  摘要：We examine how different strategies can be used to protect global manufacturers from the prevalent issue of supplier copycatting in emerging markets. In particular, using a game-theoretical model, we consider a manufacturer that sells a product to an emerging market, which requires the completion of multiple tasks. The manufacturer can perform any of these tasks in-house or outsource any of them to an emerging market supplier. The former approach carries a higher cost, while the latter puts th...

  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...

  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...
• Incentives and Stars: Competition in Innovation Contests with Participant and Submission Visibility AI翻译

  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...

  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...

  摘要：Operations management (OM) has evolved to its current status due to the contributions of researchers in many fields including economics, finance, behavioral sciences, operations research/management science, mathematics, statistics, and computer science. Many of these contributors are Nobel laureates-winners of the highest academic award. The Nobel Memorial Prize in Economic Sciences is awarded to those with monumental works in economics. Yet, some winners have also made contributions to operat...
