Out of Sight, Out of Mind: The Effects of Expenses on Mutual Fund Flows

Abstract

We argue that the purchase decisions of mutual fund investors are influenced by salient, attention-grabbing information. Investors are more sensitive to salient in-your-face fees, like front-end loads and commissions, than operating expenses; they are likely to buy funds that attract their attention through exceptional performance, marketing, or advertising. Our empirical analysis of mutual fund flows over the last 30 years yields strong support for our contention. We find consistently negative relations between fund flows and front-end load fees. We also document a negative relation between fund flows and commissions charged by brokerage firms. In contrast, we find no relation (or a perverse positive relation) between operating expenses and fund flows. Additional analyses indicate that mutual fund marketing and advertising, the costs of which are often embedded in a fund's operating expenses, account for this surprising result.
