This book explores the causes of rising income inequality within industrialised, developing, and emerging economies. The development of finance capitalism over the last 40 years is charted to highlight how the neoliberal restructuring of national and global economies has driven income inequality. With case studies from the USA, South Korea, Argentina, and Sweden, a comparative analysis is presented to reveal how financialisation facilitates uneven capital accumulation and generates conditions that increase income inequality. This book aims to outline an analytical framework for a financialisation-induced income inequality nexus. It will be relevant to students and researchers interested in the political economy and financial economics.
