The School’s research output in the last decade has been both significant and considerable, as testified by our AACSB accreditation in 2011. We take great pride in the fact that our faculty have contributed more than 150 articles to reputed academic and practitioner journals.

In the past few years, ISB faculty members have published over 60 papers in top-tier journals. Our faculty have received numerous coveted research grants awarded by premier academic institutions, research centres, corporate houses and reputed foundations such as the Bill and Melinda Gates Foundation, Ford Foundation, MacArthur Foundation, WWF, McCombs School of Business, UT-Austin and others. These awards attest to the scope, depth and impact of the research conducted at the ISB.

(Forthcoming) "Fill Up Your Senses: A Theory of Self-Worth Restoration through High Intensity Sensory Consumption", Journal of Consumer ResearchCentre for Emerging Markets SolutionsRead Abstract >Close >It is well known that individuals engage in reactive consumption to address self-discrepancy and self-threat and that this consumption may be either symbolically related to the nature of the threat or may occur in an unrelated domain. This research proposes a theory for self-worth restoration through the consumption of high intensity sensory stimuli. Four studies demonstrate that not only do individuals facing self-threat prefer high intensity sensory consumption (HISC) but also this consumption restores their self-worth. This propensity for HISC is negated after individuals are allowed to engage in additional self-affirmation tasks. The findings are documented in both the visual domain (as evidenced by a preference for more intense and saturated colors) and the auditory domain (as evidenced by a preference for louder audio levels). The consumption of high intensity sensory stimuli elevates individuals’ arousal levels, which in turn minimizes rumination on thoughts related to the threat and thus restores one’s self-worth. The distractive nature of HISC and its subsequent impact on self-worth restoration is shown to operate regardless of the valence of the sensory consumption. Finally, the propensity for HISC is negated after individuals experience an arousal-elevating threat, providing additional support for the underlying process.

(Forthcoming) "An Approach to Improve the Predictive power of Choice - Based Conjoint Analysis", International Journal of Research in Marketing Read Abstract >Close >We propose a method that (i) robustly estimates of consumers’ part-worths, (ii) flexibly and parsimoniously captures respondent heterogeneity based on part-worth estimates, (iii) offers superior predictive power based on holdout sample analysis, within a Choice based Conjoint (CBC) problem context such that the proposed method: (a) Applies readily to non-metric (discrete choice) data and (b) incorporates the ‘outside option’ or ‘none chosen’ alternative. We develop an extension of the Bayesian semiparametric Dirichlet process method, called the Mixture of Dirichlet process (MDP) to achieve the objectives of the paper. We demonstrate our model on a set of 5 different CBC datasets having different respondent numbers, product profiles and attributes evaluated. We find the proposed model consistently outperforms the best available benchmarks in fit and predictive validity.

Published PapersVoleti, Sudhir., Kopalle, Praveen K., Gangwar, Manish. (Forthcoming) "Why the Dynamics of Competition Matter for Category Profitability", Journal of Marketing Read Abstract >Close >Category Management (CM) has becomes a widespread trade practice in recent years. A category manager's decision problem is complex and multi-faceted owing to demand dependencies across products and across time. Extant research on CM has typically focused on one or the other of these dependencies, but seldom both. The authors address this gap in the extant empirical literature on CM by presenting a competition framework that reconciles cross-sectional breadth (large numbers of SKUs in any given period) with longitudinal depth (demand effects across time). The endeavor is to offer retailers a general, realistic and practical CM approach by comprehensively accounting for competitive effects. The authors demonstrate their approach on real-world data in the beer category for a midsize grocery chain in the US Northeast. Upon determining the optimal weekly prices for the entire assortment over 23 weeks, the authors report a profit yield that is 13% more than in the benchmark logit model and 16% more than in the retailer's current EDLP pricing policy

Published PapersBala, Ram., Kunnumkal, Sumit M., Sohoni, Milind G. (2016) "Evergreening and Operational Risk Under Price Competition", Naval Research Logisitcs, 63 (1)Read Abstract >Close >“Evergreening” is a strategy wherein an innovative pharmaceutical firm introduces an upgrade of its current product when the patent on this product expires. The upgrade is introduced with a new patent and is designed to counter competition from generic manufacturers that seek to imitate the firm's existing product. However, this process is fraught with uncertainty because the upgrade is subject to stringent guidelines and faces approval risk. Thus, an incumbent firm has to make an upfront production capacity investment without clarity on whether the upgrade will reach the market. This uncertainty may also affect the capacity investment of a competing manufacturer who introduces a generic version of the incumbent's existing product but whose market demand depends on the success or failure of the upgrade. We analyze a game where capacity investment occurs before uncertainty resolution and firms compete on prices thereafter. Capacity considerations that arise due to demand uncertainty introduce new factors into the evergreening decision. Equilibrium analysis reveals that the upgrade's estimated approval probability needs to exceed a threshold for the incumbent to invest in evergreening. This threshold for evergreening increases as the intensity of competition in the generic market increases. If evergreening is optimal, the incumbent's capacity investment is either decreasing or nonmonotonic with respect to low end market competition depending on whether the level of product improvement in the upgrade is low or high. If the entrant faces a capacity constraint, then the probability threshold for evergreening is higher than the case where the entrant is not capacity constrained. Finally, by incorporating the risk-return trade-off that the incumbent faces in terms of the level of product improvement versus the upgrade success probability, we can characterize policy for a regulator. We show that the introduction of capacity considerations may maximize market coverage and/or social surplus at incremental levels of product improvement in the upgrade. This is contrary to the prevalent view of regulators who seek to curtail evergreening involving incremental product improvement.

(Forthcoming) "Social Identity and Governance: The Behavioral Response to Female Leadership", European Economic ReviewCentre for Learning and Management PracticeRead Abstract >Close >Women in leadership positions make different policy choices compared to men. An increase in the proportion of female leaders can therefore alter both the nature of governance as well as the types of public services provided. However, whether women are effective as leaders remains an open question. In this paper, we use data from an artefactual field experiment and individual and community surveys from 40 Indian villages to examine the following questions: (i) is there a backlash by men towards women in leadership positions? (ii) how do female leaders react to males perceptions about women as leaders? (iii) does the presence of female leaders differentially affect the behavior of males and females? We find that there is indeed a male backlash against female leaders. Our results suggest that resistance to women leaders is due to violation of social norms, not due to potential inefficacy of women leaders. We also find that increased exposure to female leaders reduces the extent of bias.
