This study uses Swedish register data to bring a network perspective into the statistical analysis of organizational growth. The data is a unique individual-level longitudinal database on organizational membership for all workers in the Stockholm region, during the period 1990-2003. We can keep track of organizations and individuals over time, and people's movements between organizations can be known on a yearly basis.
We construct a network where the nodes are organizations, and the links are movements of people between them, during a given year. Firstly, we study the network properties of a collapsed network for the whole time period, and compute probability distributions for the main connectivity and centrality statistics. Secondly, we look at the time evolution of network measures and flows of people between organizations. We explore the scaling of network properties with company size, as well as differences in the statistics for the public and private sectors.
Keywords: complex networks, sociophysics, organizational growth process, scaling.
