The relative prices of different categories of consumption goods have been trending over time. Assuming they are exogenous with respect to monetary policy, these trends imply that monetary policy cannot stabilize the prices of all consumption categories. If prices are sticky, monetary policy...

Optimal monetary policy maximizes welfare, given frictions in the economic environment. Constructing a model with two sets of frictions - the Keynesian friction of costly price adjustment by imperfectly competitive firms and the Monetarist friction of costly exchange of wealth for goods - we...

Relative prices of some goods or sectors have long-run trends: For example, the price of services relative to goods has been rising fairly steadily for decades. Other relative prices do not have long-run trends but sometimes fluctuate dramatically from one period to the next. How should monetary...

Optimal monetary policy maximizes the welfare of a representative agent, given frictions in the economic environment. Constructing a model with two sets of frictions -- costly price adjustment by imperfectly competitive firms and costly exchange of wealth for goods -- we find optimal monetary...

We study discretionary equilibrium in the Calvo pricing model for a monetary authority that chooses the money supply, producing three main contributions. First, price‐adjusting firms have a unique equilibrium price for a broad range of parameterizations, in contrast to earlier results for the...
