Investing in Low-Trust Countries: On the Role of Social Trust in the Global Mutual Fund Industry
研究发现社会信任能缓解合同不完备性，促进全球共同基金的主动管理并提升业绩，跨境投资中信任带来的主动份额每年带来约2%的超额收益。
Abstract We hypothesize that social trust, in mitigating contracting incompleteness, may have an important effect on the activeness and effectiveness of delegated portfolio management. Using a complete sample of worldwide open-end mutual funds, we find that trust is positively associated with the activeness of funds and that trust-related active share delivers superior performance (e.g., approximately 2% per year for cross-border investments). Moreover, “trust in the market” and “trust in managers” play important yet different roles for different types of cross-border delegated portfolio management. Our results suggest that trust acts as a fundamental building block for delegated portfolio management.
