摘要：Providing broadband to schools can be an effective way to foster household Internet adoption in neighboring areas. On the one hand, the infrastructure put into place to meet schools' needs can also serve households. On the other hand, students get acquainted with the Internet at school and signal its usefulness to adults at home who, consequently, can be more likely to adopt it. In this paper, we model the roles that broadband use at school and Internet adoption in neighboring households play ...

摘要：Comparative payment schemes and tournament-style promotion mechanisms are pervasive in the workplace. We test experimentally whether they have a negative impact on people's willingness to cooperate. Participants first perform in a simple task and then participate in a public goods game. The payment scheme for the task varies across treatment groups. Compared with a piece-rate scheme, individuals in a winner-takes-all competition are significantly less cooperative in the public goods game. A lo...

摘要：Firms tracking consumer purchase information often use behavior-based pricing (BBP), i.e., price discriminate between consumers based on preferences revealed from purchase histories. However, behavioral research has shown that such pricing practices can lead to perceptions of unfairness when consumers are charged a higher price than other consumers for the same product. This paper studies the impact of consumers' fairness concerns on firms' behavior-based pricing strategy, profits, consumer su...

摘要：This study provides novel evidence that cash-flow news quantitatively explains the investment effect in the cross section of stock returns. The negative return predictability of asset growth, investment growth, and accruals is evident only through the cash-flow news component of returns. The cash-flow news returns associated with investment-sorted portfolios exhibit a reversal from the preformation period to the postformation period. Such a return reversal is in line with reversals in firm fun...

摘要：Open content production platforms typically allow users to gradually create content and react to previous contributions. Using detailed edit-level data across a large number of Wikipedia articles, we investigate how past edits shape current editing activity. We find that cumulative past contributions, embodied by the current article length, lead to significantly more editing activity, while controlling for a host of factors such as popularity of the topic and platform-level growth trends. The ...

摘要：Resource assignment problems occur in a vast variety of applications, from scheduling problems over image recognition to communication networks. Often these problems can be modeled by a maximum weight matching problem in (bipartite) graphs or generalizations thereof, and efficient and practical algorithms are known for these problems. Although in some of the applications an assignment of the resources may be needed only once, in many of these applications, the assignment has to be computed mor...

摘要：To better understand two large consumer segments, the boomers and the echo-boomers, we examine whether and why experts and novices from these two segments rely on attribute versus benefit information in product evaluations. In four studies, we show that expertise affects younger consumers, such that younger novices evaluate products more favorably when the descriptions feature benefit information, whereas younger experts evaluate products more favorably when the descriptions feature attribute ...

摘要：Risk pooling has been studied extensively in the operations management literature as the basic driver behind strategies such as transshipment, manufacturing flexibility, component commonality, and drop shipping. This paper explores the benefit of risk pooling in the context of inventory management using the canonical model first studied in Eppen [Eppen GD (1979) Effects of centralization on expected costs in a multi-location newsboy problem. Management Sci. 25(5): 498-501]. Specifically, we co...

摘要：Firms require demand forecasts at different levels of aggregation to support a variety of resource allocation decisions. For example, a retailer needs store-level forecasts to manage inventory at the store, but also requires a regionally aggregated forecast for managing inventory at a distribution center. In generating an aggregate forecast, a firm can choose to make the forecast directly based on the aggregated data or indirectly by summing lower-level forecasts (i.e., bottom up). Our study i...

摘要：Cancer is a leading cause of death worldwide, and advanced cancer is often treated with combinations of multiple chemotherapy drugs. In this work, we develop models to predict the outcomes of clinical trials testing combination chemotherapy regimens before they are run and to select the combination chemotherapy regimens to be tested in new phase II and phase III clinical trials, with the primary objective of improving the quality of regimens tested in phase III trials compared to current pract...
