We evaluate why individuals invest in high-fee index funds. In our experiments, subjects each allocate $10,000 across four S&P 500 index funds and are rewarded for their portfolio's subsequent return. Subjects overwhelmingly fail to minimize fees. We reject the hypothesis that subjects buy high-fee index funds because of bundled nonportfolio services. Search costs for fees matter, but even when we eliminate these costs, fees are not minimized. Instead, subjects place high weight on annualized returns since inception. Fees paid decrease with financial literacy. Interestingly, subjects who choose high-fee funds sense they are making a mistake. The Author 2009. Published by Oxford University Press on behalf of The Society for Financial Studies.
