The strategic impetus for social network ties: reconstituting broken ceo friendship ties

Research on organization–environment relations has focused primarily on formal linkages between organizations such as board interlock ties as a strategy for managing resource dependence. This study examines whether top corporate executives may maintain more informal ties to executives of other firms in order to manage uncertainty arising from resource dependence. Our point of departure is prior research on boards of directors that has examined whether so‐called ‘broken board ties’ (i.e., ties that are disrupted due to executive turnover) tend to be reconstituted, and whether resource dependence explains the likelihood of reconstitution. These studies have generally provided little evidence that corporate board ties are used to manage resource dependence. We draw from theory and research on social embeddedness and friendship to suggest that, as a strategy for managing dependence, the maintenance of friendship ties between top executives provides benefits that are comparable to the supposed benefits of board cooptation, while imposing fewer constraints on the organization. Our theory leads to the contention that, despite limited prior evidence that resource dependence determines the formation of formal board ties, corporate leaders may nevertheless reconstitute informal (i.e., friendship) ties to leaders of other firms that have the power to constrain their firms' access to needed resources when those ties have been disrupted (e.g., due to turnover of the CEO's friend). We test our hypotheses with a unique dataset that includes survey data from U.S. corporate leaders collected at two points in time, thus permitting an assessment of whether top executives reconstitute broken social ties to leaders of other firms, and whether various sources of resource dependence predict the likelihood of reconstitution. We discuss implications for strategic perspectives on inter‐organizational relations and the sociological literature on embeddedness. Copyright © 2006 John Wiley & Sons, Ltd.     

企业成长的一个悖论分析:效率与适应

企业是追求效率机制的经济实体,在成长过程中有维持内部稳定的内生性倾向。这种固有倾向使得企业在长期发展中面临着能力僵化,无法适应环境变化的危险。因此,企业在追求效率和追求长期适应能力上有着一个尴尬境地,产生了企业成长的一个悖论。为解开这个悖论,把企业家精神、网络联盟和柔性组织结构放入考虑的框架内,从而找到解决的方法。

When a Loser Gains: Free Riding in the Innovation of Network Goods

We consider duopolists innovating and producing a good subject to network externalities. If successful in R&D, a firm sells both the old product and the new one. The new product increases the utility of its user; it also generates a higher network externality than does the old product. A firm which fails to innovate nevertheless profits from the success of the rival: the network effect raises the value of the old product it still produces. A firm free-rides on the innovative efforts of another firm, reducing the incentives of any firm to innovate.
