Title |
Survival of the capable: The interplay of survival-related capabilities across the firm lifecycle |
Co-authors, Collaborators |
Prof. Ansgar Richter (Frankfurt School of Finance & Management), and Amit Karna (IIM Ahmedabad) |
Abstract |
Firms require both operational and dynamic capabilities for their survival. Operational capabilities are vital for short-term survival, while dynamic capabilities enhance evolutionary fitness required for long-term survival. However, prioritizing short-term survival can compromise long-term evolutionary fitness and vice versa. In this study, we ask whether the survival-enhancing benefits of capabilities vary across a firm’s lifecycle. We theorize that while both operational and dynamic capabilities are important for survival, their relative importance depends on the lifecycle stage. Operational capabilities are more important during the initial phases of the lifecycle, whereas dynamic capabilities become increasingly important in later stages. Using panel data regression on a longitudinal sample of U.S. public firms from 1981 to 2023, we find support for these predictions. The findings contribute to the literature on firm capabilities and survival. We also derive practical insights for executives, suggesting which capabilities to prioritize at different stages of the firm lifecycle, particularly given the resource-intensive and path-dependent nature of capability development. |

Title |
A dual-factor concept analysis of acceptance and resistance to online teaching by school-teachers |
Co-authors, Collaborators |
Prof. Aditi Bhutoria, IIM Calcutta |
Abstract |
Online teaching can be used to develop innovative educational services for promoting quality education. While previous research has discussed the factors that influence teachers to teach online, the combination of both acceptance and resistance factors to teach online has rarely been considered simultaneously. This research model delves into the dual factor concepts of ‘facilitators’ and ‘inhibitors’ of teacher’s intention to teach online. Extending the Technology Acceptance Model (TAM) to include the online teaching self-efficacy in the facilitating factors and resistance to change, technostress, and frequency of negative critical incidents during prior use in the inhibiting factors, this model questions what factors and how these factors influence school-teacher’s intention to use online teaching. |

The Frontiers of Labour Market Intermediation |
Co-authors, Collaborators |
Prof. Rajalaxmi Kamath, IIM Bangalore |
Abstract |
Today, labour market intermediaries - in their most sophisticated format of a human resource/staffing company- are not only forging employment relations but are the employers of record. In an eight-month-long work ethnography in one of the staffing companies, we understand how they hire, place, and manage the labour force for various client organizations. We give insights on their prominent client organizations, the job roles routed through staffing companies, their rationale for doing so and its implications for India's labour market. |

Title |
A Hierarchy of Second Order Cone Programming relaxations for zero-one Quadratically Constrained Quadratic Programming Problems. |
Co-authors, Collaborators |
Prof. Jitamitra Desai, IIM Bangalore |
Abstract |
Quadratically Constrained Quadratic Programming (QCQP) problems with binary variables frequently arise in diverse applications such as Portfolio Optimization, Facility Location, and Capital Budgeting. Traditional global optimization techniques address these problems by constructing convex or linear relaxations and integrating them into an exhaustive search framework, where the lower bound of the objective function is evaluated at each iteration. This paper introduces a novel reformulation approach to enhance existing methods, particularly those based on Reformulation-Linearization Technique (RLT) and Second-Order Cone Programming (SOCP). Our approach demonstrates that the effectiveness of the formulation is contingent upon the degree of terms used in the reformulation, with higher degrees yielding tighter approximations that ultimately converge to the convex hull of the original problem. We present computational results comparing our method with standard techniques, such as RLT and Semidefinite Programming (SDP), using benchmark instances to validate its efficacy. |

The Relevant Third: Threat of Coalition and Economic Development |
Co-authors, Collaborators |
Sourav Bhattacharya (IIM Calcutta), Somdeep Chatterjee (IIM Calcutta), Pushkar Maitra (Monash University) |
Abstract |
We examine the impact of political competition on economic development in a multi-party setting by constructing a novel measure of competition: threat of coalition. We define a constituency as competitive when there is a ‘relevant’ third-position candidate, i.e., the ex-post vote share of the third-ranked candidate exceeds the winning margin. Using data from Indian Legislative Assembly elections and a regression discontinuity (RD) design, we show that constituencies with a barely ‘relevant’ third witness a 1.2—3.5 percentage points increase in nightlights (our measure of economic development). The main mechanisms are a higher availability of public goods and reduced reported crimes in constituencies with a relevant third. We rule out other channels by showing that there is no effect when the threat of coalition is not credible. |

IT software coordination in networks |
Co-authors, Collaborators |
Sanjith Gopalakrishnan (Desautels Faculty of Management, McGill University), Sriram Sankaranarayanan (Indian Institute of Management, Ahmedabad) |
Abstract |
We investigate the problem of technology adoption by players in a networked environment. Modeling the environment as a directed network, we assume that each player faces a fixed cost for adopting a technology and an incoordination cost for differing from the technology of its neighbors. We characterize the network-optimal technology adoption problem and show that computing the network-optimal adoption strategy is computationally challenging. We also focus on a variant of the problem where the technologies are on a continuum. We compute the network-optimal and equilibrium costs, offering insights for efficient network coordination. |

