Zero Income Effect on Free Time (Figure 3.12)
This example illustrates a specific type of preference where an increase in non-labor income does not lead to a change in the amount of free time chosen. For a student with these preferences, depicted in Figure 3.12, the Marginal Rate of Substitution (MRS) is identical at every level of free time across different indifference curves. Consequently, this student would maintain their original amount of leisure and allocate the entire $1,000 gift towards increased consumption.

Zero Income Effect on Free Time (Figure 3.12)
Two individuals, Sofia and Liam, both receive an unexpected, permanent increase in their daily non-wage income. Sofia has a strong preference for leisure and relaxation. Liam has a strong preference for consuming goods, which he purchases with his wage earnings. Assuming both can freely choose their hours of work, which of the following statements best analyzes the most likely change in their choice of free time?
Analyzing Work-Leisure Choices
Analyzing Preferences and Work Choices
An individual's response to a change in non-wage income depends on their personal preferences for consumption and free time. Match each description of an individual's preferences to the most likely outcome on their choice of free time after receiving a significant, unconditional cash gift.
An individual who works 40 hours per week receives a large, unconditional cash inheritance. After receiving the inheritance, they continue to work 40 hours per week. This outcome implies that the individual places no value on having additional free time.
Analyzing Responses to Increased Income
An individual receives a significant, unexpected increase in their daily non-wage income. They have a very strong preference for material goods over leisure. As a result of this income increase, the change in the number of hours they choose for free time each day will be close to ______.
Consider an individual's choice between daily consumption and hours of free time, represented on a graph where the budget constraint shows all possible combinations. The individual receives a significant, unconditional daily payment that does not depend on work hours, causing their budget constraint to shift outward, parallel to the original. On this new, higher budget constraint, they choose a new point that involves more consumption but fewer hours of free time than their initial choice. What does this behavioral change reveal about the individual's preferences?

MRS in Quasi-Linear Preferences Depends Only on the Non-Linear Good
A consumer's preferences for concert tickets (Good X) and all other goods (measured in money, Good Y) are structured in a specific way. For any given number of concert tickets, the consumer's willingness to give up money for one more ticket is the same, regardless of how much money they currently possess. Graphically, this results in indifference curves that are vertical translations of one another. What is the direct implication of this preference structure for the consumer's Marginal Rate of Substitution (MRS)?

Identifying Preference Structures from Behavior
Consider an individual's preferences for two goods: weekly data allowance (measured in gigabytes) and all other consumption (measured in dollars). If this individual's willingness to give up dollars for an additional gigabyte of data is lower when they have a high income compared to when they have a low income, holding their data allowance constant, then their preferences can be described as quasi-linear.

Analyzing the Marginal Rate of Substitution
Two individuals, Alex and Ben, have identical preferences for weekly data usage (measured in gigabytes, GB) and all other goods (measured in dollars, $). Their preferences are quasi-linear, meaning their willingness to pay for an extra GB of data does not depend on how many dollars they have. Currently, Alex has 5 GB of data and $100, while Ben has 5 GB of data and $200. How does Alex's Marginal Rate of Substitution (MRS) of dollars for data compare to Ben's?

Choice under an Income Windfall
An individual's preferences for daily consumption and hours of free time are such that their indifference curves are vertically parallel. This means that for any given amount of free time, the slope of all indifference curves passing through that point is identical. If this individual receives a large, unexpected, non-work-related cash payment, what is the most likely outcome regarding their choices?
Consider an individual whose preferences for consumption and free time can be represented by indifference curves that are vertically parallel. This means that for any given amount of free time, the slope of every indifference curve is the same. True or False: This individual would be willing to give up more consumption for an extra hour of free time when they have a high income compared to when they have a low income.
Analyzing Preferences from Observed Behavior
Policy Evaluation for Atypical Preferences
An individual makes choices between daily consumption and hours of free time. Match each description of their preferences or behavior with the corresponding economic concept or implication.
An individual currently works 35 hours per week. They receive an unexpected inheritance that provides them with a stable, additional income of $1,000 per month, which does not depend on the number of hours they work. If this individual's preferences for consumption and free time are such that any change in their non-labor income has no effect on their desired amount of free time, the change in their weekly work hours will be ____ hours.
An individual works a set number of hours per week. They receive an unexpected, weekly cash grant from a government program that does not depend on their work hours. After receiving the grant, they continue to work the same number of hours as before, but their weekly spending on goods and services increases by the exact amount of the grant. Which of the following descriptions of their indifference map (representing preferences for consumption and free time) is consistent with this behavior?
An individual's preferences are such that their choice of how many hours to work is completely unaffected by receiving a non-wage-related cash prize. Which statement provides the most accurate economic explanation for this behavior?
An individual's work schedule remains unchanged after the government imposes a new annual lump-sum tax, which reduces their overall income but does not depend on hours worked. However, this same individual chooses to work a different number of hours when their employer reduces their hourly wage. Which of the following descriptions of this individual's preferences, represented by indifference curves on a graph with consumption on the y-axis and free time on the x-axis, is the most consistent with their behavior?
