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?

An individual receives a significant salary increase. Following this raise, they begin to travel more frequently for leisure, even though the prices for flights, hotels, and other forms of entertainment have not changed. Which statement provides the most accurate economic explanation for this change in behavior?
