Consumer Rights in the New Economy: Amending the Consumer Protection Act, 1986

Akhileshwar Pathak

Liberalisation and globalisation of the India economy, inaugurated in 1990, ushered in a qualitatively different economy. In these decades, there has been expansion of goods and services; diversification in the means of reaching the consumer; proliferation of trade practices; coming in of e-commerce; vigorous sales promotion; and aggressive advertising. The persona of a consumer has undergone a transformation. The legislative regime for protection of consumer needs reform. The government has suggested changes in the Consumer Protection Act, 1986. Taking this as the context, the article reviews the proposed amendments and identifies further areas for amendment. The article has identified four overarching aspects of consumer rights for review, unfair terms in contracts; unfair trade practices; commerce through online platforms; and definition of consumer.

Dynamic Pricing of Electricity: A Survey of Related Research

Goutam Dutta and Krishnendranath Mitra

In this paper, we survey 82 papers related to revenue management and dynamic pricing of electricity and lists future research avenues in this field. Dynamic pricing has the potential to modify electric load profiles by charging different prices at different demand levels and hence can act as an effective demand side management tool. There are different forms of dynamic prices that can be offered to different markets and customers. Forecasting of demand, and demand price relationship play an important role in determining prices and helps in scheduling load in dynamic pricing environments. Consumers' willingness-to-pay for electricity services is also necessary in setting price limits. Elasticity of demand is an indication of the demand response to changing prices. Market segmentation can enhance the effects of such pricing schemes. Appropriate scheduling of electrical load enhances the consumer response to dynamic tariffs.

A Note on Estimating Variance of Finite Population Distribution Function

Sumanta Adhya, Tathagata Banerjee, and Gouranga Chattopadhyay

Estimating finite population distribution function is an important problem to the survey samplers since it summarizes almost all the relevant information of interest about the finite population. Moreover due to its nonlinearity estimation of variance of estimators of distribution function remains an active area of research since Chambers et al., 1992. Both analytic and resampling-based variance estimators are developed earlier. Here we poropse a bootstrap hybrid variance estimator of model-based semi-patametric estimator of finite population distribution function estimator. We prove its consistency and also show that its numerical performances are superior to analytical estimator.

How Costly is the Deliberate Disinflation in India?
Estimating the Sacrifice Ratio

Ravindra H. Dholakia and Kadiyala Sri Virinchi

Methods followed in earlier studies for estimating the sacrifice ratio or the real cost of deliberate disinflation have focused only on aggregate supply side ignoring aggregate demand. The present study considers the adjustment path obtained as a locus of short run equilibria to arrive at a theoretically acceptable sacrifice ratio. The study uses quarterly data from the period between 1996-97Q1--2013-14Q4 in India and employs both the regression as well as the direct methods to estimate the ratio. The results have revealed a sacrifice ratio ranging from 1.7 to 3.8 depending on the method and the measure of inflation used. Such a magnitude of the real cost of disinflation in India, also relevant in the long run, clearly contradict the dominant view among policymakers that the trade-off, if any, is negligible. Deliberate disinflation policy needs to consider the real cost of sacrificing output and employment particularly when its magnitude is substantial.

Specialist Services in the Indian Rural Public Health System for Maternal and Child Healthcare – A Study of Four States

Shreekant Iyengar and Ravindra H. Dholakia

The present study attempts to examine the role of specialist services in rural public health system of India in the areas of maternal and child healthcare. The study uses primary data collected through a survey of doctors and paramedical staff working at public health facilities regarding availability and quality of the specialist services in gynaecology, paediatrics and anaesthesia. The study discusses in detail the aspects of infrastructure, manpower and operational challenges faced in effective provisioning of specialist services through the rural health facilities of four largest states-Bihar, Madhya Pradesh (MP), Rajasthan and Uttar Pradesh (UP). The findings of the survey reveal significant dearth of specialist doctors with their concentration at the district level. Moreover, there are severe misallocations of the specialist doctors and, lack of manpower support, equipment and basic infrastructure within the public health system causing serious challenges in effective provisioning of specialist services for maternal and child healthcare. Lastly, the efforts made by the government for providing additional manpower support for these services are also not giving desired results.

Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Ordinance 2014: A Process Perspective

G. Raghuram and Simy Sunny

This paper captures the policy processes leading to the Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement (RFCTLARR) Ordinance, 2014. It maps the role and the influence of the three primary stakeholders - Government, industry and landowners - at various stages of the evolution of the land acquisition law in India. Land acquisition has remained a controversial issue in India resulting in conflicts between social, economic and political structures. The RFCTLARR Act 2013 was an attempt by the earlier Government to provide a fair deal to the landowners who had suffered due to the weak framework of the Land Acquisition Act, 1894. The Government also had one year until December 31, 2014 to decide on whether 13 Special Acts which had land acquisition privileges should come under this Act or be exempted. However, the Act soon faced resistance from the industry due to the impact of clauses like social impact assessment, rehabilitation and resettlement, and consent requirements on projects done in public interest. After constant pressure from the industry and consultations from the State Governments, the new Government finally brought in amendments to the 2013 Act. Given the one year deadline and the washout of the winter session of Parliament, it brought in the amendment through an ordinance.

