Question

Gini Coefficient.
B = 0.28
Determine the Gini Coefficient.

Answer 1

A = 0.2, B = 0.28, where A is the area between the diagonal and the Lorenz curve, B is the rest area under the diagonal.
Gini Coefficient G = A/(A + B) = 0.2/(0.2 + 0.28) = 0.476, so Gini Coefficient is lower than 0.5 and there is an inequality.
