Explaining the emergence of fat-tailed growth-rate distributions in terms of the action of individual agents remains an important open question in the study of socio-economic systems. Studies of organizational growth statistics are limited by the quantity and level of detail of the available information. Large databases have little or no information about the composition of each workplace, and the time-dependent variables are often reported at the level of the organization.
In this empiric study, we use Swedish register data, a quite unique individual-level longitudinal database that provides data on organizational membership of all workers in the Stockholm region, for a period of 14 years (1990-2003). With this dataset, we can analyze how individual attributes are aggregated at the organizational level, and track individual movements on a yearly basis.
We compute statistics for organizational size and growth, and look at their time evolution in the period of analysis. We further study the distribution of individual-level properties across organizations, especially the in- and out-flow of people moving between organizations.
