That’s exactly what we find in our paper! Firms that adopt GenAI reduce the number of junior employees, and this effect operates entirely through a decline in hiring rather than increased separations. Link to draft: papers.ssrn.com/sol3/papers.cf…

The Criminal Justice team at Arnold Ventures is looking for a pending/recent PhD with strong causal inference skills, for a remote, part-time consulting position. This is a great opportunity for someone considering a transition from academia to the policy space. You'll learn a lot and meet lots of people! Deadline to apply: March 15 Please RT!

Call for papers: PhD students and junior scholars working in the economics of crime space - check out this excellent conference in London.

Excited to team up w/ @SdsuEcon for a fabulous Spring’26 Seminar Series ft. C. Sloan, @kteltser, @Viquibarone, @MatthewGudgeon, @serenacanaan, @claudferraz, @kylefbutts, M. Fitzpatrick, @james_m_reeves, @econ_mar, @TaniaMocanu, @tpearson_tweets, @amguoo, @ParagMa_Econ & P. Oliva

I just posted the ViCE seminar schedule for early spring 2026:

Cool job alert: "Postdoctoral Scholar: Criminal Justice Research Center & PA Department of Corrections" This is an opportunity to contribute to the fantastic research program at @CorrectionsPA under @kbucklen. They're doing some of the most innovative, rigorous work in the public safety space. And they're looking for someone with causal inference skills to help them do even more.

We should probably be placing incarcerated people in prisons closest to their homes. Why? Assigning individuals to prisons closer to their home reduces recidivism. Really? Yep. Being placed close to one's home increases social contacts that appear to reduce reoffending.

Dave Hall presenting research with @q_econ on the impacts of drug legalization in Oregon. Prior research has found different estimates using the same methods. We replicate, reconcile and extend prior research. @APPAM_DC #appam2025

New working paper with @JeffDenning, @benconomics, @LarsLefgren & Cody Tuttle: 📄 “Same Crime, Different Time: Disparities in Judicial Outcomes for DWI Offenders.” We study how similar DWI defendants can face very different sentences. 1/5

Since it's the job market season, if you want a signal boost for your JMP post, let me know via DMs and I'd be happy to retweet/quote-tweet.

This morning, the @chicagofed introduced new labor market indicators that combine private sector data with official labor statistics to provide a real-time view of hiring, layoffs and other job separations, and an early forecast of the unemployment rate. chicagofed.org/research/data/….

@benconomics 🥺🥺

Sometimes it's hard to say goodbye to former students. @q_econ headed off to make the world a better place.

Y’all, I wrote a book! The Science of Second Chances is based on my decades of work studying crime and criminal behavior, first as an economics professor and now as a policy expert at Arnold Ventures. It shares what we know from cutting-edge research about how to intervene at each stage of the criminal justice process to break the incarceration cycle and give people a real second chance. Most books in the criminal justice space have a “burn it all down” vibe — pointing out lots of problems and leaving readers feeling hopeless. But I work in this field and feel hopeful and optimistic every day. There are so many effective ways to put people on a better path, and we’re learning more about what works all the time. This book is a product of that optimism, focusing on solutions. I share many feasible interventions that make a big difference — alongside cautionary tales of good ideas that did not pan out, or even backfired. And I also share how economists like myself learn what works, through careful trial and error, in order to make big, scalable change a reality. I hope these ideas spur fresh conversations about how to help people and communities thrive. The Science of Second Chances is available for pre-order now, and will land on your doorsteps or e-readers on February 24. Please share with your networks. 🙏🏻
