(aggregate demand- aggregate supply), A:Aggregate demand curve shows the total value of the goods and services that are demanded at a, Q:The long-run aggregate supply curve shows that by itself a permanent change in aggregate demand, A:Answer: SRAS, Step 2. SRAS2 Why? Lets first consider an example that involves a shift in supply, then we'll move on to one that involves a shift in demand. Equal-sized increases in both governmentpurchases and taxes, Q4. Just as a price above the equilibrium price will cause a surplus, a price below equilibrium will cause a shortage. LRAS Short-Run Graph The supply curve shows the quantities that sellers will offer for sale at each price during that same period. Correct option: b (in the price level, but not output) A shift in a demand or supply curve changes the equilibrium price and equilibrium quantity for a good or service.
