Informational separability and entropy

Journal of Economic Theory, 2024, vol. 216, issue C

Abstract: Informational separability occurs when information decreases as the result of suppressing information that differentiates a subset of states in experiments. With multiple states, informational separability leads to entropy measures. Its implications in multiple different contexts are discussed, including segregation measurement, inference with partial information, and rational inattention.
