We propose a model that reconciles microeconomic evidence of frequent and large price
changes with sizable monetary non-neutrality. Firms incur separate lump-sum costs to
change prices and to gather and process some information about marginal costs. Additional relevant information is continuously available, and can be factored into pricing
decisions at no cost. We estimate the model by Simulated Method of Moments, using
price-setting statistics for the U.S. economy. The model with free idiosyncratic and costly
aggregate information fits well both targeted and untargeted microeconomic moments and
generates almost three times as much monetary non-neutrality as the Calvo model.
