As we have seen, when either the demand or the supply curve shifts, the results are unambiguous; that is, we know what will happen to both equilibrium price and equilibrium quantity, so long as we know whether demand or supply increased or decreased. The event would, however, reduce the quantity supplied at this price, and the supply curve would shift to the left.

We next examine what happens at prices other than the equilibrium price. SRAS, If the shift to the left of the supply curve is greater than that of the demand curve, the equilibrium price will be higher than it was before, as shown in Panel (b). QUANTITY OF OUTPUT Use the graphs to illustrate the new positions of AD, short-run aggregate supply (SRAS), and long-run aggregate supply (LRAS) as well as the new short-run and long-run equilibria resulting from this change.
