Adjusting Median and Trimmed-Mean Inflation Rates for Bias Based on Skewness
Median and trimmed-mean inflation rates tend to be useful estimates of trend inflation over long periods, but they can exhibit persistent departures from the underlying trend over shorter horizons. In this Commentary, we document that the extent of this bias is related to the degree of skewness in the distribution of price changes. The shift in the skewness of the cross-sectional price-change distribution during the pandemic means that median PCE and trimmed-mean PCE inflation rates have recently been understating the trend in PCE inflation by about 15 and 35 basis points, respectively.

Thinking Outside the Box: Do SPF Respondents Have Anchored Inflation Expectations?
Despite the stability of the median 10-year inflation expectations in the Survey of Professional Forecasters (SPF) near 2 percent, we show that not a single SPF respondent?s expectations have been anchored at the target since the Federal Open Market Committee?s (FOMC) enactment of an inflation target in January 2012, or even since 2015. However, we find significant evidence for ?delayed anchoring,? or a move toward being anchored, particularly after the federal funds rate lifted off in December 2015.

Improving Inflation Forecasts Using Robust Measures
Both theory and extant empirical evidence suggest that the cross-sectional asymmetry across disaggregated price indexes might be useful in the forecasting of aggregate inflation. Trimmed-mean inflation estimators have been shown to be useful devices for forecasting headline PCE inflation. But does this stem from their ability to signal the underlying trend, or does it mainly come from their implicit signaling of asymmetry (when included alongside headline PCE)? We address this question by augmenting a “hard to beat” benchmark inflation forecasting model of headline PCE price inflation ...

Digging into the Downward Trend in Consumer Inflation Expectations
Since mid-2014, the long-run inflation expectations of consumers have been declining. Many commentators blame the decline on gasoline prices, which have also been falling since that time, but we argue that this explanation is incomplete. We analyze University of Michigan Surveys of Consumers microdata and find that a decline in uncertainty about future inflation is a modest part of the story over this period?but it represents the entire story when considering changes in expectations since 2012.

Behavior of a New Median PCE Measure: A Tale of Tails
We introduce two new measures of trend inflation, a median PCE inflation rate and a median PCE excluding OER inflation rate, and investigate their performance. Our analysis indicates that both perform comparably to other simple trend inflation estimators such as the trimmed-mean PCE. Furthermore, we find that the performance of the median PCE is related to skewness in the distribution of cross-sectional growth rates across categories in the PCE, and our results suggest that the Bowley skewness statistic may be useful in forecasting.

A New Tool for Robust Estimation and Identification of Unusual Data Points
Most consistent estimators are what Müller (2007) terms “highly fragile”: prone to total breakdown in the presence of a handful of unusual data points. This compromises inference. Robust estimation is a (seldom-used) solution, but commonly used methods have drawbacks. In this paper, building on methods that are relatively unknown in economics, we provide a new tool for robust estimates of mean and covariance, useful both for robust estimation and for detection of unusual data points. It is relatively fast and useful for large data sets. Our performance testing indicates that our baseline ...

Whose Inflation Expectations Best Predict Inflation?
We examine the predictive relationship between various measures of inflation expectations and future inflation. We find that the expectations of professional economists and of businesses have tended to provide more accurate predictions of future inflation than the expectations of households and of financial market participants. However, the forecasts coming from a relatively simple and popular benchmark inflation forecasting model have historically been roughly as accurate as the expectations of businesses and professional economists.

Finding a Stable Phillips Curve Relationship: A Persistence-Dependent Regression Mode
We establish that the Phillips curve is persistence-dependent: inflation responds differently to persistent versus moderately persistent (or versus transient) fluctuations in the unemployment gap. Previous work fails to model this dependence, so it finds numerous “inflation puzzles”—such as missing inflation/disinflation—noted in the literature. Our model specification eliminates these puzzles; for example, the Phillips curve has not weakened, and inflation is not “stubbornly low” at present. The model’s coefficients are stable, and it provides accurate conditional recursive ...

Federal Funds Rates Based on Seven Simple Monetary Policy Rules
Monetary policymakers often use simple monetary policy rules, like the Taylor rule, as an input into their decision-making. However, there are many different simple rules, and there is no agreement on a single ?best? rule. We look at the federal funds rates coming from seven simple rules and three economic forecasts to investigate the range of results that can be produced. While there are some commonalities, we document that the differences in the federal funds rates suggested by the rules can be quite pronounced.
