphic forms and algebraic geometry, and their role in creating geometric representation theory.”
An interesting perspective (as one would expect) from Kevin Buzzard.
To grieve, or not to grieve?
Recent events in the field of AI for mathematics have shown us beyond all reasonable doubt that the field is c...

Looking forward to presenting research on “Valuing Jobs with Unobserved Offers” tomorrow in the Applied Microeconomics seminar at the PUC. Come for the sharp bounds... or because your outside options are worse. My identification problem starts at the door.

Santiago no es Chile
Y necesitamos datos geográficos para un desarrollo descentralizado
Ayer lanzamos las cuentas económicas desagregadas para Chile
Mostramos que es imposible pensar (y fomentar) la actividad económica sin considerar los territorios donde ocurre

How should long-term employment contracts be regulated? We show that optimal regulation prices the use of non-competes, tying stronger non-competes to higher wages. This limits inefficient worker lock-in and raises pay at better matches.

Lui Patrick de Hillerin i-am apreciat argumentele chiar când nu am fost de acord cu el. L-am admirat: un jurnalist cum RO abia mai are. Prostia și răul au un adversar în minus, dar nu și ultimul cuvânt: ne-a învățat să nu tăcem.
Merci, Patrick. Repose en paix. Nous, on continue.
Our garden 𝑎𝑠𝑎𝑑𝑜 field experiment this past Saturday successfully converted prime cuts and top-shelf liquid assets into social capital. With company this brilliant and merry, diminishing returns never materialized.
Some missed the group shot, but everyone lit up the evening!
"Machine Learning for Dynamic Incentive Problems": @comp_simon & @PhilippJRenner introduce a framework combining penalties, Gaussian processes and Bayesian active learning to bypass set-valued dynamic programming. Handles at least 10 persistent types."
