Oil Shocks and Aggregate Macroeconomic Behavior: The Role of Monetary Policy*

A recent paper by Bernanke, Gertler, and Watson (1997) suggests that monetary policy could be used to eliminate any recessionary consequences of an oil price shock. This paper challenges this conclusion on two grounds. First, we question whether the Federal Reserve actually has the power to implement such a policy; for example, we consider it unlikely that additional money creation would have succeeded in reducing the Fed funds rate by 900 basis points relative to the values seen in 1974. Second, we point out that the size of the effect that Bernanke, Gertler, and Watson attribute to oil shocks is substantially smaller than that reported by other researchers, primarily due to their choice of a shorter lag length than that used by other researchers. We offer evidence in favor of the longer lag length employed by previous research and show that under this specification, even the aggressive Federal Reserve policies proposed would not have succeeded in averting a downturn.

OIL PRICE SHOCKS, SYSTEMATIC MONETARY POLICY, AND THE “GREAT MODERATION”

The U.S. economy has experienced a reduction in volatility since the mid-1980s. In this paper we investigate the changes in the response of the economy to an oil price shock and the role of the systematic monetary policy response in accounting for changes in the response of output, prices, inventories, sales, and the overall decline in volatility. Our results suggest a smaller and more short-lived response of most macro variables during the Volcker-Greenspan period. It also appears that whereas the systematic monetary policy response dampened fluctuations in economic activity during the 1970s, it has had virtually no effect after the “Great Moderation.â€

OIL PRICE SHOCKS AND INDUSTRIAL PRODUCTION: IS THE RELATIONSHIP LINEAR?

This paper tests the three leading specifications of asymmetric and possibly nonlinear feedback from the real price of oil to U.S. industrial production and its sectoral components. We show that the evidence for such feedback is sensitive to the estimation period. Support for a nonlinear model is strongest for samples starting before 1973. Instead, using post-1973 data only, the evidence against symmetry becomes considerably weaker. For example, at the aggregate level, there is no evidence against the hypothesis of symmetric responses to oil price innovations of typical magnitude, consistent with results of Kilian and Vigfusson [ Quantitative Economics , 2(3), 419–453 (2011)] for U.S. real GDP. There is strong evidence of asymmetries at the disaggregate level, however, especially for industries that are energy-intensive in production (such as chemicals) or that produce goods that are energy-intensive in use (such as transportation equipment). Our analysis suggests that these asymmetries may be obscured in the aggregate data and highlights the importance of developing multisector models of the transmission of oil price shocks.

The Decline in U.S. Output Volatility: Structural Changes and Inventory Investment

Explanations for the decline in U.S. output volatility since the mid-1980s include: “better policy,” “good luck,” and technological change. Our multiple-break estimates suggest that reductions in volatility since the mid-1980s extend not only to manufacturing inventories, but also to sales. This finding, along with a concentration of the reduction in the volatility of inventories in materials and supplies and the lack of a significant break in the inventory–sales covariance, imply that new inventory technology cannot account for most of the decline in output volatility.

Why So Small? Explaining the Size of Firms in Latin America

On average, Latin American firms are small with respect to world patterns, both in terms of the quantity of assets they control and the amount of employment they generate. We examine data on firm size from developed and developing countries around the world to assess the influence of demand, supply and institutional factors on the size of the largest firms in each country. We find that, besides the size of the economy and the level of income per capita, the key determinants of the size of firms are trade openness, stock market capitalisation and physical infrastructure. Our simulations suggest that if the gaps with respect to the best Latin American performer were closed in each of these three areas, firm size in the countries of the region would - on average - reach world patterns.

Unit Roots, Cointegration, and Pretesting in Var Models ☆ ☆The views expressed here are the authors and not necessarily those of the Federal Reserve Bank of Atlanta or the Federal Reserve System.

Abstract This article investigates the robustness of impulse response estimators to near unit roots and near cointegration in vector autoregressive (VAR) models. We compare estimators based on VAR specifications determined by pretests for unit roots and cointegration as well as unrestricted VAR specifications in levels. Our main finding is that the impulse response estimators obtained from the levels specification tend to be most robust when the magnitude of the roots is not known. The pretest specification works well only when the restrictions imposed by the model are satisfied. Its performance deteriorates even for small deviations from the exact unit root for one or more model variables. We illustrate the practical relevance of our results through simulation examples and an empirical application.

The Quantitative Effects of Tax Foresight: Not All States Are Equal

This paper explores the effect of federal tax news on state economic activity. We estimate a factor-augmented vector autoregression (FAVAR) model, which allows us to consider the possibility that unobserved factors – such as credit and fiscal conditions – might be relevant for modeling the dynamic response of aggregate and state-level economic activity. We identify tax foresight as a shock to the implicit tax rate, measured by the yield spread between the one-year tax-exempt municipal bond and the one-year taxable Treasury bond. Our results suggest that an increase in the implicit tax rate raises national output over much of the anticipation period. In addition, anticipated tax increases give rise to expansions in state personal income and employment. We find that the variation in the responsiveness of economic activity across states is mostly explained by differences in industrial composition and income distribution, as well as by some demographic characteristics such as median income and education. Finally, using a proxy for exogenous changes in federal tax revenues, we investigate the dynamics of state-level personal income and employment. Our results point to considerable heterogeneity in the response across U.S. states. Moreover, they reveal that the long-run multiplier for an anticipated increase in tax revenues is about a tenth of the short-run multiplier for an unanticipated increase in taxes.
