01 When can a fall in the output of one firm acquire macroeconomic significance?
Answer and explanation
Correct answer: D. When a similar fall occurs in many firms and total output falls
Explanation: The output of one firm is ordinarily a microeconomic matter. It becomes macroeconomically significant when the decline is widespread across industries or firms and reduces aggregate production, income or employment. The key change is from an isolated individual outcome to an economy-wide aggregate effect.
