In constructing models, economists:

• A. always include every real-world detail to ensure accuracy
• B. avoid using any assumptions to prevent bias
• C. make simplifying assumptions to focus on key relationships
• D. rely solely on normative statements to guide their analysis

Answer: (C)

Verified step by step guidance

1. Understand that economic models are simplified representations of reality designed to highlight essential relationships and mechanisms.
2. Recognize that including every real-world detail would make models overly complex and less useful for analysis.
3. Know that assumptions are necessary in modeling to reduce complexity and focus on key variables and their interactions.
4. Distinguish between positive statements (descriptive, testable) and normative statements (value-based, prescriptive); models primarily rely on positive statements.
5. Conclude that economists make simplifying assumptions to create manageable models that help explain and predict economic behavior effectively.
