Do search costs explain persistent investment in active mutual funds?

Abstract

Active funds, though losing market share since the 1990s, make up nearly half of all mutual funds but charge more without better performance. We analyze fund data and a search model, highlighting the impact of search costs and active fund preferences. From 1993 to 2018, reduced search costs expanded the market and heightened competition, while a preference shift from active to passive funds increased the latter's market share. However, investors who choose active funds, facing higher search costs, and continue to show a strong preference for them, allow these funds to keep charging higher fees.
