The1.5°C target and coal sector transition: at the limits of societal feasibility

Thomas Spencer, Michel Colombier, Oliver Sartor, and Amit Garg

Climate Policy

National and global mitigation scenarios consistent with 1.5°C require an early phase-out of coal in major coal-dependent countries, compared to standard technical and economic lifetimes. This appears particularly apparent in the light of recent massive investments in coal power capacity, the significant pipeline of coal power capacity coming online, as well as upstream supporting infrastructure. This article analyses the existing and planned capital stock in the coal power sector in the light of scenarios consistent with 1.5°C. The article analyses the political economy and labour aspects of this abrupt and significant transition, in the light of domestic equity and development objectives. Firstly, the article examines employment issues and reviews the existing literature and practice with support schemes for regional and sectoral structural adjustment for the reduction of coal sector activity. Secondly, the paper surveys the domestic political economy of coal sector transition in major coal using countries, namely Australia, South Africa, China and India. A final section provides conclusions and policy recommendations.

HMiner: Efficiently mining high utility itemsets

Srikumar Krishnamoorthy

Expert Systems with Applications

High utility itemset mining problem uses the notion of utilities to discover interesting and actionable patterns. Several data structures and heuristic methods have been proposed in the literature to efficiently mine high utility itemsets. This paper advances the state-of-the-art and presents HMiner, a high utility itemset mining method. HMiner utilizes a few novel ideas and presents a compact utility list and virtual hyperlink data structure for storing itemset information. It also makes use of several pruning strategies for efficiently mining high utility itemsets. The proposed ideas were evaluated on a set of benchmark sparse and dense datasets. The execution time improvements ranged from a modest thirty percent to three orders of magnitude across several benchmark datasets. The memory consumption requirements also showed up to an order of magnitude improvement over the state-of-the-art methods. In general, HMiner was found to work well in the dense regions of both sparse and dense benchmark datasets.

The Impact of self-deception and professional skepticism on perceptions of ethicality

Sobhesh Kumar Agarwalla, Naman Desai, and Arindam Tripathy

Advances in Accounting

This paper examines the impact of two contradictory psychological traits, self-deception (SD) and professional skepticism (PS), on individuals' assessment of ethicality of various earnings management choices. Whereas, SD allows individuals to reduce cognitive dissonance arising from self-serving unethical behavior, PS would force individuals to question such self-serving behavior and, as a result, could make them less likely to act unethically. Our results indicate that SD, PS, and participant type significantly affected the participants' ethicality ratings. Managers exhibiting high (low) SD and low (high) PS view the earnings management techniques that were generally considered to be unethical, as relatively more (less) ethical. However, the SD and PS scores of accountants are not significantly related to their ethicality ratings. This result could be driven by the fact that accountants tend to have greater exposure to information that emphasizes ethics (professional standards and education) and hence psychological traits have a lesser effect on their ethicality ratings.

Child labour and human capital in developing countries - a multi-period stochastic model

Indrajit Thakurta and Errol D'Souza

Economic Modelling

This study investigates the co-determination of child labour and human capital acquisition through a life cycle model. It explores three categories of households with zero, ten and fifteen years' education of household heads who also have differential access to financial markets. Results show that financially excluded, uneducated households prefer assets with negative returns over human capital investments in their offspring, and hence fall into an intergenerational poverty trap. Their educational investments begin only after an income threshold is reached and the same may be funded through transfers or withdrawal of educational subsidies from college educated households without lowering their human capital investments. Educational subsidies and higher access to educational inputs work best for middle educated households who have higher demand for education. For policy analysis, this study quantifies the contributions of income support, financial inclusion, lower uncertainty and subsidised education in reducing the supply of child labour.

The role of cluster presence and quality certification in internationalization and performance of offshore service providers

Rajesh S. Upadhyayula, Karthik Dhandapani, and Amit Karna

Journal of International Management

Offshore Service Providers (OSPs) have been a subject of research for several years now. However, there is little known about what drives the internationalization of OSPs. In this paper, we combine insights from economic geography and institutional view to investigate cluster presence and quality certification as the drivers of OSP internationalization and their performance. We hypothesize the facilitating role these two factors play in driving the performance of internationalized firms. We test our hypotheses using data from Indian software firms between 1992 and 2002. We find a positive effect of certification on OSP internationalization. Although certification contributes negatively to OSP performance, it positively moderates the performance effect of OSP internationalization. Cluster presence was found to drive OSP's overall performance, but has no effect on internationalization. Through our findings, we contribute towards the literature on OSP internationalization.

Energy appliance transformation in commercial buildings in India under alternate policy scenarios

Amit Garg, Jyoti Maheshwari, P.R.Shukla, and Rajan RawalKordrostami

Energy, 140(1), 952-965

The total electricity consumption from commercial sector was about 9% during 2013–14 in India. Load research survey was carried out to study the usage patterns for all types of electric appliances used in commercial establishments at income, appliance and end-use levels in Gujarat state of India – one of the most progressive states. Penetration level of efficient appliances, electricity load curves and Energy Performance Index (EPI) were estimated. The mean EPI was 98 kWh/m2/year (SD = 105.5) for surveyed small commercial establishments (low income) while mean EPI was 181 kWh/m2/year (SD = 68) for surveyed large commercial establishments (Malls). Electricity saving potentials was estimated if electric appliances at these commercial establishments were replaced with efficient appliances. Four alternate scenarios were analyzed using cost of conserved energy (CCE) curves with various efficiency enhancement options – following at least commercial sub-category level median EPIs, following average EU equivalent EPI levels, following average EPI levels of equivalent US commercial establishments, and following the best available technologies (BAT). The average energy savings ranged between 14% and 25% across buildings and scenarios. Energy efficient air-conditioner and LED lights offer the highest energy savings potential among appliances.

