Along with addressing core conceptual issues in defining heterodox economics, we will cover in some detail five heterodox traditions in economics: Marxian Economics, Institutional Economics, Post-Keynesian Economics, Feminist Economics, and Ecologi-cal Economics. In the first class meeting, we discuss the structure and goals of the course, as well as the expectations and requirements from the students. In addition, we will discuss the concept of heterodoxy in economics, along with discussing the concepts and key issues in mainstream and neoclassical economics.