Effect of Education on Women’s Time Use: A Causal Analysis using DPEP. |
Co-authors, Collaborators |
Soham Sahoo, Loughborough University & IIM Bangalore and Hema Swaminathan, Asian Development Bank & IIM Bangalore |
Abstract |
This paper examines the impact of education (captured through District Primary Education Programme) on Indian women’s time allocation. We use data from the 2019 Time Use Survey and employ a difference-in-difference (DID) framework for this analysis. While DPEP increased women’s completion of primary schooling, it led to gendered shifts in workload. Women spent more time on domestic work, while men spent more time on employment. We find no significant change in the intra-couple time allocation patterns. |

Venture Capital Syndicate Centrality and IPOs: Information and Investor Attention |
Co-authors, Collaborators |
Sudhakara Reddy Syamala, Professor, Finance & Control Group, Indian Institute of Management Calcutta |
Abstract |
We study the impact of how well connected the Venture Capital syndicate investing in a particular IPO firm is to the entire Venture Capital network, on voluntary and aftermarket underpricing, investor attention, valuation and initial day performance of the IPO. We follow social networks literature and develop a measure for cumulative centrality of VC syndicates. The Indian setting offers us the advantage of transparency, thus enabling us to examine investor attention by category, and also the actual underpricing voluntarily carried out by the underwriter. We find that centrality, in fact, causes higher underpricing which is voluntarily carried out by the underwriter and though institutional investor attention is positively impacted, retail investor attention and initial day returns reduce in increasing centrality of the backing syndicate. Secondary market valuation is positively impacted by VC network centrality. Results are robust to different definitions of centrality and other explanations. |

Encroachment or Entitlement? Negotiating Public Space for Business Sustenance |
Co-authors, Collaborators |
Arun Sreekumar, Asst Prof of Marketing, IIM A |
Abstract |
In this multi-sited qualitative study, we explore the ways in which poor retailers negotiate access to a particular public resource, public space. Specifically, we document four main ways of negotiation that result from the interaction, both conflict and shared interest, of consumers, the public, the government, and the retailers. We demonstrate how the common nature of space stimulates contestations among various social actors and fuels forms of agency and hardships for informal retailers. |

Title |
Electric versus Flex-fuel Vehicles – The impact of government policies on automakers’ choice between green technology alternatives. |
Co-authors, Collaborators |
Haritha Saranga, IIM Bangalore and Sreelata Jonnalagedda, IIM Bangalore |
Abstract |
Green vehicles like EV and FFV are expected to be the future, however, prohibitively high investment costs force automakers to make choice between alternative technologies. We develop an analytical model to study an automaker’s choice to invest in EV or FFV where a fraction of consumers are endowed with conventional vehicle. Our findings suggest that automakers should prioritize EVs when the fraction of endowed customers is low, and the resale value is above a certain a threshold but not very high. Demand incentives and emission taxes influence portfolio mix and market coverage, resulting in a trade-off between total emission reduction and consumer welfare. |

Reigniting the flame: Sustaining Usage Through Intermittent Releases of In-game Content |
Co-authors, Collaborators |
Prof. Soumyakanti Chakraborty, Management Information Systems group, Indian Institute of Management Calcutta. |
Abstract |
Downloadable contents (DLCs) are additional in-game contents that developers release periodically to sustain the interest of users. In this paper, we study the effect of these DLC releases on the usage of a game by analysing actual usage data from 241 DLCs released over a period of 12 years. We use a quasi-experimental analysis to determine the effect on usage, and also investigate the effect of different DLCs categories on usage. We also study the effect of the different categories of game developers, indie and AAA, on the relationship between DLC release and usage. Results indicate that different categories of DLCs have distinct effects on usage. We also find that the release of DLCs of indie games have a greater impact on usage as compared to AAA games. We compare and contrast our results with the extant literature and provide insightful guidelines to game developers on managing DLC releases. |

Cooperative Adoption of Supply Chain Traceability |
Co-authors, Collaborators |
Sanjith Gopalakrishnan (Desautels Faculty of Management, McGill University), Sriram Sankaranarayanan (Indian Institute of Management, Ahmedabad) |
Abstract |
We investigate firms' adoption of traceability technology in supply chain networks. Adopting a cooperative game-theoretic approach, we develop a cost sharing mechanism implementable via transfer payments to upstream suppliers. We show that the cost sharing mechanism satisfies certain formal fairness properties, and, when efficient, supports the optimal traceability adoption strategy. Our findings also extend to a model that allows firms to benefit from partial traceability in their upstream supply chain. |
