The study of the whole economy is called which branch of economics?

• A. Microeconomics
• B. Macroeconomics
• C. Economic System
• D. Markets

Answer: (B)

Macroeconomics focuses on the economy as a whole, looking at large-scale indicators like total output (GDP), the overall price level, unemployment, and economic growth. It also studies how government fiscal and monetary policies influence the entire economy, including inflation and business cycles. This broad, economy-wide perspective is what distinguishes it from other branches. Microeconomics, in contrast, examines individual markets, prices, and the choices of households and firms. An economic system describes how an economy is organized, and markets refer to the mechanisms by which buyers and sellers interact in specific goods and services. Since the question is about studying the entire economy, macroeconomics is the correct fit.
