Gini Coefficient Calculation in a Three-Person Population (Figure 5.25)
Figure 5.25 illustrates the income differences within a hypothetical three-person population, which are used to calculate the Gini coefficient. The individuals have incomes of $12, $4, and $2, resulting in a total income of $18. The calculation uses the average of the pairwise income differences ($6.67) and the population's average income ($6). Applying the formula, the Gini coefficient is found to be approximately 0.56: This example demonstrates that for a fixed total income, the Gini coefficient is sensitive to how that income is distributed among the individuals.

Calculation of Average Income Difference in the One-Lender, Five-Borrower Model
Consider a population where, due to uniform, non-proportional income growth, the average income doubles. However, the absolute difference in income between every pair of individuals remains exactly the same. Based on the formula that relates the Gini coefficient to the average income difference, what is the resulting effect on the Gini coefficient?

True or False: If a government implements a policy that gives every individual in a population the same fixed amount of money (e.g., a $1,000 universal payment), the Gini coefficient will remain unchanged because the absolute income differences between all pairs of individuals have not changed.
A government is considering several economic policies. Based on the formula that defines the Gini coefficient as a function of average income and the average difference in income between all pairs of people, match each policy scenario with its most likely direct effect on the Gini coefficient.
In an economy, the average income is $60,000, and the average absolute difference in income between all pairs of individuals is $36,000. According to the formula that relates these values, the Gini coefficient for this economy is ____.
To calculate the Gini coefficient from a set of individual incomes using the formula based on average difference, one must follow a specific sequence of calculations. Arrange the following steps in the correct logical order, from first to last.
Two countries, Equatoria and Polaristan, have the exact same average income per person. In Equatoria, incomes are distributed very evenly, with most citizens earning an amount close to the national average. In Polaristan, there is a vast gap between a small, extremely wealthy elite and a large population with very low incomes.
Based on the formula that defines the Gini coefficient in terms of average income and the average difference between all pairs of incomes, which of the following statements is most likely true?
An economic policy is implemented that transfers a sum of money from the single wealthiest individual in a population to the single poorest individual. This transfer is designed so that the total income in the population, and therefore the average income, remains unchanged. Assuming there are more than two people in this population, what is the most likely effect on the measure of inequality that is calculated as half the ratio of the average income difference to the average income?

Calculating Income Inequality in a Small Economy
Consider a small economy with four individuals. Their annual incomes are $10, $20, $30, and $60. Based on the principle of calculating the Gini coefficient from the average income difference between all pairs of individuals, what is the Gini coefficient for this economy?
Analyzing Changes in Income Inequality
Consider a small economy consisting of three individuals with incomes of $2,000, $8,000, and $14,000. If the wealthiest individual gives $3,000 to the poorest individual, the Gini coefficient for this economy will decrease.
Match each three-person economy, described by the annual incomes of its individuals, to its corresponding Gini coefficient. The Gini coefficient is calculated as half the ratio of the average income difference between all pairs of individuals to the population's average income.
To calculate the Gini coefficient for a small population, you must follow a specific sequence of calculations based on the principle of comparing incomes between all pairs of individuals. Given a three-person economy with incomes of $10,000, $20,000, and $60,000, arrange the following steps into the correct logical order required to find the Gini coefficient.
Consider a small economy with three individuals whose annual incomes are $2,000, $4,000, and $12,000. The Gini coefficient, calculated as half the ratio of the average income difference between all pairs to the population's average income, is approximately ____. (Round your answer to two decimal places).
Evaluating Policy Proposals to Reduce Income Inequality
Consider four different three-person economies, each with the same total annual income of $120. The Gini coefficient is calculated as half the ratio of the average income difference between all pairs of individuals to the population's average income. Which of the following income distributions would result in the highest Gini coefficient, indicating the greatest level of income inequality?
