Estimation of Poisson mean with under‐reported counts: a double sampling approach

Debjit Sengupta, Tathagata Banerjee, and Surupa Roy

Australian & New Zealand Journal of Statistics

Count data arising in various fields of applications are often under-reported. Ignoring undercount naturally leads to biased estimators and inaccurate confidence intervals. In the presence of undercount, in this paper, we develop likelihood-based methodologies for estimation of mean using validation data. The asymptotic distributions of the competing estimators of the mean are derived. The impact of ignoring undercount on the coverage and length of the confidence intervals is investigated using extensive numerical studies. Finally an analysis of heat mortality data is presented.

Locating resistance to healthcare information technology: A Bourdieusian analysis of doctors' symbolic capital conservation

Mayank Kumar, Jang Bahadur Singh, Rajesh Chandwani, and Agam Gupta

Information Systems Journal

This research examines the socially significant issue of doctors' resistance to healthcare information technology (HIT) from the radical power perspective. It adopts Bourdieu's social practice theory to examine the interaction of HIT with the reproduction of doctors' historically rooted social standing through the doctor-patient-interaction (D-P-I) practice. Findings from our ethnographic enquiry at a large corporate healthcare organisation in India link doctors' historically rooted social standing to the symbolic recognition of their embodied emotional capital existing in tandem with their habitus. The symbolic recognition of emotional capital provided a better valorisation of clinical capital and allowed the accumulation of other forms of capital—institutionalised capital, social capital and economic capital—that formed doctors' capital structure and contributed to their social status. Doctors produced emotional capital by putting their habitus into practice and, in the process, reproduced its symbolic status and their social status linked to it. HIT challenged doctors to put their habitus into practice, thereby creating a perception of threat to emotional capital. Doctors' HIT resistance was a conservation strategy to reproduce their historically rooted higher social status. Findings from this study contribute to the literature on Power and IT resistance.

Prioritising SERVQUAL Dimensions to Improve Trade Show Performance

Dheeraj Sharma, Shivendra K. Pandey, Ashish K. Gupta, and Rajat Sharma

Event Management

The purpose of this article is to examine the suitability of SERVQUAL for trade shows. The objective is to identify the significant SERVQUAL dimensions and their relative importance to increase the purchase intention of visitors to a trade show. The study uses a survey of 400 visitors to a big trade fair. Structural equation modeling was used to determine the relative importance of the dimensions. Results suggest that SERVQUAL is well suited for assessing the service quality of trade shows. The tangibility and assurance are the two most significant factors influencing the purchase intention of trade show visitors. Exhibitors should enhance tangibility in trade shows by methods such as display of product or product prototypes, brochures, and screens. Further, they should increase assurance by displaying medals and awards won, quality certifications achieved, testimonials of past satisfied consumers, and experienced salespeople at the trade show counters. Trade show organizers should attract big brands for the exhibition to enhance assurance. The present study contributes to the ongoing debate on the relevance of SERVQUAL in the trade show context. The study demonstrates that SERVQUAL is a decent measure to study service quality in trade shows even though the majority literature claims otherwise. Further, the present research prioritizes the SERVQUAL dimensions, helping managers to design customer-oriented sales strategies.

Board’s human capital resource and internationalization of emerging market firms: Toward an integrated agency–resource dependence perspective

Anish Purkayastha, Amit Karna, Sunil Sharma, and Dhiman Bhadra

Journal of Business Research

To improve our understanding of the strategic role of the board in emerging market firms (EMFs), we investigate the role of the board’s human capital resource in a firm’s internationalization. Integrating the monitoring role (to reduce agency costs) and the resource provisioning role (to augment strategic resource base) of the board, we propose that the board’s aggregate education and professional experience influence the degree of international expansion of EMFs. Further, the board’s knowledge heterogeneity and skill heterogeneity play a contingent role from a resource orchestration perspective. Based on a dataset of 906 firm-years drawn from 201 Indian firms (2008–2012), we find support for the proposed hypotheses that the board’s aggregate education and professional experience have a U-shaped effect on international expansion, and that this relationship flips to an inverted U-shaped relationship at higher levels of knowledge and skill heterogeneity, respectively, within the board.

