摘要：Although there are both process-related and human-related grounds for systematic performance variations across days of the week, such a phenomenon has not caught the attention of information systems or operations management scholars. Using transaction-level data from the U.S. Government's General Services Administration, we study three layers of effects: the Monday Effect, the Technology Effect, and the Product Effect. First, we assess whether performance varies across days of the week in supp...

摘要：Question-and-answer (Q&A) forums are gaining popularity as a user-engagement tool to drive traffic on multiservice portals. In a platform market model, demand-side users seek answers from supply-side users because such answers can indicate value offered, reduce buyer uncertainty, and offer social proof. Analyzing user-generated content on the Q&A forum of a prominent healthcare portal, we find that the introduction of doctors' responses has a significant causal impact on demand-side user perce...

摘要：This paper examines the dynamic consumption behavior of individual mobile data users by employing a unique data set on individual-level daily usage over multiple months. Whether and which individual mobile data users are forward looking by dynamically balancing present and future usage and how to design profitable promotions targeting these users are questions of both academic and managerial interest. By developing a dynamic structural model and formally proving its theoretical properties, we ...

摘要：We develop efficient computational strategies for the inventory liquidation problem, which is characterized by a retailer disposing of a fixed amount of inventory over a period of time. Liquidating end-of-cycle products optimally represents a challenging problem owing to its inherent stochasticity. The growing scale of liquidation problems further increases the need for solutions that are revenue- and time-efficient. We propose to address the inventory liquidation problem by deriving determini...

摘要：Managerial responses to online customer reviews not only affect customers who receive the responses but may also influence subsequent customers who observe the responses. This externality arises because of the public nature of online interactions. However, prior studies were mainly in offline settings where such externality rarely exists. In this study, we assess the magnitude of such externality. Using a difference-in-difference-in-differences framework and matched hotels across two large tra...

摘要：Free product sampling has increasingly become a popular promotional strategy and served as a new mechanism of product review generation in e-commerce. We empirically analyze how a product's engagement in free product sampling affects the product's review rating, and we also examine important contingent factors of product pricing and product popularity. Using a rich data set from Taobao. com and multiple identification strategies and estimation methods, we find that engaging in free product sam...

摘要：Fraud, waste, and abuse are significant problems in major industries such as healthcare, particularly when third-party payers such as Medicare are involved. Auditors looking for fraudulent activities use scoring models to select practitioners or claims that are likely to be fraudulent. In addition to the direct benefits of the audit effect, which evokes a response by auditing fraudulent individuals, the sentinel effect provides second-order benefits. Yet current auditing algorithms do not take...

摘要：We study the efficiency of bilateral liability-based contracts in managed security services (MSSs). We model MSS as a collaborative service with the protection quality shaped by the contribution of both the service provider and the client. We adopt the negligence concept from the legal profession to design two novel contracts: threshold-based liability contract and variable liability contract. We find that they can achieve the first best outcome when postbreach effort verification is feasible....

摘要：We investigate the long-term impact of competing against superstars in crowdsourcing contests. Using a unique 50-month longitudinal panel data set on 1677 software design crowdsourcing contests, we illustrate a learning effect where participants are able to improve their skills (learn) more when competing against a superstar than otherwise. We show that an individual's probability of winning in subsequent contests increases significantly more after she has participated in a contest with a supe...

摘要：Although Fogg's ideas of persuasive technologies are widely accepted, few attempts have been made to test his ideas, particularly in a team context. In this article, we (1) theoretically extend Fogg's ideas by identifying contexts in which virtual teams are more likely to use persuasive technologies; (2) empirically measure technology visualness, a factor that likely makes technologies more or less persuasive; and (3) assess the association between the use of persuasive technologies, judgment ...
