摘要:Home care provides personalized medical care and social support to patients within their own homes. Our work proposes a dynamic scheduling framework to assist in the assignment of health practitioners (HPs) to patients who arrive stochastically over time and are heterogeneous with respect to their health requirements, service duration, and region of residence. We model the decision of which patients to assign to HPs as a discrete-time, rolling-horizon, infinite-stage Markov decision process. D...

摘要:E-commerce platforms struggle to create and maintain high-quality reputation systems. One promising option is purchase verification, which confirms that the user reviewing a product purchased the product from the platform. Previous works comparing platforms that require purchase verification with platforms that do not offer purchase verification found that review manipulation is easier in the latter. But what happens in platforms where purchase verification is optional? In such platforms, ther...

摘要:George Dantzig introduced the world to the power of optimization, creating trillions of dollars of value and saving countless years of life across the globe. Linear programs and Dantzig's many other contributions to optimization have driven enormous increases in productivity throughout the global economy. Linear programming has also become a vital tool in advancing artificial intelligence and machine learning.

摘要:We study a vacation queueing model where an arriving customer, upon finding the server to be on vacation, is offered an opportunity to pay a fee to instantaneously end the server's vacation, which is referred to as pay-to-activate-service (PTAS). If no one utilizes PTAS, the service will automatically resume when the system's workload reaches a critical level. We investigate customers' equilibrium strategies: (i) joining or balking and (ii) if joining, accepting PTAS or rejecting PTAS, in resp...

摘要:Warfare afflicts millions and creates unparalleled operational challenges in the developing world. With data from war-torn Colombia, I examine the effects of civil war on firms' total factor productivity (TFP) using propensity score and conflict hotspot models. I find that warfare increases TFP in service firms, such as public administration and defense, by up to 12.68%, whereas it decreases TFP in manufacturing and other nonservice companies by up to 3.64% a year after a violent episode occur...

摘要:We study how customer satisfaction affects platforms' advertising competition and their equilibrium market shares and profits. Consider a market with multiple competing (online) platforms, all of which decide advertising outlay to maximize their own average profit. A customer chooses which platform to visit depending on her experience of the last purchase and on the platforms' advertising outlays. After purchasing from a platform, with certain probability (satisfaction probability), the custom...

摘要:Internet of Things (IoT) technology utilizes sensors and other internet-enabled devices to collect and share data. It is widely regarded as a disruptive technology that brings tremendous opportunities to supply chain members. This study uses a game-theoretical model to study an e-commerce setting in which an online platform provides IoT infrastructure and a manufacturer sells its products on the platform. Our work examines the interaction among the manufacturer's IoT investment decision, the p...

摘要:We study consumers' valuation of status signals by estimating their willingness to pay for a luxury item with a quiet vs. a prominent logo. We collected data from two online markets on sales of two luxury handbags that differ principally in the prominence of their logo. We use these data to estimate the premium in consumers' willingness to pay for the handbag with the quiet logo, and to estimate how the condition of the handbag affects that premium. We find consumers are willing to pay a sizea...

摘要:Competing and coexisting policies (CACPs) may arise from the incompatibility of incentives, standards, and regulatory models between a local state and a federal government, or between two government jurisdictions across which supply networks operate. Traditional studies of supply chain dynamics typically explore the impact of policy regimens as standalone instruments. This study explores how the interplay between CACP regimens can affect the supply dynamics between producers, customers, and th...

摘要:Failing to sell fresh produce before expiration not only hurts the bottom line of grocery retailers, but also leads to food waste. This work combines dynamic pricing and information disclosure to help retailers to effectively sell fresh produce and promote sustainability. We focus on a quality-based pricing strategy and whether retailers should disclose information on food quality to customers. We consider a model where a monopolistic retailer sells fresh produce to customers who have differen...
