Then in order to study causality relationship among budget deficit, money supply and inflation rate during the period under review was used granger causality test and for this purpose has been used eviews software.
The results of long run normal vector showed money amount and budget deficit have had positive and significant effect on inflation rate during the period under review. Also based on the results of granger causality test there is a direct or indirect relationship among all of the variables in the model.
