The pareto zipf and other power laws

WebbThe interesting part is the coefficient ζ, which is called the power law exponent of the distribution. This exponent is also sometimes called the “Pareto exponent,” because Vilfredo Pareto discovered power laws in the distribution of income (as discussed in Persky 1992). A “Zipf’s law” is a power law with an exponent of 1. WebbZipf's law states that if words of a language are sorted in the order of decreasing frequency of usage, a word's frequency is inversely proportional to its rank, or sequence number in the list.

WebbIt is found that (1) the tails of distributions of size and GDP both obey Pareto Law with the Pareto exponent 1; (2) compared with Pareto exponent in GDP, Pareto exponent in size is bigger. Then an agent model is built to study the underlying formation mechanism of distributions of region size and GDP.
