What is the name of the economic discipline that studies entire economies, including inflation, unemployment, and GDP?

• A. Microeconomics
• B. International economics
• C. Behavioral economics
• D. Macroeconomics

Answer: (D)

Macroeconomics is the study of the economy as a whole, focusing on broad indicators like inflation, unemployment, and GDP. These aggregates capture overall price levels, the health of the labor market, and total economic output, which are the core concerns when analyzing how an entire economy performs and responds to policy changes. Microeconomics, by contrast, looks at individual markets and the choices of households and firms; international economics examines trade and cross-border finance; and behavioral economics explores how psychology affects economic decisions. Since the question centers on broad economic performance across the whole economy, the discipline that fits best is macroeconomics.
