  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 connected by trade between harbored activities, city
size and land value distributions are obtained as higher-order patterns. The
model predicts the empirically observed spatial distribution of land value
density as well as that of urban cluster prices. To connect land value to
population, which is a commonly observed quantity, we also demonstrate that
there is, for urban clusters, a linear relation between accumulated land value
and population.
