A Practical Note on Predictive Analytics Usage in Marketing Applications

Arindam Banerjee and Tanushri Banerjee

Most Predictive Analytics discussions focus on methods that can be used for better quality prediction in a particular context. Realizing that the possibility of perfect prediction is a near impossibility, practitioners looking to support their futuristic initiatives wonder, what is a suitable model for their use.
In other words, if all prediction models are imperfect (have leakage) how much of this imperfection can be tolerated and yet better decisions can be taken with model output. This paper is an attempt to provide a simplified approach to this practical problem of evaluating model performance taking account of the decision context.
Two scenarios are discussed; a) a classification problem often used for profiling customers into segments and, b) a volume forecasting problem. In both cases, the leakage is defined (misclassification or uncertainty band) and their impact (adverse) on the subsequent decision is identified. Contextual dimensions that have an impact on the quality of the decision and the scope to alleviate the problem are also discussed.

Factors Influencing Outcome Expectations and
Self-Efficacy in Driving Internet Use in Rural India

Rekha Jain

Past studies of individual Internet adoption and usage have been mostly empirical and in developed countries or in urban settings of developing countries. These have largely examined socio-economic factors such as age, earnings, education, in driving adoption and use. Several of the past studies were done at a time when the Internet was a novelty and was primarily considered as a source of information for enhancing knowledge. Over time, with developments in social media and ecommerce, Internet is considered an effective medium for social networking, enabling knowledge creation and exchange and enhancing economic benefits. Using theory of social capital and social cognition helps us to understand the drivers of Internet use from the perspective of outcome expectations and self-efficacy along the social, economic and knowledge dimensions. The primary research question is: What factors drive outcome expectations and self-efficacy in Internet use?

Our study is based on a survey in two rural areas (Ranchi, Jharkhand, India) and (Guna, Madhaya Pradesh, India). We used theory to develop a survey instrument on Internet users for understanding the drivers of Internet use based on outcome expectations and self-efficacy. We used data from the Principal Component Analysis (PCA) done previously, to identify the latent constructs as measures of outcome expectations and self-efficacy (Jain, 2016). Using ANOVA, the current study identified the differential across Age, Occupation, Digital Literacy, Earning, and Education on dimensions uncovered by PCA and related the findings to the rural context in a developing country.

The PCA revealed three dimensions that were labelled as 'Empowerment', 'Enhanced Scope of Work' and 'Transaction Efficacy'. There are statistically significant differences across those who are at different levels of Digital Literacy and Earnings and for 'Transactional Efficacy', in the two groups identified by type of Occupation as 'Business' and 'Others'. Along the other two dimensions of 'Empowerment' and 'Enhanced Scope of Work', there is no statistically significant difference across these two categories of Occupation. Further, there are no statistically significant differences across different categories of Age and Education.

Our results indicate that while a basic level of education may determine whether a user adopts Internet, once the user starts using the Internet with a goal orientation in terms of outcome expectations and self-efficacy, 'Education' level does not matter. A similar logic applies to 'Age'.

Since digitally literate users tend to have positive outcome expectations from Internet use, they may benefit far more than those who are not Digitally Literate. Therefore, public policy must not only focus on increasing Internet availability specifically in rural areas, there must be programs for increasing digital literacy as well. Without such support programs, Internet use outcomes would exclude those who are not as digitally literate. Since Internet is increasingly becoming the vehicle for economic growth, such exclusions could slow inclusive growth.

Those with higher incomes had possibly higher levels of negative disconfirmations with Internet use than those with lower incomes. A similar logic applies for the 'Transactional Efficacy' component in the 'Occupation' category. The study identifies the possible drivers for the disconfirmations.

Measuring the Perceived Impact of Internet on
Individuals in Rural India

Rekha Jain

Internet has greatly influenced the way individuals socialize, create and exploit economic opportunities and knowledge resources. However, previous studies on assessment of impact have largely been empirical and limited to examining the factors influencing adoption and usage of Internet only from a social and economic perspective. These have not considered the role of knowledge enhancement and exchange. In addition, few studies measure impact in an integrated manner and are based on theory. Consequently, the constituent dimensions of impact, their inter-relationships and their intensity have not been articulated.

