1/ Could more empathy improve working conditions? In a study with the Philippine government, we find that a family photo, shared with the employer, can reduce mistreatment of migrant domestic workers. Out now in the JPE Micro.

I’ve been doing a series on Claude code for “quantitative social scientists” on my substack. It’s not much a series I guess as much as I am regularly documenting what I’m learning. It started mid Dec 2025 and will continue.

Now, to come back to your first question, two recent papers using AI that I find fascinating are "State of the art" (Gorin, Heblich, Zylberberg) and "Images" (Voth & Yanagizawa-Drott), but you alredy know these😁
