Final answer:
Aggregate Demand can shift due to factors such as consumer confidence, interest rates, government spending cuts, and expansionary monetary policy.
Step-by-step explanation:
Aggregate Demand (AD) can shift due to various factors. For example:
- An increase in consumer confidence or business confidence can shift AD to the right, leading to a higher quantity of output and price level.
- Higher interest rates can shift AD to the left, resulting in a lower quantity of output and price level.
- Government spending cuts can also shift AD to the left, causing a decrease in both output and price level.
- Expansionary monetary policy can shift AD to the right, leading to an increase in output and price level.
