An Increase in Unearned Income Generally Leads to Higher Consumption and More Free Time
For most standard utility functions, a rise in an individual's unearned income will lead them to opt for both more consumption and additional free time. This principle holds true even though the specific mathematical expressions for these changes vary depending on the exact utility function being used.

An Increase in Unearned Income Generally Leads to Higher Consumption and More Free Time
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?
Analyzing Consumer Response to a Subsidy
The price of concert tickets, a good that Sarah frequently purchases, decreases significantly. In response, Sarah not only attends more concerts but also starts buying more expensive merchandise at the concerts, something she rarely did before. Which part of Sarah's new behavior is explained exclusively by the change in her purchasing power?
A government program provides a significant, unconditional monthly cash payment to all its citizens. An economist studying the program's impact observes that, on average, recipients decrease their purchases of generic canned soup but increase their purchases of fresh, high-quality cuts of meat. Which statement provides the best evaluation of this change in consumer behavior?

The Lottery Winner's Decision
An individual starts receiving a large, regular payment from a family trust, an income source that does not depend on the number of hours they work. Subsequently, they decide to reduce their weekly work hours and also buy a more expensive car. Which statement best analyzes the economic reasoning behind this decision?
Statement: If an individual experiences a significant increase in income that is not tied to their work hours, they will always choose to work fewer hours.
Analyzing Responses to Unearned Income
Explaining Choices with Unearned Income
An individual experiences a substantial increase in income from a source that is independent of the hours they work. Assuming this person's preferences are typical, what is the most likely combined effect on their consumption of goods and their allocation of free time?
Alex begins receiving a monthly payment from a family inheritance, an income source that does not depend on work hours. A friend comments, 'That's great! Now you can afford to work less.' Which of the following provides the most accurate economic critique of the friend's comment?
For an individual with typical preferences for consumption and leisure, match each economic scenario with its most probable effect on their choices.
Comparing Responses to a Financial Windfall
An economist observes that when individuals receive a large, work-independent financial windfall, the vast majority choose to both reduce their work hours and increase their spending on goods and services, rather than choosing one extreme (like quitting work entirely or maintaining the same work hours). Which economic principle provides the best explanation for this widely observed choice pattern?
