To prevent further increases in energy consumption, the government of Iran commenced energy subsidy reform in 2010. This paper investigates the fuel conservation effects of the reform in Iran using a homothetic translog cost function that provides estimates of the own- and cross-price elasticities of fuel demands. The percentage reduction in fuel demands is estimated using the likely effect of ...

Existing diesel engines are under stringent emission regulation particularly of smoke and particulate matter in their exhaust. Compressed Natural Gas and Diesel dual fuel operation is regarded as one of the best ways to control emissions from diesel engines and simultaneously saving petroleum based diesel fuel. Dual fuel engine is a conventional diesel engine which burn either gaseous fuel or d...

Keywords: Jet aircraft Fuel price Operating cost Leontief technology Translog a b s t r a c t Investigation of the airline response to a fuel price increase is in effect an investigation of the role of variable interactions in aircraft cost models. We examine the impact of fuel price on aircraft costs and airline operational strategies by developing two classes of operating cost models for jet ...

This paper analyzes short-run interfuel substitution between fossil fuels in West European power generation. The problem is studied within a restricted translog cost model, which is estimated by pooling time-series data across eight countries in West Europe. The empirical results indicate that interfuel substitution in existing power plants is substantial, especially that between oil and gas. T...

This paper investigates interfuel substitution in the UK manufacturing sector. Econometric models of inter-fuel substitution are applied to energy inputs aggregated by their energy use, and separately for thermal heating processes, where interfuel substitution is technologically feasible. Compared to aggregate data, estimated own-price fuel demand elasticities for all fuels and cross-price elas...

a r t i c l e i n f o The electric power industry is restructuring as regulations move from states to regional and national levels. Estimates of regional fuel and input substitution are essential for practitioners and policy makers. This paper estimates substitution under static and dynamic scenarios, examining changes in technology and total factor productivity from 2001 to 2008. Two-stage est...

While the wealth effect from a capital influx would induce households to buy more dirty fuel, they might simultaneously reduce their purchases depending on the degree of substitutability with clean fuels and other consumption. This substitution effect will not necessarily dominate the wealth effect, unless dirty fuels are an inferior good. However, a capital increase could also cause labor to b...

Since 1973, the U.S. economy has shifted from a ability in the fishing industry have been conducted. The position characterized by abundant and low-cost enlack of studies on the substitution possibilities between ergy to one of rising energy prices and fragile energy energy and nonenergy inputs leaves a void in the apsupplies, periodically threatened by an unstable forpropriate information upon...
