Data show that an increase in the Gini coefficient is associated with a falling bottom 𝑝𝐵% income share and an increasing top 𝑝𝑇 % income share where, for example 𝑝𝐵 = 40 and 𝑝𝑇 = 1. This relationship, which we call the 𝑋 inequality relationship, is pervasive in the...

Data show that an increase in the Gini coefficient is associated with a falling bottom pB% income share and an increasing top pT% income share where, e.g. pB = 40 and pT = 1. This relationship, which we call the X inequality relationship, is pervasive in the sense that it is observed in many...
