This book contributes to a broader understanding of money doctoring by examining its historical trajectory and cross-sectional variations. We expand the conceptual boundaries of money doctors to include individuals with specialized knowledge in monetary and financial matters who are responsible for identifying, analyzing, and implementing remedies for monetary and financial challenges. Our research focuses on understudied cases from various historical periods and geographical contexts, as well as unexplored aspects of well-established instances, to illuminate the multifaceted nature of money doctors and their impact on economic systems.
