摘要:We consider the anesthesiologist staff planning problem for operating services departments in large multi-specialty hospitals without limit on anesthesiologist supply, where the planner makes monthly and daily decisions to minimize total costs. Each month the staff planner decides the number of anesthesiologists on regular duty and an on-call consideration list for each day of the following month. In addition, each day, the staff planner decides how many on-call anesthesiologists to call for t...

摘要:When a patient's illness perception is inconsistent with a doctor's diagnosis, she may seek opinions from multiple doctors without referrals, a behavior called doctor shopping. In this study, we model and derive patients' optimal doctor shopping decisions. After each visit, patients update their beliefs about their health status following the Bayes' rule. We show that the patients' doctor shopping decisions are critically affected by the diagnosis accuracy, the relative value of identifying a ...

摘要:Do firms suffer from negative long-term business performance after being exposed for violating environmental regulations? We empirically examine this question using all 1542 environmental incidents committed by 418 public Chinese manufacturers listed on the Shanghai/Shenzhen Stock Exchange from 2004 to 2013. We use the Coarsened Exact Matching to match a sample firm with (exposed) environmental incidents with a control firm that exhibits the same characteristics in our sample. Our comparative ...

摘要:This research considers situations in which buyers pay to reserve their suppliers' capacity for future use. The study specifically explores whether suppliers should provide transfer rights, allowing buyers unable to use all of their reserved capacity to transfer the excess to another buyer, and whether they should charge a transfer fee. The study finds that, in most cases, the supplier maximizes financial outcomes when the buyer releasing the excess capacity keeps most of the retail-level prof...

摘要:Storage assets are critical for physical trading of commodities under volatile prices. State-of-the-art methods for managing storage facilities such as the reoptimization heuristic (RH), which are part of commercial software, approximate a Markov Decision Process (MDP) assuming full information regarding the state and the stochastic commodity price process and hence suffer from informational inconsistencies with observed price data and structural inconsistencies with the true optimal policy, w...

摘要:In the presence of successive product generations, most consumers are repeat buyers who may decide to purchase a future product generation even before its release. Therefore, after a new product generation enters the market, its sales often exhibit a declining pattern, which renders traditional diffusion models unsuitable for characterizing consumers' decisions on upgrade timing. In this study, we propose an Exponential-Decay proportional hazard model (Expo-Decay model) to predict consumers' t...

摘要:Due to the ongoing and dramatic growth in the volume of consumer returns, retailers continue to struggle with the trade-off in returns service strategies between implementing stricter return policies to lower operational costs and environmental footprint versus providing customers with lenient return policies to positively stimulate customers' value perceptions and patronage intentions. This paper argues that effective management of this trade-off requires a deep understanding of the process t...

摘要:Prior studies report mixed evidence on the impact of customers' bargaining power on supplier performance. We shed light on this mixed evidence by considering the moderating role of strategic fit. A strategically aligned supplier can provide long-term benefits to the customer. As a result, powerful customers may trade off the short-term benefits obtained through supplier concessions with the long-term benefits derived from strategic fit. Thus, strategic fit can mitigate the negative impact of c...

摘要:This study centers on the roles of marketing and operations capabilities in preventing future recalls. However, prior literature identifies operations capability as critical for recall prevention, the current research highlights the equivalent importance of marketing capability. Furthermore, rather than limiting marketing's role to damage control efforts after a recall, this study identifies its potential for preventing future recall incidents. With research conducted in the consumer packaged ...

摘要:We study the optimal design of reservations for a firm with limited capacity. The firm faces a random number of customers, each of whom has a random valuation for service. The reservation policy has two components: pricing and overbooking. For the former, the firm charges a reservation fee (at the time of reservation) and a service price (at the time of service). For the latter, the firm imposes a booking limit that caps the number of reservations it sells. Given the firm's reservation policy,...
