We analyze the effect of inflation on the average output of monopolistic firms facing a small fixed cost of changing nominal prices. Using Taylor expansions, we derive a general closed-form solution for the slope of the long-run Phillips curve. This very simple, unifying formula allows us to...

We analyze the dynamics of inflation in an economy characterized by a forward-looking, staggered, price and wage determination process, and by monetary accommodation. In our model, inflation reconciles the conflicting claims of workers and firms. The model is capable of generating a positive...

In this paper, we consider whether there are lessons to be drawn from the experience of the American economy during the 1930's for the current European situation. The comparison reveals some important differences: In particular, the persistence of American unemployment in the 1930's reflected to...

The Phillips curve was init-ally formulated as a relationship between the rate of change and unemployment, yet what matters for stabilization policy is the rate of inflation, not the rate of wage change. This paper provides new estimates of Phillips curves for both prices and wages extending...
