This paper builds a Beveridgean model of the Phillips curve. Prices respond to slack so the divine coincidence holds: prices are stable at full employment. The Phillips curve is kinked if wage cuts are more costly to producers than price hikes.
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 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 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.
