August 2007Differences in Governance Practices between U.S. and Foreign Firms: Measurement, Causes, and Consequences
with Reena Aggarwal, René Stulz, Rohan Williamson: w13288
Using an index which increases as a firm adopts more governance attributes, we find that 12.7% of foreign firms have a higher index than matching U.S. firms. The best predictor for whether a foreign firm adopts more governance attributes than a comparable U.S. firm is whether the firm comes from a common law country. We show that the value of foreign firms is negatively related to the difference between their governance index and the index of matching U.S. firms. This relation is robust to various approaches to control for the endogeneity of corporate governance and is consistent with the hypothesis that foreign firms are valued less because country characteristics make it suboptimal for them to invest as much in governance as comparable U.S. firms. Overall, our evidence suggests that firm...
January 2007Do U.S. Firms Have the Best Corporate Governance? A Cross-Country Examination of the Relation between Corporate Governance and Shareholder Wealth
with Reena Aggarwal, Rene M. Stulz, Rohan Williamson: w12819
We compare the governance of foreign firms to the governance of similar U.S. firms. Using an index of firm governance attributes, we find that, on average, foreign firms have worse governance than matching U.S. firms. Roughly 8% of foreign firms have better governance than comparable U.S. firms. The majority of these firms are either in the U.K. or in Canada. When we define a firm's governance gap as the difference between the quality of its governance and the governance of a comparable U.S. firm, we find that the value of foreign firms increases with the governance gap. This result suggests that firms are rewarded by the markets for having better governance than their U.S. peers. It is therefore not the case that foreign firms are better off simply mimicking the governance of comparable U...
