Paper Title: Dynamic choice in a complex world

Abstract

We consider an environment in which a Decision Maker (DM) finds it sufficiently complex to even describe the state space, let alone guess the parameters of the underlying data generating process. He is therefore unable to use the standard Bayesian methods. Instead, at each moment in time, the DM constructs a preference relation on the set of available actions based on their past performance. We postulate a set of axioms on this family of preference relations indexed by histories (of rewards). Two key conditions, a typical dium; Exchangeability axiom and another labeled Consistency, that constraints the DM not to update her preferences after certain events (loosely based the “the principle of insufficient reason”), characterize thumb rules for ranking actions that are akin to the familiar fictitious play in game theory. Moreover, if in fact the stochastic process that generates the rewards is exchangeable, a DM that obeys our axioms (almost surely) cannot be distinguished in the long run from one that is fully cognizant of the environment and satisfies the expected utility hypothesis. The main result requires proving a representation result on multisets which may be of independent interest.

Paper Title: An Interproduct Competition Model Incorporating Branding Hierarchy and Product Similarities Using Store-Level Data

Abstract

We develop and implement a Bayesian semiparametric model of demand under interproduct competition that enables us to assess the respective contributions of brand-SKU (stock keeping unit) hierarchy and interproduct similarity to explaining and predicting demand. To incorporate brand-SKU hierarchy effects, we use Bayesian hierarchical clustering inherent in a nested Dirichlet process to simultaneously partition brands, and SKUs conditional on brands, into groups of “similarity clusters.” We examine cluster memberships and postprocess the Markov chain Monte Carlo output to infer cluster properties by accounting for parameter uncertainty. Our proposed approach lends to a spatial competition interpretation in latent attribute space and helps uncover the extent to which competition across SKUs in the latent attribute space is local or global. In a related vein, we discuss the implications of well-defined groups of similar SKUs as subcategory or submarket boundaries in latent attribute space. We empirically test our model using aggregate beer category sales data from a midsize U.S. retail chain. We find that branding hierarchy effects dominate those from product similarity. We find that the model partitions the 15 brands in the data into 4 brand clusters and the 96 SKUs into 25 SKU clusters conditional on brand cluster membership. In estimating a set of models of spatial interproduct competition, we find that SKU competition is more local than global in that only subsets of products compete within groups of comparable products. Finally, we discuss the substantive implications of our results.

Paper Title: Bayesian estimation of long-term health consequences for obese and normal-weight elderly people.

Abstract

Obesity is a rapidly growing public health problem even among the elderly. Understanding the disabling consequences of obesity in the elderly will help us to design better effective intervention management guidelines for the elderly obese. To examine the long-term health consequences of the obese elderly, we present a joint model consisting of two bivariate ordered responses observed at successive time points. The bivariate ordered response model corresponds to the subject’s self-reporting health status outcomes including self-rated health and functional status. Although the joint model that we propose is generally suited for use in health and disease research, where the ordered value responses are observed at successive time points, we further extend it by addressing some of the challenges by incorporating the semiparametric features in the ordinal logistic model, by modelling the underlying latent states of health that are associated with self-rated health, by jointly modelling the bivariate ordinal out-comes to mitigate the variability of the single response and by accounting for the non-ignorable missing data due to different reasons through a multinomial logit model. The motivating data were obtained from the Second Longitudinal Study of Aging, which are longitudinal survey data from 1994–2000 providing various useful information on the health status of elderly people. Parameter estimation of our joint model was performed in a Bayesian framework via Markov chain Monte Carlo methods. Analytical results demonstrate the difference in longitudinal pat- terns of the health outcomes between the two weight groups, validating our hypothesis that different management strategies for the obese elderly should be employed.

Top 3 reasons why MOOCs should play a role in the classroom

The past decade has seen MOOC emerge as a buzzword – much has been discussed about the hype around it, its efficacy, revenue model, academic rigour and so on. But, is MOOC an emerging technology? Hasn’t distance learning been around for a while? How is a MOOC different from erstwhile distance learning? Is it just old wine in a new bottle? What we need to understand is that MOOC is different; it is a pedagogically powerful tool and is structured to mimic the classroom learning as much as possible. In fact, MOOCs can be seen as a means to improve faculty effectiveness and to augment the learning experience in the classroom.

  1. Reskill and Re-invent Yourself as a 21st Century Teacher: As faculty, why should we talk about MOOCs and why are they relevant? Globalization and technology like MOOCs have removed geographical borders between academicians and students – a student from Chandigarh University, India can learn from a European school; an IIMB teacher can teach learners in Africa and so on. The way forward for an academician to stay relevant is to orchestrate classroom learning experiences by bringing together knowledge from global teachers and take students from global information to contextual insights. Students have access to learning at their finger-tips and therefore, faculty are also faced with the challenge of constantly reskilling and re-inventing themselves.

