Riverton PPF — Agriculture and Machinery

This production possibilities frontier uses Riverton's choices between farm equipment and grain output to explain scarcity. The bowed frontier shows the maximum output combinations available with current resources and technology. Point A is on the frontier, so it represents productive efficiency. Point B lies inside it and represents unused resources or inefficient production. Point C is beyond it and cannot be reached with the current capacity. Moving along the frontier means producing more of one output and less of the other. An outward shift would represent more resources or improved technology, such as irrigation, training or new machinery and trained workers.
