Activity: Calculating Gini Coefficients with Diagrams
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?

Calculating Income Inequality from Distribution Data
Consider an economy represented by a Lorenz curve on a standard 1x1 graph where the x-axis is the cumulative percentage of the population and the y-axis is the cumulative percentage of income. The curve consists of a straight line from the origin (0,0) to the point (0.8, 0.4), and then another straight line from (0.8, 0.4) to the point (1,1). The line of perfect equality is the diagonal from (0,0) to (1,1). Based on this information, what is the Gini coefficient for this economy?
Calculating the Gini Coefficient for a Simple Economy
Consider a small economy where the poorest 80% of the population earns 20% of the total income, and the richest 20% earns the remaining 80%. Assuming the income distribution is represented by a Lorenz curve composed of straight-line segments connecting the origin (0,0), the point representing the poorest group's income share, and the point of perfect equality (1,1), what is the Gini coefficient for this economy?
Consider an economy where the income distribution is represented by a Lorenz curve on a standard 1x1 graph, where the x-axis is the cumulative percentage of the population and the y-axis is the cumulative percentage of income. The curve consists of a straight line from the origin (0,0) to the point (0.5, 0.2), and then another straight line from (0.5, 0.2) to the point (1,1). The line of perfect equality is the diagonal from (0,0) to (1,1). Based on this information, what is the Gini coefficient for this economy?

Comparing Income Inequality in Two Economies
Consider an economy represented by a Lorenz curve on a standard 1x1 graph, where the x-axis is the cumulative share of people from lowest to highest incomes, and the y-axis is the cumulative share of income earned. The curve is formed by two straight line segments: one from the origin (0,0) to the point (0.6, 0.3), and a second from (0.6, 0.3) to the point (1,1). What is the area of the region between the line of perfect equality and this Lorenz curve?
Consider a society where the income distribution is represented by a Lorenz curve on a standard 1x1 graph, where the x-axis represents the cumulative share of people from lowest to highest incomes, and the y-axis represents the cumulative share of income earned. The curve is formed by two straight line segments: one from the origin (0,0) to the point (0.9, 0.5), and a second from (0.9, 0.5) to the point (1,1). What is the Gini coefficient for this society?
Consider an economy where the income distribution is represented by a Lorenz curve composed of two straight-line segments originating from (0,0) and terminating at (1,1). If the Gini coefficient for this economy is 0.3, it is true that the poorest 50% of the population earns 35% of the total income.
