This book focuses on the extensive literature on corporate governance that attempts to answer the question: what is the value of corporate governance to US firms? Also discussed herein is how corporate governance in business, finance, economics, management, and accounting is widespread and continues due to the struggles (and in some cases, collapse) of major firms world-wide. Following the global financial crisis in 2007-2008, even though most of these firms have strong governance structures. Moreover, most of these broad studies lack evidence of the systematic usefulness of corporate governance to different constituencies, especially to firm value, performance, and financial reporting quality.
