                  of government intervention.
                  b) Suppose the government imposes a price ceiling of $3       F

                        What area represents consumer surplus?
                        What area represents the largest producer surplus possible under the policy?

                        What area represents the smallest producer surplus possible under the policy?
                        What area represents government receipts?
