Hey I keep saying this and now Allison Schrager has written an article about it for Bloomberg. Tenure is a form of compensation. If you think tenure is a bad way to pay teachers, and that compensation is best in the form of dollars, that’s fine; but if California pretends that the elimination of tenure isn’t a massive pay cut for teachers, they’re making a basic economic mistake.
New “hot hand” paper by Brett Green and Jeffrey Zweibel, about the hot hand for batters in baseball. They say it’s there! And they echo a point I make in the book (which I learned from Bob Wardrop) — some of the “no such thing as the hot hand” studies are way too low-power to detect a hot hand of any realistic size.