Place matters: (Dis)embeddedness and child labourers’ experiences of depersonalized bullying in Indian Bt cottonseed global production networks

Premilla D’Cruz, Ernesto Noronha, Muneeb Ul Lateef Banday, and Saikat Chakraborty

Journal of Business Ethics

Engaging Polanyi’s embeddedness–disembeddedness framework, this study explored the work experiences of Bhil children employed in Indian Bt cottonseed GPNs. The innovative visual technique of drawings followed by interviews was used. Migrant children, working under debt bondage, underwent greater exploitation and perennial and severe depersonalized bullying, indicative of commodification of labour and disembeddedness. In contrast, children working in their home villages were not under debt bondage and underwent less exploitation and occasional and mild depersonalized bullying, indicative of how civil society organizations, along with the state, attempt to re-embed economic activities in the social context. Polanyi’s double movement was evident. ‘Place’ emerged as the pivotal factor determining children’s experiences. A ‘protective alliance’ of community controls and social power, associated with in-group affiliations and cohesive ties, stemming from a common village and tribal identity, aided children working at home for Bhil farmers. ‘Asymmetric intergroup inequality’ due to pronounced social identity and class differences, coupled with locational constraints and developmental disadvantage, made migrant children vulnerable targets. Social embeddedness influences how child workers are treated because it forces employers to be ethical and not engage in bullying. However, by shifting production to children’s home villages, there is an attempt to obscure the difference between child labour and child work. Thus, the seeds of disembeddedness are sown through the very act of re-embeddeding, potentially hampering future interventions.

Chief marketing officers’ discretion and firms’ internationalization: An empirical investigation

V. Kumar, Sourav Bikash Borah, Amalesh Sharma, and Laxminarayana Yashaswy Akella

Journal of International Business Studies

The role of key individuals, such as the chief marketing officer (CMO), in the internationalization process has largely been ignored in the international business literature. Given the importance of the CMO in internationalization and to address this gap in the literature, this study focuses on the role of the CMO – a key individual in organizations who, with adequate levels of discretion, can act as a conduit of knowledge in international markets, facilitating the internationalization of the firm. Drawing on the literature on managerial discretion, internalization theory, and its microfoundations, we argue that the CMO's strategic, operational, and financial discretion, respectively, have positive yet diminishing effects on internationalization. Further, the international experience of the top management team (TMT) and the CMO’s equity compensation moderate these relationships. We contribute to internalization theory and the growing body of literature on the role of the TMT and CMO.

Social mechanisms in crowdsourcing contests: a literature review

Shilpi Jain and Swanand J. Deodhar

Behaviour & Information Technology

Crowdsourcing contests allow organisations to engage with an external workforce. Over the years, the phenomenon has attracted considerable research interest. In the present review, we synthesise the crowdsourcing contest literature by adopting the social mechanism lens. We begin by observing that stakeholders in crowdsourcing contests range from individuals (solvers) to large-scale organisations (seekers). Given that such vastly different entities interact during a crowdsourcing contest, it is expected that their behaviour, too, can have a varying range of predictors, such as individual and organisational factors. However, prior reviews on Crowdsourcing contests and crowdsourcing, in general, haven't explored the phenomenon's multi-layered nature. In addressing this gap, we synthesise 127 scholarly articles and identify underlying social mechanisms that explain key behavioural outcomes of seekers and solvers. Our review makes two specific contributions. First, we determine three distinct tensions that emerge from the key design decisions that might be at odds with the central principle of crowdsourcing contests: broadcast search for solutions from a long-tail of solvers. Second, we provide three recommendations for future research that, we believe, could provide a richer understanding of the seeker and solver behaviour.

