Answer to Question 1

The fact that as the production of one good or service increases, its opportunity cost increases means that the production possibilities frontier will be bowed out. Only if the opportunity cost remained constant as the production of a good increases would the production possibilities frontier be a straight line.

Answer to Question 2

a. When real GDP is 0, aggregate planned expenditure (the sum of C + I + G + X - M) equals 4.5 trillion and unplanned inventory change (the difference between GDP and aggregate planned investment) is -4.5 trillion. When real GDP is 2.5 trillion, aggregate planned expenditure is 5.5 trillion and unplanned inventory change is -3.0 trillion. When real GDP is 5.0 trillion, aggregate planned expenditure is 6.5 trillion and unplanned inventory change is -1.5 trillion. When real GDP is 7.5 trillion, aggregate planned expenditure is 7.5 trillion and unplanned inventory change is 0. And when real GDP is 10 trillion, aggregate planned expenditure is 8.5 trillion and unplanned inventory change is 1.5 trillion.
b. Equilibrium expenditure occurs when unplanned inventory change is 0, or, equivalently, when real GDP equals aggregate planned expenditure. In this problem, equilibrium expenditure occurs when real GDP is 7.5 trillion.
