Offering a historical analysis of management in banking from the Medici to present day, this book explores how banks can cause devastating financial crisis when they fail. Rather than labelling management as ‘good’ or ‘bad’, the author focuses on the concept of absent management, which can occur as a result of complexity. The complexity of banking, which intensified alongside the phenomenal growth of banks in the 20^th and 21^st centuries, resulted in banks that are mismanaged or, at times, even unmanaged. Drawing on business school case studies including Barings and Lehman Brothers, this book showcases how absent management in banking has caused crises, depressions and recessions, and how ultimately it will continue to do so.
