Transcribed Image Text:7. The information in the Lorenz curve is often summarized in a single measure called the Gini
index (proposed in a 1912 paper by the Italian statistician Corrado Gini). The Gini index is
defined as follows. Let A be the area of the region between y = x and y = L(x) and let B be
the area of the region between y = L(x) and the x-axis (see Figure 1). Then the Gini index
A
is G =
A+B
Compute the Gini index for L, when p = 1.1 and when p = 4.
