Nonresponse Imputations and Related Measurement Issues in the CPI for Shelter
Shelter is the largest component of US consumer price index (CPI) inflation; therefore, the accuracy of shelter inflation is critical for the accuracy of overall CPI inflation. Nonresponse in the BLS Housing Survey, which underpins the measurement of CPI shelter inflation, has increased since 2000 and now represents roughly 40 percent of total observations. Missing rent data are currently imputed using a class-mean approach based on rent tier, potentially resulting in biased imputations, as we find that nonresponse is correlated with factors beyond rent tier. We study alternative simple ...

Tracking Trend Inflation: Nonseasonally Adjusted Variants of the Median and Trimmed-Mean CPI
We make five contributions. We demonstrate that extant trimmed-mean and median CPI construction procedures depart from Bureau of Labor Statistics index construction procedures, and that the departures don't make much of a difference. We produce nonseasonally adjusted variants of the trimmed-mean CPI and median CPI, and demonstrate that these are useful real-time estimates of trend inflation; the NSA median CPI outperforms the median CPI, but both SA and NSA variants of the median and the trimmed-mean CPI easily dominate the so-called "core" CPI. We introduce superior ex post measures of trend ...

Persistence Dependence in Empirical Relations: The Velocity of Money
Standard theory predicts persistence dependence in numerous economic relationships. (For example, persistence dependence is precisely the kind of nonlinear relationship posited in the Permanent Income Hypothesis; persistence dependence is the inverse of ?frequency dependence? in a relationship.) Until recently, however, it was challenging to achieve credible inference about persistence dependence in an economic relationship using available methods. However, recently developed econometric tools (Ashley and Verbrugge, 2009a) allow one to elegantly quantify the variation in a time-series ...

Improving the Median CPI: Maximal Disaggregation Isn't Necessarily Optimal
Median Consumer Price Indexes have proved useful in many contexts and are used worldwide as key policymaking inputs. Historically, US Median CPI improvements involved increasing the CPI component level of disaggregation; one might reasonably assume that further disaggregation would lead to further improvements. We theoretically demonstrate herein: not necessarily. We then empirically explore the impact of further disaggregation. Substantially more disaggregation in the shelter indexes and slightly more disaggregation in the remaining components improve the ability of Median CPI to track the ...

How Much Slack Is in the Labor Market? That Depends on What You Mean by Slack
Estimates of labor market slack can diverge a great deal depending on how slack is defined. We calculate slack using five different concepts that all focus on a single labor market indicator, the unemployment rate. We show that the estimates all provide useful?but different?information. We argue that choosing the best measure of slack depends on the question being asked. If the question is, ?Has the unemployment rate reached its longer-run normal level?? then our answer is, ?Almost.? But significant uncertainty surrounds the estimates; and others may wish to consider additional labor market ...

Frequency Dependence in a Real-Time Monetary Policy Rule
We estimate a monetary policy rule for the US allowing for possible frequency dependence?i.e., allowing the central bank to respond differently to more persistent innovations than to more transitory innovations, in both the unemployment rate and the inflation rate. Our estimation method uses real-time data in these rates?as did the FOMC?and requires no a priori assumptions on the pattern of frequency dependence or on the nature of the processes generating either the data or the natural rate of unemployment. Unlike other approaches, our estimation method allows for possible feedback in the ...

Sticky Rents: A Simple Implicit-Contracts Theory
Shelter inflation, driven by continuing-tenant rents, accounts for one-third of the consumer price index (CPI). Yet continuing-tenant rent inflation, notoriously sticky, has attracted almost no theoretical attention. Standard sticky price theories cannot explain the basic facts. We provide a simple theory yielding implicit contracts as an equilibrium. The landlord will wish to renege when costs rise; reputation is unavailable to enforce the contract. A well-established mechanism serves: landlord off-equilibrium-path play might result in renter frustration and endogenous breakup. Our ...

Determinants of Differential Rent Changes: Mean Reversion versus the Usual Suspects
We study 2001-2004 and 2004-2007 rent growth of 18,000 rental units, ending our study prior to the Great Recession. Which variables correlate with rent growth: Location? Age? Rent level? Occupancy duration? Structure type? The answers deepen understanding of the rental market, help statistical agencies make decisions about sample stratification and substitution, and expose coverage problems. We document significant rent stickiness. Initial relative rent level is the best predictor, though mainly due to mean reversion. "Location" comes in second, though often not statistically significantly: ...

Location, Location, Structure Type: Rent Divergence within Neighborhoods
Housing rents are a large share of household budgets and make a large contribution to overall inflation. Rent inflation rates for different types of housing units sometimes diverge, even in the same neighborhoods. We estimate during 2013 to 2016 apartment rents outpaced rents for detached housing in the United States by 0.76 percentage points annually after controlling for location effects. These rent dynamics imply a segmented housing market. They also suggest rent indexes need to be based on data structurally representative of their measurement objective. In particular, indexes based on ...

Improving the Median CPI: Maximal Disaggregation Isn't Necessarily Optimal
For decades, the Federal Reserve Bank of Cleveland (FRBC) has produced the Median Consumer Price Index (CPI). It has proven useful in various contexts, such as forecasting and understanding post-COVID inflation dynamics. Historically, revisions/improvements to the FRBC methodology have involved increasing the level of disaggregation in the CPI components. Thus, it may be reasonable to assume that further disaggregation improves the properties of the median CPI. We theoretically demonstrate: not necessarily. We then empirically explore the impact of further disaggregation by examining fifteen ...
