Lorenz Curve for Spoils Distribution on the Royal Rover
Based on the distribution rules from the articles of the pirate ship Royal Rover, the resulting Lorenz curve for income from captured booty lies very close to the 45-degree line of perfect equality. This graphical representation illustrates the highly egalitarian nature of the pirates' economic system, where the institutional rules ensured that ordinary crew members received a significant share of the spoils.

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?

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 Fairness in a Pirate Economy
The crew of the Royal Rover captures treasure worth 6,600 gold pieces. The ship's articles establish the following distribution system: the Captain and the Quarter Master each receive two shares of the total; four officers each receive one-and-a-quarter shares; and 24 regular crew members each receive a single share. Based on this system, what is the value, in gold pieces, of a single share (a 'dividend')?
Analyzing a Proposed Change to the Royal Rover's Articles
The articles of a pirate ship, the 'Royal Rover', established a system where captured booty was distributed in shares. The captain and quartermaster received two shares each, other officers received between one-and-a-quarter and one-and-a-half shares, and regular crew members received one share. Which of the following statements provides the best economic analysis for this hierarchical distribution?

Resolving an Economic Dispute on the Royal Rover
The articles of the pirate ship 'Royal Rover' defined a specific hierarchy for distributing captured treasure. Match each role on the ship to the number of shares of booty they were entitled to receive.
Dispute Resolution Under Fixed Economic Rules
A pirate ship's articles dictate that for any captured treasure, the captain receives two shares and a regular crew member receives one share. True or False: If the total value of a captured treasure were to double, the absolute difference in value, measured in gold pieces, between the captain's portion and a regular crew member's portion would also double.
The articles of a pirate ship define how captured treasure is distributed. The captain and quartermaster each get 2 shares, four officers each get 1.5 shares, and 30 regular crew members each get 1 share. If the crew captures a treasure worth 10,000 gold pieces, what is the total value, in gold pieces, distributed to all of the regular crew members combined?

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.

A graph can be used to visualize how wealth is distributed within a group. On this graph, a straight 45-degree diagonal line represents perfect equality, where every cumulative percentage of the population holds the same cumulative percentage of the wealth (e.g., the bottom 20% of the population holds 20% of the wealth). A curve that bows away from this line indicates inequality; the further the curve bows, the greater the inequality.
Consider two ships with different institutional rules for dividing treasure:
- Ship A: The captain and quartermaster each receive 2 shares. Key officers receive 1.5 shares. All other crew members receive 1 share.
- Ship B: The captain receives 10 shares. Key officers receive 5 shares. All other crew members receive 1 share.
Two curves are plotted to represent these two systems. Curve 1 bows significantly away from the line of perfect equality. Curve 2 lies very close to the line of perfect equality.
Based on an analysis of their distribution rules, which statement correctly identifies the curve for each ship?

Comparative Analysis of Pirate Economic Systems
A historian makes the following claim: 'The rules for dividing treasure on the pirate ship Royal Rover—where the captain received two shares, some officers received one and a half or one and a quarter shares, and a regular crew member received one share—created a system of extreme wealth inequality. Therefore, a graphical representation of this distribution would show a curve that bows significantly far away from the 45-degree line of perfect equality.' Evaluate whether this claim is true or false.
Explaining the Shape of a Wealth Distribution Curve
A graphical representation can be used to show how wealth is distributed within a population. A straight 45-degree line on this graph represents perfect equality, where everyone receives the same amount. A curve that bows away from this line indicates inequality; the further the curve bows, the more unequal the distribution. Below are four different systems for distributing treasure. Arrange these systems in order from the most equal (whose curve would be closest to the 45-degree line) to the least equal (whose curve would bow furthest from the 45-degree line).
Analyzing Crew Morale and Stability
A graph is used to show how treasure is distributed among a 100-person crew. A straight 45-degree line on the graph represents perfect equality (e.g., the lowest-paid 70 people receive 70% of the treasure). The curved line on the graph represents the ship's actual distribution rules. A specific point on this curve shows that the 70 lowest-paid crew members collectively received 50% of the total treasure. What does this single data point reveal about the ship's distribution system?
A graph can be used to visualize how wealth is distributed within a group. On this graph, a straight 45-degree diagonal line represents perfect equality. A curve that bows away from this line indicates inequality; the further the curve bows, the greater the inequality. Match each of the following treasure distribution systems to the description of its corresponding curve.
A graph can be used to visualize how treasure is distributed among a ship's crew. On this graph, a straight 45-degree line represents a system of perfect equality. A second, curved line represents the actual distribution. The more unequal the distribution, the larger the area between the curved line and the 45-degree line becomes. Given a system where the captain receives two shares and a regular crew member receives one, the area between the two lines is relatively small. If the rules were changed so the captain received twenty shares while a regular crew member still received only one, the area between the two lines would significantly ____.
