This paper develops a simple business-cycle model with divine coincidence: inflation is on target when unemployment is efficient. The divine coincidence arises from directed search under a quadratic price-adjustment cost.
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 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.
