This is a core course that builds on Introduction to Economics. It provides an outline of diverse and alternative macroeconomic theoretical frameworks that has evolved since the Great Depression. Students learn how different theoretical frameworks attempt to explain key macroeconomic variables like output, employment, interest rate and prices depending. The role of macroeconomic policies are analysed under alternative theoretical frameworks. After the completion of the course, students learn to address at least three ​‘real world’ debates in Indian macroeconomics- the debate on labour market policies, fiscal and monetary policies.
