In this paper, we propose a simple econometric framework to disentangle the respective roles of monetary policy inertia and persistent shocks in interest rate rules. The procedure exploits the cross-equation restrictions provided by a DSGE model which is confronted to a monetary SVAR. We show...

This paper proves in a New Keynesian model that interest rate pegging can explain the unusual business cycle fluctuations in China. It is traditional wisdom that when the nominal interest rate is inflexible, there is no unique equilibrium in macroeconomic models. We prove that a unique...

This note deals with the stability properties of an economy where the central bank is concerned with stock market developments. We introduce a Taylor rule reacting to stock price growth rates along with inflation and output gap in a New-Keynesian setup. We explore the performance of this rule...

In this paper, we structurally model uncertainty with a micro-founded model, and investigate its implications for optimal monetary policy. Uncertainty about deep parameters of the model implies that the central bank simultaneously faces both uncertainty about the structural dynamic equations and...

We investigate the implications of rule-of-thumb behaviour on the part of consumers or price setters for optimal monetary policy and simple interest rate rules. The existence of such behaviour leads to endogenous persistence in output and inflation; changes the transmission of shocks to these...

This paper examines the role of the natural rate of interest in the conduct of monetary policy. The natural rate figures prominently in many theories of the business cycle and of inflation fluctuations, and therefore has the potential to play a key role in monetary policy given the current...

We study the welfare performance of various simple monetary policy rules under bounded rationality (BR) along the lines of Gabaix (2020) in a New Keynesian model with sticky wages and an effective lower bound (ELB) on interest rates. Policy strategies with a strong history dependence lose their...

We investigate the implications of rule-of-thumb behaviour on the part of consumers or price setters for optimal monetary policy and simple interest rate rules. The existence of such behaviour leads to endogenous persistence in output and inflation; changes the transmission of shocks to these...
