Consider an individual's preferences for daily free time (measured on the horizontal axis) and units of consumption (measured on the vertical axis). A key feature of this individual's preferences is that their indifference curves are parallel to each other. Point A represents a combination of 18 hours of free time and 60 units of consumption. Point B, which is on a higher indifference curve, represents a combination of 18 hours of free time and 80 units of consumption. How does the individual's Marginal Rate of Substitution (MRS) of consumption for free time at Point A compare to their MRS at Point B?

Analyzing Worker Preferences

An individual's preferences for consumption (vertical axis) and free time (horizontal axis) are represented by a set of parallel indifference curves. This implies that as the individual's level of consumption increases, their willingness to give up consumption for an additional hour of free time also increases, even if their amount of free time remains unchanged.

Implications of Parallel Indifference Curves

Worker Preferences and Compensation

Match each description of an individual's preferences for consumption (vertical axis) and free time (horizontal axis) with the corresponding graphical property of their indifference curves.

Evaluating an Assumption about Preferences

Freelancer's Preferences and Windfall Income

An individual's preferences for daily consumption (vertical axis) and free time (horizontal axis) are represented by a set of indifference curves that are parallel to each other. Consider three potential combinations of consumption and free time:

• Point X: 16 hours of free time, 50 units of consumption.
• Point Y: 16 hours of free time, 70 units of consumption.
• Point Z: 16 hours of free time, 90 units of consumption.

How does the individual's willingness to trade consumption for an additional hour of free time (their Marginal Rate of Substitution) compare across these three points?

An individual's preferences for daily consumption (measured on the vertical axis) and free time (measured on the horizontal axis) are represented by a set of parallel indifference curves. At a point where they have 15 hours of free time and 50 units of consumption, their Marginal Rate of Substitution (MRS) is 8. This means they are willing to trade 8 units of consumption for one additional hour of free time. What is their MRS at a different point where they have 15 hours of free time but 75 units of consumption?
