📢New paper in PNAS! How rich was Vienna at the time of Mozart or Tuscany at the time of Michelangelo? Historical GDPs per capita are scarce, leaving this unanswered. Here, we provide new estimates using machine learning to augment historical GDPs per capita. /1 🧵

What do fame, historical GDP, and gender equality in science have in common? They were all explored by our colleagues at @IC2S2 2025! 👏Congratulations to @philippmkoch for winning the Best Parallel Talk award this year, and huge thanks to @zappala_chiara & @mel2kill for their…

NEW PAPER: The Theory of Economic Complexity The Economic Complexity Index or ECI is a widely used empirical tool with an unclear theoretical basis. In this paper, we change that by formally deriving ECI for several production functions and showing what it really does. In a…
