Coordinates of the Second Kink on a Lorenz Curve for an Economy with Labor and Owner Classes
The second kink on a Lorenz curve, which represents an economy with distinct labor and owner classes, corresponds to a specific point. The x-coordinate is the cumulative percentage of the population comprising the labor force (e.g., 90%). The y-coordinate is the cumulative percentage of total income received by this labor force, known as the wage share. The wage share is the fraction of total output paid in wages, which can be represented as $1 - \sigma\sigma$ is the profit share (e.g., 60%).

An economy's income distribution is represented by a curve defined by line segments connecting the coordinates (0,0), (4,0), (90,60), and (100,100). The x-axis represents the cumulative percentage of the population (from poorest to richest), and the y-axis represents the cumulative percentage of total income. Based on this information, what percentage of the total income is earned by the top 10% of the population?
Consider an economy where the distribution of income is represented by a curve connecting the points (0,0), (4,0), (90,60), and (100,100) on a graph where the x-axis is the cumulative percentage of the population (from poorest to richest) and the y-axis is the cumulative percentage of total income. Based on this data, the following statement is true: The wealthiest 10% of the population earns a smaller share of the total national income than the group of individuals between the 4th and 90th population percentiles.

Calculating Income Share for a Population Segment
In an economy, the distribution of income is described by a curve connecting the points (0,0), (4,0), (90,60), and (100,100). The x-axis represents the cumulative percentage of the population from poorest to richest, and the y-axis represents the cumulative percentage of total income. What percentage of the total income is earned by the population segment between the 4th and 90th percentiles?
Calculating a Measure of Income Inequality
An economy's income distribution is described by a curve connecting the points (0,0), (4,0), (90,60), and (100,100), where the x-axis is the cumulative percentage of the population (from poorest to richest) and the y-axis is the cumulative percentage of total income. Match each population segment with its corresponding share of the total income.

Income Distribution in a Two-Class Economy
In an economy where the population is divided into workers and owners, the workers comprise 80% of the population. The share of total income going to owners as profits is 50%. On a Lorenz curve for this economy, what are the coordinates (cumulative % of population, cumulative % of income) of the kink that separates the worker class from the owner class?
Calculating Lorenz Curve Coordinates for a Two-Class Economy
In a simplified economy, 90% of the population are workers who receive their income from wages, and the remaining 10% are owners who receive their income from profits. If the total share of the economy's output paid to owners as profits is 30%, then the second kink on this economy's Lorenz curve would be located at the coordinates (90, 30).
