Where grocery stores are located is not random. In this R.E.A.L. post, we map grocery store locations across California and link them to neighborhood demographics. Premium grocers cluster in high-income, highly educated renter areas, while store closures disproportionately affect lower-income communities. A small data look at how retail geography reflects urban inequality. realab.blog/p/the-geograph…

Doesn't work if you have a bike rack, though

explain to me why we are never going to get universal income despite super productivity

Not sure why people say that using AI for writing is slop, please explain

I am definitely doing tenure wrong. Someone should have told me what to do before giving it to me.

Would gladly go back to pre-AI world.

Scombubolating....

AI will not reduce burnout in academia; it will compress it. If writing, coding, and first drafts take a fraction of the time, the equilibrium just shifts, the bar moves, expectations adjust, and deadlines tighten. Output increases, review cycles accelerate, and “quick revisions” multiply. The constraint was never typing speed; it was attention and judgment. AI relaxes the production constraint, not the evaluation constraint, so burnout simply arrives sooner.

New on R.E.A.L. 🏠 How has residential mobility changed over the past decade? In our latest post, we use U.S. Census SIPP data to track transitions between owning and renting across three panels (2013–2023). Key takeaways: 📉 Owner-to-owner moves dropped sharply in 2021–2023, consistent with the mortgage rate lock-in effect — millions of homeowners locked in at historic lows now face steep penalties for moving. 📉 Renter-to-renter mobility declined ~40% in under a decade. 🔍 A surprising finding: own-to-rent transitions are more frequent than expected, but a deeper look reveals they're largely driven by young adults leaving family homes — not homeowners selling to become renters. The distinction between individual-level and household-level data matters enormously for interpreting these trends.

As States Permitted Online Sports Gambling, Citizens’ Personal Financial Health Suffered - UCLA Anderson Review anderson-review.ucla.edu/as-states-perm…

Reminder: if you’re a brilliant jerk, people won’t want to work with you. True in both academia and industry.

We just posted the full paper about this: papers.ssrn.com/sol3/papers.cf…. Comments are welcome!

One of the authors here. It is not true that papers are publishable simply because they conclude that gambling is harmful. Nor is it our intention to present a biased analysis (there is no incentive for us to do so). In response to your concern about the different results for credit card delinquencies, note that we have revised the definition of online treatment in the new draft. In the current draft, it is labeled Retail-to-Online and defined over a set of states that already permit retail gambling (which is very different than the previous definition). This design allows us to identify the incremental effect of introducing online gambling in states already having retail access.

We often hear that a negative effect of legalized sports gambling is a rise in consumer bankruptcies. A concern I had is, given that the identification comes from staggered rollouts of state legalizations, with effectively a handful of observations, how robust is that result? And how large?

I am not opposed to editors publishing in their own journals, but look at the Management Science publication count for David Simchi-Levi, who was EIC from 2019 to 2023.
