Details

Medeiros (2006) defined an affluence gap:

R^{Med}(\mathbf{x})=\frac{1}{n} ∑_{i=1}^{n}(x_i - ρ)_{+}=\frac{1}{n} ∑_{i=1}^{n} \max ≤ft\{x_i-ρ,0 \right\},

where x_i is an income of individual i, n is the number of individuals, ρ is the richness line. Medeiros' index is not standarized and is an absolute measure of richness.
