Notes, Comments, and Letters to the Editor A Note on Stochastic Independence without Savage-Null Events*

We provide two axiomatic characterizations of a stochastic independence property for conditional probability systems, previously proposed by Hammond. One characterization relies on the theory of lexicographic expected utility due to L. Blume et al. [Econometrica 59 (1991), 61 79]; the other relies on the theory of conditional expected utility maximization due to Myerson [``Game Theory: Analysis of Conflict,'' Harvard Univ. Press, Cambridge, MA, 1991]. Journal of Economic Literature Classification Number: D81. 1996 Academic Press, Inc.
