Assessing Simple Policy Rules: A View from a Complete Macro Model
نویسندگان
چکیده
We explore two popular approaches to empirical analysis of monetary policy: the New Keynesian and the identified vector autoregression approaches. Stylized models of private behavior coupled with simple rules describing policy behavior characterize New Keynesian work. Vector autoregressions consist of minimally identified dynamic descriptions of private behavior coupled with a detailed rule for policy behavior. The simplicity of New Keynesian models aids in communication but leaves the models’ implications vulnerable. By relating the New Keynesian models to identified vector autoregressions, we explore the differences and similarities in the two approaches and assess some of the key conclusions to emerge from New Keynesian research. JEL classification: E52, E47, C53

Monetary and Macro-prudential Policies: An Integrated Analysis
This paper studies the interaction between monetary and macro-prudential policies in a simple model with both nominal and financial frictions. The nominal friction gives rise to a conventional monetary policy objective emphasized in the New Keynesian literature. The financial friction, in the form of an occasionally binding collateral constraint, gives rise to a financial stability objective. ...
متن کاملOptimal Macro-Prudential and Monetary Policy∗
This paper addresses two main questions. First, it examines the implications of financial frictions, embedded in a New Keynesian DSGE model with a banking sector, for the conduct of welfare-optimal monetary policy. Assuming only one monetary instrument, we analyse how financial frictions affect the gains from commitment and how different are the optimized simple rules with and without financial...
متن کاملExact Utilities under Alternative Monetary Rules in a Simple Macro Model with Optimizing Agents
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 contracts are signed. We evaluate alternative monetary policy rules using the utility function of the rep...
متن کاملAssessing Simple Policy Rules: A View from a Complete Macroeconomic Model
stories frequently dominates the desire to fit data. This is not a choice between " simple " and " complex " though it is sometimes couched as such. A model must be simple if it's to be understood. It must be understood if it's to inform policy debates. Unfortunately, we understand models on a qualitative level, while we use them for policy analysis on a quantitative level. Tensions arise in mo...
متن کاملNecessary but Not Sufficient…; Comment on “Knowledge Mobilization in Healthcare Organizations: A View From the Resource-Based View of the Firm”
The challenge of mobilizing knowledge to improve patient care, population health and ensure effective use of resources is an enduring one in healthcare systems across the world. This commentary reflects on an earlier paper by Ferlie and colleagues that proposes the resource-based view (RBV) of the firm as a useful theoretical lens through which to study knowledge mobilization in healthcare.
