I study forty-six vintages of FRB/US, the principal macro model used by the Federal Reserve, as measures of real-time model uncertainty and examine the robustness of commonly applied, simple monetary policy rules. Model uncertainty turns out to be a substantial problem: key model properties...

Monetary policy is modeled as being governed by a known rule, except for a time-varying target rate of inflation. The variable target can be thought of either as standing in for discretionary deviations from the rule or as the outcome of a policymaking committee that is unable to arrive at a...

We estimate the path of inflation persistence in the United States over the last fifty years using an ARMA model of inflation with time-varying autoregressive parameter, motivated by the familiar New Keynesian framework. The estimated path of inflation persistence is consistent with a general...

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...
