  摘要：In the event of a virus outbreak such as Covid-19, testing is key. However, long waiting lines at testing facilities often discourage individuals from getting tested. This paper utilizes queueing-game-theoretic models to study how testing facilities should set scheduling and pricing policies to incentivize individuals to test, with the goal to identify the most cases of infection. Our findings are as follows. First, under the first-in-first-out discipline (FIFO), the common practice of making ...
• Finite-horizon approximate linear programs for capacity allocation over a rolling horizon AI翻译

  摘要：Approximate linear programs (ALPs) have been used extensively to approximately solve stochastic dynamic programs that suffer from the well-known curse of dimensionality. Due to canonical results establishing the optimality of stationary value functions and policies for infinite-horizon dynamic programs, the literature has largely focused on approximation architectures that are stationary over time. In a departure from this literature, we apply a nonstationary approximation architecture to an i...
• Impact of universal healthcare on patient choice and quality of care AI翻译

  摘要：This paper examines the role of universal healthcare on patient choice and quality of care. Lack of health insurance is a leading contributor to emergency department (ED) visits from the uninsured. Using a natural experiment from Massachusetts, we follow previously uninsured individuals over time-both before and after the implementation of universal healthcare-to study the effects of insurance availability on their healthcare seeking behavior. We find that the availability of health insurance ...

  摘要：This study posits that executive attention can significantly influence the impacts of customer-facing electronic business (e-Business) systems on firm performance. Using the exploration-exploitation perspective (EEP) as an overarching theoretical framework, and the theoretical lens of attention-based view (ABV), we develop an integrated model to provide insights into the impacts of customer-facing e-Business systems on firm performance. We categorize the capabilities of customer-facing e-Busin...
• To Predict or Not to Predict: The Case of the Emergency Department AI翻译

  摘要：Coupling healthcare datasets with advanced statistical methods has the potential to improve the efficiency and quality of healthcare dramatically. However, data used for predictive decision making in healthcare delivery has significant variable costs. We offer a novel and generalizable framework that helps reduce the costs associated with the use of data for healthcare analytics while maintaining high predictive accuracy. We utilize this approach in the emergency department (ED) context and sp...
• Admission Control Game with Capacity Borrowing AI翻译
  作者：Wang, Tianxiang; Yu, Peiwen; Hu, Jianqiang

  摘要：We study a decentralized admission control problem with capacity borrowing. In this problem, the admission decision is made by each server who is assigned dedicated capacity. However, a server can borrow capacity from other servers if his dedicated capacity is exhausted. The borrower compensates the lender by a payment equal to the borrowing cost. Hence, the servers share their capacities via borrowing, but they also compete against each other for their pooled capacities. We formulate this pro...

  摘要：Universal health coverage (UHC) is an integral part of the United Nations sustainable development goals. The private sector plays a prominent role in achieving UHC, being the primary source of essential medicines for many people. However, many private healthcare facilities in low- and middle-income countries (LMICs) have insufficient stocks of essential medicines. Simultaneously, these same facilities carry excessive quantities of other drugs, leading to obsolescence. This suggests poor invent...
• Locating facilities under competition and market expansion: Formulation, optimization, and implications AI翻译

  摘要：As the ongoing battle between brick-and-mortar stores and e-commerce shops escalates, managers of the former are becoming more cautious regarding their strategic store site selection and decoration decisions, particularly if foreseeable competition from rival companies exists. This paper investigates a bilevel competitive facility location (BCFL) problem, where two companies, a leader and a follower, plan to enter a market sequentially. Each company has a budget to open and design facilities. ...
• A theory-driven machine learning system for financial disinformation detection AI翻译

  摘要：Maliciously false information (disinformation) can influence people's beliefs and behaviors with significant social and economic implications. In this study, we examine news articles on crowd-sourced digital platforms for financial markets. Assembling a unique dataset of financial news articles that were investigated and prosecuted by the Securities and Exchange Commission, along with the propagation data of such articles on digital platforms and the financial performance data of the focal fir...

  摘要：Online word-of-mouth studies generally assume that a product's average rating is the primary force shaping consumers' purchase decisions and driving sales. Similarly, practitioners place more emphasis on average ratings by displaying them at more salient places than individual reviews. In contrast, emerging evidence suggests that individual reviews also affect the decision-making of those consumers who consult both kinds of information. However, because average ratings and individual reviews a...
