Abstract
Price and income elasticities of gasoline demand show whether the price policy, pursued by the
Iranian government, can decrease the high gasoline consumption sufficiently or not. Since the two
oil price shocks in 1970 and 1973, interest in the study of oil products demand has increased con-
siderably, especially on gasoline. High gasoline consumption is a serious crisis in Iran, posing
economically, politically, and environmentally threats. In this study, the elasticities are estimated
over three intervals, short run, intermediate run, and long run in Iran during 1976-2010, by put-
ting the estimates of Error Correction Model (ECM), static model, and dynamic model in an in-
creasing order, respectively. The short run, intermediate run, and long run price elasticities are
−0.1538, −0.1618, and −0.3612 and the corresponding income elasticities are 0.2273 - 0.3581,
0.4636, and 0.7284, respectively. Not only do these elasticities imply that the gasoline demand is
price and income inelastic but also the adjustment velocity, estimated by ECM, is a low point at
−0.1942. Based on the estimations, the gasoline demand responds to the changes of price and in-
come slightly and slowly. Therefore, policy makers should develop more strategies to reduce
gasoline consumption, for example, substitute goods, public transportation systems, and envi-
ronmental standards settings.
