However, both the anthropological and economic literature are silent on the potential impact of the risk of polygamy on economic decisions of monogamous wives.

We examine pure no-load funds over a 5-year period. For equity funds, trading activity is negatively related to returns. Expense ratios are not significantly related to returns.

Expense ratios and tax cost ratios are negatively related t...
