Can private jets help save lives? Yes. Can short videos nudge next‐of‐kin to donate more? Also, yes. How has an outsider to the transplantation system, with no previous knowledge or expertise in (any aspect of) healthcare, managed to make a difference? Is imagination really more important than knowledge? In this invited article, I will briefly describe two innovations—OrganJet and Nudge Videos—that I have implemented in the US Transplantation System that have extended the lives of many.

“…While Organ Transplantation is indeed a serious topic, I agree with Voltaire in believing that: Solemnity is a disease. I hope the playfulness (Tayur, 2017) of my writing does not mask the seriousness of the issues, nor detract from the two innovative initiatives that have extended many human lives.…”

“…The studies on product variety often bridge the domains of operations management and marketing (Kumar et al 2021, Xiao et al 2014. While increased product variety can lead to higher inventory costs Terwiesch 2017, Wan et al 2020) and complexity in operations (Fisher and Ittner 1999, Shunko et al 2018, Swaminathan and Tayur 1998, Ton and Raman 2010, Yunes et al 2007, Zhou and Wan 2017, enhanced product variety renders more options to cater to consumers' heterogeneous preferences and thus boosts sales (Tayur 2017, Wan et al 2012.…”

Gaining From Losing a Competition in Product Variety

This paper studies the impact of a competing firm’s substantial expansion in product variety, achieved through modularity and delayed differentiation, on the sales and inventory of the focal firm in the market. Intuitively, the firm’s sales are expected to decrease when a competitor increases its product variety, as existing consumers are drawn to the greater range of competing products, resulting in a substitution effect. However, we also emphasize a simultaneous spillover effect, where the dramatic increase in a competitor’s product variety can expand the overall market for all firms (including the focal firm) by attracting new consumers to the market. The net impact thus depends on the tradeoff between the substitution effect and spillover effect, forming an empirical question. To explore this tradeoff and quantify the net impact of a competitor’s substantial increase in product variety on the focal firm’s sales and inventory, we exploit the launch of Coca-Cola’s Freestyle dispenser that offers over 120 beverage products via modularity and delayed differentiation. Our analysis focuses on the treatment effects of the launch of Freestyle on changes in the focal firm’s sales quantity, sales dispersion, and inventory levels. Contrary to common intuition, we find that the focal firm’s total sales remain unchanged following the launch of Freestyle dispensers, but its sales dispersion increases by 2.2%, which in turn leads to a 1.0% increase in inventory levels at distribution centers. The unchanged total sales and increased sales dispersion imply a redistribution of sales among the focal firm’s stock keeping units (SKUs). By analyzing data at the SKU level and the business customer level, we uncover the mechanism behind this sales re-allocation: a 1.9% increase in the sales of the focal firm’s long-tail products at the expense of its star product sales. Meanwhile, we identify a 0.9% increase in sales to retailers and entertainment locations, while sales to restaurants decline. These empirical results help disentangle the substitution and spillover effects on the focal firm’s sales resulting from its competitor’s substantially increased product variety. Managerial implications derived from these findings are discussed.

Accepted by: Aris Syntetos Can mathematical research from a business school professor that is published in academic journals also substantially improve actual industrial practice in global supply chains? Yes. Can mathematics and operations management help improve fairness in access to organ transplants? Yes, again. Can mathematics developed for business applications facilitate the development of new types of quantum hardware? Also, yes. I have three main messages in this invited essay: (1) free yourself from self-imposed constraints and explore a wider range of new problems and arcane mathematics; (2) be bold and imaginative in developing novel solutions and (3) implement your ideas in practice, scaling them with a channel partner.
