Two countries, A and B, report their income inequality statistics. Both countries have an identical ratio where the average income of the top 10% of earners is 15 times that of the bottom 10%. However, Country A has a Gini coefficient of 0.35, while Country B has a Gini coefficient of 0.50. What is the most logical conclusion that can be drawn from this data?

Evaluating Income Inequality Measures

Comparing Inequality Measures

Consider a country where a new policy causes a significant transfer of wealth from the middle 50% of earners to the top 20% of earners, but the average incomes of the poorest 10% and the wealthiest 10% of the population remain exactly the same. In this situation, an inequality measure that solely compares the average income of the top 10% to the bottom 10% would fail to detect any change in the country's overall income disparity.

Choosing an Inequality Metric for Policy Analysis

Interpreting Conflicting Inequality Data

Match each statement to the type of inequality measure it best describes.

A country's government introduces a policy that slightly reduces the income of all middle-income earners and transfers this wealth to the top 5% of earners. The average incomes of the poorest 10% and the wealthiest 10% of the population remain unchanged. An inequality measure that only compares the top and bottom income deciles would show no change, but the ________ would increase because it accounts for shifts across the entire income distribution.

Choosing the Right Tool for Inequality Analysis

An economist is comparing income inequality in two countries, Country A and Country B. The data shows that the average income of the wealthiest 10% of the population is exactly 12 times the average income of the poorest 10% in both countries. However, further analysis reveals that in Country A, the incomes of the middle 80% of the population are clustered very closely together. In contrast, in Country B, the incomes of the middle 80% are widely dispersed, with significant gaps between different income levels within this group.

Based on this information, which of the following statements is the most accurate comparison of the two primary inequality measures for these countries?
