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 government spending should be designed to tame business cycles.
This graduate course presents various matching models of economic slack. It uses them to study business-cycle fluctuations; Keynesian, classical, and frictional unemployment; optimal monetary policy and the zero lower bound; and optimal government spending.
This paper develops a policy-oriented business-cycle model with fluctuating unemployment and long zero-lower-bound episodes. The innovations are that producers and consumers meet through a matching function, and wealth enters the utility function.
This paper develops a model of pricing in which buyers care about the fairness of markups but misinfer them from prices. The model yields price rigidity, generates realistic Phillips curves, and explains why people dislike inflation so much.
This paper resolves the anomalies of the New Keynesian model at the zero lower bound—explosive recession, forward guidance puzzle, multiplier puzzle—by introducing wealth into the utility function.
This undergraduate course introduces macroeconomic concepts—such as GDP and inflation—and covers the IS-LM model of business cycles, matching model of unemployment, Phillips curve, Malthusian model of growth, and Solowian model of growth.
