Variance Covariance Orders and Median PreservingSpreads

A random variable dominates another random variable with respectto the covariance order if the covariance of any two monotone increasingfunctions of this variable is smaller. We characterize completely thecovariance order, give strong sufficient conditions for it, present a numberof examples in concrete economic applications, and provide naturalextensions for the multivariate context.[...]
