An economist is comparing two countries, Country A and Country B. Both countries have an identical Gini coefficient of 0.5, suggesting the same overall level of income inequality. However, their societal structures are very different:

• Country A: A small number of extremely wealthy individuals control a vast majority of the nation's resources, while the rest of the population lives in near-uniform poverty.
• Country B: There are no individuals in extreme poverty or with extreme wealth; instead, there is a wide and continuous spectrum of income from a lower-middle class to an upper-middle class.

Which of the following statements best analyzes this situation?

Analyzing Income Distribution in a Small Economy

Because the Gini coefficient provides a single, comprehensive number to summarize a country's entire income distribution, it is considered the only metric necessary for international comparisons of income inequality.

Match each income inequality metric with the primary aspect of the income distribution it is best suited to highlight.

Rationale for Common Inequality Metrics

An economic report for a country over the last decade reveals two key trends: the Gini coefficient has decreased from 0.45 to 0.42, while the ratio of the income of the 90th percentile to the 10th percentile has increased from 10 to 15. Based on these two metrics, what is the most likely change that has occurred in the country's income distribution?

Policy Advising on Inequality Reduction

Selecting an Inequality Metric for Policy Evaluation

While many metrics exist, the two most frequently used measures for summarizing and comparing income inequality in economic reports and policy debates are the rich/poor ratio and the ____.
