This course is designed to introduce students to the history of economic thought. We focus on essential ideas of prominent economists and schools of economic thought relating them to real-world problems and when applicable to present-day problems. The course also brings to light the social and economic conditions associated with the emergence of different schools of economic thought. While exploring the economic thought of renowned economists, connections with philosophy and other disciplines will be spelled out. The dynamics of shifts from the prominence of one school of thought to another will also be explored. In this context, the rise and demise of classical political economy and the subsequent rise of marginalist approach will constitute the main axis of the course content. Major controversies over the definition of the objectives, scope, and methodology of economic theories will be surveyed. Various critical departures from the dominant theory will also be taken up.
