What does it imply if a point lies inside the production possibilities frontier?

A point that lies inside the production possibilities frontier (PPF) indicates underutilization of resources. The production possibilities frontier represents the maximum efficient output combinations of two goods that an economy can produce given its resources and technology. When a point is located within the frontier, it shows that the economy is not utilizing all available resources effectively; some resources may be idle, or production may be occurring inefficiently.

In contrast, a point on the frontier demonstrates efficient resource allocation, as it signifies that all resources are being used to their fullest potential without waste. Points outside the PPF are unattainable with the current resources and technology. Thus, the understanding of points in relation to the PPF is essential for assessing economic efficiency and resource utilization.
