An economy consists of two people, Priya and Quentin, and a total of 10 divisible units of a good. Consider the following two allocations:

• Allocation X: Priya has 9 units and Quentin has 1 unit. This allocation is Pareto efficient.
• Allocation Y: Priya has 5 units, Quentin has 4 units, and 1 unit is unused. This allocation is Pareto inefficient.

Based on this information, which statement provides the most accurate analysis of these allocations from the individuals' perspectives?

Consider an economy with two individuals. If an allocation of resources is Pareto efficient, it means that both individuals are better off under this allocation than they would be under any possible Pareto inefficient allocation.

Evaluating Resource Allocations

Efficiency vs. Individual Preference

Preference and Efficiency

Imagine an economy with two individuals, Sam and Alex. Match each description of a resource allocation or a change between allocations with the economic concept it best illustrates.

Farmer Allocation Preferences

An individual might rationally prefer a specific Pareto inefficient resource allocation over a different Pareto efficient one if the inefficient allocation provides them with a higher personal level of ________.

An economy has two individuals, Anya and Ben. Consider two possible resource allocations:

• Allocation A (Inefficient): Anya's utility is 10; Ben's utility is 10.
• Allocation B (Efficient): Anya's utility is 20; Ben's utility is 5.

Based on this information, which of the following statements is true?

Two individuals, Alex and Ben, have access to a shared resource that can generate a total of 100 units of value if used fully. Consider three possible scenarios for how the resource is used:

• Scenario X (Inefficient): The resource is used in a way that generates only 80 units of total value. From this, Alex receives 60 units of value and Ben receives 20 units.
• Scenario Y (Efficient): The resource is used fully, generating 100 units of total value. From this, Alex receives 70 units of value and Ben receives 30 units.
• Scenario Z (Efficient): The resource is used fully, generating 100 units of total value. From this, Alex receives 50 units of value and Ben receives 50 units.

Which of the following statements provides the most accurate analysis of these scenarios from the individuals' perspectives?
