INTERFIRM STRATEGIC INFORMATION FLOWS IN LOGISTICS SUPPLY CHAIN RELATIONSHIPS Klein, Richard and Rai Arun. MIS Quarterly; December 2009, Vol. 33 Issue 4, p735-762, 28p.
Abstract: This paper focuses on strategic information flows between buyers and suppliers within logistics supply chain relationships and on subsequent relationship-specific performance outcomes. Our analysis of dyadic data collected from 91 buyer--supplier logistics relationships finds that buyer and supplier strategic information flows positively impact the relationship-specific performance of both sharing and receiving parties. Specifically, each party gains financially from improved management of assets, reduced costs of operations, and enhanced productivity. Moreover, each benefits operationally from improved planning, control, and flexibility of resources. Buyer dependence on the supplier increases buyer strategic information flows to the supplier. Additionally, buyer IT customization and both buyer and supplier trusting beliefs in the receiving party positively impact strategic information sharing with partners. This study suggests that partnerships for supply chain services engage in cooperative initiatives to generate relational rents and are an alternative to conventional "arms length" transactional exchanges. These partnerships need to be motivated to go beyond the sharing of order-related information (which must occur in transactional exchanges) and to share strategic information (which has the potential for both additional rent generation and risks of misappropriation).
BUSINESS VALUE OF PARTNER’S IT INTENSITY: VALUE CO-CREATION AND APPROPRIATION BETWEEN CUSTOMERS AND SUPPLIERS Vernon Richardson, Rod Smith, Pankaj Setia, Working Paper, University of Arkansas.
Abstract: This research examines value impacts of a partner’s IT usage in a customer-supplier network. Prior research assessing network level dynamics of IT have examined industry level effects, and in this research we extend the examination to the level of a dyad. Specifically, we examine partner related value creation, co-creation and appropriation of value between firms within customer-supplier relationships. SEC Filings are used to identify approximately 5,868 unique dyadic pairs of customer-supplier over the period 1991 to 2005, and hypothesis are tested using a sample of 15,028 customer-supplier dyad-years. Our results indicate that a partner’s IT usage co-creates value for the overall relationship, and relative value impacts of a firm’s own and partner’s IT intensity may be different. Also, contrary to views of customer’s exploitation of supplier, our study finds that an increased IT intensity enhances the probability of value being generated for both the partners in a dyad.
ON-LINE SOCIAL NETWORKS IN ECONOMICS Adalbert Mayer. Decision Support Systems Vol. 47 Issue 3, June 2009, Pages 169-184
Abstract: This paper describes how economists study social networks. While economists borrow from other fields like sociology or computer science, their approach of modeling of social networks is distinguished by the emphasis on the role of choices under constraints. Economists investigate how socioeconomic background and economic incentives affect the structure and composition of social networks. The characteristics of social networks are important for economic outcomes like the matching of workers to jobs and educational attainment. I review the theoretical and empirical literature that investigates these relationships and discuss possible implications of new, Internet based, forms of social interactions.
VIRTUAL WORLDS-PAST, PRESENT, AND FUTURE: NEW DIRECTIONS IN SOCIAL COMPUTING Paul R. Messinger, Eleni Stroulia , Kelly Lyons, Michael Bone, Run H. Niu, Kristen Smirnov and Stephen Perelgut , Decision Support Systems, Vol. 47 Issue 3, June 2009, Pages 204-228
Abstract: Virtual worlds, where thousands of people can interact simultaneously within the same three-dimensional environment, represent a frontier in social computing with critical implications for business, education, social sciences, and our society at large. In this paper, we first trace the history of virtual worlds back to its antecedents in electronic gaming and on-line social networking. We then provide an overview of extant virtual worlds, including education-focused, theme-based, community-specific, children-focused, and self-determined worlds – and we analyze the relationship among these worlds according to an initial taxonomy for the area. Recognizing the apparent leadership of Second Life among today's self-determined virtual worlds, we present a detailed case study of this environment, including surveys of 138 residents regarding how they perceive and utilize the environment. Lastly, we provide a literature review of existing virtual world research, with a focus on business research, and a condensed summary of research issues in education, social sciences, and humanities.
Are online auction markets efficient? An empirical study of market liquidity and abnormal returns Robert J. Kauffman, Trent J. Spaulding, and Charles A. Wood, Decision Support Systems Vol. 48 Issue 1, December 2009, Pages 3-13
Abstract: Technological advances have facilitated investment in collectibles through online auction markets, where information regarding product characteristics, current and historical prices, and product availability is available to millions of market participants. However, market inefficiencies may still exist, where prices do not reflect market information and where savvy speculators can profit. Using unit root and variance ratio tests, we examine 8538 rare stamp and 56,997 rare coin auctions to evaluate the efficiency of online markets. In particular, we study market liquidity, abnormal returns and weak-form efficiency. We find an inverse relationship between market efficiency and liquidity. Bidder competition intrinsic to liquidity increases the chances that uninformed bidders drive up item prices, leading to the observed market inefficiencies. |
