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.

超越二分法中的布莱克韦尔顺序

我为二分法建立了布莱克威尔秩的翻译不变性属性，并证明与同一矩阵的距离的规范可解释为信息量的度量。更好的实验更接近于完全揭示性实验；这一度量扩展了布莱克威尔秩，是完整的，并且与先验无关。

期刊介绍： Many economists today are concerned by the proliferation of journals and the concomitant labyrinth of research to be conquered in order to reach the specific information they require. To combat this tendency, Economics Letters has been conceived and designed outside the realm of the traditional economics journal. As a Letters Journal, it consists of concise communications (letters) that provide a means of rapid and efficient dissemination of new results, models and methods in all fields of economic research.
