How will the aggregate demand curve change when interest rates fall

A leftward shift in the aggregate demand curve would indicate a decrease in overall demand for goods and services. This scenario typically occurs in response to higher interest rates, which discourage borrowing and spending. Therefore, a fall in interest rates cannot cause such a shift.

An outward bowing of the aggregate demand curve would suggest that the rate of increase in demand accelerates as prices rise, which is not a typical response to falling interest rates. Instead, interest rate reductions generally lead to a more straightforward rightward shift in the curve, rather than altering its shape.

An inward bowing of the aggregate demand curve would imply diminishing increases in demand as prices rise, which does not accurately reflect the impact of lower interest rates. This shape change would not occur; instead, the aggregate demand curve shifts rightward with increased demand due to cheaper borrowing.
