摘要：The revolution in information technology has provided the research community in operations management (OM) with new areas to explore and many new avenues to develop. In recognition of this, many editors of OM journals strive to publish new ideas. These two forces generate strong motivation, but many young OM scholars find it difficult to find new OM research ideas. To address this challenge, I describe three simple thought processes (or approaches) that I have learned and used to identify new ...

摘要：This paper studies how service providers can design social interaction among participants and quantify the causal impact of that interaction on service quality. We focus on education and analyze whether encouraging social interaction among students improves learning outcomes in massive open online courses (MOOCs), which are a new service delivery channel with universal access at reduced, if not zero, cost. We analyze three randomized experiments in a MOOC with more than 30,317 students from 18...

摘要：Recent platforms, like Uber and Lyft, offer service to consumers via self-scheduling providers who decide for themselves how often to work. These platforms may charge consumers prices and pay providers wages that both adjust based on prevailing demand conditions. For example, Uber uses a surge pricing policy, which pays providers a fixed commission of its dynamic price. With a stylized model that yields analytical and numerical results, we study several pricing schemes that could be implemente...

摘要：Online purchases constitute about one-tenth of U.S. retail sales. The supply chains that support online retailing are fundamentally different from those that support traditional brick-and-mortar stores. Traditional solutions are not always appropriate to solve online retailing's operations problems; thus, there is an opportunity to understand and improve these novel supply chains. One key characteristic of the inventory systems for online retailing is demand spillover, whereby a stockout at a ...

摘要：Phase III clinical trials are expensive and require enrolling and treating hundreds or thousands of patients at many sites. The time and cost required to do so are uncertain, as is the economic value of the drug upon completion. We consider the problem of determining when and how many test sites should be opened and the rate at which patients should be recruited. We model the problem as a discrete time, discounted dynamic program with the objective of maximizing the expected net present value ...

摘要：Alliances for new product development have been studied extensively in the operations management literature. Alliances between an innovator and a partner create value by utilizing their complementary capabilities. In this paper, we seek to understand what drives the alliance structure: the choice between collaborative alliances where the parties exert joint efforts and sequential alliances where, for the most part, the partner takes over going forward. Our analysis of a data set of over 2,000 ...

摘要：We analyze how performance metrics that contain equivalent information affect actual decisions. We consider two such performance metrics from supply chain management, days of supply and inventory turn rate, where one is the inverse of the other. We argue that individuals' assessment of performance is also affected by the metric as opposed to solely based on the inventory value that actually matters. We perform three laboratory studies and analyze how decisions are affected by the metric used t...

摘要：To analyze incentives for investing in the capacity to generate renewable electricity, we model the trade-off between renewable (e.g., wind) and nonrenewable (e.g., natural gas) technology. Renewable technology has a higher investment cost and yields only an intermittent supply of electricity; nonrenewable technology is reliable and has lower investment cost but entails both fuel expenditures and carbon emission costs. With reference to existing electricity markets, we model several interrelat...

摘要：The posterior price-matching policy, whereby a firm promises to reimburse the price difference to a customer who purchases a product before the firm marks it down, has been used in practice. The extensive literature has offered the following explanations for why posterior price matching is adopted: to reduce inventory, to soften competition, to price discriminate consumers, and to eliminate consumer strategic waiting incentives. In this paper, we provide a novel explanation and investigate the...
