Superlinear Scaling for Innovation in Cities (0809.4994v3)
Published 29 Sep 2008 in physics.soc-ph
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.
