Economic impacts of climate change on secondary activities: a literature review
No full textThe fast growing literature on economic impacts of climate change is inclined to assessing the impacts on agricultural production and productivity and on human health. The economic impacts of climate change however, go beyond these sectors. In this paper, we attempted to review the scarcely available literature on the economic impacts of the change in the climate of the earth on some selected non-agricultural secondary and tertiary level of economic activities. It is at-tempted to summarize the ways through which the climate change can affect non-agriculture economic activities. The discussion on the literature can be synthesized as showing the impacts on secondary and tertiary level of economic activities are wide and complex and eventually may be larger than on the impacts on agriculture for those middle and high-income countries where the share of agriculture in national GDP is low.This article is available at http://dx.doi.org/10.4236/lce.2012.3200
Is India on a Sustainable Development Path?
Full text linkSustainability requires that the productive base measured in terms of comprehensive wealth of a society should be increasing on per capita basis. Comprehensive wealth includes manufactured, human and natural capital along with knowledge base and institutions. This study offers methodological improvements and provides estimates of the growth rate of per capita comprehensive wealth over the period 1970-2006 for Indian economy. It considers air, water and soil degradation along with energy, minerals and forests depletion. To measure the value and composition of investment in natural capital, it estimates resource depreciation allowances on the basis of Hotelling rent; it adjusts education expenditure for depreciation in human capital; and uses the estimates of TFP that takes into account natural capital in the production of commodities and services. The empirical application suggests that Indian economy is barely sustainable. Growth rate of per capita comprehensive wealth was virtually near zero, it was only 0.15 percent per year for the study period. The growth rate was negative till 1983. Thereafter it became positive; however it was less than one percent in 1980s and 1990s. In recent years the growth rate was about 4 percent. Despite certain limitations, the study underscores the need for vigorous public policies that help in preventing excessive resource depletion and promoting higher genuine investment.Sustainability, development, Comprehensive wealth, Hotelling rent, India
Compensation for environmental services and intergovernmental fiscal transfers : the case of India
No full textThis paper studies mechanisms to compensate local government for the public provision of environmental services using the theory of optimal fiscal transfers in India. Especially, we analyzed the role of intergovernmental fiscal transfers in achieving the environmental goal. Simply assigning the functions at appropriate levels does not ensure optimal provision of environmental services. Optimality in resource allocation could be achieved by combining the assignment system with an appropriate compensation mechanism. Intergovernmental fiscal transfers would be a suitable mechanism for compensating the local governments and help in internalizing the spillover effects of providing environmental public goods.

Resource use efficiency of US electricity generating plants during the SO2 trading regime: A distance function approach.
Full text linkThis paper measures resource use efficiency of electricity generating plants in the United States under the SO2 trading regime. Resource use efficiency is defined as the product of technical efficiency and environmental efficiency, where the latter is the ratio of good output (electricity) to bad output (SO2) with reference to the best practice firm, i.e., one that is producing an optimal mix of good and bad outputs. This concept of environmental efficiency is similar to that of output oriented allocative efficiency. Using output distance functions we compare three methods for the calculation of resource use efficiency, namely, stochastic frontier analysis (SFA), deterministic parametric programming and nonparametric linear programming. This paper reveals the strengths and weaknesses of these methods for estimating efficiency. Both SFA and linear programming approaches can estimate the efficiency scores. For plants in the dataset the overall geometric mean of the three methods for technical efficiency, environmental efficiency and resource use efficiency is 0.737, 0.335 and 0.248, respectively. The rank correlation coefficient between technical efficiency, environmental efficiency and resource use efficiency is 0.213, 0.617 and 0.877, respectively. The regression analyses of performance across plants shows units in phase I of the SO2 trading programme are negatively related to measures of economic and environmental performance. This suggests that the market for SO2 allowances, per se, may not be minimizing compliance cost. We also find that a decrease in SO2 emission rates not only increases environmental efficiency but also leads to an increase in resource use efficiency. This finding concurs with the hypothesis that enhancement in the environmental performance of a firm leads to an increase in its overall efficiency of resource use as well.Technical efficiency ; Environmental efficiency ; Resource-use efficiency ; Distance functions ; SO2 allowance program
