摘要：W e propose a pure 0-1 formulation for the wireless network design problem, i.e., the problem of configuring a set of transmitters to provide service coverage to a set of receivers. In contrast with classical mixed-integer formulations, where power emissions are represented by continuous variables, we consider only a finite set of power values. This has two major advantages: it better fits the usual practice and eliminates the sources of numerical problems that heavily affect continuous models...

摘要：Business groups are key sources of innovation in emerging market economies, but we understand little about why innovativeness differs across groups and over time. Variation in the density of intragroup buyer-supplier ties, which are common structural linkages among group affiliates, can help explain both cross-sectional and temporal heterogeneity of group innovativeness. We argue that greater buyer-supplier density within a group initially creates combinatorial opportunities that contribute to...

摘要：T he extensive use of information technologies by organizations to collect and share personal data has raised strong privacy concerns. To respond to the public's demand for data privacy, a class of clustering-based data masking techniques is increasingly being used for privacy-preserving data sharing and analytics. Although they address reidentification risks, traditional clustering-based approaches for masking numeric attributes typically do not consider the disclosure risk of categorical con...

摘要：We measure the effects of pre- and postrelease blog volume, blog valence, and advertising on the performance of 75 movies in 208 geographic markets in the United States. We attribute the variation in blog effects across markets to differences in demographic characteristics of markets combined with differences across demographic groups in their access and exposure to blogs as well as their responsiveness conditional on access. We study the effects of prerelease factors on opening day box office...

摘要：This paper examines how firms' organizational form affects prices negotiated. Negotiated prices are one factor determining whether a vendor or customer captures the value from a transaction. Firms that systematically negotiate more effectively capture more value. Research has investigated individual- and market-level determinants of negotiation outcomes, but little has been done on the firm-level determinants of negotiated prices. I present a first look at one feature, sales process: whether s...

摘要：Previous research in economics shows that compensation based on the pay-for-performance principle is effective in inducing higher levels of effort and productivity. On the other hand, research in psychology argues that performance-based financial incentives inhibit creativity and innovation. How should managerial compensation be structured if the goal is to induce managers to pursue more innovative business strategies? In a controlled laboratory setting, we provide evidence that the combinatio...

摘要：This paper shows that corporate social responsibility (CSR) and firm value are positively related for firms with high customer awareness, as proxied by advertising expenditures. For firms with low customer awareness, the relation is either negative or insignificant. In addition, we find that the effect of awareness on the CSR-value relation is reversed for firms with a poor prior reputation as corporate citizens. This evidence is consistent with the view that CSR activities can add value to th...

摘要：This paper assesses the validity and accuracy of firms' backward patent citations as a measure of knowledge flows from public research by employing a newly constructed data set that matches patents to survey data at the level of the research and development lab. Using survey-based measures of the dimensions of knowledge flows, we identify sources of systematic measurement error associated with backward citations to both patent and nonpatent references. We find that patent citations reflect the...

摘要：We analyze price and quality competition in a vertically differentiated duopoly in which consumers have a preference for variety. The preference for variety is a consequence of diminishing marginal utility for repeated experiences with the same product. We find consumer variety seeking can either soften or intensify price competition, depending on the difference in firm qualities and the strength of consumer preference for variety When the qualities are similar (or the consumer preference for ...

摘要：In diagnostic services, agents typically need to weigh the benefit of running an additional test and improving the accuracy of diagnosis against the cost of delaying the provision of services to others. Our paper analyzes how to dynamically manage this accuracy/congestion trade-off. To that end, we study an elementary congested system facing an arriving stream of customers. The diagnostic process consists of a search problem in which the service provider conducts a sequence of imperfect tests ...
