from the “ground state” of pure communism. While inequality indices were devised for socioeconomic applications, they are effectively applicable in the context of general non-negative size distributions such as count,
length, area, volume, mass, energy, and duration. Inequality indices are commonly based on the notion of
Lorenz curves, which implicitly assume the existence of finite means. Consequently, Lorenz-based inequality
indices are excluded from the realm of infinite-mean size distributions. In this paper we present an inequality
index that is based on an altogether alternative Langevin approach. The Langevin-based inequality index is introduced, explored, and applied to a wide range of non-negative size distributions with both finite and infinite
means. |
