(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 PapersBatra, Rishtee Kumar., Ghoshal, Tanuka. (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.

Evidence from the cycle rickshaw rental market", Journal of Institutional Economics, 13 (3)Read Abstract >Close >Urban informal self-employment activities are known to be an important destination for rural-to-urban migrants engaged in multilocational livelihood strategies. Yet, the literature suggests that access to working capital required for these occupations may be a significant barrier for temporary migrants. This paper addresses this puzzle using data from a primary field study of the cycle rickshaw rental market in a central Indian city. Employing a multi-dimensional measure of migration and analysing both the driver and the owner-contractor sides of the cycle rickshaw rental market, we argue that informal rental markets may be critical to overcoming credit access issues for migrants.

Published PapersJain, Tarun. (2017) "Common tongue: The impact of language on educational performance", Journal of Economic History, 77 (2), 473-510Read Abstract >Close >This paper investigates the impact of official language policies on education using state formation in India. Colonial provinces consisted of some districts where the official language matched the district's language and some where it did not. Linguistically mismatched districts have 18.8% lower literacy rates and 27.6% lower college graduation rates, driven by difficulty in acquiring education due to a different medium of instruction in schools. Educational achievement caught up in mismatched districts after the 1956 reorganization of Indian states on linguistic lines, suggesting that political reorganization can mitigate the impact of mismatched language policies.

(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.

Published PapersMehra, Amit., Saha, Rajib. (2017) "Utilizing Public Betas and Free Trials to Launch a Software Product", Production and Operations ManagementRead Abstract >Close >Many software product firms release a public beta prior to launching its product. Public betas are adopted by innovator consumers and firms use free feedback from these consumers to improve the quality of the product. While trying out the public beta, innovators also learn their product preferences accurately. In addition, opinions expressed by the innovators about the software on public forums like blogs, etc., can introduce a perception bias about the product's quality among the imitator consumers. Therefore, there are demand and cost side trade-offs in introducing public betas. In addition to public beta, firms can introduce product trials along with the product. Product trials serve as a learning mechanism for all consumers (innovators and imitators), unlike in the case of public betas where this benefit accrues only to innovators. We examine the firm's optimal strategies to introduce public beta and/or product trial. We show that introducing public beta does not necessarily result in a higher-quality product. However, even when the quality is lower, consumer surplus and social welfare can be higher. Interestingly, while introducing public beta in addition to trial may appear to be optimal, it may not always be so. We show that similar results hold for products with network effects. We also find that even though the marginal value of quality to consumers is higher for products with network effects, the quality of the product can sometimes be lower than the quality in absence of network effects.

(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

(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 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.

(2015) "Optimizing tuberculosis case detection through a novel diagnostic device placement model: The case of Uganda", PLOS ONE, 10 (4), e0122574Read Abstract >Close >Background The Xpert MTB/RIF (Xpert) device is being widely adopted. Analysisis needed to guide the placement of devices within health systems to optimize tuberculosis (TB) detection. Methods We used epidemiologic and operational data from Uganda to perform a model-based comparison of different placement strategies for a limited number of Xpert devices, which included: 1) Health center level (sites ranked from highest to lowest level), 2) Smear volume (sites ranked from highest to lowest), 3) Antiretroviral therapy (ART) volume (sites ranked from greatest to least patients on ART), 4) External equality assessment (EQA) performance (sites ranked from worst to best smear microscopy performance) and 5) TB prevalence (sites ranked from highest to lowest). Outcomes included CDR, detection of multi-drug resistant TB, and number of sites requiring device placement. Results 139 sites serving 87,600 TB suspects were modeled. Placement strategies that prioritized sites with higher TB prevalence and worse EQA performance led to a greater CDR compared to other strategies. They resulted in an incremental CDR of 4.9-12.3% compared to status quo (microscopy alone).  Diagnosis of MDR-TB was greatest in the TB Prevalence strategy, with a 2.6-3.4% higher rate compared to the next best strategy. The number of Xpert devices required for the TB Prevalence, EQA Performance, and ART volume strategies was greater than the other strategies for the same level of coverage. Results remained robust over variation in clinical algorithm, EQA accuracy, and return for test results. Conclusion In Uganda, placement of Xpert devices in sites with high TB prevalence and poor EQA performance yielded the highest TB case detection rate. These results represent a novel use of program level data to inform the optimal placement of new technology in resource-constrained settings.
