Strict Universality of the Square-Root Law in Price Impact across Stocks: A Complete Survey of the Tokyo Stock Exchange

Episode 21

Using complete account-level trading data across all liquid TSE stocks over eight years, the authors find the market-impact exponent is statistically consistent with 1/2 at both stock and trader levels—strong evidence for strict universality of the square-root law.

Building compositional tasks with shared neural subspaces

Episode 21

The study shows that monkeys flexibly switch tasks by reusing shared, low-dimensional "neural subspaces" for sensory features and actions, composing them differently depending on the current task.
