4. The table below shows aggregate demand and aggregate supply schedules in hypothetical economy. Aggregate Demand and Aggregate Supply Schedules Real GDP (ADO) (AD1) (ASO) (AS1) Price Level (2007 = 100) (2007 $ billions) 140 190 240 270 320 130 210 260 260 310 120 230 280 230 280 110 250 300 200 250 100 270 320 160 210 a. Draw a graph showing AD., AD,, AS., and AS,. Plot only the endpoints of the two aggregate demand curves and all five points for each of the two aggregate sup- ply curves. b. If initially AD. and AS are the relevant schedules, what are the equilibrium price level and real output? What happens if the price level is 140? 110? c. If aggregate demand shifts from AD. to AD, while aggregate supply remains at AS, what are the new equilibrium price level and real output? Describe this change in aggregate demand. d. If aggregate supply shifts from AS. to AS, while aggregate demand remains at AD, what are the new equilibrium price level and real output? Describe this change in aggregate supply. Is it a short-run or long-run change