Ground truthing the cost of achieving the EAT lancet recommended diets: Evidence from rural India

Soumya Gupta, Vidya Vemireddy, Dhiraj K. Singh, and Prabhu Pingali

Global Food Security

In this paper, we quantify the divergence in the cost of current diets as compared to EAT Lancet recommendations at the subnational-level in India. We use primary data on food prices and household food purchases, and secondary data on food expenditures for a period of 12 months in 2018–19. The cost of the EAT Lancet dietary recommendations for rural India ranges between $3.00- $5.00 per person per day. In contrast, actual dietary intake at present is valued at around $1.00 per person per day. In order to get to the EAT Lancet recommendations individuals will have to spend nearly $1.00 per person per day more on each of meat fish poultry, dairy foods and fruits. The deficit in current diets relative to recommendations is marked by seasonal variations driven by volatility in the underlying food prices. This paper extends the evidence base for the affordability of the EAT Lancet diet to a subnational-level in India, using the most recent data on prices and expenditures, over time. We highlight the need for tracking rural markets at the subnational level, over time for their nutritional quality and ability to provide affordable, nutritious diets to the poor. Crop diversification, investments in rural infrastructure and well-functioning markets can move rural India towards more nutrition sensitive food environments.

How Does Regulation Impact Strategic Repositioning by Firms Across Submarkets? Evidence from the Indian Pharmaceutical Industry

Ajay Bhaskarabhatla, Priyatam Anurag, Chirantan Chatterjee, and Enrico Pennings

Strategy Science

We study coercive institutional pressures as an impetus for firms to reposition across intraindustry boundaries. Integrating the literatures on strategic repositioning and submarkets, we predict that firms respond to regulations limiting the profitability of a submarket by repositioning and shifting demand to proximate, unregulated submarkets within the industry. We expect repositioning to be more pronounced for firms with greater ability to shift demand across submarkets. Evidence from pharmaceutical firms’ responses to partial price regulation in India supports our hypotheses. Repositioning firms increase prices and sales in the unregulated submarket, consistent with a Dorfman–Steiner-type model of endogenous and costly demand shifting toward the unregulated submarket. We contribute to the literature on strategic repositioning and highlight challenges of regulating industries with internal boundaries and insulated niches.

Stochastic modeling of multiline orders in integrated storage‐order picking system

Vishal Bansal and Debjit Roy

Naval Research Logistics (NRL)

Due to demanding service levels in e-commerce order fulfillment, modeling and analysis of integrated storage and order picking processes in warehouses deserve special attention. The upstream storage system can have a significant impact on the performance of the downstream order picking process. With a particular focus on multiline e-commerce orders, we develop an analytical modeling framework for integrated analysis of upstream (shuttle-based storage and retrieval system) and downstream (pick system) networks. To capture the consolidation delays in fulfilling multiline orders, the downstream pick system is modeled with a closed queuing network that includes synchronization nodes. The configuration of the synchronization station is adapted to model the variety of order profiles handled at the pick station. For the downstream closed queuing network, we propose a decomposition-based solution methodology that results in good solution accuracy. The resulting semi-open queuing network (SOQN) of the integrated system is analyzed using the matrix-geometric method (MGM). To improve the accuracy of analytical estimates of the measures, we propose a hybrid simulation/analytical framework, where the performance measures of complex subnetworks are obtained from simulation. We also develop a detailed simulation model of the physical system for validating the analytical and hybrid estimates of the performance measures. The results from experiments indicate that the hybrid simulation/analytical approach reduces the error in the throughput time estimates to 3% from 18% obtained from the analytical model. Then, we investigate the effect of the upstream network configuration (such as the number of storage aisles) and the downstream network configuration (such as the mixed vs. dedicated picking, CONWIP control for orders, order batching) on the order throughput times. Our analysis provides a threshold on the maximum numbers of allowable orders (CONWIP control) and number of aisles beyond which the improvement in average throughput time of the integrated system is marginal. Numerical experiments with high-order arrivals also highlight that mixed picking in the downstream network can result in significant throughput time reduction in comparison to dedicated picking.
