Superlinear Scaling for Innovation in Cities
arXiv:0809.4994 · doi:10.1103/PhysRevE.79.016115
Abstract
Superlinear scaling in cities, which appears in sociological quantities such as economic productivity and creative output relative to urban population size, has been observed but not been given a satisfactory theoretical explanation. Here we provide a network model for the superlinear relationship between population size and innovation found in cities, with a reasonable range for the exponent.
