The Interrelationship Between Managerial Ownership and Board Structure

The paper tests the hypothesis that high managerial ownership entrenches managers by allowing the CEO to create a board that is unlikely to monitor. The results show a strong negative relationship between the level of managerial ownership and corporate governance factors, such as, the split of the roles of the CEO and the Chairman, the proportion of non-executive directors, and the appointment of a non-executive director as a Chairman. I also find that companies with low managerial ownership are more likely to change their board structure to comply with the Cadbury (1992) recommendations. The results suggest that managers, through their high ownership, choose a board that is unlikely to monitor. Overall, the findings cast doubt on the effectiveness of the board as an internal corporate governance mechanism when managerial ownership is high.

Corporate governance mechanisms and financial performance in China: panel data evidence on listed non financial companies

The objective of this paper is to provide empirical evidence on the influence of corporate governance characteristics and corporate ownership concentrations on the financial performance of Chinese companies. This is based on analysis of a panel data set covering the years 2001 to 2005. The characteristics considered are the ratios of independent directors and professional supervisors on the companies' two boards, and the level of concentration in and type of ownership of the companies. Our chosen performance metric is Tobin's Q. We find that ownership concentration in general is a significant factor in determining firm performance. The degree of board independence is significant, but it only appears to have a positive impact on performance in larger companies. The expertise of the supervisory board is not a significant determinant of corporate financial performance in China. Our findings support a continued focus on making improvements to the operation and effectiveness of China's institutions of corporate governance.Yuan George Shan and Ron P. McIve
