Blackwell's informativeness theorem using diagrams

Henrique de Oliveira

Games and Economic Behavior, 2018, vol. 109, issue C, 126-131

Abstract: This paper gives a simple proof of Blackwell's theorem on the ranking of information structures. The proof extends naturally to environments where information arrives over time (leading to the notion of adapted garbling) and environments where information is diffused among multiple players (leading to the notion of independent garbling).
