Hong, Bryan, Frank Li, and Dylan Minor. “Corporate Governance and Executive Compensation for Corporate Social Responsibility.” Working paper (Harvard Business School), 2015.
From the authors' abstract: "We test our predictions [from an agency cost model] using novel executive compensation contract data, and find that firms with more shareholder-friendly corporate governance are more likely to provide compensation to executives linked to firm social performance outcomes. Also, providing executives with incentives for CSR is associated with a higher level of engagement in CSR activities at the firm level. The findings provide evidence identifying corporate governance as a determinant of managerial incentives for social performance, and suggest that CSR activities are more likely to be beneficial to shareholders, as opposed to an agency cost."
