The sharp increase in both gross and net capital flows over the past two decades has led to a renewed interest in their determinants. Most existing theories of international capital flows are in the context of models with only one asset, which only have implications for net capital flows, not...

This paper estimates a lower bound to the foregone gains of incomplete portfolios, which are in turn a lower bound to the (unobserved) entry costs that could rationalize non-participation to financial markets. My estimates provide a heuristic test for the cost-based explanation of limited...

We examine the issue of possible portfolio diversification benefits into seven Middle-Eastern and North African (MENA) stock markets. We construct international portfolios in dollars and local currencies. We compute the ex-ante weights by plugging five optimization models and two risk measures...

We evaluate how non-normality of asset returns and the temporal evolution of volatility and higher moments affects the conditional allocation of wealth. We show that if one neglects these aspects, as would be the case in a mean variance allocation, a significant cost would arise. The performance...