Cost-effective architecture of carbon capture and storage (CCS) grid in India

Amit Garg, P.R.Shukla, Shrutika Parihar, Udayan Singh, and Bhushan Kankal

International Journal of Greenhouse Gas Control

Various modeling studies analyzing global 2 °C climate stabilization scenarios have projected penetration of CO2 capture and storage (CCS) technologies in India alongside a sizable penetration of renewable energy technologies. The assessments of geological storage potential over India have shown wide variation across regions. This paper examines the locations of large point sources of CO2 emissions in India and matches it with carbon storage locations to minimize the cost of CCS evolving grid. The concept of weighted Euclidean distance and Integrated Environmental Control Model are used to propose suitable pipeline networks for emissions-intensive clusters to optimize the cost of CO2 avoidance. The computational method estimates proximate storage location for each CO2 emitting source taking into account the total storage potential at each location. CCS requirement in India would vary depending on the global climate stabilization target. We examine two targets for India that correspond to 2 °C and well below 2 °C global mitigation regimes. According to our estimates, India could mitigate around 780 Mt CO2 per year below 60 $/t-CO2 (2005 prices) over 30 years, and another 250 Mt CO2 per year for up to 75 $/t-CO2 prices through CCS under these scenarios respectively.

Urban common service generation, delivery and management: A Conceptual Framework

Arpit Shah and Amit Garg

Ecological Economics

Urban commons are currently not studied holistically under the rationale used by the ecosystem cascade framework. In this paper, we build on the ecosystem cascade framework to present a conceptual model that provides a comprehensive view of urban common resources and allows decision-makers to develop suitable interventions to meet objectives of sustainability and equity. The model looks at the role of and explains the linkages between urban commons' biophysical structures, user population characteristics, power dynamics, use behavior, benefits generated, and management strategies. The model adds to existing literature by focusing on direct benefits and equity and by elaborating on the role of transaction costs and management strategies in governing urban commons. Considering direct benefits allows for a complete picture of overall benefits while making governance decisions, as opposed to considering benefits received only through human effort. Focusing on power asymmetries between stakeholders highlights the inequities created in accessing benefits from urban commons. Elaborating on management strategies provides greater insight into the complexities of managing urban commons and the impacts that governance decisions can have. Finally, including transaction costs highlights the factors that influence costs of managing resources. We illustrate the use of the model with literature from urban India.

Relevance of clean coal technology for India’s energy security: A policy perspective

Amit Garg, Vineet Tiwari, and Saritha Vishwanathan

IOP Conference Series: Earth and Environmental Science

Climate change mitigation regimes are expected to impose constraints on the future use of fossil fuels in order to reduce greenhouse gas (GHG) emissions. In 2015, 41% of total final energy consumption and 64% of power generation in India came from coal. Although almost a sixth of the total coal based thermal power generation is now super critical pulverized coal technology, the average CO2 emissions from the Indian power sector are 0.82 kg-CO2/kWh, mainly driven by coal. India has large domestic coal reserves which give it adequate energy security. There is a need to find options that allow the continued use of coal while considering the need for GHG mitigation. This paper explores options of linking GHG emission mitigation and energy security from 2000 to 2050 using the AIM/Enduse model under Business-as-Usual scenario. Our simulation analysis suggests that advanced clean coal technologies options could provide promising solutions for reducing CO2 emissions by improving energy efficiencies. This paper concludes that integrating climate change security and energy security for India is possible with a large scale deployment of advanced coal combustion technologies in Indian energy systems along with other measures.

Let the people speak: Improving regional adaptation policy by combining adaptive capacity assessments with vulnerability perceptions of farmers in Gujarat, India

Ryan Stock, Trevor Birkenholtz, and Amit Garg

Climate and Development

Farmers throughout the Global South are vulnerable to extreme heat events and shifting precipitation patterns associated with climate change. This is particularly the case in Gujarat, India, which is experiencing fluctuating monsoon rains and seasons. Local institutions there are ill-equipped to assist farmers in adapting to these changes. However, farmers are adapting to climate change, largely through livelihood diversification, in the absence of formal state intervention. Using qualitative methods, we conducted adaptive capacity assessments and assessed vulnerability perceptions in 3 villages, involving 120 farmers from diverse socioeconomic backgrounds. Combining vulnerability perceptions with adaptive capacity assessments, we better observed the mismatch between rural development policy with the potential to aid in adaptation processes that address local needs, identifying why policy fails to increase the adaptive capacity of the agriculturalists most vulnerable to climate impacts. Decentralizing adaptation programmes to community-level institutions can increase the efficacy of climate interventions by emboldening latent institutions, while not widening the socioeconomic gap of a rapidly modernizing India.
