Note on Shifts in Demand and Supply Curves
Abstract
DESCRIPTIONS of the shifting of demand and supply curves frequently are confusing. Some authors use the words up and down, others vertical and horizontal, while still a third group prefers right and left. Recently one writer' attempted to prove that a shift of the demand curve to the right graphically is the same as a shift upward, but he apparently failed to perceive that the demonstration was necessarily limited to the special case of a negatively sloping straight line.2 Under this particular restriction, clearly a shift upward a shift to the right, a shift downward-=a shift to the left.
