This would cause the entire demand curve to shift changing the equilibrium price and quantity. Note in the diagram that the shift of the demand curve, by causing a new equilibrium price to emerge, resulted in movement along the supply curve from the point (Q 1, P 1) to the point (Q 2, P 2).
Movements along the curve occur only if there is a change in quantity supplied caused by a change in the good's own price. [10] A shift in the supply curve, referred to as a change in supply, occurs only if a non-price determinant of supply changes. [10]
The supply and demand model describes how prices vary as a result of a balance between product availability and demand. The graph depicts an increase (that is, right-shift) in demand from D 1 to D 2 along with the consequent increase in price and quantity required to reach a new equilibrium point on the supply curve (S).
Movement "along the demand curve" refers to how the quantity demanded changes when the price changes. Shift of the demand curve as a whole occurs when a factor other than price causes the price curve itself to translate along the x-axis; this may be associated with an advertising campaign or perceived change in the quality of the good.

The price elasticity of supply measures how the amount of a good that a supplier wishes to supply changes in response to a change in price. [14] In a manner analogous to the price elasticity of demand, it captures the extent of horizontal movement along the supply curve relative to the extent of vertical movement. If supply elasticity is zero ...
Thus, a supply curve with steeper slope (bigger dP/dQ and thus smaller dQ/dP) is less elastic, for given P and Q. Along a linear supply curve such as Q = a + b P the slope is constant (at 1/b) but the elasticity is b(P/Q), so the elasticity rises with greater P both from the direct effect and the increase in Q(P).
During an otherwise sterling performance in Tuesday night's debate, Sen. J.D. Vance (R–Ohio) made one telling misstep: He admitted that he actually does understand how costs along a supply chain ...
Aggregate demand is expressed contingent upon a fixed level of the nominal money supply. There are many factors that can shift the AD curve. Rightward shifts result from increases in the money supply, in government expenditure, or in autonomous components of investment or consumption spending, or from decreases in taxes.
