Using an aggregate demand graph, illustrate the impact of an increase in the interest rate
What will be an ideal response?
The increase in the interest rate will cause consumption expenditures and investment expenditures to decline. This will result in a parallel leftward shift in the aggregate demand curve. We start on the curve AD1 and the increase in the interest rate will move us to AD2. At the price level P1, the demand for real GDP declines from Y1 to Y2.
