Directors are key decision-makers in any organisation, whether it is in the public sector, a family business or a transnational company. The UK Companies Act 2006 codified directors' duties for the first time and describes the director as the 'most likely to promote the success of the company for the benefit of its members as a whole'. This book addresses key tensions and problems involved in the duties and responsibilities of the director in promoting success, including corporate culture and credibility, trust, risk and uncertainty, collective responsibility, and the degree of control. The book considers directors' decision-making in both private and public sector organisations and explicitly examines aspects of decision-making during periods of financial distress. The book compares the legal contexts of director's decisions in the UK to those of the USA, Germany and Australia, and takes an interdisciplinary approach in its combination of management theory, economic theory and behavioural studies. In doing so the book addresses issues key to the understanding of corporate governance in light of recent financial crises.
