This course develops a model of economic slack. The model is used to study business-cycle fluctuations; Keynesian, classical, and frictional unemployment; optimal monetary policy and the zero lower bound; and optimal fiscal policy.

This course develops a model of unemployment. The model is used to study unemployment fluctuations; job rationing; efficient unemployment and unemployment gap; and labor market policies such as minimum wage, public employment, and unemployment insurance.

This minicourse presents basic facts about business cycles. It then develops a matching model to explain these business-cycle facts. Finally, it explains how monetary policy and fiscal policy should be designed to tame business cycles.

This course introduces macroeconomic concepts such as GDP and covers the IS-LM model of business cycles, matching model of unemployment, Phillips curve, Malthusian model of growth, and Solowian model of growth.

This minicourse covers basic mathematical methods for macroeconomics: dynamic programming, optimal control, and differential equations. The methods are used to study dynamical macroeconomic systems in discrete time and continuous time.
