摘要:Problem definition: This study examines self-attribution tendencies and their associated outcomes in operations management (OM) performance evaluation in which managers are not always objective when giving credit to outcomes. They may attribute strong performance to internal factors (internal credit), assigning poor performance to external factors (external blame). Methodology/results: Large language models (LLMs) based on LLaMA-3.1-8B-Instruct are fine-tuned to analyze earnings call question-...

摘要:Problem definition: Following recent legislation, private insurers participating in Medicare Advantage (MA) are allowed to expand their set of supplementary services to include benefits that are not primarily health related. This policy is meant to lead to lower costs and better care, but questions have been raised about how this affects the incentives of private insurers. We investigate the implications of the policy for MA offerings, beneficiary enrollment, and social welfare. Methodology/re...

摘要:Problem definition: We study optimal integrated inventory and pricing decisions for substitutable products over a finite planning horizon with full backlogging and nonstationary costs and demands. The objective is to maximize the total expected discounted profit. Methodology/results: We present a unified demand model that encompasses many commonly used models in the literature. We show that the dynamic optimization problem is jointly concave in inventory and market-share vectors. This enables ...

摘要:Problem definition: Online allocation problems with resource constraints have a rich history in operations management. In this paper, we introduce the regularized online allocation problem, a variant that includes a nonlinear regularizer acting on the total resource consumption. In this problem, requests repeatedly arrive over time, and for each request, a decision-maker needs to take an action that generates a reward and consumes resources. The objective is to simultaneously maximize additive...

摘要:Problem definition: During pandemics, policymakers must make critical decisions about public health interventions and allocations of scarce resources in response to rapidly evolving diseases under high levels of uncertainty. Epidemiological models, such as the Susceptible-Exposed-Infectious-Recovered-type (SEIR-type) compartmental model, are indispensable tools for predicting how a pandemic may spread over time and how different public health interventions could affect the outcome. Based on su...

摘要:Problem definition: Although a centralized firm selling durable products benefits from committing to future prices, it remains unclear whether this conclusion extends to a decentralized supply chain where a manufacturer distributes durable products through a retailer. Further, previous research on commitments in decentralized supply chains is sparse and assumes exogenous commitments. To address this gap, we examine the implications of commitment decisions in a supply chain where a manufacturer...

摘要:Problem definition: We investigate a seller's optimal advertising strategy targeting customers who interact with the seller over time. We model each customer's engagement by a continuous-time (hidden) Markov chain with two states: active and inactive. While in the active state, customers make purchases according to a Poisson process; in contrast, customers in the inactive state make no purchases. The seller can use advertisements to activate customers and the activation probability may be affe...

摘要:Problem definition: Trade credit is a common mechanism for financing retail inventories. A supplier who offers trade credit may not observe sales revenue and verification is costly. When a retailer offers to pay less than the full loan amount, the supplier may either accept the offered amount or initiate verification. We investigate the impact of costly sales revenue verification on the equilibrium wholesale price and loan limit, with the goal of determining whether the supplier's profit is gr...

摘要:Problem definition: We examine how market and economic factors influence the occurrence of forced labor in supply chains and how buying companies can develop optimal contracts to prevent forced labor in the presence of information asymmetry between the buyer and the agent. Methodology/results: We develop a game-theoretic model of a labor supply chain comprising a socially aware buyer and a profit-maximizing labor agent. Our equilibrium analysis shows that the audit cost affects the extent to w...

摘要:Problem definition: Family engagement (FE) is an ongoing partnership between health professionals and patients' families to enhance healthcare quality, safety, and delivery. Although FE is increasingly considered an essential component of patient-centered care, its importance in influencing healthcare delivery outcomes is unclear. This study examines the impact of FE on patient care outcomes (PCOs)-specifically, patient satisfaction (PS) and readmission (Readm)-in the context of varying severi...
