        I’ve never heard the term before, but it’s so fitting! If there’s room, I found a suspicious discontinuity in NYC restaurant hygiene ratings (suspicious cliff just before the cutoff between “A” and “B” grades) 🤥

        An excellent seminar is a great way to end a tough week on a high note. @natazino presented her fascinating paper showing that the discontinuity in earnings at 0.5 within couples is driven by co-working spouses.

        I have always been fascinated by age heaping in census data, which I guess is a different kind of discontinuity https://familyinequality.wordpress.com/2015/07/13/their-answers-will-shock-you/ …pic.twitter.com/QLVtPYIq2h

        People playing speed chess (presumably) get fixated on improving their Elo rating by the next 100 point span, leading to spikes every 100 rating points in the distribution: https://lichess.org/stat/rating/distribution/bullet …

        I don't understand the ACA subsidy point. Don't the ACA subsidies phase out? (You get more of a subsidy at AGI of $10k than at $40k) Why is the last quantum so important?

        I enjoyed reading this, though I did notice a persistent typo: It's UEFA, not UFEA
