摘要：Problem definition: Equitable vaccine distribution is paramount to containing global disease outbreaks. An important pathway to achieve this goal is pooled vaccine procurement through global coalitions, exemplified by the COVID-19 Vaccine Global Access (COVAX) initiative, which was implemented based on equitable, centrally managed vaccine allocation, affordable prices, and subsidies to fund lower-income economies. However, the limited participation of high-income countries-which chose to purch...

摘要：Problem definition: Digital content manufacturers and retailers (platforms) frequently encounter the issue of digital piracy. To deter the consumption of pirated content, manufacturers enhance the quality of genuine products, whereas retailers often exert antipiracy efforts. Such efforts best work in coordination, which is achieved through financial incentives via two widely used contracts: wholesale and agency. In the absence of piracy, two results are well established: (a) an increase in the...

摘要：Problem definition: Online marketplaces have revolutionized online sales by creating platforms that connect millions of buyers and sellers. Although the presence of numerous third-party sellers attracts customers, it also results in a proliferation of listings for each product, making it difficult for customers to choose between the available options. To address this issue, online marketplaces employ algorithmic tools to curate and present different product listings to customers. Although tool...

摘要：Problem definition: We study innovative capacity-planning strategies for service systems that encounter significant challenges in maintaining service quality because of worker shortages, a prevalent and growing issue across healthcare, retail, customer service, and other labor-intensive sectors. Methodology/results: Using a stylized queueing model representing a centralized service system, we propose a multistage staffing strategy utilizing capacities of various flexibility. Accounting for dem...

摘要：Problem definition: The rise of digital channels has led to significant media market transformations. This paper studies whether and how digitization, sparked by the launch of Amazon Kindle in late 2007, affected print book sales. Methodology/results: To estimate the impact, we exploit the quasiexperimental variation in the popularity of digital books across different genres or subgenres. We employ difference-in-differences and other identification strategies, and we use print sales data on a ...

摘要：Problem definition: We study the impact of an airline's route-level decisions on the efficiency and resilience of its operations. Methodology/results: Our study uses a proprietary passenger-level data set provided by Southwest Airlines and takes advantage of a regulatory change, the Wright Amendment repeal. The Wright Amendment restricted nonstop service between Dallas Love Field Airport (DAL) and most major destinations. Its repeal led to significant changes in Southwest's service offerings a...

摘要：Problem definition: Zoonotic viruses that jump from animals to humans, like avian influenza or severe acute respiratory syndrome, have caused major pandemics in recent decades. Many of these pandemics originated in China, a major supplier and consumer in the global food supply chain, and in other low-and middle-income countries. Interestingly, these outbreaks have been linked to live animal markets, even when the surrounding farms supplying markets had very low infection prevalence. This sugge...

摘要：Problem definition: Emergency medical services (EMS) in many low- and middleincome countries utilize decentralized platforms coordinating independent ambulance providers. However, significant operational challenges arise from uncertainty in provider time availability and unpredictable idle locations. These uncertainties hinder reliable service coverage and negatively impact patient outcomes. Using data from our East-African partner Rescue.co regarding the operations of their emergency platform...

摘要：Problem definition: Faced with the growing need to improve access to care, hospitals have been operating at capacity in recent times. We argue, however, that the pursuit of utilization beyond a threshold might come at a cost. We propose that there exists a zone of efficiency within which the costs of care reach the minimum and the pursuit of utilization outside of this zone may be counterproductive. Our second objective is to explicitly incorporate the complexity of care requirements in unders...
