Published Papers

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) "Demand Curves For Stocks Do Not Slope Downwards: Evidence Using an Exogenous Supply Shock", Journal of Banking and FinanceCentre for Analytical FinanceRead Abstract >Close >We analyze the price impact of an exogenous share sale by inside blockholders, who were forced to sell a part of their shareholdings due to a regulatory change in India. The affected firms experience a negative excess return of 4.5% during the issue week. Crucially, the price impact reverses in about 55 to 75 days after the event. Our results are consistent with the view that the long term demand curves for stocks are at: a view echoed by classical finance theories. The short term price reaction to a sale is likely to be a result of temporary price pressure.

(Forthcoming) "Data science applications in Indian agriculture", Production and Operations ManagementRead Abstract >Close >Agricultural supply chains in the developing world face the daunting task of feeding a growing population in the coming decades. Along with the provision of food, sustaining livelihoods, enhancing nutrition and the ability to cope with rapid changes in the environment and marketplaces are equally important to millions of small farmers. Data science can help in many ways. In this article, we outline the beginnings of data science applications in Indian agriculture. We cover various initiatives such as data collection, visualization and information dissemination and applications of algorithmic data analysis techniques for decision support. We describe one application under development that provides timely price information to farmers, traders and policy makers.

Published PapersDevalkar, Sripad K., Anupindi, Ravi.,Sinha, Amitabh. (Forthcoming) "Dynamic Risk Management of Commodity Operations: Model and Analysis", Manufacturing & Service Operations Management, INFORMSRead Abstract >Close >We consider the dynamic risk management problem for a commodity processor operating in a partially complete market and facing both price uncertainty and significant financial distress costs. The firm procures an input commodity and processes it to produce an output commodity over a multi-period horizon. We use a time-consistent risk measure to approximate the firm’s financial distress costs in a tractable manner and use financial trading to assign a market-based value to the firm’s operational cash flows. We show that the resulting optimal operational policy has the same price and horizon dependent threshold structure that characterizes the known optimal policy when markets are complete or financial distress costs are small. Through numerical studies, we (i) quantify the value of using the optimal operational policy rather than a myopic policy and a policy that neglects to model, even approximately, financial distress costs, finding that this value is significant for firms that face moderate financial distress costs and have excess procurement capacity; (ii) establish that more acute financial distress costs reduce the firm’s throughput; and (iii) show that the benefit of financial hedging is considerable.

Published PapersSaha, Rajib., Seidmann, Abraham.,Tilson, Vera. (2018) "The Impact of Custom Contracting and the Infomediary Role of Healthcare GPOs", Production and Operations ManagementRead Abstract >Close >Manufacturers and distributors of expensive implants and other medical supplies often require buyers to sign non-disclosure agreements treating all information concerning negotiated prices as trade secrets. Such agreements make it difficult for hospitals to obtain accurate pricing benchmarks. To save on procurement costs and to obtain pricing information, most hospitals in the United States join group purchasing organizations (GPOs). GPOs are believed to lower procurement costs by aggregating hospitals’ demand. Whether GPOs indeed add value to the healthcare supply chain and produce actual savings for hospitals are debated policy issues, as evidenced by the ongoing discussions on the topic in the U.S. Congress. Some hospitals procure using GPO contracts, and some try to improve on prices available via GPO contracts, negotiating custom contracts directly with the GPO vendors. Using a game-theoretic model, we prove that GPOs that operate independently and allow for custom contracting limit the benefit of demand aggregation to smaller hospitals only. The larger hospitals gain primarily from using the GPO as an infomediary to obtain critical pricing information benchmarks. Our results further explain why the introduction of custom contracting lowers the value of access to this pricing information for the hospitals, and how the savings through custom contracting can be misleading. We reveal how GPO vendors can exploit information asymmetry about their prices and earn even higher profits, and why, contrary to the industry’s belief, the resulting savings are never higher for any hospital, not even for the larger ones when the GPOs allow custom contracting.
