B) US GDP will fall

D) US real GDP will rise

Answer 1

9) Answer: $350

For the open economy to achieve equilibrium the domestic output should be equal to AE closed economy.

10) Answer: become steeper

Negative net exports or almost zero will have a contractionary effect as the net exports will decrease aggregate expenditure beyond what they will decrease.

13) Answer: The economy is at sustainable full employment level

When economy is operating above equllibrium point it means that the economy is producing goods and services at a higher state than its level which means it is having full employment. Only when there is full employment in economy than only there will be high production of goods and services.

15) Answer: US GDP will fall

GDP = C+I+G+NX

NX = Exports - Imports

So when imports are increasing than exports than there will be a negative value in net exports which means the GDP value will fall.

Thus US GDP will fall.
