摘要：As companies continue to make large investments in information technology ( IT), questions about how and in what contexts such investments pay off have gained importance. We develop a theoretical framework to explain how IT investments could pay off in the economically significant context of corporate diversification, and empirically find that the performance pay off to IT investments is greater for firms with greater levels of diversification. We also find that the performance payoff to IT in...

摘要：Companies spend hundreds of millions of dollars annually on advertising to build and maintain awareness for their brands in competitive markets. However, awareness formation models in the marketing literature ignore the role of competition. Consequently, we lack both the empirical knowledge and normative understanding of building brand awareness in dynamic oligopoly markets. To address this gap, we propose an N-brand awareness formation model, design an extended Kalman filter to estimate the p...

摘要：We study periodic-review inventory replenishment problems with fixed ordering costs, and show the optimality of (s, S) inventory replenishment policies. Inventory replenishment is instantaneous, i.e., the lead time is zero. We consider several sales mechanisms, e. g., auction mechanisms, name-your-own-price mechanisms, and multiple heterogeneous sales channels. We prove this result by showing that these models satisfy a recently-established sufficient condition for the optimality of (s, S) pol...

摘要：The newsvendor model captures the trade-off faced by a decision maker that needs to place a firm bet prior to the occurrence of a random event. Previous research in operations management has mostly focused on deriving the decision that minimizes the expected mismatch costs. In contrast, we present two methods that estimate the unobservable cost parameters characterizing the mismatch cost function. We present a structural estimation framework that accounts for heterogeneity in the uncertainty f...

摘要：This paper characterizes the conditions for strong risk aversion and second-order stochastic dominance for cumulative prospect theory. Strong risk aversion implies a convex weighting function for gains and a concave one for losses. It does not necessarily imply a concave utility function. The latter does follow if the weighting functions are continuous. By investigating the exact relationship between loss aversion and strong risk aversion, a natural index for the degree of loss aversion is der...

摘要：Product recommendation models are key tools in customer relationship management (CRM). This study develops a product recommendation model based on the principle that customer preference similarity stemming from prior purchase behavior is a key element in predicting current product purchase. The proposed recommendation model is dependent on two complementary methodologies: joint space mapping (placing customers and products on the same psychological map) and spatial choice modeling (allowing ob...

摘要：Recently, an agile software development technique called extreme programming has caught the attention of practitioners and researchers in the software industry. A core practice of extreme programming is pair programming, where two developers work on the same piece of code. We introduce the problem of assigning pairs of developers to modules so as to maximize the commonality -a measure of the extent to which common developers work on related modules -subject to a load-balancing constraint that ...

摘要：In purchase situations where attribute information is either missing or difficult to judge, a well-known heuristic that consumers use to form evaluations is the halo effect. The psychology literature has widely considered the halo a reflection of consumers' inability to discriminate between different attributes and have therefore labeled it the halo error or the logical error. The objective of this paper is to offer a rationale for the halo effect. We use a decision-theory framework to show th...

摘要：Although previous scholars have examined the value of virtual communities to customers, in this study we investigate the role of a firm's efforts in cultivating trust and harvesting value for themselves via the virtual communities that they sponsor. We hypothesize that the perceptions of a firm's efforts to provide quality content, to foster member embeddedness, and to encourage interaction foster favorable customer beliefs about and trust in a virtual community sponsor. Further, we hypothesiz...
