Using annual US data for gross domestic product originating by sector between 1947 and 1997 it is shown that a negative long-run relationship between inflation and the markup is present across the sectors as well as in the aggregate. A preliminary explanation based on indutry structure is...

This paper considers a sticky price model with a cash-in-advance constraint where agents forecast inflation rates by fitting econometric models to data. Agents are uncertain about which model to fit and can choose from a class of models. Only some of the models in this class are consistent with...
