Understanding the long-run dynamics of OPEC and non-OPEC crude oil prices is important in an era of increased financialization of petroleum markets. Utilizing an ECM within a threshold cointegration and CGARCH errors framework, we provide evidence on the cointegrating relationship and estimate how and to what extent the respective prices adjust to eliminate disequilibrium. Our findings suggest that the adjustment process of OPEC prices to the positive discrepancies is slow which implies that OPEC producers do not prefer moderate oil prices; however, the reverse holds for non-OPEC producers. These results reflect distinct competitive behaviors between OPEC and non-OPEC producers.