To develop a construct for measuring impact of Internet use, we have used two theoretical and complementary domains: Social Capital and Social Cognitive Theory. Since Internet is considered a network for social exchanges, a study of Perceived Impact of Internet would need to take into account the aspect of social capital consequent to adoption and usage of Internet. On another dimension, usage of Internet could lead to increase in economic capital due to enhanced opportunities for business or profession. Internet is also a source of knowledge that could enhance economic or social benefits by creating opportunities for businesses or professional growth. Thus what constitutes impact is a complex construct broadly manifested along social, economic and knowledge dimensions. Further, most studies of Internet impact have not examined the role of outcome expectations and self-efficacy, two important constructs from theory of Social Cognition, in driving Internet use.

Our study is driven by the need to develop a theoretical model for measuring impact by identifying the underlying dimensions that constitute impact and creating a construct for measuring the same. Lack of studies of impact of Internet in developing countries, especially in rural areas was another driver.

We have used a survey based instrument administered to Internet users covering two of the poorer districts in Jharkhand, and Madhya Pradesh, India. Principal Component Analysis was used to identify the latent perceptual dimensions that constitute impact. Subsequently, we used linear regression to posit the strengths of each identified dimension in contributing to Perceived Impact.

The model highlights the importance of using Internet for overcoming vulnerabilities in a rural context, negative disconfirmation with respect to having Enhanced Scope of Work through Internet use and social context of knowledge creation and cognition. The negative disconfirmation could be attributed to possibly low self-efficacy or not completely fulfilled outcome expectations from available services. Lack of content in local language, poor presence of local websites, low presence of associates and partners on the Internet, and inadequate quality of Internet connectivity contribute to this.

Dedicated High Speed Rail Network in India: Issues in Development

G. Raghuram and Prashanth D. Udayakumar

India and Japan have signed a memorandum of understanding to set up a high speed rail (HSR) network costing INR 976.36 billion, between Mumbai and Ahmedabad. As of now, the top speed in India is 150 kmph, and that too for a few special trains in limited segments of their run. The Ministry of Railways first proposed HSR in 2007-08 and have conducted pre-feasibility studies on various routes in the country.
While documenting the progress of proposed HSR routes for India, the paper also draws lessons from international HSR experience in Europe and Asia. For the development of HSR network in India, there are a variety of issues. This paper examines issues with regards to route fixation, choice of technology partner and need for standards, location of stations, choice of grade level, choice of gauge and interoperability of trains beyond core networks, and pricing, revenues and funding.

Open Innovation at different levels for Higher Climate Risk Resilience

Anamika Dey, Anil K. Gupta, and Gurdeep Singh

As climate variability is increasing, creating knowledge networks is becoming more and more important for bringing in, or leveraging the embedded resilience in the communities through cross-pollination of ideas, resources and insitutional linkages. Communities have developed knowledge systems around climate mediated environmental changes since time immemorial. Some social groups have capacity to cope with stress better. They have homeostatic advantage due to either accumulated surplus (Burton, 2001) or access to institutions, technology and social networks (Adger, 2003) . However, these knowledge systems often remain limited as isolated islands or small local networks resulting into asymmetries of knowledge at inter or intra-community level. Intermediary organizations become important to bridge the gap that exist among communities within the informal sector and also between the formal and informal sector. There organizations and platforms like The Honey Bee Network have been able to facilitate both horizontal exchanges, people to people learning and sharing; and vertical exchanges, connecting the informal actors with the formal system. The framework in this paper helps in studying the difference in different components of Open Innovation System through their degree of openness of sharing, self-governance and self-regulation. We explore the different activities and institutions of The HB Network to study the degree of openness and how they contribute to make the system which has now existed for 26 years, more sustainable. We draw lessons for other institutions, organizations, communities who strive towards an autopoietic system i.e. self-designed, self-organized and self-governed system with a feedback system from within and outside, making the whole innovation and knowledge ecosystem sustainable towards the changing and fluctuating environment.

