Position in formal structure, personal characteristics and choices of advisors in a law firm: a logistic regression model for dyadic network data

This paper presents a statistical model for the analysis of binary sociometric choice data, the P2 model,which provides a flexible way for using explanatory variables to model network structure. It is applied toexamine the influence of the formal structure of an organization on interactions among its members. It isshown to provide a general and precise method for addressing this substantive issue. We identify the respective effects of position in the formal structure (status, seniority, division of work and office membership) and selected personal characteristics of members of a corporate law firm on their choices of advisors. Flows of advice are shown to be consistently shaped by status games and the pecking order in the firm. Other dimensions help members in mitigating the effect of this strong rule. This approach ultimately provides more understanding of how members of such firms try to balance cooperation and competition in terms of access to and management of key resources
