Abstract: Collaboration networks are studied as an example of growing bipartite networks. These have been previously observed to exhibit structure such as positive correlations between nearest-neighbour degrees. However, a detailed understanding of the origin of such and the growth dynamics is lacking. Both of these issues are analysed empirically and simulated using various models. A new growth model is presented, incorporating empirically necessary ingredients such as bipartiteness and sublinear preferential attachment. This, and a recently proposed model of team assembly, both agree roughly with some empirical observations and fail in several others.
