Original Paper


This article proposes the κ-generalized distribution as a descriptive model for the distribution and dispersion of income within a population based on the deformed exponential and logarithm functions recently introduced by Kaniadakis (Phys A 296:405–425, 2001; Phys Rev E 66:056125, 2002; Phys Rev E 72:036108, 2005). Expressions are reported which facilitate the analysis of the associated moments and various tools for the measurement of inequality. An empirical application, including a comparison of alternative distributions, is made to household income data in Italy for the years 1989 to 2006.
