The geography of medical travel in India: Differences across states, and the urban-rural divide

Sandip Chakrabarti and Aruna Divya T

Applied Geography

There is a large body of literature exploring spatial disparity in access to healthcare services, and the resultant geographic inequality in the demand for medical travel. We are, however, unaware of any such study conducted in India in the past. The transportation implications of inequitable healthcare access, therefore, remains unknown to Indian planners and policymakers. We use a unique dataset, the 2014–15 Domestic Tourism Expenditure survey conducted by the National Sample Survey Office, Ministry of Statistics and Programme Implementation, Government of India, to address this critical gap in the literature. We use trip-making information of 42,547 persons (13,525 urban and 29,022 rural residents) belonging to 28 Indian states in order to analyze the variation in individuals' medical trip destination choice, on average, across states. We analyze overnight trips (i.e., trips involving at least one night stay away from home) made for medical purposes only. Specifically, we isolate and compare the independent influence of state of residence (i.e., the state-effect) on residents' choice of within-district and out-of-state medical care location, after controlling for various personal and household factors that also govern choice. Additionally, we select a sub-sample of individuals who made out-of-state medical trips, and analyze state-level differences in the likelihood of long or >1500 km (vs. short or ≤1500 km) distance medical travel. We analyze urban and rural residents separately, and estimate a pooled model to explore intra-state urban-rural differences in medical trip destination choice. Our analyses reveal significant variation in urban and rural residents' destination choice for medical trips across India's states. We also find within-state urban-rural differences in destination choice to vary significantly across states. Our analysis provides new information on the geography of medical travel in India, underscoring the need for further research on the causes and consequences of the geographic disparity in healthcare access, and targeted action to improve healthcare access equitably across states. We expect our paper to stimulate further research to guide national and state health and transportation policies in India.

Do tweets create value? A multi-period analysis of Twitter use and content of tweets for manufacturing firms

Adrija Majumdar and Indranil Bose

International Journal of Production Economics

In this research we enquire if adoption of Twitter by manufacturing firms creates any value for the firm. We conduct two studies to examine the relationship between Twitter related activities of manufacturing firms and the market reaction towards these firms. We collect a novel multi-period dataset and analyse the overall impact of adoption of Twitter on Tobin's Q by employing a propensity score matching and difference-in-difference research design. Our findings suggest that adoption of Twitter increases the value of the firm post adoption. We also conduct additional robustness check such as use of Industry Week data as a proxy of firm value and find our results to be consistent. We adopt a text mining-based approach and examine the communication environment of the manufacturing firms. We use the Latent Dirichlet Allocation (LDA) algorithm for short texts and identify six broad topics among tweets posted by firms. Our panel regression based analysis suggests that there is positive association between divulging product related information and Tobin's Q. Our research showcases the strong impact of use of Twitter and contributes to the nascent literature on firm generated content. It is likely to encourage managers of manufacturing firms to start actively using Twitter for sharing product related information on social media.

Bilevel optimization based on iterative approximation of multiple mappings

Ankur Sinha, Zhichao Lu, Kalyanmoy Deb, and Pekka Malo

Journal of Heuristics

A large number of application problems involve two levels of optimization, where one optimization task is nested inside the other. These problems are known as bilevel optimization problems and have been studied by both classical optimization community and evolutionary optimization community. Most of the solution procedures proposed until now are either computationally very expensive or applicable to only small classes of bilevel optimization problems adhering to mathematically simplifying assumptions. In this paper, we propose an evolutionary optimization method that tries to reduce the computational expense by iteratively approximating two important mappings in bilevel optimization; namely, the lower level rational reaction mapping and the lower level optimal value function mapping. The algorithm has been tested on a large number of test problems and comparisons have been performed with other algorithms. The results show the performance gain to be quite significant. To the best knowledge of the authors, a combined theory-based and population-based solution procedure utilizing mappings has not been suggested yet for bilevel problems.

Supporting and sustaining state-initiated women's empowerment: Learning from a national programme in India

Ankur Sarin and Vijaya Sherry Chand

Journal of International Development

State-led women's empowerment initiatives are usually indifferent to the tensions between the processes of transformation they initiate at the grassroots and the intermediary support structures they create to sustain empowerment. Drawing on the experiences of Mahila Samakhya, a programme initiated by the Indian state in the late 1980s, we argue that the failure of the state to acknowledge the struggles of the intermediary layers to reconcile the social purpose of transformation with the economic logic underpinning organizational survival only leads to reinforcing a new form of ‘neo-liberal compatible’ governance. © 2019 John Wiley & Sons, Ltd.

