Answer:
A. Interest rates rise.
C. There is an economic boom overseas that raises the incomes of foreign households.
Explanation:
Option A - It is correct because if the interest rate increases, consumer spending will decline. Therefore, the aggregate demand curve will shift to the left.
Option B - If the government reduces the personal income tax, the consumers will spend more, it will lead the aggregate demand to the right. So, it is wrong.
Option C - Foreign households' income will lead to more savings. Therefore, spending will decline. So, it is the correct statement.
Option D - It is incorrect because corporate profit tax will not consider in the aggregate demand.
