Suppose that foreigners had reduced confidence in U. S. financial institutions and believed that privately issued U. S. bonds were more likely to be defaulted on. U. S. net exports would a. rise which by itself would increase aggregate demand. b. rise which by itself would decrease aggregate demand. c. fall which by itself would decrease aggregate demand. d. fall which by itself would increase aggregate demand.

Option C, fall which by itself would decrease aggregate demand, is the right answer.

Explanation:

Option C is correct because the reduction in the confidence level in U.S financial institutions will decrease the U.S net export. Moreover, if the foreigner feels insecure about the U.S bonds then this insecurity will induce them to demand less. Therefore, when the net export decreases the aggregate demand will also fall. Thus we can say option C is right.
