The era of globalisation brought waves of consolidation in business ownership alongside Leviathon-like state actors. Digital disruption too can leave market power in a relatively small number of hands. In organisational and economic terms, global oligopoly is now a fundamental idea for business and society, which this book explores and analyses. This book focuses on global oligopolies, starting with an analysis of global concentration and profits in all sectors, before moving on to illuminate the geographical spread and global strategic orientation choices and performance outcomes of global oligopoly. Contemporary cooperation modes, such as cross-border M&As and strategic alliances, niche and Emerging Market champion strategies are also analysed in detail to move the reader towards understanding likely future directions for the field. Presenting empirical data on strategies and performance outcomes, the book covers a range of industries to provide practical, research-based guidance for more effective global business strategies and policy perspectives.
