Text-to-data In wfhmap.com we found defining WFH job postings using keywords is tricky. Many started including terms like "work remotely" from April 2020, but followed by "no" or "not possible". So we human read 5k articles used it to train a BERT NLP called WHAM.

I thought I might ruin your day as well by making you feel old. Today I showed my undergraduate students one of these. None of them had any idea what they were looking at. Do you? Hint: you needed a handful of these to install Doom.

Thrilled to have a new working paper on AI and Cross-border Data Regulation with Dan Trefler! We use a LLM approach to link each product (app) to each technology (patent), to quantify the direct and spillover effects on AI deployment in an international dimension

RIP Jonathan Eaton, a great economist that transformed the field of international trade. He should have received a Nobel prize for his many invaluable contributions to economics.
