Relationship Between Shaded Area, Gini Coefficient, and Inequality
In a Lorenz curve diagram, the shaded area enclosed between the line of perfect equality and the Lorenz curve serves as a direct visual measure of income inequality. An expansion of this area indicates a greater departure from an equal income distribution, which in turn corresponds to a higher Gini coefficient, signifying increased inequality.

A diagram illustrating income distribution shows a line of perfect equality and a Lorenz curve. The area between the line of perfect equality and the Lorenz curve is calculated to be 0.20. The area under the Lorenz curve is calculated to be 0.30. Based on this information, what is the Gini coefficient?
Comparing Income Inequality
Calculating the Gini Coefficient from Lorenz Curve Data
A country implements a new, highly effective progressive tax system where income is collected from the highest earners and redistributed to the lowest earners. How would this change in income distribution affect the country's Lorenz curve and its corresponding Gini coefficient?
In a standard Lorenz curve diagram, a Gini coefficient of 0.4 implies that the area between the line of perfect equality and the Lorenz curve is 0.4.
In a standard Lorenz curve diagram, the area between the line of perfect equality and the horizontal axis is divided into two distinct regions by the Lorenz curve. Let 'Area A' be the region between the line of perfect equality and the Lorenz curve, and 'Area B' be the region under the Lorenz curve. Match each conceptual term with its correct mathematical or geometric representation based on this diagram.
Calculating Area Under the Lorenz Curve
In a standard Lorenz curve diagram, the total area of the triangle formed by the line of perfect equality and the axes is 0.5. If a country's Gini coefficient is 0.3, the area under its Lorenz curve must be ____.

Consider a standard diagram used to represent a country's income distribution, where a curved line shows the cumulative share of income held by a cumulative share of the population. A straight diagonal line on this diagram represents a scenario of perfect income equality. If a country's curved line shifts to be positioned further away from the straight line of perfect equality, what is the resulting effect on the Gini coefficient and the overall level of income inequality?
Analysis of Income Distribution in Two Countries
An economist observes that following the implementation of a new wealth redistribution policy in a country, the area between the line of perfect equality and the Lorenz curve has become smaller. Based on this observation, the economist concludes that the country's Gini coefficient has risen, indicating an increase in income inequality.
