Figures 3.11 and 3.12 as Illustrations of the Income Effect
Figures 3.11 and 3.12 serve as key examples illustrating the income effect. They demonstrate how individuals with different preferences respond to an increase in income. Figure 3.11 showcases a positive income effect, where more free time is chosen, whereas Figure 3.12 depicts a zero income effect, where the amount of free time chosen remains unchanged.

Impact of a Windfall on Consumer Behavior
Suppose the price of gasoline, a good that a commuter purchases regularly, falls significantly. As a result, the commuter finds they have more money left over after filling up their tank each week. They use this extra money to start buying a premium coffee on their way to work, a luxury they previously avoided. Which statement best explains the commuter's decision to buy the coffee?
Isolating the Purchasing Power Effect
An employee knows there is a consistent, but random, chance they will be caught if they decide not to put in effort during any given pay period. To decide whether the risk is worth it, they need to weigh the benefit of avoiding effort against the potential cost of being fired. According to the standard economic model for this situation, how should the employee approach calculating the total potential benefit of shirking?
The income effect refers to the change in the quantity of a good a person chooses to buy that results from that good becoming relatively cheaper or more expensive than other goods.
A consumer's favorite brand of coffee goes on sale, reducing its price by 50%. The consumer observes that they now have more money left in their weekly grocery budget. They use this extra money to buy more fresh fruit, a completely unrelated product. Which of the following statements best dissects the consumer's decision to buy more fruit?

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?
