Given a purely atomic probability measure with support on n points, P, any mean-preserving contraction (mpc) of P, Q, with support on m > n points is a mixture of mpcs of P, each with support on most n points. We illustrate an application of this result in economics.

均值保留收缩的混合物

给定一个支持 n 个点 P 的纯原子概率度量,任何支持 m > n 个点的 P、Q 的均值保持收缩 (mpc) 是 P 的 mpcs 的混合,每个都支持最多 n 个点。我们举例说明了这一结果在经济学中的应用。
