(A movement along the curve is described as a "change in the quantity demanded" to distinguish it from a "change in demand", that is, a shift of the curve.) The increase in demand has caused an increase in (equilibrium) quantity. The increase in demand could come from changing tastes and fashions, incomes, price changes in complementary and ...
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.

Example: A lowering of the federal funds target would shift the MP curve to the right, resulting in a lower interest rate, and higher inflation. This lower interest rate results in a downward movement along the IS curve, increasing output.
Firms hire them because they see the inflation as allowing higher profits for given nominal wages. This is a movement along the Phillips curve as with change A. Eventually, workers discover that real wages have fallen, so they push for higher money wages. This causes the Phillips curve to shift upward and to the right, as with B. Some research ...
The demand curve would therefore shift to the right and real GDP would be growing above potential. The inflation adjustment line would then shift upward (reflecting an increase in the inflation rate) causing a movement along the new demand curve until real GDP was equal to potential.
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]
A shift in the IS curve along a relatively flat LM curve can increase output substantially with little change in the interest rate. On the other hand, a rightward shift in the IS curve along a vertical LM curve will lead to higher interest rates, but no change in output (this case represents the "Treasury view").
The aggregate demand curve is plotted with real output on the horizontal axis and the price level on the vertical axis. While it is theorized to be downward sloping, the Sonnenschein–Mantel–Debreu results show that the slope of the curve cannot be mathematically derived from assumptions about individual rational behavior.
