摘要：Hospital-physician integration has been increasingly considered a potential solution for the underlying challenges hospitals face as they are adapting to value-based healthcare services. We adopt an activity-based measure of integration (ABI) to investigate the relationship between integration and care outcomes, namely in-hospital mortality risk, length of stay (LOS), and 30-day readmission risk. ABI is measured based on a group of physicians who handle a specific procedure, coronary artery by...

摘要：Educational equity serves as a cornerstone for a fair and flourishing society. However, existing research consistently highlights the presence of educational disparities between developed and developing regions. Remote learning, a transformative educational approach altering knowledge dissemination and access, takes center stage. Our study delves into the potential of remote learning to bridge this educational divide. Analyzing students' performance in China's National College Entrance Examina...

摘要：Achieving cognitive coordination in cross-functional teams is a perennial challenge in organizations. It is especially challenging in the context of information systems, where strategic alignment remains a top concern of leaders despite decades of research on the topic. In this study, we develop and empirically validate a theoretical model that explores the role of communicating about performance metrics in fostering cognitive coordination between the Chief Information Officer (CIO) and top ma...

摘要：We consider a supply chain where multiple suppliers and a manufacturer contribute to the assembly of a product (through providing components or labor). The product fails if any of its components (or elements of work) fails, but finding the faulty component can be prohibitively difficult. We study group warranty contracts for the manufacturer to induce suppliers to improve their quality levels. When information is symmetric and the manufacturer can contract on his own quality level, we show tha...

摘要：Firms use social media as a great marketing tool and a convenient platform to deliver customer service. However, due to its public and social nature, social media tends to amplify a brand's successes as well as failures. Reluctant to subject their customer service to public scrutiny, firms are increasingly turning to private messaging on their social media channels for customer service conversations, which amounts to a reincarnation of traditional customer service in the social media era. None...

摘要：This article studies an appointment scheduling problem where a service provider dynamically receives appointment requests from a random number of customers. By leveraging the randomness of the number of potential customers, we develop a nonsequential appointment scheduling policy as an alternative to the conventional first-come-first-served (FCFS) policy. This allows for more flexibility in managing appointment scheduling. To calculate the optimal policy, we develop a branch-and-bound algorith...

摘要：Cloud Kitchens are delivery-only facilities that house multiple restaurants. Food-delivery platforms operate such kitchens to exploit two advantages: (a) Location advantage, arising due to a cloud-kitchen's central location-this enables lower delivery times to customers. (b) Consolidation advantage, which accrues when multiple restaurants choose to co-locate at the cloud kitchen-this enables the platform to use a common pool of delivery drivers, thereby reducing costs. However, a cloud-kitchen...

摘要：We study the assortment optimization problem under general linear constraints, where the customer choice behavior is captured by the cross-nested logit model. In this problem, there is a set of products organized into multiple subsets (or nests), where each product can belong to more than one nest. The aim is to find an assortment to offer to customers so that the expected revenue is maximized. We show that, under the cross-nested logit model, the unconstrained assortment problem is NP-hard ev...

摘要：Governments across the developing world are adopting digital technologies to improve the performance of public sector supply chains. However, empirical evidence regarding the impact of these technologies on performance is mixed. In this paper, we evaluate the impact of using biometric authentication (BA) devices on the performance of India's food security program. The program aims to deliver subsidized food grains to nearly 160 million low-income households through approximately 500,000 fair p...
