We develop a simple and intuitive approach for analytically deriving unconditionally optimal (UO) policies, a topic of enduring interest in optimal monetary policy analysis. The approach can be employed in both general linear-quadratic problems and in the underlying non-linear environments. A...

We study the impact of two-sided nominal shocks in a dynamic, equilibrium macroeconomic model. Goods complementarity differs across sectors as do the costs of changing prices. Even when strategic complementarities are equal across the sectors, the systematic differences in costs of price...

A key argument in Caplin and Leahy (1997) states that the correlation between monetary shocks and output is falling in the variance of the money supply. We demonstrate that this conclusion depends on solving for the correlation in the nonstationary state of the model. In the stationary state,...

Social welfare objectives are investigated when changing prices is costly (Rotemberg, 1982). A quadratic welfare function is derived, with a distorted steady state, implying inflation and output stabilization goals. Economic distortions influence inflation aversion in a way that differs from...
