Abstract
We develop tests for mean-variance efficiency of international equity markets for ten OP countries. A Wald test that allows for time-varying variances of excess returns rejects a version of MVE. The source of t he rejection is not entirely clear, so we use a minimum distance estim ator to estimate the mean-variance efficiency model. While we formally reject the MVE constraints in this model, the estimated constrained a sset demand equations are revealing.
