Yen carry trades have made headline news for over a decade. We examine the profitability of such trades for the period 2001-2009. Yen carry trades generated high mean returns and Sharpe ratios prior to the recent financial crisis. They continued to outperform major stock markets for the full...

The pricing of A-shares in China has long puzzled financial economists. This paper applies recent tests of stochastic dominance (SD) to examine whether differences in the return distributions of A- and B-shares in China are consistent with market efficiency. As SD is nonparametric, market...

A new family of spectral shape tests was proposed recently by Durlauf (1991) for testing the martingale hypothesis. Unlike the widely used variance ratio test, spectral shape tests are consistent against all stationary non-white-noise alternatives from the martingale null. In this paper we...

Intertemporal implications of the mixture-of-distributions hypothesis (MDH) are derived based on the concept of time reversibility in statistical mechanics. The restrictions are tested using simple nonparametric tests that do not impose auxiliary assumptions on the stochastic process for trading...

This study employs a new data set to re-examine the book-to-market effect. In contrast to past studies, a direct measure of expected business conditions is used to test whether the value premium is compatible with a risk-based explanation. The measure of expected business conditions is based on...

We examine the problem of time diversification from the viewpoint of prospect theory investors. We use a block bootstrap approach to generate returns of US stocks and Treasury bills for time horizons ranging from 1 year to 20 years. On average, value functions computed using these bootstrapped...
