Abstract

This study attempts to extract the new keynesian phillips curve for OPEC and G7 countries and compare the factors influencing inflation between the two groups. The study covers the period of 1995-2017 and the econometrics method used to estimate the model is the Bayesian Panelvar. The results showed that the effect of expected prices on inflation for the OPEC and G7 countries in the first period is positive. but, this effect disappears for OPEC countries after a while. But in the G7 countries, not only does it not disappear, but for some countries it becomes more(Japan) and for some it becomes negative(France).The expected price effect has a more lasting effect on inflation in G7 countries.Also, the output gap has a similar effect on inflation in all OPEC countries, and in the first periods it has a negative effect on inflation, and after a while this effect disappears completely. However, this variable has a positive effect on inflation in almost all countries in the G7 countries in the first period. But, gradually, the effect of this variable on inflation in some countries is increasing(Japan and Germany) and some negative(France, Canada, USA and Italy).The effect of the previous period's inflation on the inflation of OPEC and G7 countries is quite similar. Also, the results showed that the citizens of the G7 countries pay more attention to the expected price in forecasting inflation than the OPEC group, and the people of the OPEC member countries consider the inflation of the previous period more.
