Question

Giving reason comment on the shape of Production Possibilities curve based on the following schedule :

Good X (units Good Y (units)
0 30
1 27
2 21
3 12
4 0

 

Solution

Marginal opportunity cost is as follows:

Good X
(units)
Good Y
(units)

MOC = `"ΔY"/"ΔX"`

0 30 -
1 27 3/1 = 3
2 21 6/1 = 6
3 12 9/1 = 9
4 0 12/1 = 12

The above schedule clearly states that the production of Good X increases from Unit 1 to  Unit 2, and correspondingly, the units of Good Y forgone is 3. While the production of Good  X increases from Unit 2 to Unit 3, 6 units of Good Y are forgone. With each additional unit of production of Good X, the amount of Good Y to be forgone increases. So, because of increasing opportunity cost, the production possibility curve (PPC) is concave to the origin.
