Which statement best describes the difference between microeconomics and macroeconomics, with a business example?

• A. Macroeconomics studies economy-wide aggregates; example: impact of interest rate changes on capital investment.
• B. Macroeconomics studies individual markets, prices, and behaviors; example: pricing decisions based on demand.
• C. Microeconomics studies individual markets, prices, and behaviors; example: pricing decisions based on demand.
• D. Microeconomics studies economy-wide aggregates; example: changes in interest rates affecting total investment.

Answer: (C)

Microeconomics focuses on individual markets, prices, and the decisions of firms and consumers. In a business setting, this means analyzing how a company sets prices for a specific product based on demand, competition, and costs in that market. That’s why describing micro as studying individual markets and pricing decisions grounded in demand is the best fit. Macroeconomics, on the other hand, looks at the whole economy—aggregates like GDP, unemployment, and inflation—and how policy changes, such as shifts in interest rates, influence total investment. The other options mix micro and macro roles, so this choice most clearly captures the distinction with a concrete business example.
