Movement along the curve
Definition. A movement along the curve is the change in the quantity demanded or quantity supplied of a good that results solely from a change in its own price, with all other influences held constant. It traces a path along an existing demand or supply curve.
It is distinct from a shift of the whole curve, which is caused by a change in a non price determinant such as income, tastes or input costs. A movement along the curve is sometimes called a change in quantity demanded or supplied.
