You are given two equations: P=40−0.2Q [demand equation] P=0.2Q [supply equation] a) On graph paper draw a diagram and plot each equation ( P on the Y-axis and Q on the X-axis); b) Find algebraically the equilibrium price and quantity exchanged. Are the Pe and Qe the same as a) above? c) Calculate the consumer surplus, the producer surplus and total social welfare Now, suppose that the supply equation changes to: P=4+0.2Q d) Using the new supply equation, solve algebraically for the new equilibrium price and quantity exchanged; e) Calculate the consumer surplus, the producer surplus and total social welfare f) What has been the impact on consumer surplus of the shift in the supply?
