摘要:Markov decision processes (MDPs) provide a powerful framework for analyzing dynamic decision making. However, their applications are significantly hindered by the difficulty of obtaining solutions. In this study, we introduce reducible MDPs whose exact solutions can be obtained by solving simpler MDPs, termed the coordinate MDPs. The value function and an optimal policy of a reducible MDP are linear functions of those of the associated coordinate MDP. Because the coordinate MDP does not involv...

摘要:Payment management is an operations management challenge in online peer-to-peer (P2P) lending. It is critical to control the cost of debt collection incurred in late repayments and defaults. We study whether and how a platform can leverage on borrowers' social connections and use automatic social notifications in regulating repayment behavior. In collaboration with a large online P2P lending platform, we conduct a randomized field experiment to investigate the effect of social notifications ta...

摘要:Business users (suppliers) of information technology (IT) equipment often contract with third party remanufacturers (3PRs) for the end-of-use disposition of their used electronic equipment. Our goal in this research is to develop a model to analyze contracts consisting of an upfront payment (t) and a revenue share (r) between a supplier and 3PR, study their impact on disposition decisions, and explore the impact of 3PR risk-aversion and quality uncertainty on optimum contracts. We model a Stac...

摘要:This study examines innovation tournaments in which an organizer seeks solutions to an innovation-related problem from a number of agents. Agents exert effort to improve their solutions but face uncertainty about their solution performance. The organizer is interested in obtaining multiple solutions-agents whose solutions contribute to the organizer's utility are called contributors. Motivated by mixed policies observed in practice, where some tournaments are open and others restrict entry, we...

摘要:Throughout its history, the industrial engineering/operations management (IE/OM) field has relied heavily on axiomatic models and empirical studies of individual systems. But, unlike other engineering and management disciplines, it lacks a clear foundation in a descriptive science. Exceptional results like the famous bullwhip effect paper by Lee et al. (1997) hint at the powerful potential for a descriptive science of operations. But the very fact that such works are exceptional suggests that ...

摘要:We investigate the impact of health information exchange (HIE) use at the visit level on patient outcomes, such as future visit behavior and the number of procedures performed on the patient, and how the effects differ across patient and visit characteristics, for example, whether a patient has chronic conditions and whether a visit involves a hospital switch. Timely sharing of patient information is expected to decrease the fragmentation of care and improve decision-making, diagnoses, and car...

摘要:Buyers are increasingly pressured to ensure sustainability of their suppliers, but they are also under pressure for low-cost procurement. To make a more informed procurement decision, a buyer can choose to invest in sustainability assessments, and select a supplier based on their price bids and cost markup terms informed by the sustainability assessments. However, sustainability assessments are costly, and whether to use them is at the discretion of the buyer. Hence, the buyer can instead choo...

摘要:A firm's product-cost information is increasingly transparent to consumers as the firm itself or third parties publish such information, which reduces consumers' uncertainty for the product's cost. Using a dynamic model of firm pricing with forward-looking consumer choices, this study assesses how cost transparency affects the firm's intertemporal price discrimination and profit, as well as the consumers' strategic waiting decisions and surplus.Ceteris paribus, if consumers believe a durable p...

摘要:In this study, we consider the problem of estimating demand functions using historical sales data. In particular, we study how using aggregate data may result in bias in such estimations. We consider a log-log demand model, and two ways of how the price in the aggregate data is calculated, simple average price or weighted average price. We study whether there exists estimation bias in each of the two cases as well as the direction of the bias. We show that in general, the correlation between a...

摘要:We investigate the trade-off between acquisition and retention efforts when customers are sensitive to the quality of service they receive, that is, whether they get timely access to a company's resources when requested. We model the problem as a multi-class queueing network with new and returning customers, time-dependent arrivals, and abandonment. We derive its fluid approximation; a system of ordinary linear differential equations with continuous, piecewise smooth, right-hand sides. Based o...
