Do Mutual Fund Companies Eat Their Own Cooking?

Abstract

The authors find that mutual fund companies offer mostly their own mutual funds in the 401(k) plans for their own employees. However, there are systematic differences between companies that rely on their own funds and companies that include outside funds. The companies that include outside funds tend to operate funds with high expense ratios. Outside funds in the 401(k) plans of mutual fund companies have significantly lower expense ratios and better governance scores than company’s own funds. This evidence supports the claim that the interests of mutual fund companies are not perfectly aligned with the interests of their funds’ shareholders. The authors also find that among the company’s own funds, the funds selected for the company’s 401(k) plan are almost indistinguishable from the rest of the funds offered by the mutual fund companies. Thus, it is not the case that, within their own funds, mutual fund companies favor their inexpensive funds. In fact, within the companies’ own funds, participants (mutual fund company employees) gravitate towards higher-cost and more actively managed funds. Thus, in one context (choosing to use outside funds) mutual fund companies favor cheap and better governed funds, in another context (choosing among its own funds) mutual fund companies favor actively managed, expensive funds.
