CHANGE IN AGGREGATE EXPENDITURES: The movement along an aggregate demand curve caused by a change in the price level. This should be contrasted directly with a change in aggregate demand. You might also want to review the terms change in quantity demanded and change in demand, as well.

PRODUCTION POSSIBILITIES CURVE A curve that illustrates the production possibilities of an economy--the alternative combinations of two goods that an economy can produce with given resources and technology. A production possibilities curve (PPC) represents the boundary or frontier of the economy's production capabilities, hence it is also frequently termed a production possibilities frontier (PPF).

The law of increasing opportunity cost is what gives the curve its distinctive convex shape.
