摘要：Online platforms are experimenting with interventions such as content screening to moderate the effects of fake, biased, and incensing content. Yet, online platforms face an operational challenge in implementing machine learning algorithms for managing online content due to the labeling problem, where labeled data used for model training are limited and costly to obtain. To address this issue, we propose a domain adaptive transfer learning via adversarial training approach to augment fake cont...

摘要：How do firms respond after being exposed to a low-probability, high-consequence (lp-hc) disruption event? This study examines inventory and flexibility patterns in manufacturing firms in the years following an lp-hc event, the Great East Japan Earthquake of 2011. We find patterns suggesting that most firms exposed to the event began to increase their raw material inventories (RAW) over the longer term and increased their volume flexibility for a shorter period. Furthermore, we found that firms...

摘要：Many individuals have strong preferences regarding COVID-19 vaccines and would like to choose the vaccine they get. This practice, known as vaccine shopping, presents unique challenges to timely vaccine rollout: On the one hand, people may not get vaccinated if they are unable to receive their preferred vaccine, and on the other hand, a policy maker is inclined to distribute vaccines in a brand agnostic fashion to avoid wastage. We study whether a policy maker should allow individuals to choos...

摘要：We study inventory control involving lost sales and hence censored demand. In a long-run average framework, the demand distribution is largely unknown. As long as the stationary inventory costs are strictly convex to the extent that the second lost item costs strictly more than the first one, the regret would be Omega(T-2/3). Our discrete-item setting has rendered the presence or absence of strong censoring indicators or equivalently, being knowledgeable or ignorant of one more demand request ...

摘要：Patient-reported outcomes (PROs) play an increasingly important role in medical decision making. Yet, patients whose objectives differ from their physician's may strategically report symptoms to alter treatment decisions. For example, athletes may underreport symptoms to expedite return-to-play (RTP) from sports-related concussion (SRC). Thus, clinicians must implement treatment policies that mitigate the Price of Naivete, that is, the reduction in health outcomes due to naively believing stra...

摘要：Motivated by the booming online grocery market and the extensive use of contingent free-shipping (CFS) policies in the e-grocery industry, we investigate the optimal CFS and pricing decisions for online grocers. Under a CFS policy, consumers enjoy free shipping for orders exceeding a certain threshold value; otherwise, they are charged a flat fee for orders below this threshold. We adopt a utility-based model to capture consumers' behavior of purchasing additional items to qualify for free shi...

摘要：Motivated by the challenge of allocating scarce resources from the federal government to different states during the COVID-19 pandemic, this paper studies optimal schemes for allocating scarce resources to agents with private demand information under different favoritism structures. Through an investigation of a mechanism design model that aims to induce agents to report their demands truthfully, we find the following results. First, when the principal purely cares about social welfare and whe...

摘要：We study an optimal matching problem in the context of dual-donor organ exchange, where a portion of two living donors' organs are transplanted to a single patient. This dual-donor transplant technique is becoming more widespread for lung and liver transplants. However, multiple medical compatibility criteria pose a serious challenge for matching a patient with two compatible donors. In the United States and many other countries, laws prohibit commercial (for-profit) deals for human organs, so...

摘要：The choice of market mechanism is key to success for any online marketplace. In recent years, as peer-to-peer (P2P) lending has seen phenomenal growth, leading P2P lending platforms have used various market mechanisms and, in some cases, even switched from one mechanism to another, chasing higher market share and overall growth. While Prosper.com, a leading P2P lending platform, has switched from the auction lending model to a fixed price lending model, recent studies show that overall social ...

摘要：We consider a car rental network revenue management (RM) problem, accounting for the key operational characteristics of car rental services such as the varying length of rentals and mobility of inventories, which imply the intertemporal and spatial correlations of rental demands for inventories across different locations and days. The problem is formulated as an infinite-horizon cyclic stochastic dynamic program to account for the time-varying and cyclic nature of car rental businesses. To tac...
