nowadays, transportation sector consumes about 27 percent of the whole energy in iran. therefore, after domestic and business sectors which consume about 40 percent of the whole energy, transportation is placed in the second rank. however, the financial value of transportation is of the highest importance. moreover, having 55percent of gasoline product consumption transportation has been also r...

Gasoline taxes can correct externalities associated with automobile use, reduce dependency on foreign oil, and raise government revenue. Our understanding of the optimal gasoline tax and the efficacy of existing taxes is largely based on empirical analysis of consumer responses to gasoline price changes. In this paper, we directly examine how gasoline taxes affect consumer behavior as distinct ...

according to the global fuel crisis, it seems necessary to use alternative fuel instead of gasoline. since the natural gas is cheaper, have higher frequency than gasoline and less pollution, it is a suitable fuel. many efforts have been done in order to replace gasoline with natural gas. one of the methods is to inject natural gas and gasoline fuel simultaneously and to use the benefits of both...

Although most people are thought to receive their highest acute exposures to gasoline while refueling, relatively little is actually known about personal, nonoccupational exposures to gasoline during refueling activities. This study was designed to measure exposures associated with the use of an oxygenated fuel under cold conditions in Fairbanks, Alaska. We compared concentrations of gasoline c...

gasoline is the most important energy product in the passenger transportation sector in iran. gasoline demand survey has a high priority in iran because of its ever-increasing consumption. the most important challenges for this purpose are uncertainties resulting from structural failure of economy, changing of policies and lack of accurate data. this research aims to specify the variables expla...

the effects of unleaded gasoline and unleaded gasoline–ethanol blends on engine performance and pollutant emissions were investigated experimentally in a single cylinder, four-stroke spark-ignition engine with variable engine speeds (2600–3500 rpm). four different blends on a volume basis were applied. these are e0 (0% ethanol + 100% unleaded gasoline), e3 (3% ethanol + 97% unleaded gasoline), ...

We examine how gasoline price volatility impacts consumers’ price elasticity of demand for gasoline. Results show that volatility in prices decreases consumer demand for gasoline in the intermediate run. We also find that consumers appear to be less elastic in response to changes in gasoline price when gasoline price volatility is medium or high, compared to when it is low. Moreover, we find th...

Gasoline “divorcement” regulations restrict the integration of gasoline refiners and retailers. Theoretically, vertical integration can harm competition, making it possible that divorcement policies could increase welfare; alternatively, these policies may reduce welfare by sacrificing efficiencies. This paper attempts to differentiate between these possibilities by estimating a reduced form eq...

Using the most recently available data, this paper estimates the price and income elasticities of gasoline demand in the United States from a semiparametric smooth coefficient model. The econometric approach provides more flexibility by allowing functional coefficients to accommodate heterogeneity in gasoline demand. Instrumental variables are used to correct for the potential endogeneity of th...
