摘要:The financial industry is plagued with account-based fraudulent transactions in which perpetrators surreptitiously siphon away money from customer accounts. To address this recurrent problem, service operations teams at financial institutions (e.g., the fraud detection and mitigation teams) spend millions yearly identifying perpetrators, attributing blame, and averting customer churn. However, in the vast majority of cases, the service operations teams cannot trace fraudulent transactions back...

摘要:This study examines the relation between political uncertainty arising from state-level election cycles and the timing of employee dismissal and plant closure notices filed by US firms under the Worker Adjustment and Retraining Notification (WARN) Act of 1988 (hereafter, WARN notices). We appeal to a real options framework to predict that firms delay layoff decisions and the issuance of WARN notices until the resolution of political uncertainty. Using establishment-level data on layoffs disclo...

摘要:We investigate an ambulatory care scheduling problem derived from a real case in Ontario, Canada that offers multi-appointment, multi-class, multi-priority treatments in geographically distributed campuses with multiple resources. We consider a dynamic setting with uncertain patient arrival and use of the emergency department. This problem is formulated as an infinite-horizon Markov decision process model. Since we cannot solve large-sized instances via conventional approaches, we hybridize th...

摘要:Modern decision-support applications build on planning parameters such as lead time, price, yield, etc., which are maintained as master data. The accuracy of master data significantly influences the viability of such applications. However, the maintenance of master data is considered a tedious and error-prone task. In this study, we explore the effectiveness of machine learning techniques to improve the accuracy of plan lead times. We apply both unsupervised and supervised learning methods for...

摘要:We explore retail supply chains in emerging markets in which a manufacturer can reach consumers by selling its product through very small independent stores (nanostores) and/or through a supermarket. Nanostores offer consumers the advantage of proximity, but supermarkets offer the advantage of bulk buying. We explore the competition between the supermarket and nanostores and examine the manufacturer's role in shaping the retail market structure for its product through wholesale price contracts...

摘要:This study examines the relationship between major customer concentration and supplier firms' adoption of blockchain. Using a sample of 9,745 Chinese firm-year observations spanning 2018-2021, we find that the likelihood of suppliers' blockchain technology adoption in supply chain management is negatively associated with major customer concentration. The negative relation is reduced when supplier firms possess greater bargaining power and demonstrate governance mechanisms against information l...

摘要:This paper presents a decision support system used by an agricultural cooperative in the Indian states of Andhra Pradesh and Telangana to optimize the purchase, blending, sale, and storage of groundnuts for maximum profit. The cooperative buys raw groundnuts (input commodity) from member farmers and processes them into multiple grades of groundnut seeds (output commodity). These may then be blended to create intermediate grades to exploit arbitrage opportunities. The cooperative sells part of ...

摘要:Social advertising platforms and search engines employ the so-called quality score to favor certain advertisers in ad auctions. These scores typically consider several factors including ad relevance, click-through rate (CTR), and landing page quality. While quality scores are often justified as a mechanism to enhance ad rank and reduce cost per click for high-quality ads, this study examines their broader role in incentivizing advertisers with varying investment costs to improve landing page q...

摘要:We conduct a descriptive analysis of the performance of disciplines, journals, authors, and universities based on the number of publications in 50 business and economics journals represented in the Financial Times list (FT 50) from 2008 to 2022 using data from the Web of Science. We analyze more than 55,000 papers published by more than 54,000 unique authors during this period to document four sets of findings. First, our analysis suggests that Operations Management and Multidisciplinary areas...

摘要:Purchasing new experience products or services often involves significant quality uncertainty for both consumers and firms. Social learning through online reviews helps reduce this uncertainty but exacerbates strategic waiting, as consumers delay purchases to gain more information. This paper examines the impact of social learning on firms' pricing policies in the presence of strategic consumers under two widely adopted schemes: Contingent pricing and price guarantee. We find that while social...
