Stargazers hate clouds. Even modest levels of humidity and wind make it hard to “see” the wonders of the night sky. Very few places on our planet have consistently clear, dark skies.
Central bankers face a similar, albeit earthly, challenge. Even the simplest economic models require estimation of unobservable factors; something that generates considerable uncertainty. As Vice Chairman Clarida recently explained, the Fed depends on new data not only to assess the current state of the U.S. economy, but also to pin down the factors that drive a wide range of models that guide policymakers’ decisions.
In this post, we highlight how the Federal Open Market Committee’s (FOMC’s) views of two of those “starry” guides—the natural rates of interest (r*) and unemployment (u*)—have evolved in recent years. Like sailors under a cloudy sky, central bankers may need to shift course when the clouds part, revealing that they incorrectly estimated these economic stars. The uncertainty resulting from unavoidable imprecision not only affects policy setting, but also complicates policymakers’ communication, which is one of the keys to making policy effective….

Last month, interrupting decades of presidential self-restraint, President Trump openly criticized the Federal Reserve. Given the President’s penchant for dismissing valuable institutions, it is hard to be surprised. Perhaps more surprising is the high quality of his appointments to the Board of Governors. Against that background, the limited financial market reaction to the President’s comments suggests that investors are reasonably focused on the selection of qualified academics and individuals with valuable policy and business experience, rather than a few early-morning words of reproof.
Nevertheless, the President’s comments are seriously disturbing and—were they to become routine—risk undermining the significant benefits that Federal Reserve independence brings. Importantly, the criticism occurred despite sustained strength in the economy and financial markets, and despite the stimulative monetary and fiscal policies in place…. Read More
Economists have debated the relationship between inflation and unemployment at least since A.W. Phillips’s study of U.K. data from 1861 to 1957 was published 60 years ago. The idea that a tight or slack labor market should result in faster or slower wage gains seems like a natural corollary to standard economic thinking about how prices respond to deviations of demand from supply. But, over the years, disputes about this Phillips curve relationship have been and remain fierce.
As the U.S. labor market tightens, and unemployment approaches levels we have not seen in more than 15 years, the question is whether inflation is going to make a comeback. More broadly, how useful is the Phillips curve as a guide for Federal Reserve policymakers who wish to achieve a 2-percent inflation target over the long run?
To anticipate our conclusion, despite evidence of a negative relationship between wage inflation and unemployment, central banks ought not rely on a stable Phillips curve for setting monetary policy. Read More
“Unfortunately, we have as yet devised no method to estimate accurately and readily the natural rate of either interest or unemployment. And the ‘natural’ rate itself will change from time to time.” Milton Friedman, American Economic Association Presidential Address, 1968.
What do you do if, on a dark and foggy night, you are forced to drive on a road with a sheer cliff on one side? Unless you know precisely where the road ends and the cliff begins, you will likely go slowly and keep your foot near the brakes. Driving like a tortoise is not the “first best” solution – fog lights that distinguish the road from the cliff would be better. But, absent proper illumination, going slowly is a safe response to perilous driving conditions. It helps prevent catastrophic, irreversible errors.
Such robust strategies are key to central bankers' success as well... Read More
