Evaluating a Labor Market Model

Critiquing a Simple Market Model's Predictive Power

A standard competitive market model predicts that imposing a per-unit tax on a product will lead to a specific, uniform increase in the market price paid by consumers. However, when a city government imposes a $1 tax on all cups of coffee sold, analysts observe that in neighborhoods with many competing coffee shops, the price to consumers increases by only $0.40, while in neighborhoods with only one or two shops, the price increases by $0.80. Which statement best explains why the simplified model's single prediction doesn't hold true across all these real-world situations?

A standard model of a perfectly competitive market relies on several key assumptions. When these assumptions do not hold true in reality, the model's predictions may be inaccurate. Match each core assumption of this model to the real-world market observation that most directly violates it.

True or False: If a simplified economic model's prediction about a market outcome is proven incorrect by real-world data, it indicates that the model is fundamentally flawed and should be completely discarded for any future analysis.

Evaluating a Trade Model's Labor Prediction

A basic economic model of a competitive labor market predicts that instituting a minimum wage above the existing market-clearing wage will inevitably lead to an increase in unemployment. However, several empirical studies of real-world minimum wage increases in large cities have found negligible effects on overall employment levels. Which of the following statements offers the most robust economic critique of the simple model's failure to predict this outcome?
