Ronald Coase is widely recognised as one of the most influential economists of the 20th century. In this new volume, Matthias Klaes argues that Coase is a self-styled disciplinary renegade, whose aim for the past four decades has been to re-orient the shape and practice of modern economics. This book will provide an account of the alternative economics present in Coase's work, offering a balanced analysis of the full breadth of his writings over eight decades.
