What is a key component of aggregate demand?

• A. Government revenue
• B. Income levels
• C. Household consumption
• D. Deflation

Answer: (C)

Household consumption is a key component of aggregate demand because it represents the total expenditure by households on goods and services within an economy. This consumption is driven by various factors, including income levels, consumer confidence, and interest rates. When household consumption increases, it leads to higher demand for goods and services, which can stimulate production and economic growth. Since consumption accounts for a significant portion of overall economic activity, it is often viewed as a primary driver of aggregate demand, alongside other components such as investment, government spending, and net exports. Understanding the role of household consumption helps in grasping how changes in consumer behavior can influence economic trends and policy decisions.
