Demonstrates how fund-family advisors use subsidization to influence fund performance and market efficiency.
This paper studies how fund-family advisors use cross-fund subsidization to manipulate fund performances and maximize fund-family values, and how this activity shapes market equilibrium. The trade-off between subsidization efficiency and funds’ endogenous profit-performance convexities determines the subsidization. When the effect of profit-performance convexities dominates, advisors optimally use low-value funds to subsidize high-value funds. When the effect of subsidization efficiency dominates, advisors use liquid funds to subsidize temporarily distressed funds. The subsidization induces negative asymmetric cross-fund flow-performance sensitivities: high-value (liquid) funds’ performances strongly decrease low-value (temporarily distressed) funds’ flows, whereas low-value (temporarily distressed) funds’ performances weakly reduce high-value (liquid) funds’ flows.
