Prior studies have found that a firm advertising for one of its products not only can increase the sales of the advertised product, but also spill over the advertising effect by increasing sales of other existing products in the same brand. This study examines whether a fund family spending money on one of its managed funds can attract more money flows into the advertised fund and bring the advertising spillover effect that attract more money flows into other members in the same family. Under the assumption that a fund family is a risk aversion investor endowed with a negative exponential utility function, this study finds a theoretical allocation proportion for a fund family¡¦s spending on advertising of individual funds under management, which is the function of the fund family¡¦s risk aversion level and initial wealth, as well as the mean and the variance of the expected returns generated by individual funds¡¦ advertising and the advertising spillover effect. Empirically, the evidence shows that an advertised fund can significantly attract greater cash flows and bring the significant advertising spillover effect on cash flows of other individual funds in the same family. After grouping funds into lower-, mid- and higher-performing funds based on funds¡¦ past performance, the results indicate that an advertised fund with mid performance can attract greater cash flows than an advertised fund with higher and lower performance. Moreover, an advertised fund can bring stronger advertising spillover effect on cash flows of higher-performing funds than lower- and mid-performing funds in the same family. Regarding with the family cash flows, the evidence shows that a fund family¡¦s aggregating advertising expenditures on managed funds can significantly increase the family cash flows and the advertising effect on the family cash flows is stronger in large families than in small families. The empirical results suggest that a fund family can benefit from its advertising expenditures and which allocating higher proportion for advertising of mid-performing funds than higher-performing funds could attract money flows into its managed funds more efficiently.
