What Is Aggregate Demand?
Aggregate demand (AD) shows the total amount of goods and services demanded in an economy. This is at a given price level and time. It’s one of the most fundamental concepts in macroeconomics, acting as a thermometer for national economic activity. The formula for AD is:
AD = C+I+G+(X−M)
Each component is crucial in shaping the economy. These components are consumption (C), investment (I), government spending (G) and net exports (X – M). But how do these components work together, and why does aggregate demand matter? Let’s break it down in a way that’s easy to understand.

FAQs About Aggregate Demand
Why does the AD curve slope downward?
The AD curve slopes downward due to the real balance effect, interest rate effect, and net export effect. These factors collectively reduce demand as prices rise.
What factors can shift the AD curve?
Non-price factors like changes in government spending, interest rates, and consumer confidence can shift the AD curve.
How does fiscal policy impact AD?
Fiscal policy, through government spending and taxation, directly influences AD. Increased spending boosts AD, while higher taxes can reduce it.
What role do net exports play in AD?
Net exports (X – M) reflect trade balances. A trade surplus increases AD, while a deficit reduces it.
