Which statement best describes microeconomics versus macroeconomics?

• A. Microeconomics analyses economy-wide aggregates like GDP and unemployment.
• B. Micro focuses on individuals/firms; macro analyzes economy-wide aggregates like GDP and unemployment.
• C. Micro studies weather patterns; macro studies population growth.
• D. Macro focuses on consumer behavior; micro focuses on government policy.

Answer: (B)

The scale of analysis is what this question tests. Microeconomics focuses on the behavior of individual decision makers—households and firms—and how their choices determine prices and quantities in specific markets. Macroeconomics looks at the whole economy, using aggregates like gross domestic product and the unemployment rate to understand overall performance and policy effects. Saying that micro analyzes individuals and firms while macro analyzes economy-wide aggregates such as GDP and unemployment matches this fundamental distinction. For example, micro would study how a specific company sets its prices or how a family decides how much to save, while macro would examine why the overall economy grows or why unemployment changes across the entire economy. Other options mix up the focus or bring in topics outside economics entirely, whereas the correct statement clearly assigns the right level of analysis to micro and macro.
