We investigate the ability of monetary policy rules to implement a unique equilibrium outcome when the enforcement of rules is limited. We combine the approach of Bassetto (2005) and Atkeson et al. (2010) to study implementation and the one by Chari and Kehoe (1990) to allow policy deviations....

This paper investigates the ability of monetary policy rules to coordinate private agents' expectations when the enforcement of rules is limited. We show that limited enforcement precludes diverging inflation paths ensuring that nominal variables remain bounded in equilibrium. When applied to...

In this paper, we provide solution methods for non-linear rational expectations models in which regime-switching or the shocks themselves may be "endogenous," i.e. follow state-dependent probability distributions. We use the perturbation approach to find determinacy conditions, i.e. conditions...

This paper studies how private demand for public liquidity affects the independence of a central bank vis-à-vis the fiscal authority. Whereas supplying liquidity to the private sector creates degrees of freedom for fiscal and monetary authorities vis-à-vis each other, we show that the...
