In economics, what curve shows the maximum combinations of two goods an economy can produce with available resources?

In economics, the production possibility frontier shows the maximum combinations of two goods an economy can produce with available resources and technology.

Points on the frontier represent productive efficiency under the model’s assumptions. Points inside it indicate that resources are underused or allocated inefficiently, while points outside it are unattainable with current resources and technology. Producing more of one good generally requires sacrificing some of the other.

The frontier is especially useful for illustrating scarcity, choice, opportunity cost, and economic growth. Its slope at a point represents the opportunity cost of shifting production toward one good. A bowed-out shape commonly reflects increasing opportunity costs when resources are specialized.

The frontier is a simplified model rather than a complete national production plan. It often examines two goods, although real economies produce millions of products. More labor, capital, natural resources, or productive technology can shift the frontier outward.
