Corporate Governance and Shareholder Value in Listed Firms: An Empirical Analysis in Five Countries (France, Italy, Japan, UK, USA)

In this paper, we design a multi-dimensional index to measure the quality of Corporate Governance systems adopted by firms and use it to investigate the correlation between Corporate Governance quality and firm value. Unlike most studies that examine the relationship between only one dimension of Governance and firm value, we present a complex index (CGI) composed of 39 variables referable to four dimensions: Board, Remuneration, Shareholder Rights and Disclosure. By analysing a sample of 100 large companies listed on the main stock markets in five different countries over three years (2009-2011), we confirm the widespread hypothesis of the existence of a positive and statistically significant relationship between Corporate Governance, as measured by a subset of 12 variables, and firm value
