Emergence of social inequality in the spatial harvesting of renewable public goods
For the sake of illustration, only a single consumer is shown. (A) Consumers harvest the resource in their neighborhoods at a rate that declines with the distance from their locations. (B) When the local resource density falls below a threshold, consumers disperse to other locations at distances randomly drawn from a normal distribution. (C) Once consumers have dispersed, the resource densities around their original location can rebound.
