4. PER-UNIT GASOLINE TAX: Suppose that gallons of gasoline are sold in a competitive market. In the very short run, assume supply is given by PS = QS while demand could take any of the three forms below. For each type of demand, draw the free market diagram and find P* and Q*. On your diagram, impose a $1 per-gallon gas tax, find prices PPAID and PRECD, and then indicate consumer surplus (CS), producer surplus (PS), tax revenue (TR), and deadweight loss (DWL) on your diagram. TIP: Some welfare measures may be zero! You needn't calculate the areas. a) "Gotta get to work ASAP!” Demand is given by Qd = 30 for prices at or below $5, but Qd = 0 for P> $5. b) "Hmmm, there may alternatives to driving." Demand is given by Pd= 6 - (1/10)Qd. c) "No way - I'll bike instead!" Demand is given by Qd = 0 for prices above $3, and then ANY Qd is possible at a price of $3.
