Real interest rate persistence: evidence and implications
The real interest rate plays a central role in many important financial and macroeconomic models, including the consumption-based asset pricing model, neoclassical growth model, and models of the monetary transmission mechanism. We selectively survey the empirical literature that examines the time-series properties of real interest rates. A key stylized fact is that postwar real interest rates exhibit substantial persistence, shown by extended periods of time where the real interest rate is substantially above or below the sample mean. The finding of persistence in real interest rates is ...

States and the business cycle
We model the U.S. business cycle using a dynamic factor model that identifies common factors underlying fluctuations in state-level income and employment growth. We find three such common factors, each of which is associated with a set of factor loadings that indicate the extent to which each state?s business cycle is related to the national business cycle. According to the factor loadings, there is a great deal of heterogeneity in the nature of the links between state and national economies. In addition to exhibiting interesting geographic patterns, the factor loadings tend to be related to ...

The Anatomy of Out-of-Sample Forecasting Accuracy
We introduce the performance-based Shapley value (PBSV) to measure the contributions of individual predictors to the out-of-sample loss for time-series forecasting models. Our new metric allows a researcher to anatomize out-of-sample forecasting accuracy, thereby providing valuable information for interpreting time-series forecasting models. The PBSV is model agnostic—so it can be applied to any forecasting model, including "black box" models in machine learning, and it can be used for any loss function. We also develop the TS-Shapley-VI, a version of the conventional Shapley value that ...

Is the Last Mile More Arduous?
US inflation surged starting in spring 2021, with Consumer Price Index (CPI) inflation reaching a 40-year high of 9 percent in mid-2022. Together with improving supply-chain conditions, policy tightening by the Fed decreased inflation to within 1 to 2 percentage points of its 2 percent target by late 2023 without a significant increase in unemployment. However, concerns have been raised that the last mile of disinflation to reduce inflation consistently to its 2 percent target will be more arduous than the previous miles. Close examination of such concerns indicates that they do not receive ...

Forecasting real housing price growth in the Eighth District states
The authors consider forecasting real housing price growth for the individual states of the Federal Reserve's Eighth District. They first analyze the forecasting ability of a large number of potential predictors of state real housing price growth using an autoregressive distributed lag (ARDL) model framework. A number of variables, including the state housing price-to-income ratio, state unemployment rate, and national inflation rate, appear to provide information that is useful for forecasting real housing price growth in many Eighth District states. Given that it is typically difficult to ...

Is inflation an international phenomenon?
Common shocks, similarities in central bank reaction functions, and international trade potentially produce common components in international inflation rates. This paper characterizes such links in international inflation rates with a dynamic latent factor model that decomposes inflation for 65 countries into world, regional, and idiosyncratic components. The world component accounts for 34% of inflation variability on average across countries, although the importance of this global factor differs substantially across countries. Variables that reflect policy as well as economic and financial ...

Metro Business Cycles
We construct monthly economic activity indices for the 50 largest U.S. metropolitan statistical areas (MSAs) beginning in 1990. Each index is derived from a dynamic factor model based on twelve underlying variables capturing various aspects of metro area economic activity. To accommodate mixed-frequency data and differences in data-publication lags, we estimate the dynamic factor model using a maximum- likelihood approach that allows for arbitrary patterns of missing data. Our indices highlight important similarities and differences in business cycles across MSAs. While a number of MSAs ...
