Macroeconomic Structure and Oil Price Shocks at the Industrial Level

Pages 173-189 | Received 11 Mar 2009, Accepted 20 Apr 2010, Published online: 09 Mar 2011
 

Abstract

This paper analyses the role of the macroeconomic structure in the response of industrial output to an oil price shock in six OECD countries. The modelling of the macroeconomic structure is important in examining the effect of an oil price shock on the industry-level output, since the analysis of the transmission mechanisms helps us to better understand the response of industrial output to such a shock. Thus, cross-country differences found in the responses of industrial output to oil price shocks within the European Monetary Union can be partially explained by differences in the transmission mechanisms of such shocks.

Notes

1See Hamilton (Citation1983, Citation1996, Citation2003), Gisser and Goodwin Citation(1986), Mork Citation(1989), and Hooker Citation(1996), among others, for the US; and Burbidge and Harrison Citation(1984), Mork et al. Citation(1994), Jiménez-Rodríguez and Sánchez (Citation2005, Citation2009), and Kilian Citation(2008) for countries different from the US.

2We find other authors who analysed the US industry-level effects of oil price shocks on other research topics (creation and destruction of manufacturing job, Davis and Haltiwager, Citation2001; inventory-sales, Herrera, Citation2007; and stock returns, Kilian and Park, Citation2009).

3Bohi Citation(1989) compared the industrial impact of oil prices in Japan, Germany, the UK, and the US, although his comparisons were informal.

4Total industrial production is used as a proxy of economic activity. It is worth stressing that this variable and GDP are highly correlated and that the latter is only available at quarterly frequency.

5Real effective exchange rate is defined such that an increase means a real appreciation of the currency considered. An appreciation of the real exchange rate is expected to hurt the country's external competitiveness.

6The use of non-linear transformations of oil price to analyse the impact of oil price shocks on aggregate output has been theoretically justified by the inter-sectoral adjustments with which they are involved (see Jiménez-Rodríguez & Sánchez, Citation2005, and references therein). Thus, we do not apply such transformations in our study, given that our main goal is to analyse the impact at the industrial level, and their use may give rise to biased results.

7The macroeconomic block includes, apart from total industrial production and real oil prices, other variables to capture some of the most important transmission channels through which oil prices may affect real economic activity indirectly, in part by inducing changes in economic policies. These channels include the effects of oil prices on inflation and exchange rates, which then induce changes in real economic activity. Our macroeconomic block also incorporates a monetary sector that can react to inflationary pressures.

8In this paper we do not perform an explicit analysis of the long-run behaviour of the economy. By doing the analysis in levels we allow for implicit cointegrating relationships in the data, and still have consistent estimates of the parameters. For further discussion in this issue, see, for example, Sims et al. Citation(1990), Hamilton Citation(1994), and Ramaswamy and Sløk Citation(1998).

9Davis and Haltiwanger (2001) also did the same assumption in their study about the effects of oil price changes and other shocks on the creation and destruction of US manufacturing jobs.

10The likelihood ratio tests (based on the so-called block-exogeneity test) indicate that the block-recursive restrictions (i.e. R 12(L)=0) cannot be rejected for most industries and most countries. Even in the cases of rejection, the estimate of the variance-covariance matrix of the macroblock, Ω11, is not significantly altered by the presence of the specific industrial output. Thus, we estimate under the restriction that macroeconomic variables are not affected by the specific industrial output.

11It is worth noting that the non-recursive structure (contrary to the recursive one) allows us here to consider the contemporaneous interactions between the interest rate and the exchange rate, and the non-reaction of the interest rate contemporaneously to changes in output and inflation (see Sims & Zha, Citation1998), as well as the contemporaneous interactions between the interest rate and money stock (see Kim & Roubini, Citation2000).

12Our baseline results are robust to other identifying schemes. An Appendix with these results is available from the author upon request.

13Notice that A 21 and Ω21 contain the same numbers of elements, and so we do not impose restrictions. The same situation happens with A 22 and Ω22.

14The OECD database ‘Indicators for Industry and Services’ is available from 1975:1 to 1998:12 based on International Standardized Industrial Classification (ISIC) Revision 2 and from 1990:1 to 2001:9 based on ISIC Revision 3. We use data from ISIC Revision 2 and do not extend up to 2001:9 given that OECD advises that the two classification systems (ISIC Revision 2 and ISIC Revision 3) are not fully compatible and, thus, comparisons have to be made with caution.

15As in Jiménez-Rodríguez Citation(2008), we start the Spanish sample in 1980:1, given that the Spanish policy of subsidizing oil prices (implemented up to the end of the 1970s) may have distorted the effects of oil price shocks on the Spanish industries.

16Notice that the growth tendency of real oil prices from 2002 onwards differs from previous oil price shocks, which were mainly caused by sizeable disruptions to the supply of oil. The factors driving the oil price increases over the last few years were basically caused by demand factors. See Kilian Citation(2009) for further discussion.

17The finding that higher oil prices adversely affect the UK manufacturing activity is in concordance with the result reported by Jiménez-Rodríguez and Sánchez Citation(2005) for overall economic activity.

18Jiménez-Rodríguez Citation(2008) considers a recursively identified bivariate VAR model with real oil prices in domestic currency and specific industrial output as variables (entering into the bivariate model in that order), and this model is estimated by the maximum likelihood estimation approach.

19We have verified that the same conclusion can be obtained by analysing whether the responses resulting from the bivariate model are within the 90% confidence intervals calculated around the responses of our multivariate model. These results are available from the authors upon request.

20It is worth stressing that the macroeconomic block does not lead to more homogeneous output responses across industries in those countries for which cross-industry heterogeneity is found using the bivariate model (France, Germany, and Spain).

21The only exception to this is Italy, where the monetary aggregate only lessens after one year.

22Looking at the forecast error variance decomposition, we observe that the main two sources of volatility (apart from oil prices) for most industries are interest rates and real effective exchange rates in all countries.

23Authors such as Bohi Citation(1989) and Bernanke et al. Citation(1997) argued that overall economic downturns observed in the US after oil price shocks are caused by a combination of direct impacts of the shocks themselves and the monetary responses to them.

24An Appendix with all these results is available from the author upon request.
