An integrated framework of corporate Governance and firm valuation

Abstract

Recent empirical research shows evidence of a positive relationship between the quality of firm-specific corporate governance and firm valuation. Instead of looking at one single corporate governance mechanism in isolation, we construct a broad corporate governance index and apply five additional variables related to ownership structure, board characteristics, and leverage to provide a comprehensive description of firm-level corporate governance for a representative sample of Swiss firms. To control for potential endogeneity of these six governance mechanisms, we develop a system of simultaneous equations and apply three-stage least squares (3SLS). Our results support the widespread hypothesis of a positive relationship between corporate governance and firm valuation. © Blackwell Publishers Ltd, 2006.
