Abstract

We provide a microfounded account of imperfect information in the stochastic growth model which dramatically changes the properties of the model. We describe heterogenous households that acquire information about aggregates through their participation in markets. If markets are incomplete, household information will be imperfect. We solve the model taking account of the infinite regress of expectations that this lack of information implies. We derive analytical and numerical results to show that imperfect information can significantly change the properties of the model: under virtually all calibrations the impact response of consumption to a positive aggregate technology shock is negative.
