Core inflation

To improve Fed policy, improve communications

Since May 2021, we have criticized the Federal Reserve’s lagging response to surging inflation. In our view, both policy and communications were inadequate to address the looming challenge. Early this year, we argued that the Fed created a policy crisis by refusing to acknowledge the rise of trend inflation, maintaining a hyper-expansionary policy well after trend inflation reached levels far above their 2% target, and failing to articulate a credible low-inflation policy.

Against this background, we commend the FOMC for its recent efforts. Not only is policy moving quickly in the right direction, but communication improved markedly. In particular, despite the increasing likelihood of a near-term recession, Chair Powell made clear that price stability is necessary for achieving the second part of the Fed’s dual mandate. We suspect that the combination of the Fed’s recent promise to make policy restrictive, along with its improved communications, is playing a key role in anchoring longer-term inflation expectations.

In this post, we focus on central bank communication and its link to policy setting. By far the most important goal of communication is to clarify the authorities’ reaction function: the systematic response of central bank policy to prospective changes in key economy-wide fundamentals—usually inflation and the unemployment rate.

To anticipate our conclusions, we argue for two changes to the FOMC’s quarterly Summary of Economic Projections to better illuminate the Committee reaction function. First, we encourage publication of more detail on individual participants’ responses to link individual projections of inflation, economic growth, and unemployment to the path of the policy rate. Second, we see a role for scenario analysis in which FOMC participants provide their anticipated policy path contingent on one or more adverse supply shocks that present unappealing policy tradeoffs (for example, between the speed of returning inflation to its target and the pace at which the unemployment rate returns to its sustainable level)….

The Costs of Acting Too Little, Too Late

Central bankers that act too little too late risk inflation, recession, or both. Everyone, including the members of the Federal Open Market Committee, knows that the FOMC is late in its current campaign to restore price stability. This makes it essential that they do not do too little.

In this post, we highlight the continued gap between the lessons of past disinflations and the Fed’s hopes and aspirations. We find it difficult to square the FOMC’s latest projections of falling inflation with only modest policy restraint. Simply put, we doubt that the peak projected policy rate from the June Summary of Economic Projections (SEP) will be sufficient to lower inflation to 2% in the absence of a recession.

In our view, boosting the credibility of the FOMC’s price stability commitment will require not only greater realism, but a clarification of how policy would evolve if, as in past large disinflations, the unemployment rate rises by several percentage points. The overly sanguine June SEP simply does not address this key question. Indeed, no FOMC participant anticipates the unemployment rate to rise above 4½% over the forecast horizon….

Harry Potter's Monetary Policy Wand?

The Federal Open Market Committee (FOMC) is reassuring us that, so long as we are patient, price stability will return without further pain. But its narrative seems less grounded in historical experience and more like something Harry Potter might have conjured at Hogwarts. By the end of 2024, the Committee expects trend inflation (measured by the price index of personal consumption expenditures excluding food and energy) to drop by more than 3 percentage points while economic growth remains above (and the unemployment rate below) its sustainable level. And, all this magic materializes with the real (inflation-adjusted) policy rate barely turning positive.

The principal means by which the Fed affects the inflation outlook is by influencing financial conditions. Yet, having telegraphed its policy shift for months, the FOMC’s most recent actions on March 16—initiating a series of rate hikes and suggesting that balance sheet tapering could begin soon—barely affected the ease with which firms and households obtain financing. And, while financial conditions are indeed a bit tighter than six months ago—when about one-half of FOMC participants anticipated no interest rate hikes in 2022—these conditions remain quite accommodative (see here).

Is the FOMC’s current policy path consistent with its longer-term price stability goals? In this post, we address this question by exploring policymakers’ newly published projections. Our conclusion is that bringing the inflation trend back to 2% will require a tightening of financial conditions significantly beyond what the Fed currently envisions….

