Mixtures of Mean-Preserving Contractions
Joseph WhitmeyerMark Whitmeyer
文献摘要
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.
