Field Paper Abstract | Before | After In this paper we empirically investigate potential causes of imperfect competition in the fund market, as characterized by high price dispersion among comparable funds. We discriminate between three main hypotheses on the demand side: a lack of awareness of price dispersion, search costs, and financial illiteracy. A large-scale field experiment is conducted in the Swedish Premium Pension system. Information letters are sent to pension savers in two index funds, where there exists a cheaper fund with the same index strategy. We show that an information intervention that increases the awareness of a cheaper, dominating fund, and reduces the search costs for finding such an alternative, can significantly improve households’ real investment allocations. Nonetheless, a majority of savers who are sent information about the name of the dominating fund do not switch funds. Thus, the high degree of inertia in pension investments remains even when search frictions for identifying dominating alternatives are eliminated. |
