Sensitivity of the Gini Coefficient to Income Redistribution
The Gini coefficient is a dynamic measure that reflects changes in income allocation. If a fixed total income within a population is redistributed among its members, the Gini coefficient will change to represent the new level of inequality. This highlights that the Gini is not just about the total amount of income, but critically, about how that income is distributed.

An economic analyst is comparing two countries. Country X has an income Gini coefficient of 0.25, and Country Y has an income Gini coefficient of 0.55. Both countries have the same average income per person. Based solely on this information, which of the following statements is the most accurate conclusion?

Interpreting Gini Coefficient Values
Consider an economy where, overnight, every single individual's income doubles. As a result, the proportional share of the total income held by each person remains exactly the same. In this scenario, the Gini coefficient for income inequality would also double.
Comparing Income Distributions
Match each description of an economy's income distribution to its corresponding Gini coefficient value or interpretation.
Arrange the conceptual steps for calculating the Gini coefficient for a population in the correct logical order, based on the average difference method.
In a hypothetical economy where one individual earns all of the income and everyone else earns nothing, the Gini coefficient for income inequality would be ____.
An economist is studying income inequality and the effects of government policies in two countries. The data collected shows the Gini coefficient for market income (income before taxes and transfers) and disposable income (income after taxes and transfers) for each country:
- Country A: Market Income Gini = 0.50; Disposable Income Gini = 0.30
- Country B: Market Income Gini = 0.40; Disposable Income Gini = 0.35
Based on this data, which of the following statements represents the most accurate analysis of the situation?

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?

Consider a small economy with four individuals and a total income of $200, distributed as follows: Person A has $10, Person B has $20, Person C has $30, and Person D has $140. Which of the following single income transfers would cause the largest decrease in this economy's Gini coefficient?
Evaluating Income Redistribution Policies
Predicting Gini Coefficient Changes
In a large population with a wide range of incomes, a transfer of $1,000 from the single wealthiest person to the single poorest person will reduce the overall measure of income inequality by the same amount as a transfer of $1,000 from the single wealthiest person to a person with an income exactly at the median.
In a population with a diverse range of incomes, match each income transfer scenario with its resulting effect on the overall measure of income inequality.
A government plans to implement one of three policies to reduce income inequality. Each policy involves transferring the same fixed amount of money from a higher-income individual to a lower-income individual. The population has a continuous and wide distribution of incomes. Arrange the following policies in order, from the one that will cause the largest decrease in the overall measure of income inequality to the one that will cause the smallest decrease.
Evaluating Competing Redistribution Strategies
In a large population with a continuous income distribution, a fixed sum of money is transferred from a person at the 95th income percentile to a person at the 5th income percentile. A second, identical sum is transferred from a person at the 60th percentile to a person at the 40th percentile. The first transfer will cause a ____ reduction in the overall measure of income inequality compared to the second transfer.
Consider a small society with three individuals and a total income of $100, distributed as follows: Person A has $10, Person B has $30, and Person C has $60. Which of the following policy actions, involving a transfer of $5, would result in the greatest increase in income inequality as measured by the Gini coefficient?
