摘要：This article examines supply-base configuration, supplier selection, and order allocation under supply risk and downstream rivalry. We develop a Cournot duopoly model in which two firms sell partially substitutable products and procure a critical input from two unreliable suppliers with asymmetric cost-risk profiles and correlated yield risks. We formulate a two-stage game: firms first choose their supply bases either endogenously or under a one-sided sourcing-flexibility structure and then al...

摘要：Crowdshipping, a rapidly growing approach in Last-Mile Delivery (LMD), relies on independent crowdworkers to fulfill delivery orders. Building a sustainable network of crowdshippers is crucial for the long-term success of such systems, as participation is primarily driven by fair compensation. This is especially important for workers who rely on crowdwork as their main source of income, making equitable pay not just a matter of fairness but of financial well-being. In this study, we address se...

摘要：Firms are exposed to varying levels of supply chain risk and engage in efforts to resolve such risk. This paper examines how disclosures of supply chain risk and resolution during earnings calls affect firms' stock returns. Using natural language processing, we develop measures of supply chain risk and resolution from quarterly earnings call transcripts for a total of 129,981 firm-quarter observations between 2008 and 2019. We find that higher levels of supply chain risk are associated with lo...

摘要：This study explores the effects of competition on fair trade operations. Specifically, as a benchmark, we first consider a model with a single fair trade organization (FTO), that is, a monopoly FTO. We then extend the analysis to a setting with two competing FTOs, that is, duopoly FTOs. Although both FTOs share the common goal of alleviating farmers poverty, they adopt contrasting strategies: One FTO seeks to lower the barriers to fair trade, aiming to mainstream it, while the other maintains ...

摘要：Newborn screening (NBS) plays a key role in detecting life-threatening genetic disorders, with cystic fibrosis (CF) being a prominent example. Having CF requires both copies of the CFTR gene (one inherited from each parent) to be pathogenic variants. With over 1,000 CF-causing variant types, a genetic test that can detect enough variant types for sufficient screening accuracy is expensive and capacity-constrained. Consequently, in the US, the first tier of testing uses an inexpensive biochemic...

摘要：Training is an important business in the service sector. Usually, a training program involves multiple sessions and each session contains multiple activities. Although it is essential for customers to participate in all training sessions and activities, many customers fail to complete the program because the training experience is too stressful. Given the importance of customer retention in the training programs, we investigate the modeling and optimization of the retention-oriented training p...

摘要：The attended home healthcare (AHH) industry is experiencing rapid growth due to the rising demand from an aging population and the potential benefits of alleviating pressures on traditional healthcare resources. However, ensuring timely one-on-one AHH services for homebound patients remains a challenge because of cascading delays arising from uncertainties in travel and service times. To address this issue in last-mile homecare delivery, we develop a systematic cascading delay mitigation strat...

摘要：A transaction fee is fundamental in maintaining the stability and decentralization of a permissionless blockchain, the infrastructure underlying major cryptocurrency networks such as Ethereum and Bitcoin. This fee, set and paid by users when initiating each transaction, aggregates to over $24 million daily on Ethereum, imposing a nontrivial barrier to wider adoption. What is worse is that it is disproportionately borne by small users. Like Bitcoin, Ethereum started with a name-your-own-price s...

摘要：In this study, we investigate the impact of organizational structures on supply chain participants, specifically when retailers establish strategic inventory in a competitive environment. We build a two-period supply chain model in which two retailers procure from a common supplier, compete in multiple markets, and can carry inventory from the first period to the second. We characterize the optimal strategies for firms under three scenarios, depending on whether each retailer operates under ce...

摘要：The proliferation of fake news, more recently multimodal fake news, poses a significant threat to individuals, organizations, and society. While online social media platforms have employed automated methods to combat fake news, they face two notable challenges: the scarcity of labeled data and the diversity of news domains. To enhance the effectiveness and efficiency of online platforms in mitigating the spread of fake news, this study proposes MT-GPD (multimodal deep transfer learning with ga...
