The Demand for Natural Gas: A Survey of Price and Income Elasticities

Mohammed A. Al-Sahlawi

Abstract:
My purpose has been to survey and review price and income elas-ticities of the demand for natural gas. The surveyed studies are classified by demand type, where the functional forms, estimation techniques, data types, estimated periods and concerned countries or regions are indicated. Studies have demonstrated that there is variation in price and income elasticity estimates. These discrepancies are due to differing estimated periods, various data sources, structural changes, geographical differentials, and the distinction between different demand types. In the short run, it appears that industrial demand and residential-commercial demand are inelastic with respect to price and income. Industrial demand is more responsive to income than residential-comercial demand in the short run as well as in the long run. This might be caused by the differences between natural gas end uses.



Forecasting the Demand for Electricity in Saudi Arabia

Mohammed A. Al-Sahlawi

Year: 1990
Volume: Volume 11
Number: Number 1
DOI: 10.5547/ISSN0195-6574-EJ-Vol11-No1-10
View Abstract

Abstract:
Electric power in Saudi Arabia is an essential tool for modern economic development. Thus, forecasting electricity demand is vital for planning and investment purposes. In estimating future electricity demand, it is important to assure high responsibility that there will be no supply shortages. Nonparametric analysis techniques like bootstrap, the jackknife, and cross-validation are becoming increasingly popular in the estimation of probability density function of a variable or its function (see Efron (1979) and Efron and Gong (1983)).
