Congrats to UZH.
One can read in terms of Hirschman’s Exit/Voice/Loyalty framework: the pull of sentimentality toward MIT is weak when there is abundant work to be done on global poverty and the broader home
environment is so bleak.

I am delighted to share that Nobel laureates Esther Duflo and Abhijit Banerjee will join our Department of Economics @econ.uzh.ch at the University of Zurich on July 1, 2026, as Lemann Foundation Professors of Economics.

Currently in FirstView: “Generalizing Trimming Bounds for Endogeneously Missing Outcome Data Using Random Forests." @cdsamii.bsky.social, Ye Wang, @jlzhou.bsky.social present a partial identification approach that avoids strong assumptions. This is illustrated using a simulation and replication.

Agreed — nice round up of very well informed perspectives. I found Raleigh’s analysis especially convincing but all perspectives were thought provoking.

This is a lovely post comparing algorithms to compute OLS coefficients
After two weeks, I'm finally done!
In this post, I explain different approaches for solving linear regression in R: directly, using QR, singular value and Cholesky decompositions, and do some benchmarking for comparison with in-built approaches.

New paper! Regression is motivated in binary treatment settings as producing a convex, conditional-variance-weighted average of heterogeneous treatment effects, but in the continuous treatment case estimates the slope of the true DRF at a point that may not exist in the data. Do AIPW when feasible

Does Residuals-on-Residuals Regression Produce Representative Estimates of Causal Effects? (Lal, Chou) Double Machine Learning is commonly used to estimate causal effects in large observational datasets. The "residuals-on-residuals" regression estimator (RORR) is especially popular for it
