This accessible book provides a non-technical yet rigorous introduction to the various competing schools of thought in economics including, Neoclassical, Marxist, Austrian, Post Keynesian, Institutionalist, New Institutionalist, and Feminist. The unique features of each approach are highlighted, complemented by discussions of methodology, world views, popular themes, and current activities. Importantly, the book also examines common criticisms and how each school responds. In the interest of preserving balance and accuracy, every chapter covering a heterodox school of thought has been vetted by an acknowledged expert in that particular field. Though written for use in undergraduate courses, this guide will no doubt offer a great deal to any scholar wishing to gain a fresh perspective and greater understanding of the variety and breadth of current economic thinking.
