Temporary partial expensing in a general-equilibrium model
This paper uses a dynamic general-equilibrium model with a nominal tax system to consider the effects of temporary partial expensing allowances on investment and other macroeconomic aggregates.

Real-time properties of the Federal Reserve's output gap
This note considers the reliability of Federal Reserve Board staff estimates of the output gap after the mid-1990s, and examines the usefulness of these estimates for inflation forecasting. Over this period, we find that the Federal Reserve's output gap is more reliably estimated in real time than previous studies have documented for earlier periods and alternative estimation techniques. In contrast to previous work, we also find no deterioration in forecast performance when inflation projections are conditioned on real-time estimates of the output gap.

Inflation measurement
Inflation measurement is the process through which changes in the prices of individual goods and services are combined to yield a measure of general price change. This paper discusses the conceptual framework for thinking about inflation measurement and considers practical issues associated with determining an inflation measure's scope; with measuring individual prices; and with combining these individual prices into a measure of aggregate inflation. We also discuss the concept of "core inflation," and summarize the implications of inflation measurement for economic theory and policy.

New tests of the New-Keynesian Phillips curve
Is the observed correlation between current and lagged inflation a function of backward-looking inflation expectations, or do the lags in inflation regressions merely proxy for rational forward-looking expectations, as in the new-Keynesian Phillips curve? Recent research has attempted to answer this question by using instrumental variables techniques to estimate "hybrid" specifications for inflation that allow for effects of lagged and future inflation. We show that these tests of forward-looking behavior have very low power against alternative, but non-nested, backward-looking ...

The Anatomy of Single-Digit Inflation in the 1960s
Recently, the experience of the 1960s—when the U.S. inflation rate rose rapidly and persistently over a comparatively short period—has been invoked as a cautionary tale for the present. An analysis of this period indicates that the inflation regime that prevailed in the 1960s was different in several key regards from the one that prevailed on the eve of the pandemic. Hence, there are few useable lessons to be drawn from this experience, save that monetary policymaking remains a difficult undertaking.

Taxation and the Taylor principle
We add a nominal tax system to a sticky-price monetary business cycle model. When nominal interest income is taxed, the coefficient on inflation in a Taylor-type monetary policy rule must be significantly larger than one in order for the model economy to have a determinate rational expectations equilibrium. When depreciation is treated as a charge against taxable income, an even larger weight on inflation is required in the Taylor rule in order to obtain a determinate and stable equilibrium. These results have obvious implications for assessing the historical conduct of monetary policy.

(Re-)Connecting Inflation and the Labor Market: A Tale of Two Curves
We propose an empirical framework in which shocks to worker reallocation, aggregate activity, and labor supply drive the joint dynamics of labor market outcomes and inflation, and where reallocation shocks take two forms depending on whether they result from quits or from job loss. In order to link our approach with previous theoretical and empirical work, we extend the procedure for estimating a Bayesian sign-restricted VAR so that priors can be directly imposed on the VAR's impact matrix. We find that structural shocks that shift the Beveridge curve have different effects on inflation. ...

Does the labor share of income drive inflation?
Woodford (2001) has presented evidence that the new-Keynesian Phillips curve fits the empirical behavior of inflation well when the labor income share is used as a driving variable, but fits poorly when deterministically detrended output is used. He concludes that the output gap--the deviation between actual and potential output--is better captured by the labor income share, in turn implying that central banks should raise interest rates in response to increases in the labor share. We show that the empirical evidence generally suggests that the labor share version of the new-Keynesian ...

Should monetary policy target labor's share of income?
In recent work, Woodford (2001) presents evidence that using real unit labor costs (labor's share of income) as a driving variable in the new-Keynesian Phillips curve yields a superior fit for inflation relative to a model that uses deterministically detrended real GDP. This evidence leads him to conclude that the output gap the deviation between actual and potential output is better captured by the labor income share, in turn implying that the monetary authority should raise interest rates in response to increases in this variable. We document that the empirical case for the superiority of ...

A note on the cointegration of consumption, income, and wealth
Lettau and Ludvigson (2001) argue that a log-linearized approximation to an aggregate budget constraint predicts that log consumption, assets, and labor income will be cointegrated. They conclude that this cointegrating relationship is present in U.S. data, and that the estimated cointegrating residual forecasts future asset growth. This note examines whether the cointegrating relationship suggested by Lettau and Ludvigson's theoretical framework actually exists. We demonstrate that we cannot reject the hypothesis that cointegration is absent from the data once we employ measures of ...
