Abstract

In this paper we relate the board's attributes to the firm's opacity as measured by the adverse selection component of the bid-ask spread. We find that larger boards and outside directors are associated with reduced opacity, especially in freestanding firms. However, directors' excess control is associated with a significant increase in firm's opacity. We also find that the presence of family pyramidal holding defuses any potential monitoring benefits of board attributes. Our findings suggest that the firm's ultimate ownership structure is not neutral in determining the monitoring effectiveness of the board of directors. This might help explain existing mixed evidence on the monitoring role of the board of directors.
