Assume that your classmate suggested that both graphs represent constant opportunity costs because movement from combinations A to B, B to C, and C to D stays the same for each economy. Explain why this is incorrect.

It should be noted that it's incorrect because movement of combination being presented in a equal way doesn't imply a constant opportunity cost.

A constant opportunity cost simply occurs when the opportunity cost is the same when the individual increases the production of a good.

In this case, the classmate suggested that both graphs represent constant opportunity costs because movement from combinations A to B, B to C, and C to D stays the same for each economy. This doesn't mean that there is a constant opportunity cost.

The movement of the combinations, explained by your classmate, is presented in an equal way, which does not represent an opportunity cost. In order to be able to perceive a constant opportunity cost, the combinations should present different values, and the choice of one of them, would cause the loss of opportunity to submit to the results that would be obtained with the choice of the others. However, as all combinations are the same, choosing any one would give the same results.

Explanation:

A constant opportunity cost refers to the presentation of elements in a business that would happen differently from each other and that would present different profitable results in a constant and extended way, showing the value and benefits that each one has individually.
