A graphical curve illustrating income distribution across an economy___________________?
Show answer Hide answer
Answer: A. Lorenz curve
Explanation
A Lorenz curve visually represents income or wealth distribution across a population by plotting cumulative percentages. The curve compares actual distribution against a line of absolute equality to show inequality levels. Therefore, it is the correct graphical tool for analyzing income dispersion. Developed by Max O. Lorenz in 1905, the curve graphs the bottom percentage of households against the cumulative income they earn. A straight diagonal line represents perfect equality, where every household holds an equal share. The Gini coefficient is mathematically derived directly from this graphical curve.
Economists and policymakers use Lorenz curves to evaluate economic disparity and track changes in wealth inequality over time. This analysis helps design tax policies and social programs aimed at supporting lower-income populations. Visualizing inequality aids in communicating complex economic data to the public. Option B refers to consumer preferences rather than income distribution across an entire population. Option C is a linear constraint representing affordable consumption bundles for an individual consumer. Option D is not a standard economic term used for income inequality mapping.
