Question
f. What is the smallest interval \( [a, b] \) on which values of the \( G \) ini index lie for \( L(x)=x^{p} \) with \( p \geq 1 \) ? The minimum value of \( G \) is 0 and the maximum value of \( G \) is 1 . Which endpoints of \( [a, b] \) correspond to the least and most equitable distribution of wealth? \( G=\square \) corresponds to the least equitable and \( G=\square \) corresponds to the most equitable distribution of wealth.

Answer
The smallest interval for the Gini index \( G \) is \([0, 1]\).
- \( G = 1 \) represents the least equitable distribution of wealth.
- \( G = 0 \) represents the most equitable distribution of wealth.
So, the endpoints are:
- \( G = 1 \) for the least equitable distribution.
- \( G = 0 \) for the most equitable distribution.
Solution
The **Gini index** measures the inequality of a distribution, such as income or wealth distribution, and it ranges between 0 and 1:
- **0** represents perfect equality, where everyone has the same wealth.
- **1** represents maximal inequality, where one individual has all the wealth, and everyone else has none.
Given the function \( L(x) = x^{p} \) with \( p \geq 1 \), the smallest interval \([a, b]\) on which the Gini index \( G \) lies is:
\[
[0, 1]
\]
Within this interval:
- **\( G = 1 \)** corresponds to the **least equitable distribution** of wealth. This means that wealth is concentrated in the hands of a single individual or a very small group, with everyone else having little to none.
- **\( G = 0 \)** corresponds to the **most equitable distribution** of wealth. In this scenario, wealth is perfectly evenly distributed among all individuals, with no disparities whatsoever.
So, the filled-in statements are:
\[
G = 1 \text{ corresponds to the least equitable distribution of wealth and } G = 0 \text{ corresponds to the most equitable distribution of wealth.}
\]
**Summary:**
- **Smallest Interval for \( G \):** \([0, 1]\)
- **Least Equitable Distribution:** \( G = 1 \)
- **Most Equitable Distribution:** \( G = 0 \)
**Final Statement:**
The smallest interval is [0, 1]. G = 1 corresponds to the least equitable distribution of wealth and G = 0 corresponds to the most equitable distribution of wealth.

The smallest interval \( [a, b] \) for the Gini index \( G \) when evaluating the function \( L(x) = x^p \) with \( p \geq 1 \) is \( [0, 1] \). The minimum value \( G = 0 \) signifies a perfectly equitable distribution of wealth, where everyone has the same income. On the other hand, the maximum value \( G = 1 \) indicates a completely inequitable distribution, where one person has all the income and everyone else has none. Thus, \( G = 1 \) corresponds to the least equitable distribution and \( G = 0 \) corresponds to the most equitable distribution of wealth.
