  • 演講摘要 : Blackwell has proved that an experiment is more valuable than another if and only if the former is sufficient for the latter. In this paper we give a simple and intuitive proof of Blackwell’s Theorem. It is simple and intuitive in the sense that it is a direct consequence of the duality between beliefs and non-negative contingent claims.