Empathetic climate resilient frugal innovations for sustainable communities

Anamika Dey and Anil K. Gupta

Dealing with risk and uncertainty has contributed to the evolution of local knowledge, institutions and culture among farming, pastoral and artisanal communities at grassroots level. The traditional institutions, practices and ways of finding contemporary innovative solutions to emerging problems still remain relevant even if some of the indicators or specific practices may have lost their relevance (Leonard, Sonia, et al , 2013, Corinne Valdivia, D. Green and G. Raygorodetsky, 2010 , Coleen Vogel et. Al., 2007 ). Institutional adaptation plays no less important a role through collective action (Daivi Rodima-Taylor, Mette F. Olwig, Netra Chhetri, 2012, also see www.sristi.org/cpri). The resilience requires not just actor based study but also the role of entire socio-ecological system (Gupta, 1984, Donald R. Nelson, W. Neil Adger,and Katrina Brown, 2007) This paper focuses more on technological adaptation and innovation (Gupta, 1992,1995, 1989, 2006, 2012). The grassroots innovations emerging in a materially constrained environment invariably leverage knowledge, ingenuity and local resources in a very frugal and empathetic manner.
In part one, creative and innovative coping strategies of knowledge rich-economically poor people are summarized. Part Two deals with the contours of emergent inclusive innovative ecosystem in India over the last 25 years of Honey Bee Network. Part three lists emerging inclusive models of innovations having bearing on creativity at the grassroots level. Trends in innovation literature, particularly from an open innovation perspective are reviewed in part four followed by a summary of key points at the end.

Human Resource Issues in Maternal and Neonatal Health in India

Sunil Kumar Maheshwari and Dileep Mavalankar

One in seven women die from complications related to pregnancy or delivery in some of the African countries, compared to one in many thousands in Europe and North America. More than 95 per cent of maternal deaths occur in developing countries. In the developing countries complications of pregnancy mainly due to inadequate Emergency Obstetric Care (EmOC) is the leading cause of death among women of reproductive age. They account for 18 per cent of the burden of health disease in reproductive age group-more than any other single health problem (World Bank ,1993). At least 40 per cent of pregnant women experience some type of complication during their pregnancies. Most maternal complications and death occur either during or shortly after delivery and are difficult to predict. Nearly 15 per cent of complications are life-threatening that require immediate EmOC. However, many of them do not receive adequate EmOC. Hence, "Safe Motherhood" will remain a dream in the absence of adequate EmOC.
As in any services, health services are highly dependent of the human resources - its availability, quality, commitment and performance. EmOC services are even more dependent on highly skilled human resources as they need complex procedures as Caesarean Section (CS) and other emergency procedures. Thus ensuring access to quality maternal services including EmOC is a major challenge in Human Resources Management (HRM). In this paper we present an outline of key issues in HRM which specifically relate to MH and EmOC, based on our experience in India and review of literature.

An Examination of One Dimension Marginal Distributions: Selling and Non-selling Activities of a Salesperson

Dheeraj Sharma and Mir Ghulam Haider Talpur

Past researchers have endeavored to examine and ascertain the time that salespeople spend engaged in core and non-core activities. In this study, the time spent by a salesperson on non-core activities is called vacation time. This study examines the number of times a salesperson engages in vacation and the time taken by the number of vacations by controlling the number of customers. The one dimensional marginal probability generating (transform), density and cumulative distribution functions of the random variables , and are obtained by controlling the variability of two random variables simultaneously.

Executive Stock Options: Will It Work as a Good Governance Mechanism in all Scenarios?

Preet Deep Singh and Chitra Singla

Agency theory proposes different mechanisms to mitigate agency costs in the firms. An executive stock options (ESoPs) is one of such mechanism, which is given to the CEO of the firm to align CEO's goals with that of the owners. In this paper, we contend that ESoPs will not work as a good governance or mitigation mechanism in all types of firms. ESoPs can be an effective mitigation mechanism for a firm with dispersed ownership but it might not be the case for a firm with majority or block shareholding. We extend this argument for ESoPs given to board members as well. We present a framework to understand when it makes sense for a firm to incentivise top management with ESoPs.

Open Access Temptations: Buyer Beware

Vineet Virmani

Backlash against "megapublishers" which began in mathematics a decade ago has led to an exponential growth in open access journals. Their increasing numbers and popularity notwithstanding, there is evidence that not all open access journals are legitimate. The nature of the "gold open access" business model and increasing prevalence of "publish or perish" culture in academia has given rise to a dark under-belly in the world of scientific publishing which feeds off academics' professional needs. Many such "predatory" publishers and journals not only seem to originate out of India but also seem to have been patronized by academics in the country. This article is a cautionary note to early-career academics and administrators in India to be wary of this "wild west" of the internet and exercise discretion when considering/evaluating open-access journals for scholarly contributions.
