We utilize full sample size – all the OPEC member countries for the study and panel Autoregressive Distributed Lag (ARDL) model. The Mean Group (MG) and the Pooled Mean Group (PMG) were used to estimate the panel ARDL model, after which we choose the efficient estimator. Brent oil price is used for the main estimation, afterwards, we carry out robustness check using WTI oil price. Our evidence establishes that the estimates are not sensitive to the oil price used. Besides, our findings reveal that oil price and exchange rate are not major determinants of inflation in the short run. Also, we find final demand for goods and services (households’ consumption) to be weak in promoting inflation in both the short and long run. In the long run however, oil price and exchange rate are key factor...
