Question

Why is the shape of the production possibilities frontier (PPF) often curved instead of straight? Because the production possibilities frontier is based on the productive capabilites, and of a nation overall, rather than the productive capacity of an individual. Typically, some resources are better suited for producing one good than another, which means that there are diminishing returns when moving such resources away from producing what they are best suited for. The productive efficiency of an economy decreases as it moves from left to right along the PPF. To take a potential sunk cost into account, the PPF is curved to distribute the burden of the sunk cost based on allocative effieciency.

Answer 1

The correct answer is the second statement.

Step-by-step explanation:

A production possibility frontier shows the maximum possible combinations of two goods that can be produced using the given resources. This frontier is concave to the origin. The curve shape of this frontier is because of increasing marginal opportunity cost.

We have limited resources that serve alternative uses. To increase the production of one commodity we need to decrease the production of the other. but the resources are not perfectly substitutable between these two goods. So when we increase the production of one good the marginal opportunity cost of the giving up the alternative goes on increasing.
