Which of the following statements about economic models is NOT correct?

• A. Economic models always provide perfectly accurate predictions of real-world outcomes.

• D. Economic models can be used for both positive and normative analysis.

Answer: (A)

Verified step by step guidance

1. Step 1: Understand what an economic model is. Economic models are simplified representations of reality designed to analyze economic phenomena by focusing on key variables and relationships.
2. Step 2: Recognize the role of assumptions in economic models. Assumptions help to isolate the most relevant factors by simplifying complex real-world situations, making the model easier to analyze and understand.
3. Step 3: Differentiate between positive and normative analysis. Economic models can be used for positive analysis (describing and predicting economic behavior) and normative analysis (making value judgments about economic policies).
4. Step 4: Evaluate the statement about accuracy. Economic models do not always provide perfectly accurate predictions because they simplify reality and rely on assumptions that may not hold in every situation.
5. Step 5: Identify the incorrect statement. The statement claiming that economic models always provide perfectly accurate predictions is NOT correct, as models are tools for understanding and approximating reality, not exact forecasts.
