Abstract

In this paper, we model the relationship between oil price and inflation for selected OPEC and EU countries using monthly data from 2000 to 2014. We employ both the Linear (Symmetric) ARDL by Pesaran et al. (2001) and Nonlinear (Asymmetric) ARDL by Shin et al. (2014) and we also account for structural breaks using the Bai and Perron (2003) test that allows for multiple structural changes in regression models. Six findings are discernible from our analyses. First, the relationship between oil price and inflation tends to change over short periods. Secondly, the oil price-inflation nexus is stronger in oil exporting countries than oil importing countries. Thirdly, oil price asymmetries seem to matter more when dealing with oil exporting nations. Fourthly, it may be necessary to pre-test for structural breaks when modelling the relationship between oil price and inflation regardless of the category being analyzed. Fifth, while asymmetric effect for the oil exporting (OPEC) is not sensitive to structural breaks, the effect seems to diminish for oil-importing (EU) countries in the presence of breaks. Sixth, while the results are largely insensitive to the nature of data frequency, the behaviour of asymmetry suggests otherwise.
