Question

1.

Given the table above and assume that guns are represented on the Y axis and butter on the X axis. Which of the following question is true.

The opportunity cost is constant at 1 Butter for every 10 guns.

The opportunity cost of increasing butter from 4 units to 5 units is 5 units of guns.

The opportunity cost of increasing butter from 4 units to 5 units is 50 units of guns.

This PPF is a straight line constant cost model.

2.

Given the table above and assume that guns are represented on the Y axis and butter on the X axis. Which of the following question is true.

The opportunity cost of moving from 2 butter to 3 butter is 15 units of guns.

The opportunity cost of increasing butter from 4 units to 5 units is 5 units of guns.

This PPF is a straight line constant cost model.

The opportunity cost is constant at 1 Butter for every 10 guns.

3.

Given the table above and assume that guns are represented on the Y axis and butter on the X axis. Which of the following question is true.

The opportunity cost is constant at 1 Butter for every 10 guns.

Increasing gun production has no opportunity cost.

This PPF is a straight line constant cost model.

This model is a bowed PPF representing the law of increasing cost.

Butter Guns 0 100 1 98 2 90 3 75 4 50 5 0

Explanation / Answer

(1) Option (3)

Opportunity cost of butter = Change in quantity of guns / Change in quantity of butter = (50 - 0) / (5 - 4)

= 50/1 = 50

(2) Option (1)

Opportunity cost of butter = Change in quantity of guns / Change in quantity of butter = (90 - 75)/(3 - 2)

= 15/1 = 15

(3) Option (4)

As more units of butter are produced, units of guns to be given up is increasing, reflecting increasing opportunity cost and a bowed-out PPF.
