This paper examines the effect of energy price changes of oil, gas and gasoline on their consumption during 1350-1390 in Iran using vector autoregressive (VAR) model. The results obtained from Impulse Response Functions (IRF) reveal that the consumption of gas and gasoline initially decreases by increasing their prices but would start to rise after a short period. These results suggest that changes in energy prices alone do not have a noticeable effect on the consumption of these products. Therefore, it is suggested that in order to decrease the consumption of energy products in the country we shouldn’t apply pricing policies (increasing the price of oil, gas, and gasoline) as the only policy-making tool. Also, the result obtained by Granger causality shows that there is a unidirectional causality from consumption of energy products to their prices. Moreover, Granger causality test results also show that consumption reduction of oil, gas and gasoline cannot be achieved byonly pricing strategies and in order to reduce the consumption of energy products it is needed to apply non-pricing strategies such as revision of households’ consumption patterns.
