things affect aggregate demand?
Answers
(AD) is the total amount of goods and services consumers are willing to purchase in a given economy and during a certain period. Sometimes aggregate demand changes in a way that alters its relationship with aggregate supply (AS), and this is called a "shift."
Since modern economists calculate aggregate demand using a specific formula, shifts result from changes in the value of the formula's input variables: consumer spending, investment spending, government spending, exports, and imports.
When these other factors change, they cause a shift in the entire AD curve and are sometimes called aggregate demand shifters. These aggregate demand shifters include anything that will influence the levels of Consumption, Investment, Government Spending, or Net Exports OTHER THAN changes in the price level.