Trade-induced technological change : analyzing economic and environmental outcomes
No full textWe analyze how changes in trade openness are related to induced technological innovations that are not only GDP increasing but also pollution saving. Our model includes by-products of carbon dioxide and sulfur dioxide emissions. We estimate a directional distance function for 76 countries over the period 1963-2000 to measure exogenous and trade-induced technological change. On average, we find substantial trade-induced technological progress, and its magnitude is about one third of the overall technological change. The trade-induced technological changes, however, are GDP reducing and pollution increasing. Empirically, we find that increased trade openness correlates to increased pollution
Sulfur dioxide allowances : trading and technological progress
No full textThe US Clean Air Act Amendments introduce an emissions trading system to regulate SO2 emissions. This study finds that changes in SO2 emissions prices are related to innovations induced by these amendments. We find that electricity-generating plants are able to increase electricity output and reduce emissions of SO2 and NOx from 1995 to 2007 due to the introduction of the allowance trading system. However, compared to the approximate 8% per year of exogenous technological progress, the induced effect is relatively small, and the contribution of the induced effect to overall technological progress is about 1-2%. \u
Energy price-induced and exogenous technological change : Assessing the economic and environmental outcomes
No full textIn this paper, we distinguish between factor/output substitution and shifts in the production technology frontier. Our model includes the by-products of carbon dioxide and sulfur dioxide emissions where the function requires the simultaneous expansion of good outputs and reductions in emissions. We estimate a directional output distance function for 80 countries over the period 1971-2000 to measure the exogenous and oil price-induced technological change. On average, we find substantial oil price-induced technological progress at the world level when long-term oil prices are rising, although the growth rate is more volatile in developed countries than in developing countries. The results also show that developed countries experience higher exogenous technological progress in comparison with developing countries, and the gap between the two has increased during the period of our study. \u
Productivity and convergence in India : a state-level analysis
No full textTotal factor productivity plays an important role in the growth of the Indian economy. Using state-level data from 1993 to 2005 that were recently made available, we find widespread regional variation in productivity changes. In the years immediately following economic liberalization, productivity growth improved technical efficiency; however, in subsequent years, productivity growth was propelled by technological progress. We find a tendency toward convergence with regard to productivity growth among states; however, the states that were technically efficient when the economic reforms were instituted remained innovative in later years
Environment and productivities in developed and developing countries : the case of carbon dioxide and sulfur dioxide
No full textWe propose a productivity index for undesirable outputs such as carbon dioxide (CO2) and sulfur dioxide (SO2) emissions and measure it using data from 51 developed and developing countries over the period 1971-2000. About half of the countries exhibit the productivity growth. The changes in the productivity index are linked with their respective per capita income using a semi-parametric model. Our results show technological catch up of low-income countries. However, overall productivities both of SO2 and CO2 show somewhat different results. \u
Measuring Environmental Efficiency of Industry: A Case Study of Thermal Power Generation in India
Full text linkTechnical and environmental efficiency of some coal-fired thermal power plants in India is estimated using a methodology that accounts for firm’s efforts to increase the production of good output and reduce pollution with the given resources and technology. The methodology used is directional output distance function. Estimates of firm-specific shadow prices of pollutants (bad outputs), and elasticity of substitution between good and bad outputs are also obtained. The technical and environmental inefficiency of a representative firm is estimated as 0.10 implying that the thermal power generating industry in Andhra Pradesh state of India could increase production of electricity by 10 per cent while decreasing generation of pollution by 10 percent. This result shows that there are incentives or win-win opportunities for the firms to voluntarily comply with the environmental regulation. It is found that there is a significant variation in marginal cost of pollution abatement or shadow prices of bad outputs across the firms and an increasing marginal cost of pollution abatement with respect to pollution reduction by the firms. The variation in marginal cost of pollution abatement and compliance to regulation across firms could be reduced by having economic instruments like emission tax.environmental and technical efficiency; shadow prices of bad outputs; air pollution
