| QUALITY OF BOARD OF DIRECTORS, OWNERSHIP STRUCTURE AND LEVEL OF VOLUNTARY DISCLOSURE OF LISTED COMPANIES IN THAILAND Jakkravudhi Chobpichien, Hasnah Haron & Daing Nasir Ibrahim Issue 33 (Vol. 17, No. 1), June 2007, pp. 3-39. The study investigates whether board of directors (BOD) and ownership structure influence the voluntary disclosure index (VDI) of public listed companies in the Stock Exchange of Thailand. The findings suggest that VDI is influenced by the quality of BOD and the ownership structure of the firm. The higher the quality of BOD, the higher is the VDI. This relationship is moderated by the largest shareholder controlling ownership. In addition, this relationship appears to be weaker for companies with a high concentration compared to a low concentration of CEO controlling ownership. Finally, firm characteristics as control variables comprising size of company, auditor type, and earnings return are found to have a significant influence on VDI. |
