Question

can two ppc intersect each other and why?

Answer 1

No . PPC never intersect each other

Answer 2

In Economics, PPC stands for Production Possibility Curve. It is sometimes called as Production possibility frontier.

Yes, it is possible for two Production Possibility Curves to intersect each other.

For example, let us consider there are two goods under production. Say A and B.

If the technology used in production of good A is in appreciation mode and that of good B is in depreciation mode, then the production possibility curves of the two will meet at the point of intersection.
