The real-time Price Elasticity of electricity
Energy Economics, 2007Co-Authors: Mark G. LijesenAbstract:The real-time Price Elasticity of electricity contains important information on the demand response of consumers to the volatility of peak Prices. Despite the importance, empirical estimates of the real-time Elasticity are hardly available. This paper provides a quantification of the real-time relationship between total peak demand and spot market Prices. We find a low value for the real-time Price Elasticity, which may partly be explained from the fact that not all users observe the spot market Price. If we correct for this phenomenon, we find the Elasticity to be fairly low for consumers currently active in the spot market. If this conclusion applies to all users, this would imply a limited scope for government intervention in supply security issues. © 2006 Elsevier B.V. All rights reserved.

The Price Elasticity of Natural Gas Demand in China: A Meta-Regression Analysis
Energies, 2018Co-Authors: Jian Chai, Huiting Shi, Xiaoyang Zhou, Shouyang WangAbstract:Since natural gas has become a new star in China’s energy mix, a reliable estimation of the Price Elasticity of natural gas demand is crucial if we are to understand how energy Price changes affect natural gas consumption. In this paper, we conduct a Meta-regression analysis to quantitatively synthesize empirical estimates of the Price Elasticity of natural gas demand reported in previous studies, provide true underlying values, and explain the heterogeneity of the aforementioned estimates. The Fixed-effects model and ordinary least squares (OLS) are applied to estimate the regression models. As a result, this paper reports a mean Elasticity of −1.521 and 0.410 for the short- and long-run own-Price Elasticity, separately; −0.762 and 0.008 for the short- and long-run cross-Price Elasticity-coal to natural gas, respectively; 2.122 and 1.884 for the short- and long-run cross-Price Elasticity-electricity to natural gas, separately; and 2.267 and 1.275 for the short- and long-run cross-Price Elasticity-oil to natural gas, respectively. Our results suggest that natural gas consumption increases with the decrease of its own and coal Prices in the short term and rise of electricity and oil Prices. It also shows that almost all heterogeneity can be explained by the type of data, sample period, models of analysis, geographical region, and type of consumer.

Price Elasticity estimates for tobacco products in india
Health Policy and Planning, 2008Co-Authors: Rijo M JohnAbstract:The tax base of tobacco in India is heavily dependent on about 14% of tobacco users, who smoke cigarettes. Non-cigarette tobacco products accounting for 85% of the tobacco consumption contributes only 15% of the total tobacco taxes. Though taxation is an important tool to regulate consumption of tobacco, there have been no estimates of Price elasticities for different tobacco products in India to date, which can guide tax policy on tobacco. This paper, for the first time in India, examines the Price Elasticity of demand for bidis, cigarettes and leaf tobacco at the national level using a representative cross-section of households. This study found that own-Price Elasticity estimates of different tobacco products in India ranged between -0.4 to -0.9, with bidis (an indigenous hand-rolled smoked tobacco preparation in India) and leaf tobacco having elasticities close to unity. Cigarettes were the least Price elastic of all. With some assumptions, it is shown that the tax on bidis can be increased to Rs. 100 per 1000 sticks compared with the current Rs. 14 and the tax on an average cigarette can be increased to Rs. 3.5 per stick without any fear of losing revenue. The paper argues that the current system of taxing cigarettes in India based on the presence of filters and the length of cigarettes has no justification on health grounds, and should be abolished, if reducing tobacco consumption and the consequent disease burden is one of the objectives of tobacco taxation policy. It also argues that attempts to regulate tobacco use without effecting significant tax increases on bidis may not produce desired results.

Price Elasticity of demand of non cigarette tobacco products a systematic review and meta analysis
Tobacco Control, 2018Co-Authors: Mohammed Jawad, John Tayu Lee, Stanton A Glantz, Christopher MillettAbstract:Objective To systematically review the Price Elasticity of demand of non-cigarette tobacco products. Data sources Medline, Embase, EconLit and the Web of Science without language or time restrictions. Study selection Two reviewers screened title and abstracts, then full texts, independently and in duplicate. We based eligibility criteria on study design (interventional or observational), population (individuals or communities without geographic restrictions), intervention (Price change) and outcome (change in demand). Data extraction We abstracted data on study features, outcome measures, statistical approach, and single best own- and cross-Price Elasticity estimates with respect to cigarettes. We conducted a random effects meta-analysis for estimates of similar product, outcome and country income level. For other studies we reported median elasticities by product and country income level. Data synthesis We analysed 36 studies from 15 countries yielding 125 Elasticity estimates. A 10% Price increase would reduce demand by: 8.3% for cigars (95% CI 2.9 to 13.8), 6.4% for roll your owns (95% CI 4.3 to 8.4), 5.7% for bidis (95% CI 4.3 to 7.1) and 2.1% for smokeless tobacco (95% CI −0.6 to 4.8). Median Price elasticities for all ten products were also negative. Results from few studies that examined cross-Price Elasticity suggested a positive substitution effect between cigarette and non-cigarette tobacco products. Conclusions There is sufficient evidence in support of the effectiveness of Price increases to reduce consumption of non-cigarette tobacco products as it is for cigarettes. Positive substitutability between cigarette and non-cigarette tobacco products suggest that tax and Price increases need to be simultaneous and comparable across all tobacco products.
