Abstract:
|
We examined how self-organizing behavior of individual actors affects the emergence of different types of systemic level networks, a process that drives network evolution and global network behavior. We used networks of actors who collaborate on short-term project teams as our frame of reference and investigated how the choices actors make in picking their teammates determine the global network topology of the entire field. A key analytical feature of our model is that it suggests that differences in the types of links rather than differences in actors’ intrinsic characteristics significantly govern emergence, which enables us to treat emergence in a novel way. We tested our model inductively and deductively, using historical case and a simulation. Our diverse data and tests supported our predictions about the relationship between tie types and the emergence of the network topologies. Moreover, our model explains why some topologies, such as small world networks, have high incidence rates relative to other types of networks, at what junctures during emergence there is rapid shifting or stability between topologies, and why certain tie types disproportionately govern the emergence of the global network. Finally, we formalized our model in analytical solutions that show the common link among the diverse empirical regularities and highlight the model’s contributions to theory on the sociology of networks. |
