Abstract

This paper surveys some recent work in the theory of business cycles, which emphasizes the role of public news and consumer expectations as driving forces behind short-run aggregate fluctuations. The paper uses a simple two period model to introduce and discuss three issues regarding this class of models: (1) what is the role of nominal rigidities, (2) what are the testable implications of these models, (3) what are their implications for monetary policy.
