For example, a series of nutrition education classes, open to community members, would not be an example of a community level intervention. Such classes influence individual knowledge, attitudes, and behavior, not the larger social constructs encompassed by this level.
How is underutilization depicted on a production possibilities frontier? It is shown as a point underneath the current production possibility line, and the point shows that not all factor resources are being used and the output of farm and factory goods is less than what is possible
Production possibility frontiers. An opportunity cost will usually arise whenever an economic agent chooses between alternative ways of allocating scarce resources. The opportunity cost of such a decision is the value of the next best alternative use of scarce resources. Opportunity cost can be illustrated by using production possibility frontiers (PPFs) which provide a simple, yet powerful tool to illustrate the effects of making an economic choice. A PPF shows all the possible combinations of two goods, or two options available at one point in time.