Downstream electric utility restructuring and upstream generation efficiency: Productivity dynamics of Indian coal and gas-based electricity generators

Anish Sugathan Anish Sugathan, Deepak Malghan, S Chandrashekar, and Deepak K. Sinha

Energy

This paper investigates the producer-level temporal dynamics of total factor productivity and operational performance changes in coal- and gas-based generators during the 2000–20013 period of major structural reforms in the downstream utilities in India. The total factor productivity is estimated using a recently developed improvement in the Stochastic Frontier panel method that controls for time-invariant unobserved heterogeneity, and the productivity change is decomposed into components of changes in technology frontier, efficiency, scale and allocation. A unique dataset of station-level data for coal and gas plants, that represents about two-thirds of all power generation in India during this period, is constructed for the analysis. The study shows that while there is improvement in the coal generator productivity at the mean rate of 0.20% per year that converges towards a point of higher efficiency for most plants, the gas generators show a trend of stagnant efficiency and declining total factor productivity at the mean rate of −0.80% per year. Unbundling and multi-dimensional utility reform indices are significantly associated with improvement in thermal efficiency and capacity utilization for coal generators. In contrast, utility reforms shows no significant positive influence on gas generators, instead a decline in capacity utilization is observed following unbundling.

Reverse innovation: a conceptual framework

Suresh Malodia, Shaphali Gupta, and Anand Kumar Jaiswal

Journal of the Academy of Marketing Science

Reverse innovation (RI) has emerged as a new growth strategy for MNCs to innovate in emerging markets and then to further exploit the profit potential of such innovations by subsequently introducing them not only in other similar markets but also in developed markets, thereby delivering MNCs a sustainable growth globally. In this study, we propose an overarching conceptual framework to describe factors that contribute to the feasibility of RIs. Using grounded theory with a triangulation approach, we define RI as a multidimensional construct, identify the antecedents of RI, discuss the outcomes, and propose a set of moderating variables contributing to the success of RIs. We also present a set of research propositions with their relative effects on the relationships proposed in the conceptual framework. Additionally, we provide future research directions and discuss theoretical contributions along with managerial implications to realize the strategic goals of RI.

Innovations in public administration in India

Dipti Gupta, Ashok Kumar Pandey, and Amit Garg

Economic & Political Weekly

Innovations in public service could be a core driver for ensuring that public administration becomes competitive, efficient, cost-effective and accountable to the citizenry. This state of innovation in India is analysed through the Prime Minister’s Awards for Excellence in Public Administration for the period 2005–06 to 2016–17. The analysis shows that most of the innovations are management innovations, followed by technological innovations. They indicate some degree of direction in good governance and replicability. There is also need for some scouting mechanism for public administration innovations and for providing a replicable yet flexible template to promote them across the country.

Achieving sustainable development in India along low carbon pathways: Macroeconomic assessment

Dipti Gupta, Frederic Ghersi, Saritha S Vishwanathan, and Amit Garg

World Development

Achieving fast and inclusive economic growth concurrently with greenhouse gases (GHG) emission control could have wide-ranging implications for the Indian economy, predominantly fuelled by fossil energies. India faces high income inequality with the bottom 50% of its population owning only 2% of total national wealth. Other developmental challenges include 304 million people living in poverty, 269 million without access to electricity, 92 million without access to safe drinking water, and around 2 million homeless. Despite such challenges, India has committed to reduce the GHG emission intensity of its GDP 33–35% below its 2005 level by 2030, including via turning 40% of its power-generation capacity away from fossil sources. To explore the macroeconomic consequences of achieving development along low-carbon pathways, we use a hybrid modelling architecture that combines the strengths of the AIM/Enduse bottom-up model of Indian energy systems and the IMACLIM top-down economy-wide model of India. This hybrid architecture stands upon an original dataset that reconciles national accounting, energy balance and energy price statistics. With this tool, we demonstrate that low-carbon scenarios can accommodate yearly economic growth of 5.8% from 2013 to 2050 i.e. perform close to if not slightly higher than our business-as-usual scenario, despite high investment costs. This result partly stems from improvement of the Indian trade balance via substantial reduction of large fossil fuel imports. Additionally, it is the consequence of significant shifts of sectoral activity and household consumption towards low-carbon products and services of higher value-added. These transitions would require policies to reconcile the conflicting interests of entrenched businesses in retreating sectors like coal and oil, and the emerging low-carbon sectors and technologies such as renewables, smart grids, electric vehicles, modern biomass energy, solar cooking, carbon capture and storage, etc.

