Distinguishing Economic Models from Anecdotes

An economist observes that their personal grocery bills have increased significantly over the past year, while their salary has remained the same. Based solely on this personal experience, they conclude that the entire country is experiencing a decline in the purchasing power of wages. Is this conclusion considered an empirically validated economic finding?

A team of economists develops a new theoretical model suggesting that an unexpected increase in global shipping costs will lead to a decrease in the average household's purchasing power within six months. Arrange the following steps in the most logical order to empirically test this model's prediction.

Match each term related to the validation of economic theories with its correct description.

An economist's model predicts that a 10% increase in a country's minimum wage will cause a 2% decrease in employment for low-skilled workers. After such a wage hike occurs, the economist finds a single large company that laid off exactly 2% of its workforce and claims this event proves the model's validity. Which statement best evaluates the economist's claim?
