(Forthcoming) "You Are What You Eat: An Empirical Investigation of the Relationship between Spicy Food and Aggressive Cognition", Journal of Experimental Social PsychologyRead Abstract >Close >The popular saying “you are what you eat” suggests that people take on the characteristics of the food they eat. Wisdom from ancient texts and practitioners of alternative medicine seem to share the intuition that consuming spicy food may increase aggression. However, this relationship has not been empirically tested. In this research, we posit that those who consume “hot” and “spicy” food may be more prone to thoughts related to aggression. Across three studies, we find evidence for this proposition. Study 1 reveals that those who typically consume spicy food exhibit higher levels of trait aggression. Studies 2 and 3 reveal, respectively, that consumption of, and even mere exposure to spicy food, can semantically activate concepts related to aggression as well as lead to higher levels of perceived aggressive intent in others. Our work contributes to the literature on precursors of aggression, and has substantive implications for several stakeholders, including marketers, parents and policy makers.

(2017) "Family Values and Inter-Institutional Governance of Strategic Decision Making in Indian Family Firms", Asia Pacific Journal of ManagementThomas Schmidheiny Centre for Family EnterpriseRead Abstract >Close >In this paper we use new venture creation in Indian family firms to explore the family firm as an inter-institutional system. We argue that in societies where the traditional family dominates social and economic life, the relationship between the two institutions, the firm and the family, is managed via inter-institutional logics. These inter-institutional logics help reconcile the tensions that often arise in the family firms during strategic decision-making. We use archival and interview data on thirty-six new ventures in eight Indian family firms to identify these logics. Our analysis shows that the interaction between firm and family institutional logics in Indian family firms generates four sub-logics: Economic, Expertise, Reputation and Attachment. These four logics are used to frame and screen new venture opportunities and justify resource allocation

Published PapersSubramanian, Krishnamurthy. (Forthcoming) "Localization of FDI flows: Evidence on Infrastructure as a critical determinant", Journal of Law, Finance and AccountingRead Abstract >Close >The localization of Foreign Direct Investment (FDI) to a few economies represents a puzzling aspect of international business. We study the provision of public infrastructure as a determinant of such localization. We employ unique data at the district level in India. We identify using variation: (i) among sectors within a district depending upon the sector’s propensity to attract FDI at the national level; and (ii) FDI into surrounding districts. We find that FDI inflows remain insensitive to changes in infrastructure till a threshold is reached; thereafter, FDI inflows increase steeply with an increase in infrastructure. This non-linear effect potentially explains why FDI remains restricted to a few countries.

(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.

Published PapersDevalkar, Sripad K., Sohoni, Milind G., Arora, Priyank. (Forthcoming) "Ex-post funding: How should a resource constrained non-profit organization allocate its funds?", Production and Operations ManagementRead Abstract >Close >We study the funds allocation problem for a resource-constrained non-profit organization (NPO) that implements social development projects for public good. In addition to raising funds from donors who contribute prior to project implementation (``traditional donors''), the NPO uses a novel approach, which we term as the ``ex-post funding'' approach, to also raise funds from donors who contribute based on the results delivered by the NPO (``ex-post donors''). In this approach, the NPO uses its initial funds to implement early phases of the project, creates ``results-certificates'' from the completed phases, and invites ex-post donors to purchase these certificates. The donations raised from selling the results-certificates are used to recover the NPO's own funds used in the project implementation. Operationalizing this approach is complicated when the project must incur a large fixed cost before any benefits are delivered by the project and the total benefit delivered is time sensitive. We show that for a given amount of initial funds available, there exists a threshold amount of funds that the NPO should raise from traditional donors before implementing the project phases so as to maximize the total expected benefit delivered. Through numerical studies, we analyze how the threshold of funds raised from traditional donors and the total benefit delivered vary with donor characteristics such as donor willingness to give and the proportion of donors who contribute prior to project implementation. Our numerical studies suggest that even with relatively small amount of initial funds, the NPO can deliver substantially higher benefit by using the ex-post funding approach when compared to using a traditional approach that requires the NPO to raise all the funds required upfront.

Published PapersVoleti, Sudhir., Dr. Seenu Srinivasan, Dr. Pulak Ghosh. (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
