"Preferential Linkage and Network Evolution: A Conceptual Model and Empirical test in the US Video game Sector" Academy of Management Journal 47 (6) (December 2004): 866-892
| We examined how network structure (density overlap and embeddedness) and technology characteristics of a platform (dominance and newness) shaped interorganizational
coordination of product launches in the U.S. video game industry. We found that the developers’ choices to launch games for particular game consoles were significantly
explained by these four factors using multiprobability regression on a primary data set of 2,815 launches between 1995 and 2002. This analysis was complemented
with application of a network visualization technique. |

"The College Textbook Marketplace in the 1990s: McGraw-Hill's Launch of Primis"
| This case introduces Primis, an electronic database publishing system that lets college instructors create a customized textbook tailored to the specific needs of a course. This new technology is making textbooks less expensive, especially since Primis has the capability to produce as many copies as needed quickly. The question is: Can Primis maintain the advantage? What does it need to learn to stay competitive in the market? Finally, what should be its information technology strategy focus? |

Working Papers |
"Performance Effects of Knowledge-Based Diversification: An Emprical Test"
| This study conceptualizes knowledge-based construct to measure knowledge-based synergies of diversified firms. Knowledge-based relatedness is hypothesized to lead to superior performance and to mediate the relationship between diversification and performance. These hypotheses are tested with primary data from senior executives of 303 Fortune 1000 firms. Knowledge-based relatedness has positive and significant associations with both market-based and accounting-based measures of performance. Performance effects of diversification are observed only through the mediation of knowledge-based relatedness. |

"Value Flows in Information Technology Sourcing Alliances: Empirical Results from Over a Decade of Use"
| This study examines value flows in IT sourcing alliances to companies engaged in this tyupe of interfirm relationship over a 12 year period. We anchor this study within the resource-based views of the firm but augment it with innovation and co-opetition perspectives to recognize companies' endowments of IT resources. Using these multiple theoretical perspectives, we develop a set of hypotheses on the patterns of value created and appropriated by buyers and suppliers. We then test them on a 12 year sample of IT sourcing alliances using an event study methodology. We find support for key theoretical assertions of resource-based views of the firm-value flows to those companies that are endowed with scarce and valuable IT resources. We also find support for the competitive erosion of IT resources and that innovation is required to sustain value flows. Finally, we find that companies that cooperate are better able to sustain value flows than companies that do not. We thus provide a more complete and robust set of findings on IT sourcing alliances to stimulate further theorizing and empirical explorations in this important area. |
