Using the Lorenz Curve to Compare Pirate and Naval Inequality
The Lorenz curve is an effective tool for contrasting wealth distribution in different organizations, such as eighteenth-century pirate ships and naval vessels. While the egalitarian rules on a pirate ship like the Royal Rover led to a Lorenz curve close to the line of perfect equality, the distribution on naval ships was far more skewed. For example, on the British ships Favourite and Active, the Lorenz curves revealed that ordinary sailors received only about a quarter of the prize money, with the majority going to officers. This stark difference highlights how the institutional structures of piracy fostered greater economic equality compared to the rigid hierarchy of the navy.

Using the Lorenz Curve to Compare Pirate and Naval Inequality
Consider two countries, Country X and Country Y. When their respective income distributions are plotted graphically, the curve for Country X is positioned significantly closer to the 45-degree line of perfect equality than the curve for Country Y. Based solely on this information, which of the following statements is the most accurate conclusion?
A small economy has 10 individuals. To analyze its income distribution, their annual incomes are arranged in ascending order: $10,000, $10,000, $20,000, $20,000, $30,000, $40,000, $50,000, $60,000, $80,000, and $100,000. Based on this data, what percentage of the total economy's income is held by the poorest 50% of individuals?
Analyzing an Extreme Case of Wealth Distribution
Evaluating a Policy's Impact on Income Distribution
On a standard graph representing income distribution for a country, the plotted curve runs horizontally along the x-axis from the origin (0% of the population) to the 40% mark, and only then begins to curve upwards. What does this initial flat segment of the curve indicate about the country's economy?
You are given raw income data for every household in a country. Arrange the following steps in the correct sequence to construct a graphical representation of this country's income distribution.
True or False: If a graphical representation of income distribution is constructed by ordering the population from highest income to lowest income (instead of the standard lowest to highest), the resulting curve would lie above the 45-degree line of perfect equality.
Match each description of an income distribution scenario with the corresponding feature on a standard graphical representation of income inequality, where the x-axis represents the cumulative percentage of the population and the y-axis represents the cumulative percentage of total income.
Interpreting Different Shapes of Inequality
On a standard graphical representation of a country's income distribution, the plotted curve passes through the coordinate point where the cumulative share of the population is 80% and the cumulative share of income is 45%. What is the correct interpretation of this point?

Evaluating Wealth Distribution in Maritime Crews
Consider two eighteenth-century maritime crews with different systems for distributing captured treasure. Crew A operates under a strict hierarchy where officers receive disproportionately large shares, leaving a small fraction for the common sailors. Crew B follows a set of articles ensuring a much more even distribution, where each member's share is clearly defined and the difference between the highest and lowest shares is relatively small. If you were to plot a graphical representation of each crew's wealth distribution, with the cumulative percentage of the crew on one axis and the cumulative percentage of treasure they receive on the other, what would you expect to observe?
Explaining Distributional Differences
Match each description of a system for distributing spoils among a ship's crew to the corresponding characteristic of its graphical representation of inequality, where the axes plot the cumulative percentage of the crew against the cumulative percentage of spoils they receive.
