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
Since the production possibilities frontier represents all of the points where all resources are being used efficiently, it must be the case that this economy has to produce fewer guns if it wants to produce more butter, and vice versa. The slope of the production possibilities frontier represents the magnitude of this tradeoff. For example, in moving from the top left point to the next point down the curve, the economy has to give up production of 10 guns if it wants to produce 100 more pounds of butter. 1  Not coincidentally, the average slope of the PPF over this region is (190-200)/(100-0) = -10/100, or -1/10.
