We examine the impact of geographic concentration of institutional investors on corporate governance and firm value. We find that firms whose large institutions are closely located to each other experience more shareholder-coordinated activities before Schedule 13D filings, more concerted proxy votes against management proposals, higher forced CEO turnover-performance sensitivity, higher returns around CEO turnover announcements and Schedule 13D filings, and larger increases in Tobin's q. These results are robust to using the introduction of new direct airline routes as an exogenous source of variation in proximity. Our results suggest that geographic concentration of investors increases monitoring effectiveness.

We examine the relationship between shareholder leverage constraints and corporate risk-taking, focusing on its impact on debtholders. Our findings show that mutual fund leverage constraints are related to more risk-taking activities of portfolio companies, inducing higher credit risk and greater risk-shifting concerns for the firms’ debtholders. In response, the debtholders raise borrowing costs and tighten lending conditions. These effects intensify for firms facing higher levels of conflict between debtholders and shareholders and when mutual funds exert greater influence over firms. Econometric analyses, including instrumental variable specifications and asset management company mergers, support a causal interpretation.
