Book excerpt: As today’s world develops and evolves, so does its economics. New economic approaches have begun to emerge, but traditional methods are still being implemented. As both systems provide different solutions to society’s economic issues, thoughtful research and analysis is required regarding the tactics and strategies that both theories utilize. Comparative Approaches to Old and New Institutional Economics is an essential reference source that discusses the sequential history of these two economic theories as well as their application to global fiscal disputes. Featuring research on topics such as international relations, business management, and institutionalism, this book is ideally designed for economists, analysts, managers, researchers, practitioners, academicians, and students seeking coverage on the parallel methods of these economic philosophies.