Pain without gain?: Impact of school rationalisation in India

Ambrish Dongre and Vibhu Tewary

International Journal of Educational Development

Alarmed by declining enrolment in government schools and potentially adverse academic, administrative and fiscal consequences associated with it, policy makers in India have initiated experimenting with closure of government schools with low enrolments (‘small’ schools), an exercise commonly referred to as ‘school rationalisation’. However, the impact of this policy on access to schooling and learning remains empirically unexplored. Utilising ASER 2014 data, this paper asks three key questions: (a) what are the characteristics of villages in which ‘small’ schools are located?, (b) what options would students have if ‘small schools’ were to be closed, and finally (c) what are the differences in characteristics of ‘small’ and non-‘small’ schools? Results indicate that the villages which have ‘small’ schools are more disadvantaged in terms of essential public services such as all-weather roads leading to village, availability of government health facilities or banks and post offices. Additionally, these villages are less likely to have an alternative to the ‘small’ school, either government or private. Results also show that ‘small schools’ are much more likely to have multi-grade teaching. They are less likely to have basic infrastructural facilities. Interestingly, learning levels are unlikely to be different in ‘small’ schools than non- ‘small’ schools even after controlling for child, household and village attributes. Thus, the analysis suggests that school rationalisation can potentially have severe consequences on children’s access to schools without any meaningful impact on learning levels in a ‘business as usual’ scenario.

Understanding parental mediation of violent television commercials

Akshaya Vijayalakshmi, Russell Laczniak, and Deanne Brocato

Journal of Consumer Marketing

Purpose

This study aims to uncover in-depth examples of how emergent media affects parents’ views and socialization efforts. The study examines these views and efforts in the context of violent commercials.

Design/methodology/approach

The authors collected data for this paper using two studies. In Study 1, they collected data from the internet. Comments related to “violent ads” or “violent commercials” were collated and analyzed. For Study 2, they conducted in-depth interviews with mothers on their views on parental mediation and impact of media on their children.

Findings

The internet data helped develop a parental definition of violent ads and identify that parents lie on a continuum regarding their concerns about violent commercials. Further in-depth questioning of parents on the above finding led to the identification of four clusters of parents. “Media managers” attempt to control and restrict their child’s media environment while educating their child about the effects of violent commercials. “Enablers” spend abundant time co-viewing primetime TV while engaging their child in conversations on violence, but not on violent ads. To maintain harmony in the household, “Harmonizers” merely restrict viewing of violent commercials without educating their child about its effects. Finally, “Agent evaluators” are likely to co-view violent commercials, without discussing them with their child.

Research limitations/implications

First, several of the parental segments (media managers, enablers and harmonizers) tend to note some concerns with violence in advertising. Importantly, this concern for violence appears to be limited to gore and use of physical weapon. Second, while parents do not have homogenous views on violent ads, those who are concerned also have differing roots of concern. This influences their mediation efforts. Third, socialization is bi-directional at times.

Practical implications

Many parents do not approve are the use of physical violence, use of weapons and depiction of blood/gore even in ads for movies or videogames. Advertisers might be wise to avoid such content in ads directed to children. Second, if media and marketing managers could plan to sponsor TV shows (vs placing violent ads) that offer ad-free program time, parents might respond positively. Third, as socialization is bi-directional, advertisers could consider using ad scenarios where parents and children engage with the pros and cons of a certain product or content, thus enabling parent-child conversations to make an informed decision.

Social implications

Many parents notice violence in ads; policymakers could consider developing ratings for ads that consider the amount and type of violence while rating an ad. Second, a focus on increasing parental awareness on the harms of constantly exposing children to violent commercials might change the views of some parents who currently believe that a few or no violent commercials are being aired during children’s programs. Finally, parents envisage a greater role for media in their lives, and policymakers will have to suggest ways to effectively integrate media content in one’s lives rather than just suggest bans or restrictions.

Originality/value

The contributions of this paper include viewers’ (vs researchers’) definition of violent commercials, showcasing that parents are likely to manage media using new media options such as Netflix, and some parents are likely to co-create rules with their children.
