This paper considers the role of state-contingent inflation as a fiscal shock absorber in an economy with nominal rigidities. I study the Ramsey equilibrium in a monetary model with distortionary taxation, nominal non-state-contingent debt, and sticky prices. With sticky prices, the Ramsey planner

of optimal inflation targeting in a new theoretical framework, which conciliates the interaction between the degree of price stickiness, and the degree of strategic complementarities in firms ’ price setting. We show that adopting a target for inflation, crucially depends on the sequential but complementary

In the U.S. and Europe, prices change somewhere between every six months and once a year. Yet nominal macro shocks seem to have real effects lasting well beyond a year. “Sticky information ” models, as posited by Sims (2003), Woodford (2003) and Mankiw and Reis (2002), can reconcile micro

This paper examines a model of dynamic price adjustment based on the assumption that information disseminates slowly throughout the population. Compared with the commonly used sticky-price model, this sticky-information model displays three related properties that are more consistent with accepted

I offer a macroeconomic view of product markets that combines the desirable properties of the market-clearing models descended from the real business cycle model, on the one hand, and the sticky-price disequilibrium model of modern inflation analysis, on the other hand. I adhere strictly

The New Keynesian Model (NKMl, in its various versions, is the most commonly used instrument for monetary policy analysis. The reason of its success Bes in the mix of assumptions used in building the model. On the one hand, the NKM combines elements of dynamic
