We develop and estimate a structural model of inflation that allows for a fraction of firms that use a backward looking rule to set prices. The model nests the purely forward looking New Keynesian Phillips curve as a particular case. We use measures of marginal cost as the relevant determinant...

We develop a model of state-dependent pricing that we can log-linearize and compare to the standard Calvo model. In one extreme case, money is neutral with state-dependent pricing even though the probability of price adjustment is constant as in the Calvo model. We use this example to illustrate...
