vertical aggregate supply curve, the persistence of the real effects of monetary policy, and the difference between idiosyncratic and aggregate shocks. We also compare imperfect information to the other leading model of aggregate supply, sticky prices.
We discuss the foundations on which models of aggregate supply rest, as well as the microfoundations for two classes of imperfect information models: models with partial information, where agents observe economic conditions with noise, and models with delayed information, where they observe economic conditions with a lag.
Imperfect Information and Aggregate Supply N. Gregory Mankiw and Ricardo Reis NBER Working Paper No. 15773 February 2010 JEL No. D8,E1,E3 ABSTRACT This paper surveys the research in the past decade on imperfect information models of aggregate supply and the Phillips curve. This new work has emphasized that information is dispersed and disseminates
This chapter and Romer’s Section 6.9 examine Robert Lucas’s imperfect infor-mation model, which sits at a major crossroads in the evolution of macroeconomic theory. The Lucas model represents macroeconomists’ first voyage into mathemati-cal modeling of a complete monetary-macroeconomic system based on well-specified microeconomic assumptions.
Imperfect-Information Model The imperfect-information model of the upward sloping short- run aggregate supply curve is again based on the labor market. In this model, unlike either the sticky-wage model or the worker-misperception model, neither the worker nor the firm has complete information.
model in which markets are perfectly competitive. As expected, the aggregate-supply curve in this model is perfectly inelastic and changes in money (aggregate demand) have no effect on real variables. A true Lucas model is introduced in Section 6.2 with the introduction of imperfect information into the previous classical model. B.