  2. Understand the 21st Century Digitally Native Learner: If we look at it from the point of view of the learner, the social contract between the student and the teacher has changed; students’ expectations of teachers have also increased. Today’s students are far more digitally savvy and can multi-task, i.e. learn through videos while socially interacting online and being part of a classroom all at once. How do you evolve your classroom to cater to the changing learning and education needs of this 21st century learner? Here are some ways-

  • Understand how and why students learn to help you make informed decisions about curriculum and pedagogy.

  • Shift from ‘passive’ to ‘experimental’ pedagogy to make classroom learning active and application-oriented.

  • Adopt social and peer-to-peer learning methodologies to be where your student is.

  1. Prepare students for the new-age industry requirements: Technology is constantly evolving and jobs are changing rapidly. If you look at the top 20 jobs of 2030 (as per a report by WEF) you will see that you are trying to train students to prepare for jobs – more than 80% of which are new and unheard of today. Can you afford to ‘not change the way you teach?’

Today’s education is moving to a trend of ‘unbundling’ – content, curriculum, faculty and credentials. Today’s faculty and educational institutions should equip themselves to take the best content, blend it into the curriculum, learn from the best global faculty and give credentials that industry will recognize. By adopting the best of digital learning in the traditional classroom, blended MOOCs can become a ‘tradigital’ tool to evolve education to keep pace with learner and industry needs.

The IIMBx MOOCs Programme conducts Faculty Development Programmes on ‘Blending MOOCs in the Classroom’ to open up minds to asking the right questions on MOOCs and to foster adoption of MOOCs into traditional classroom teaching. For more details, visit https://www.iimbx.edu.in/

Note: This post is written to capture key insights shared by PD Jose, Professor of Startegy, and Chairperson – Digital Learning, IIMB, at a Faculty Development Programme conducted at Chandigarh University on 10th July 2017.

Paper Title: Talent management activities of disability training and placement agencies in India.

Abstract

This study seeks to outline activities of training and placement agencies in India aimed at employment of persons with a disability. We contend that persons with a disability are an underutilized human resource and that utilizing their abilities should be a key part of an inclusive approach to talent management. As there is little empirical research on this subject, our approach is exploratory and we seek to create a platform for further studies. A key finding of the study is the preference of agencies to engage in non-traditional and ad hoc approaches to build and showcase underutilized talent of those with a disability. Based on present findings and the contextual approach to talent management, a more comprehensive agenda for future research areas in inclusive talent management is outlined.

Paper Title: The shaping of sustainable careers post hearing loss: Toward greater understanding of adult onset disability, disability identity, and career transitions.

Abstract

Through this interview-based study with 40 respondents in the United States we have outlined enablers of career transitions and sustainable careers for professionals who have experienced severe hearing loss as adults. To sustain careers after adult onset disability, respondents engaged in a quest for meaning and big picture answers to ‘who am I?’ and ‘am I still successful?’ This included redefining themselves – e.g. I am now both a person with a disability (disability identity) and a successful professional (professional identity) – and career success (e.g. now I care about service to society as much as I care about material artifacts). Respondents also adopted new work roles where disability was a key to success (e.g. becoming an equal employment officer) and utilized social networks to continue being successful. Such redefining of work and networks supported the aforesaid quest for meaning and big picture answers. Findings not only indicate how individuals experience career success after a life-changing event but also help defamiliarize extant notions of ableism in workplace contexts.

Journal Title: Navigating identity duality in multinational subsidiaries: A paradox lens on identity claims at Hindustan Unilever 1959–2015.

Abstract

Multinational subsidiaries do not merely seek legitimacy within their dual institutional contexts; they also strive to articulate an organizational identity by drawing on institutional resources embedded in these dual contexts. We draw attention to the subsidiary’s identity duality and conceptualize it as a paradox, i.e., as the juxtaposition of the contradictory, interdependent, and persistent characteristics of the ‘global’ and the ‘local’ in the subsidiary’s identity. Using 57 years of archival data from Hindustan Unilever, the Indian subsidiary of Anglo-Dutch multinational Unilever, we observe changing patterns in the articulation of identity claims by subsidiary leaders and develop a process model of how subsidiaries navigate identity duality over time. We find that subsidiary leaders may use two modes of organizational identity work for this purpose – logic ordering (the articulation of identity claims that respond to contradictory institutional demands by privileging one and subordinating the other) and logic bridging (the articulation of identity claims that respond to contradictory institutional demands by effecting a Janusian integration of the said demands). Over time, and employing these modes of identity work, leaders at Hindustan Unilever sustained a dynamic balance between the dual cores of the subsidiary’s espoused identity.
