Predetermined Prices and the Persistent Effects of Money on Output

This Paper illustrates a model of predetermined pricing based on the work of Fischer (1977), where firms set a fixed schedule of nominal prices at the time of price readjustment. This type of price-setting specification cannot produce any excess persistence in a fixed duration model of staggered prices. But we show that with a probabilistic model of price adjustment, as in Calvo (1983), a predetermined pricing specification can produce excess persistence. Moreover, in response to a money shock, the aggregate dynamics are very similar to those under a specification of fixed prices, the assumption underlying most recent dynamic sticky-price models.
