Abstract

Macroeconomic models often invoke consumption "habits" to explain the substantial persistence of macroeconomic consumption growth. to explain the substantial But a large literature has found no evidence of habits in the micro-economic datasets that measure the behavior of individual households. We show that the apparent conflict can be explained by a model in which consumers have accurate knowledge of their personal circumstances but `sticky expectations' about the macro-economy. In our model, the persistence of aggregate consumption growth reflects consumers' imperfect attention to aggregate shocks. Our proposed degree of (macro) inattention has negligible utility costs, because aggregate shocks constitute only a tiny proportion of the uncertainty that consumers face.