Talking about Tapering

In May, we argued that the FOMC needed to communicate its contingency plans for what they would do should the recent inflation pickup prove more stubborn than its members expect. Such transparency makes it more likely that financial markets will respond to incoming data rather than to policymakers’ actions. By clearly laying out their reaction function, central bankers can avoid disruptions like market taper tantrums.

In June, the FOMC began to remove the self-imposed communication shackles designed to encourage “lower for longer” interest rate expectations and address inflation risks more openly. Indeed, as the above citation from Chairman Powell indicates, at their June meeting, policymakers began to lay the groundwork for scaling back their large-scale asset purchases (LSAPs).

In this post, we start by highlighting how recent Fed communication (which reveals appropriate humility about inflation projections) has helped avoid a market tantrum so far. Along the way, we discuss the various means that FOMC participants have used to express their changing views about the timing of interest rate increases (“liftoff”), even as they make clear that tapering their asset purchases will come first….

Inflation: Don't Worry, Be Prepared

Everyone seems to be worried about inflation (see here and here). People also are concerned that the rising media salience of inflation could raise inflation expectations, leading to a sustained rise in inflation itself.

April price readings certainly boosted these worries: the conventional measure of core inflation—the CPI excluding food and energy—rose by nearly 3% from a year ago, the biggest gain since 1995. Fed Vice Chair Richard Clarida summed up the nearly universal reaction when he said: “I was surprised. This number was well above what I and outside forecasters expected.”

The experience of the high-inflation 1970s makes people prone to worrying about such things. Our reaction is different. After all, worry alone is not going to prevent a sustained pickup of inflation. Only credible anti-inflationary monetary policy can do that. To ensure that inflation expectations remain low, it is up to the central bank to make sure everyone understands how policy will respond if the latest elevated inflation readings prove to be more than temporary. As we have written before, the key is effective communications, not premature action….

The Price is Not Right: Measuring Inflation in a Pandemic

Are prices really plummeting? If you watch the official government gauge of prices in the economy, you would think so. Between March and April, the Consumer Price Index (CPI) dropped by 0.8 percent―that’s a decline of 9.1 percent at an annual rate! Even if we exclude food and energy, prices still fell at half that rate. And, both price measures already had begun to fall the previous month. Is this the new trend? Are we in the midst of a deflation? The short answer is no.

The pandemic is an enormous shock to both supply and demand (see our earlier post). The productive capacity of the economy is lower both now (with the lockdown) and in the medium term (with the need to make economic activity biologically safer). Similarly, demand is lower both temporarily while people stay at home and in the longer term as the propensity to save rises to enable people to pay off elevated debts and build precautionary buffers. Determining which of these shifts prevails is essential for policymakers. If the demand contraction dominates, then trend inflation will fall and policymakers will need to implement further expansionary policies. Conversely, if trend inflation rises (implying that the supply constraints prevail), then policymakers will eventually need to introduce restraint.

In this post, we discuss the difficulties of measuring inflation during a pandemic—when demand and supply both shift dramatically. Our conclusion is that some indices provide better high-frequency signals of the trend. Unsurprisingly, headline measures of inflation are especially poor. Yet, traditional measures of “core inflation” that exclude food and energy may be equally bad. Instead, we suggest focusing on the “trimmed mean,” a statistical construct that disregards all goods and services whose prices change by the largest amounts (either up or down). In recent months, the trimmed mean CPI shows suggest that inflation has edged lower, but remains between 1½ and 2 percent per year….

Measuring inflation: Signal extraction redux

Not long ago, we posted a commentary discussing the difficulty of interpreting GDP data. The problem is one of extracting the true signal of economic growth from the noisy way that we measure output.

This signal extraction problem is generic in economics (and other sciences that use statistics). Indeed, one of us began his professional career trying to discern the trend of U.S. inflation. It was 1980 and the inflation numbers were hitting a peak of nearly 20%. The standard operating procedure at the time was to take things like food, energy and some housing-related items out of the index and recalculate them. But that meant removing only the components that had gone up more than average! How could you justify that?