ROC Curve Analysis for Randomly Selected Patients

Tathagata Bandyopadhyay, Sumanta Adhya, and Apratim Guha

Receiver operating characteristic (ROC) curves and the area under the curve (AUC) are widely used in medical studies to examine the effectiveness of markers in diagnosing diseases. In most of the existing literature for ROC curve analysis it is assumed that the healthy and the diseased populations are independent of each other, which may lead to bias in the studies. In this paper we consider the disease status as a binary random variable. Assuming the disease status is determined by a latent variable and the marker and the latent variable have a bivariate normal distribution, we derive the properties of the ROC curve and the AUC. We also look at the problem of choosing optimum combination of markers when multiple markers are present. Limiting distributions are obtained and confidence intervals are discussed as well. A small simulation study is performed which confirms the superiority of our methods over the general practice of considering the two populations to be independent.

Economic Globalization: Boon or Bane for African Health?

Vishalkumar Jani and Ravindra H. Dholakia

The effect of globalization, especially economic liberalization, on socioeconomic development has long been debated in development economics. There is a view that globalization is not beneficial to the underdeveloped and developing world. Africa is always put forward as an example. So it is important to see what is really the impact of international integration and increasing trade on countries of Africa. Evidence for this is very limited and inconclusive. The present study attempts to decipher how health status of African countries is impacted by the economic liberalization. It aims to bridge the gap between the two strands of literature: (i) impact of economic liberalization on growth, and (ii) effect of economic growth on health status.
The findings show a positive effect of globalization on the health status of African countries with those having lower income and underdeveloped status in initial period benefiting more.

Dynamics of Land Use Competition in India:
Perceptions and Realities

Vijay Paul Sharma

Diversion of agricultural land to non-agricultural uses is an issue of public debate in every agrarian economy experiencing rapid urbanization and industrial development. However, the issue has become more complex and politicised in India due to widely varied perceptions about the extent of diversion of agricultural land and the causes and socio-economic consequences of loss of agricultural land. It is generally perceived that large-scale conversion of agricultural land to non-agricultural uses has occurred and the issue of acquisition of large tracts of fertile land by corporates and displacement of farmers, agricultural workers, and other rural communities has become a major political rather than socio-economic issue. We try to determine whether the perceptions are consistent with empirical evidence on land use competition and identify main drivers that contribute to loss of agricultural land.
The evidence shows that agricultural land conversion has become a serious issue in the country but the extent and intensity varies across different states. Between triennium ending (TE) 1991-92 and TE2011-12, net sown area in the country declined by about 1.8 million ha but it increased in some states, e.g. about 20 lakh ha in Rajasthan and 9.5 lakh ha in Gujarat. In contrast, Odisha lost over 17 lakh ha net sown area, Bihar (including Jharkhand) 12.4 lakh ha, Maharashtra (7.6 lakh ha), Tamil Nadu (7.1 lakh ha), Karnataka (3.1 lakh ha), Andhra Pradesh (2.7 lakh ha) and West Bengal (2.6 lakh ha). Contrary to general perception, Gujarat is the only state which has been able to add about 3 lakh ha to its total agricultural land during last two decades. Area under non-agricultural uses increased from 21.3 million ha in TE1991-92 to 26.3 million ha in TE2011-12 and almost all states witnessed an increase in area under non-agricultural uses. The empirical results revealed that urbanization, road infrastructure expansion and industrial development were the most important factors affecting agricultural land. Therefore, proper planning and management of land resources and appropriate policy framework are required to check conversion of agricultural land. Managing urbanization process and industrial as well as infrastructure expansion in a desired way that protects productive agricultural land and uses barren and unculturable wastelands (about 17.2 million ha) is very critical to country's prosperity and sustainability. Hence, restriction on conversion of agricultural land for non-agricultural uses (mainly for industrial estates) and proper planning and implementation of land use policies are needed. The recent and current trends in agriculture and non-agriculture land use should not be a cause for either panic or complacency. However, strategic planning that avoids land use conflict by identifying areas, mainly barren and unculturable wastelands, for non-agricultural activities such as urban and industrial expansion and protecting productive farm lands is necessary to address land use conflicts and co-existence of agriculture and other non-agricultural activities. The problem of small and fragmented farms underlines the need for revisiting tenancy laws so as to increase the effective farm size.

Predicted Increases in Heat related Mortality under Climate Change in Urban India

Hem H. Dholakia, Vimal Mishra, and Amit Garg

Mapping mortality impacts of the projected climate in urban areas of developing countries will play a crucial role in instituting planned adaptation measures to protect public health. We provide a comprehensive assessment of mortality in 52 urban areas (population >1 million) that are located in diverse climactic regimes in India. To understand implications of the climate warming on heat wave mortality in the urban India, we used downscaled and bias corrected temperature projections from the Coupled Model Inter-comparison Project Phase 5 (CMIP5) models. Using the observed data for the period of 2005-2012, we developed temperature-mortality relationships using Poisson regression models for the selected urban areas in India. These relationships were applied to future temperature projections from the 23 CMIP5 models for the summer and winter seasons for the Representative Concentration Pathway 4.5 and 8.5 scenarios. Here we show that urban areas in India are projected to witness two-fold or more increases (p <0.05) in heat related mortality (i.e. summer season) under the projected future climate. Mortality is projected to increase 71and 140% in the late 21st century under the RCP 4.5 and 8.5 scenarios, respectively. Moreover, we find that increases in the heat related mortality will overshadow declines in the cold related mortality (winter season). Moreover, urban areas of Delhi, Ahmedabad, Bangalore, Mumbai and Kolkata are projected to experience the highest absolute increases in the heat related mortality in 2080s under the RCP 8.5 scenario. Our findings underscore the need for Indian policy makers to anticipate, plan and respond to the challenge of climate change.
