Beyond the Blackwell order in dichotomies

Andrew Kosenko

Economics Letters, 2024, vol. 245, issue C

Abstract: I establish a translation invariance property of the Blackwell order for dichotomies and show that the norm of the distance from the identity matrix may be interpreted as a measure of informativeness. The better experiment is closer to the fully revealing experiment; this measure extends the Blackwell order, is complete, and prior-independent.
