We construct an optimizing-agent model of a closed economy which is simple enough that we can use it to make exact utility calculations. There is a stabilization problem because there are one-period nominal contracts for wages, or prices, or both and shocks that are unknown at the time when...

Structural estimation of macroeconomic models and new HANK-type models with extremely high dimensionality require fast and robust methods to efficiently deal with occasionally binding constraints (OBCs). This paper proposes a novel algorithm that solves for the perfect foresight path of...

Recently there has been a resurgence of interest in the study of optimal monetary policy under uncertainty. This book provides a thorough survey of the literature that has resulted from this renewed interest. The authors ground recent contributions on the 'science of monetary policy' in the...
