An economist observes two individuals, Maria and David, who both face the same hourly wage. Maria chooses to work 30 hours per week, while David chooses to work 50 hours per week. Assuming both individuals are making their most preferred choice given their circumstances, what is the most logical conclusion to draw about their preferences?

Evaluating Inferences from Observed Choices

Inferring Preferences from a Policy Change

An economist observes that after a significant wage increase, an individual continues to work the exact same number of hours per week. Based on this observation alone, the economist can conclude that the individual's underlying preferences for income versus free time have remained unchanged.

The Logic of Inferring Preferences

An economist observes the work-leisure choices of four different individuals under different circumstances. Match each observed behavior to the most likely inference about the individual's underlying preferences.

An economist observes that a freelance graphic designer chooses to work 25 hours in a particular week, earning a total of $1,000. Assuming this choice represents the designer's most preferred outcome given their circumstances for that week, which of the following is the most precise inference that can be made based only on this single observation?

Critiquing an Economic Inference

An economist observes that an office worker is employed for a standard 40-hour work week and concludes that this individual's optimal choice is to work exactly 40 hours. Which of the following statements presents the most significant potential flaw in this conclusion?

An economist observes that after an individual's hourly wage increases from $20 to $25, the individual reduces their weekly working hours from 40 to 30. This results in a decrease in their total weekly income (from $800 to $750). Assuming this behavior reflects the individual's most preferred choice under the new circumstances, which of the following is the most defensible inference?
