When Do Networks Matter? A Study of Tie Formation and Decay

Interorganizational partner selection decisions are plagued with uncertainty. When making partnering decisions, firms strive to answer two questions: does the prospective partner have resources which can be used to generate value in the relationship; and whether the partner will be willing to actively share these resources and cooperate in good faith. Answers to these questions help reduce three types of uncertainty - partner capability uncertainty, partner competitiveness uncertainty and partner reliability uncertainty. For a relationship to benefit both partners, they have to possess complimentary resources of comparable quality, avoid explicit competition as well as be willing to engage in the cooperative behaviors within the confines of their relationship. In this paper we examine the importance of prospective partners' characteristics (differences in size, status and specialization) as well as their network characteristics (existence of a common partner and membership in the same clique) to the formation and longevity of their social relationships as these characteristics reduce firms' value generation and partner reliability uncertainty
