The transport systems are dependent on the fossil fuels especially liquid fuels and these fuels are depleting at much faster rate than production. The consumption of fossil fuels is very unstable and directly affects the economy of our country as we are importing it from other nations so this factor has urged us to find other alternatives to prolong the usage of petroleum. Thus, by using bio-fu...
In recent years, calls for carbon taxes as a policy tool to combat global warming have kept a discussion of the price and income elasticities of gasoline demand alive. To date, gasoline demand elasticity estimates are almost exclusively based on aggregate data that are subject to aggregation problems and make distributional concerns impossible to address. By using Ž . household-level data from ...
A partially linear model is often estimated in a two-stage procedure, which involves estimating the nonlinear component conditional on initially estimated linear coefficients. We propose a sampling procedure that aims to simultaneously estimate the linear coefficients and bandwidths involved in the Nadaraya-Watson estimator of the nonlinear component. The performance of this sampling procedure ...
Our objective in this study was to assess the effect of using two kinds of lead-free gasoline [including 92-lead-free gasoline (92-LFG) and 95-lead-free gasoline (95-LFG), rated according to their octane levels] to replace the use of premium leaded gasoline (PLG) on the emissions of polycyclic aromatic hydrocarbons (PAHs) and their corresponding benzo[a]pyrene equivalent (BaP(eq)) amounts from ...
The present paper explains the dynamics of substitution tensions between fossil energy carriers for gas consumption in the transportation sector of Iran in the horizon of 2025 using seasonal space model and Kalman filter approach for the years 2006-2019 in the form of quarterly data. Based on the results; Price elasticity and revenue elasticity of gasoline and gas oil are -0.20, -0.15, 0.27 and...
Estimating Oil Products Demand by State-space Model and Relevant Guidelines for Price Liberalization
The purpose of this paper is to estimate oil products demand by the state-space model, taking into account the implications for price liberalization using the Kalman filter technique in the framework of a time-varying pattern. For this purpose, we use the data of the Energy Balance Sheet and the National Iranian Oil Refining and Distribution Company during the period of 1994-2017. Our model res...
Despite the presence of 90% of double-fuel taxis (gasoline + CNG) in the urban taxi fleet, fuel consumption choices are more dependent on pricing policies and factors such as gasoline subsidies and quotas, and with the slightest change in fuel rates and quotas, use natural gas fuel. . Impact and challenge fuel management in the public transport fleet. The main purpose of this is to identify way...
Continuing rapid growth in U.S. gasoline consumption threatens to exacerbate environmental and congestion problems. We use flexible semiparametric and nonparametric methods to guide analysis of household gasoline consumption in 1988 and 1991. The number of licensed drivers has a strong effect on consumption, and including this variable cuts the estimated income elasticity in half. Slower projec...
The evaluation of the impact of an increase in gasoline tax on demand relies crucially on the estimate of the price elasticity. This paper presents an extended application of the Partially Linear Additive Model (PLAM) to the analysis of gasoline demand using a panel of US households, focusing mainly on the estimation of the price elasticity. Methodologically, we propose a root-n consistent esti...
