The course provides a broad coverage of heterodox economic models. The course starts with a review of the Ricardian origins of heterodox models. The Keynesian contribution, its dynamic extension, the Harrod-Domar model, and further developments based on it are discussed. The Sraffian theory and the critique of marginalist distribution theory is provided within the framework of a linear model of production and distribution. Kaleckian models that have become prominent over the last few decades are introduced. The Post-Keynesian endogenous money and the contributions of Hyman Minsky are also discussed.
