Preferential centrality with a density penalty: formulation and an open-source implementation
Alexander Hellervik
Preferential centrality (Hellervik, Nilsson and Andersson, 2019) models spatial activity through feedback between activity and attraction. We extend it with a density penalty. The…
HierX: Fast Multi-Scale Distance-Decay Interaction on Million-Node Networks
Alexander Hellervik, Joakim Bohlin, Claes Andersson
Many models across the sciences require global distance-decay interactions on large sparse networks. Gravity models, accessibility measures, spatial economic models, and network in…
A spatial network explanation for a hierarchy of urban power laws
Claes Andersson, Alexander Hellervik, Kristian Lindgren
The presented model provides an explanation to several empirically observed phenomena in spatial economics. By representing the system as a complex network of fixed-size land areas…
The urban economy as a scale-free network
Claes Andersson, Alexander Hellervik, Kristian Lindgren +2
We present empirical evidence that land values are scale-free and introduce a network model that reproduces the observations. The network approach to urban modelling is based on th…
