Using a large sample of block acquisitions, this paper examines the governance role of customers that acquire block ownership in supplier shares. We find that compared to targets acquired by noncustomers, those acquired by customers experience higher abnormal announcement returns, larger increases in post-acquisition long-term operating performance, and higher non-routine turnover of poorly performing CEOs. These results are evident when target managerial agency problems are highly detrimental to the supplier–customer relationship. The results support the view that customers’ nonfinancial claims in targets provide customers strong incentives to monitor target managers above and beyond previously documented monitoring by large shareholders.

Using a sample from 38 economies, we examine the relation between bank regulators’ supervisory power and loan spreads. We find that loans issued by banks in economies with more powerful supervisors have higher spreads. The positive association is more pronounced when firms have lower credit quality, when the relationships between firms and banks are less established, when syndicate loans involve fewer lenders, and when lead banks have a riskier profile. Further analyses reveal that loans issued by banks that operate under more powerful supervisors have smaller size and shorter maturity, and the loans are more likely to have collateral requirements and restrictive covenants. Overall, these results suggest that stronger supervisory power of bank regulators affects loan contracting by mitigating lenders’ excessive risk taking.

We study how political capture affects the corporate governance role of the media. Relying on a unique media market in China that is characterized by the prevalence of both state-controlled and market-oriented media, we manually construct a comprehensive financial news sample containing 80,008 articles during the 2004–2010 period and provide evidence that negative coverage by the market-oriented media significantly increases the chance of forced top executive turnover, whereas similar coverage by the state-controlled media has no such impact. A multi-pronged approach that includes an instrumental variable test, an exogenous event, firm fixed effects, and change-in-change specifications provides positive evidence of the casual link. Further analysis reveals that the disciplinary effect of the market-oriented media is stronger for firms that are less likely to be influenced by political capture, such as non-state-owned firms or firms located in provinces with good institutions.

Boards are crucial to shareholder wealth. Yet little is known about how shareholder oversight affects director incentives. Using exogenous shocks to institutional investor portfolios, we find that institutional investor distraction weakens board oversight. Distracted institutions are less likely to discipline ineffective directors with negative votes. Consequently, independent directors face weaker monitoring incentives and exhibit poor board performance; ineffective independent directors are also more frequently appointed. Moreover, we find that the adverse effects of investor distraction on various corporate governance outcomes are stronger among firms with problematic directors. Our findings suggest that institutional investor monitoring creates important director incentives to monitor.
