Microeconomics vs. Macroeconomics Focus

Steps:

• Recall microeconomics studies individual agents like consumers and firms, analyzing choices under scarcity.
• Identify choices A, B, D as firm-level (costs/revenues), consumer decisions, and labor market specifics (wages), all micro topics.
• Recognize choice C involves aggregate economy-wide policies, fitting macroeconomics.
• Confirm by definition: micro examines partial equilibrium; macro looks at overall growth.

Why C is correct:

• Economic growth policies target national output and employment aggregates, a core macroeconomic area per standard definitions like those in Mankiw's Principles of Economics.

Why the others are wrong:

• A: Firm costs and revenues are microeconomic profit maximization analyses.
• B: Consumer behavior involves utility maximization, a foundational micro concept.
• D: Wages by occupation reflect labor supply/demand in specific markets, microeconomic.

Final answer: C
