Over the last 15years, dramatically decreasing foreign investment costs have not reduced the home bias. We show that the home bias induced by a given cost is proportional to the factor ρ/(1−ρ), where ρ is the average correlation between markets. This factor is very sensitive to the...

The geometric-mean argument and the recently developed Almost Stochastic Dominance criterion have been employed to make the case for "stocks for the long run". We show that Almost Stochastic Dominance and the geometric-mean argument do not necessarily support long-run investment in equities. In...

Recent models of the evolution of preferences have provided profound new insights into the origins of risk attitudes. In most of these models the evolutionary “objective function” is the maximization of the expected number of offspring, or alternatively, the maximization of the...

Cornerstone asset pricing models, such as capital asset pricing model (CAPM) and arbitrage pricing theory (APT), yield theoretical predictions about the relationship between expected returns and exposure to systematic risk, as measured by beta(s). Numerous studies have investigated the empirical...

Numerous studies have examined the mean/variance efficiency of various market proxies by employing sample parameters and have concluded that these proxies are inefficient. These findings cast doubt about the capital asset pricing model (CAPM), one of the cornerstones of modern finance. This...
