We consider a dynamic stochastic general equilibrium model (DSGE) in which firms follow one of four price‐setting regimes: sticky prices, sticky information, rule of thumb, or full‐information flexible prices. The parameters of the model, including the fraction of each type of firm, are estimated by matching the moments of the observed variables of the model to those found in the data. We find that sticky price firms and sticky information firms jointly account for over 80% of firms in the model. We compare the performance of our hybrid model to pure sticky price and sticky information models along various dimensions, including monetary policy implications.

I consider the empirical evidence for the sticky information model relative to the basic sticky price model, conditional on historical measures of inflation forecasts. The estimated structural parameters are inconsistent with an underlying sticky information model and the sticky information Phillips curve is statistically dominated by the new Keynesian Phillips curve. I find that the poor performance of the sticky information approach is driven by two key elements. First, the sticky information model underestimates inflation in the 1970s and overestimates inflation since the 1980s. Second, predicted inflation from the sticky information model is excessively smooth.
