Explanation / Answer

GDP is the value of Y.

Aggregate expenditure (AE) = C + I + G - NX

At GDP it means Y = 13600

AE = 250 + 0.8 (13600) + 1250 + 2000 -100

AE = 14280.

Unplanned changes in inventory is difference between GDP and AE = 14280 - 13600 = 680

Here the aggregate expenditure is more than Y it means the unplanned change in inventory is that the inventory is fall by $680 so we use the minus sign and unplanned change in inventory is -680

At GDP or Y = 20,400

AE = 250 + 0.8(20,400) + 1250 + 2000 -100 = 19,720.

So the unplanned change in inventory is 20,400 - 19720 = 680.

But here the Y is great than aggregate expenditure it means that the inventory will rise by 680.

GDP Aggregate expenditure Unplanned change in inventory $13600 $14280 -680 $20400 $19720 680
