This means that the coefficient can take on values between zero and one. A Gini Coefficient of one states complete inequality. That is, one single person receives all the income or holds all the wealth of the economy, while all others receive or own nothing. A Gini Coefficient of zero implies perfect equality. That is, all individuals obtain the same income. See the discussion of the Lorenz Curve for a clear illustration of the concept.  Continue reading The Gini Coefficient
