🚀 I'm on the #EconSky Job Market! 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. A JMP 🧵👇 (1/13)

Many of the 'facts' that travel the furthest from economic research are based on a flawed method of scaling cross-sectional estimates to the aggregate. @benmoll.bsky.social and I have written about this 'missing intercept' problem, and what economists can do about it, here ⤵️

Our paper provides a method to estimate demand elasticities and infer quality change in settings beyond the CES preferences. Applying method to US imports, we show official measures of inflation in import prices are upward biased bc they don’t account for quality improvements.

I've been working on a new tool, Refine, to make scholars more productive. If you're interested in being among the very first to try the beta, please read on. Refine leverages the best current AI models to draw your attention to potential errors and clarity issues in research paper drafts. 1/

Revisions to economic statistics are not manipulation. Initial numbers should be very current, so they go to bed before all the data are in. Final numbers should be very accurate. /1

Thrilled to have my research feature at @unu-wider.bsky.social’s amazing WIDERAngle blog! Brazil's Bolsa Familia - the world's largest cash transfer programme - does not discourage work. Instead, it increases women's employment by helping them overcome barriers to enter the labour force 👇
