A Short Run Aggregate Supply Curve Shows the
A supply curve tells us the quantity that will be produced at each price and that is what the firms marginal cost curve tells us. This is illustrated with the series of graphs below.

Such a movement is called a change in quantity supplied.
. The supply curve for coffee in Figure 38 A Supply Schedule and a Supply Curve shows graphically the values given in the supply schedule. Initially the economy is operating in a long-run equilibrium where the short-run aggregate supply SRAS LRAS and aggregate demand AD are in equilibrium and the resulting price level is PL 1 and Q LR is. As is the case with a change in quantity demanded a change in quantity supplied does.
The firms supply curve in the short run is its marginal cost curve for prices above the average variable cost. The SRAS curve is also drawn to reflect some variables such as the nominal wage rate. This nominal wage rate is fixed in the short run so a rise in price implies higher profit potential to justify the increase in production.
Thus we find that while the short-run supply curve of the industry always slopes upwards to the right the long-run supply curve may be a horizontal straight line sloping upwards or sloping downwards depending upon the fact whether the industry in question is a constant cost industry increasing cost industry or decreasing cost industry. This means it goes upward sloping rather than full vertical. The movement from the original equilibrium of E 0 to the new equilibrium of E 1 will bring a nasty set of effects.
Reduced GDP or recession higher unemployment because the economy is now further away from. In the short run the aggregate supply curve reacts to the price level. But the long-run upward sloping curve is.
This differs in the. The economy has returned to the long-run aggregate supply but at a lower price level. The interactive graph below Figure 2 shows the aggregate supply curve shifting to the left from SRAS 0 to SRAS 1 causing the equilibrium to move from E 0 to E 1.
A change in price causes a movement along the supply curve.
