What is the relationship between the aggregate planned expenditure curve and the aggregate demand curve? Explain the relationshi
What will be an ideal response?
The aggregate demand curve is derived using the aggregate planned expenditure curve. The aggregate planned expenditure curve shows how equilibrium expenditure changes when the price level changes. Then the aggregate demand curve plots the price level and the resulting equilibrium expenditure to illustrate how equilibrium expenditure (and hence the aggregate quantity of real GDP demanded) depends on the price level.
