  摘要：Sellers are conventionally generous with their return policies for valuation-uncertain products, such as experience products and new products. However, with the development of online review platforms, an increasing number of consumers are engaging in social learning by referring to others' reviews to reduce valuation uncertainty. In this study, we investigate how social learning interacts with sellers' return policies. There are three main conclusions. First, when sellers have a relatively hig...
• Saving migrants' lives at sea: Improving search and rescue operations AI翻译

  摘要：The present study focuses on the Mediterranean Sea migration crisis and investigates the effectiveness of search and rescue (SAR) operations alongside measures to reduce the number of deaths of migrants at sea. It also describes the stakeholders involved in SAR activities. The paper first analyzes secondary data and the results of 24 in-depth interviews in order to develop an analytical framework, which is then complemented by a system dynamics model to explore the complexity and interactions ...

  摘要：We study a coordinated clinic and surgery appointment scheduling problem for in-advance scheduling of surgical patients. Our models seek to provide timely access to care by coordinating clinic and surgery appointments to ensure that patients can see a surgeon in the clinic and (if needed) schedule their surgery within a maximum wait time target based on patient classes. There are different types of uncertainty including the number of appointment requests, whether a patient requires surgery, an...
• Credit Rating Prediction Through Supply Chains: A Machine Learning Approach AI翻译

  摘要：As supply chain channels physical, financial, and information flows as well as associated risks, a firm's supply chain information should be helpful in understanding and predicting its credit risks. Credit ratings, as an approximate but important measure of corporate credit risks, have been widely used by investors, creditors, and supply chain partners in their decision-making. This study studies the role of supply chain information in predicting companies' credit ratings. Using firm-level sup...

  摘要：Online innovation contests in which all current and potential contestants can view the identities of participating contestants and their submissions have become a popular format. Contestants who enter such a contest earlier than other contestants must weigh the potential costs of revealing their identities and submissions against the potential benefits of improving their submissions through emerging information and early engagement. In this study, we examine how top-ranked contestants or stars...
• Impact of Competitor Store Closures on a Major Retailer AI翻译

  摘要：We use a proprietary data set from a national US department store chain to investigate the impact of competitor store closures on a major retailer. The transaction level data set includes nearly 80 million transactions, corresponding to $2 billion in sales over a 25-month period. We find that store sales increase with respect to a store's proximity to closed competitor locations. More interestingly, we find that online channel sales also increase in geographic locations where competitors close...

  摘要：With over half a trillion dollars in trade credit flowing between firms in the United States, it is critically important for managers to understand how the trade credit that their firm receives and provides affect its value. Trade credit is a strategic investment in supply chain relationships that allows the recipient to make payment later rather than at the time of the sale. A firm provides trade credit to its downstream business customers and also receives trade credit from its upstream supp...
• Mobile App Adoption and Its Differential Impact on Consumer Shopping Behavior AI翻译

  摘要：The mobile application (app) market is one of the fastest growing markets in recent years. In this study, we investigate how app adoption changes customers' hotel booking behaviors using a dataset of around 16,000 randomly selected customers' hotel booking and stay information from one of the largest hotel chains in China. Our analyses find that customer purchase frequency and total sales increased after app adoption. Additional investigation shows that customers' search behaviors also evolved...
• Supply chain challenges in the post-Covid Era AI翻译

  摘要：In this paper, we reflect on the supply chain issues and operational challenges that we experienced through the various stages of the Covid-19 pandemic. We identify some phenomena that were attributable in some way to the pandemic, and apply core principles of operations management, and a simple numerical model, to explain and understand their occurrence. We highlight some key lessons and discuss implications for supply chain design and planning, to prepare for the next global disruption.
• Data-driven allocation of development aid toward sustainable development goals: Evidence from HIV/AIDS AI翻译
  作者：Jakubik, Johannes; Feuerriegel, Stefan

  摘要：Ending the HIV/AIDS epidemic is an important target of the United Nations Sustainable Development Goals (SDGs). To achieve it, countries worldwide donate large amounts of development aid (USD 15.18 billion annually). However, current practice in allocating development aid is largely based on decision heuristics and thus subject to inefficiencies. To address this problem, we aim to support managers of funding bodies in identifying cost-effective allocations of development aid and thus develop a...
