Real-time model uncertainty in the United States: 'Robust' policies put to the test
I study 46 vintages of FRB/US, the principal macro model used by Federal Reserve Board staff for forecasting and policy analysis, as measures of real-time model uncertainty. I also study the implications of model uncertainty for the robustness of commonly applied, simple monetary policy rules. I first document that model uncertainty poses substantial challenges for policymakers in that key model properties differ in important ways across model vintages. Then I show that the parameterization of optimized simple policy rule--rules that are intended to be robust with respect to model ...

The Federal Reserve's framework for monetary policy - recent changes and new questions
In recent years, the Federal Reserve has made substantial changes to its framework for monetary policymaking by providing greater clarity regarding its objectives, its intentions regarding the use of monetary policy--including nontraditional policy tools such as forward guidance and asset purchases--in the pursuit of those objectives, and its broader policy strategy. These changes reflected both a response to changes in economists' understanding of the most effective way to implement monetary policy and a response to specific challenges posed by the financial crisis and its aftermath, ...

Optimal policy projections
We outline a method to provide advice on optimal monetary policy while taking policymakers' judgment into account. The method constructs optimal policy projections (OPPs) by extracting the judgment terms that allow a model, such as the Federal Reserve Board staff economic model, FRB/US, to reproduce a forecast, such as the Greenbook forecast. Given an intertemporal loss function that represents monetary policy objectives, OPPs are the projections---of target variables, instruments, and other variables of interest---that minimize that loss function for given judgment terms. The method is ...

Avoiding Nash inflation: Bayesian and robust responses to model uncertainty
In his 1999 monograph The Conquest of American Inflation Tom Sargent describes how a policymaker, who applies a constant-gain algorithm in estimating the Phillips curve, can fall into the grip of an induction problem: concluding on the basis of reduced-form evidence that the trade-off between inflation and output is more favorable than it actually is. This results in oscillations between periods of disinflation and reflation. The problem arises because the policymaker is naive about possible misspecification, her role in creating that misspecification, and its role in policy design. In ...

The Monetary Policy Response to Uncertain Inflation Persistence
This FEDS Note considers the implications of uncertainty regarding the persistence of inflation for the conduct of monetary policy.

Avoiding Nash Inflation : Bayesian and Robust Responses to Model Uncertainty
We examine learning, model misspecification, and robust policy responses to misspecification in a quasi-real-time environment. The laboratory for the analysis is the Sargent (1999) explanation for the origins of inflation in the 1970s and the subsequent disinflation. Three robust policy rules are derived that differ according to the extent that misspecification is taken as a parametric phenomenon. These responses to drifting estimated parameters and apparent misspecification are compared to the certainty-equivalent case studied by Sargent. We find gains from utilizing robust approaches to ...

The Macroeconomic Implications of CBDC: A Review of the Literature
This paper provides an overview of the literature examining how the introduction of a CBDC would affect the banking sector, financial stability, and the implementation and transmission of monetary policy in a developed economy such as the United States. A CBDC has the potential to improve welfare by reducing financial frictions in deposit markets, by boosting financial inclusion, and by improving the transmission of monetary policy. However, a CBDC also entails noteworthy risks, including the possibility of bank disintermediation and associated contraction in bank credit, as well as potential ...

Aggregate disturbances, monetary policy, and the macroeconomy: the FRB/US perspective
The FRB/US macroeconometric model of the U.S. economy was created at the Federal Reserve Board for use in policy analysis and forecasting. This article begins with an examination of the model's characterization of the monetary transmission mechanism -- the chain of relationships describing how monetary policy actions influence financial markets and, in turn, output and inflation. The quantitative nature of this mechanism is illustrated by estimates of the effect of movements in interest rates and other factors on spending in different sectors and by simulations of the effect of a change in ...

Financial stress and economic dynamics: the transmission of crises
The recent financial crisis and the associated decline in economic activity have raised some important questions about economic activity and its links to the financial sector. This paper introduces an index of financial stress--an index that was used in real time by the staff of the Federal Reserve Board to monitor the crisis--and shows how stress interacts with real activity, inflation and monetary policy. We define what we call a stress event--a period affected by stress in both shock variances and model coefficients--and describe how financial stress affects macroeconomic dynamics. We also ...
