The foreign purchases, interest rate, and real-balances effects explain why the A. Aggregate demand curve is downward-sloping.

It should be noted that the aggregate demand curve is downward-sloping due to the fact that a decrease in output will lead to an increase in price.

Also, a reduction or an increase in the autonomous spending can shift the aggregate demand curve. When the foreign demand for domestic good falls, then the foreign spending decreases.
