CHANGE IN QUANTITY DEMANDED: The movement along a demand curve caused by a change in the price of the good. This should be contrasted directly with a change in demand. You might also want to review the terms change in quantity supplied and change in supply, as well. A change in quantity demanded means that we have identified a NEW quantity on the existing demand curve. In contrast, a change in demand means that we have changed, moved, or shifted, the entire demand curve, the whole range of prices and quantities has changed.

Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.
