Decision making in business and finance often requires thorough understanding of the modern macroeconomy. This course will first introduce students to the common tools that macroeconomists use, as well as sources of macro data. Then we will consider aggregate supply, aggregate demand and macroeconomic equilibrium. The rest of the course will discuss the components of GDP such as consumption, investment and government sector. The material that we covered will be supplemented with Harvard Business Cases, classroom experiments and other empirical exercises.
