The k-generalized distribution: A new descriptive model for the size distribution of incomes
arXiv:0710.3645 · doi:10.1016/j.physa.2008.01.109
Abstract
This paper proposes the k-generalized distribution as a model for describing the distribution and dispersion of income within a population. Formulas for the shape, moments and standard tools for inequality measurement - such as the Lorenz curve and the Gini coefficient - are given. A method for parameter estimation is also discussed. The model is shown to fit extremely well the data on personal income distribution in Australia and the United States.
