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

This course is on the topic of unemployment. It develops a matching model of the unemployment to study labor market fluctuations; job rationing; efficient unemployment and unemployment gap; and labor market policies such as public employment and unemployment insurance.

This minicourse presents basic facts about business cycles. It then develops a matching model to explain these 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.
