Abstract: Non-parametric tests based on the concept of time reversibility in statistical mechanics are applied to assess the dynamic implications of the mixture-of-distributions hypothesis (MDH). The tests show that shocks to volume and volatility are dynamically asymmetric, thus rejecting the one-factor MDH. © 2003 Elsevier B.V. All rights reserved.
