摘要：Problem definition: The adoption of online services, such as telemedicine, has increased rapidly over the last few years. To better manage online services and effectively integrate them with in-person services, we need to better understand customer behaviors under the two service modalities. Utilizing data from two large internal medicine outpatient clinics, we take an empirical approach to study service incompletion, which can be because of either patient no-show or leaving without being seen...

摘要：Problem definition: In the user-generated content (UGC) business model, the platform provides income for the creators, the creators provide content for the viewers, and the viewers provide advertising revenue for the platform, forming a relationship triangle. We set out to study a UGC platform's optimal dynamic operational policies in its different stages and the impact of various constraints and innovations. Methodology/results: We adopt a hybrid of the Bass diffusion model and the replicator...

摘要：Problem definition: Micromobility systems (bike-sharing or scooter-sharing) have been widely adopted across the globe as a sustainable mode of urban transportation. To efficiently plan, operate, and monitor such systems, it is crucial to understand the underlying rider demand-where riders come from and the rates of arrivals into the service area. They serve as key inputs for downstream decisions, including capacity planning, location optimization, and rebalancing. Estimating rider demand is no...

摘要：Problem definition: Motivated by online dating platforms, we study the problem of selecting which subset of profiles to display to each user in each period. Users observe the profiles set by the platform and decide which of them to like, and a match occurs if and only if two users mutually like each other, potentially across different periods. The platform aims to maximize the expected number of matches produced over the entire time horizon, and users' behavior-captured by their like probabili...

摘要：Problem definition: Last-mile delivery is one of the most challenging and costly facets of the supply chain. Using data from Rwandan public hospitals that transfuse blood, we examine whether and the extent to which the adoption of a technological innovation- delivery drones-for the last-mile delivery of blood products impacts the way hospitals manage the inventory of these products and the downstream health outcomes for patients. Methodology/results: To estimate causal effects, we exploit the ...

摘要：Problem definition: The internet facilitates sex trafficking through adult service websites (ASWs) that host online advertisements for sexual services (sex ads). Since the closure of the popular site Backpage.com, the ecosystem of ASWs has expanded to include multiple competing sites that are hosted outside U.S. jurisdiction. Gaining intelligence for counter-trafficking efforts requires collecting, linking, and cleaning the data from multiple sites. However, high ad volumes, disparate data typ...

摘要：Problem definition: Mass trauma events (MTEs) present significant operational challenges. Affected populations require both immediate and prolonged mental health support, complicating response efforts. Posttraumatic stress disorder (PTSD) can have lasting effects and imposes a substantial economic burden, making early intervention critical to improving outcomes. The October 7, 2023, terror attack in southern Israel caused widespread trauma. Survivors, responders, and many others were exposed t...

摘要：Problem definition: An online retailer selling a perishable product can issue inventories of different remaining lifetimes in its preferred sequence. This creates a tradeoff between customer satisfaction and outdating costs since customers want freshness, whereas the retailer desires units be sold within their lifetime. We study this trade-off by considering a joint replenishment and issuance policy for a perishable product with a general lifetime. Methodology/results: We develop a periodic re...

摘要：Problem definition: This paper investigates the effectiveness of emission permits policies with varying levels of temporal flexibility, including different compliance periods and the allowance/prohibition of intertemporal banking and borrowing. We also explore advanced policy designs aimed at improving social welfare. Methodology/results: Our analysis reveals that extreme policies, such as fully flexible or fully nonflexible permits, are generally suboptimal from a welfare perspective. Restric...

摘要：Problem definition: An emerging financial innovation enabled by technological advancements in agricultural supply chains is the ability to tip the farmers. This mechanism empowers socially conscious consumers to identify and support the individual farmers of their products by sending them direct payments, or tips. We shed light on the implications of tipping on different market participants. Methodology/results: We construct a game-theoretic model that captures the interactions between a mass ...
