This paper investigates the effects on acquisitions of creditor-director presence on corporate boards. Using a hand-collected dataset for boards of large U.S. corporations, we find that companies with creditor-directors are more likely to engage in acquisitions with attributes that are unfavorable to shareholders and favorable to creditors (more diversifying and fewer cash-financed acquisitions). Consistent with these patterns, acquisition announcements are associated with lower shareholder value, higher creditor value, and lower overall firm value when a creditor is present. These results support the hypothesis that conflicts of interest between shareholders and creditors can result in value-destroying acquisitions. In addition, commercial bankers with no lending relationship are not affected by conflicts of interest. Where appropriate, our estimation strategy takes into account that there may be self selection of bankers onto corporate boards.

We present an equilibrium model of financial institutions to examine the optimal regulation of risk taking. Shareholders provide incentives for management to increase risk to excessive levels. Regulators use caps on asset risk and compensation to achieve the socially optimal risk level. This level trades off costs of risk shifting and costs of bank default. Without regulation, equilibrium risk lies above the optimal level. If information and enforcement are perfect, either policy tool (caps on asset risk or compensation) achieves the optimal risk level. If there are frictions – if enforcement is limited, if there is uncertainty about the incentives facing management and costs of risk shifting, or if regulation cannot be bank specific – welfare can be improved by employing both policy tools.
