An economist uses a simple model that only considers how wage changes affect an individual's choice between consumption and free time. The model predicts that as a country's average wage rises, its citizens will work fewer hours. However, when comparing two countries with similar histories of strong wage growth, the economist finds that working hours decreased significantly in one country but remained high in the other. Which of the following best explains the model's failure to predict the outcome in both countries?

Critique of a Simplified Work-Leisure Model

A simple economic model, which assumes all factors other than individual preferences for consumption and free time are held constant, is sufficient for explaining why working hours have evolved differently in various countries over the past century.

An economist is using a simplified model to analyze work-leisure choices. The model assumes that only an individual's wage and their personal preference for goods versus free time affect their decision on how many hours to work. Match each real-world factor, which is excluded from this model, to the specific way it could limit the model's accuracy in explaining working hour trends.

Evaluating a Policy Recommendation Based on a Simplified Model

An economist creates a model to explain how individuals choose between working more to earn money for consumption and working less to have more free time. The model only includes two factors: the person's hourly wage and their personal preference for consumption versus free time. Based on this model, the economist argues that if a country's average wages rise, its citizens will universally choose to work fewer hours. Which statement provides the most significant critique of this argument's applicability to the real world?
