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 ...

Can rational expectations sticky-price models explain inflation dynamics?
The canonical inflation specification in sticky-price rational expectations models (the new-Keynesian Phillips curve) is often criticized on the grounds that it fails to account for the dependence of inflation on its own lags. In response, many recent studies have employed a "hybrid" sticky-price specification in which inflation depends on a weighted average of lagged and expected future values of itself, in addition to a driving variable such as the output gap. In this paper, we consider some simple tests of the hybrid model that are derived from the model's closed-form solution. Our ...

On the relationships between real consumption, income and wealth
The existence of durable goods implies that the welfare flow from consumption cannot be directly associated with total consumption expenditures. As a result, tests of standard theories of consumption (such as the Permanent Income Hypothesis, or PIH) typically focus on nondurable goods and services. Specifically, these studies generally relate real consumption of nondurable goods and services to measures of real income and wealth, where the latter are deflated by a price index for total consumption expenditures. We demonstrate that this procedure is only valid under the assumption that real ...

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 ...

(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 the labor market and inflation, and where reallocation shocks take two forms depending on whether they result from quits or from job losses. We find that these structural shocks, which affect the Beveridge curve, have different effects on inflation. Our model fully decomposes shifts of or along the empirical Beveridge curve in terms of the contribution of each shock and also allows us to estimate the Phillips correlation associated with each shock; ...
