Productivity Trends in India's Energy Intensive Industries

Joyashree Roy, Jayant Sathaye, Alan Sanstad Puran Mongia and Katja Schumacher

Year: 1999
Volume: Volume20
Number: Number 3
DOI: 10.5547/ISSN0195-6574-EJ-Vol20-No3-2
View Abstract

This paper reports on an analysis of productivity growth and input trends in six energy intensive sectors of the Indian economy, using growth accounting and econometric methods. The econometric work estimates rates and factor price biases of technological change using a translog production model with an explicit relationship defined for technological change. Estimates of ownprice responses indicate that raising energy prices would be an effective carbon abatement policy for India. At the same time, our results suggest that, as with previous findings on the U.S. economy, such policies in India could have negative long run effects on productivity in these sectors. Inter-input substitution possibilities are relatively weak, so that such policies might have negative short and medium term effects on sectoral growth. Our study provides information relevant for the analysis of costs and benefits of carbon abatement policies applied to India and thus contributes to the emerging body of modeling and analysis of global climate policy.

The Role of Energy in Productivity Growth: A Controversial Issue?

Luis R. Murillo-Zamorano

Year: 2005
Volume: Volume 26
Number: Number 2
DOI: 10.5547/ISSN0195-6574-EJ-Vol26-No2-4
View Abstract

The main objective of this paper is to clarify the controversial role of energy in productivity growth. This is done by reconciling conventional approaches to the measurement of aggregated productivity growth with the microeconomic foundations provided by the energy economics and frontier productivity measurement literature. The use of Malmquist productivity indices allows us to broaden previous research by decomposing productivity growth into technological progress and technical efficiency change as well as analysing the relationship between energy and both sources of productivity change. By doing so, our findings are that energy indeed matters and that the consideration of technical efficiency contributes to a better understanding of both the temporal evolution and cross-country variability of aggregated productivity growth.

Environmental and Energy Efficiency of EU Electricity Industry: An Almost Spatial Two Stages DEA Approach

Simona Bigerna, Maria Chiara D’Errico, and Paolo Polinori

Year: 2019
Volume: Volume 40
Number: The New Era of Energy Transition
DOI: 10.5547/01956574.40.1.sbig
View Abstract

This study analyzes the relationship between the energy efficiency and the stringency of environmental and market regulation in the electricity sectors has been analyzed. Using 19 European Union countries (2006-2014), we decomposed the environmental policy stringency index, the OECD regulatory indicators and the total factor productivity growth to highlight the complexity of the relations between electricity sector and regulatory policies. In the first stage we compute the three main components of total factor productivity. These three efficiency measures are used in the second stage to assess the impact of the regulatory policies on the total factor productivity also controlling for spatial effect. Results suggest that market and environmental regulations have not unidirectional impacts on the three components of total factor productivity. Pure and scale efficiency index are negatively affected by sectorial regulation that positively affect the shift of technological frontier. Environmental policy negatively affects the shift of the efficient frontier, but has a positive effect on the scale efficiency.

Impact of Energy Market Distortions on the Productivity of Energy Enterprises in China

Weijian Du, Mengjie Li, Ke Li, and Jiang Lin

Year: 2021
Volume: Volume 42
Number: Number 4
DOI: 10.5547/01956574.42.4.wdu
View Abstract

China aims to enhance its total factor productivity (TFP) to achieve sustainable development. However, the looming energy market reform and its accompanying energy distortions prevent the realization of this ambitious goal. This study first establishes a theoretical model to reveal the inhibitory effects of energy market distortions on the TFP of energy enterprises, and we examine this issue using the micro-data of Chinese energy enterprises. The empirical results indicate that relative distortions among energy enterprises and overall distortions in different regions significantly inhibit the promotion of energy enterprises TFP, but the marginal inhibitory effects are diminishing. Energy market distortions also inhibit enterprises' entry and accelerate enterprises' exit from the energy market. Thus, eliminating inappropriate interventions in micro-energy enterprises, establishing a unified national energy market, and improving the competitive environment of energy companies are of great theoretical and policy importance.

Green Growth, Carbon Intensity Regulation, and Green Total Factor Productivity in China

Xiaobo Shen and Boqiang Lin

Year: 2022
Volume: Volume 43
Number: Number 6
DOI: 10.5547/01956574.43.6.xshe
View Abstract

Based on input-oriented Malmquist productivity index and parametric decomposition approach, this paper measures China's green total factor productivity (TFP) index and its growth sources using a panel dataset of 30 provinces of China mainland from 1997 to 2014, and assesses the effect of CO2 intensity regulation on the green TFP growth in China. The results show that the green TFP has been growing at a yearly averaged rate of –1.51% during this period. The results also indicate that the policy of CO2 intensity regulation does not generate significant effect on the green total factor productivity of China's provinces when using the two stage least squares (2SLS) estimator to control for the potential endogeneity biases. On the other hand, there exists significant heterogeneity in the effect of the CO2 intensity regulation on the green TFP of China's provinces. Specifically, the CO2 intensity regulation promotes the green development performance of provinces in the eastern area, while it does not generate obvious impacts on the green TFP of provinces in both central and western areas.
