The book explains and assesses the nature of enlightened shareholder value principle (ESV) and its contribution to corporate governance. Andrew Keay traces the development of the principle of ESV and examines it in the context of existing principles which have influenced corporate governance. The book analyses the UK legislation that delivers the principle in corporate law and ESV is compared to the constituency statutes that apply in the US in order to determine can whether anything can be learned from the American experience with these statutes. Finally the book considers whether ESV will mean a less short-termist approach by financial institutions and non-financial institutions after the global financial crisis.
