In the presubsidy market for gasoline, the supply curve S₁ intersects with the demand curve D at the equilibrium price P₁ and equilibrium quantity Q₁. The consumer surplus is A + B + C, and the producer surplus is F + G + J. After a government subsidy is put in place, the supply curve shifts down by the amount of the subsidy, P_s – P_b, to S₂. At the equilibrium, the quantity increases to Q₂, the price facing suppliers is P_s, and the price facing buyers is P_b. Consumer surplus is now A +B + C + F + G + H, and producer surplus is F + G + J + B + C + D. The cost of the subsidy is B + C + D + E + F + G + H + I, and the deadweight loss is E + I. Therefore, the costs associated with the subsidy are larger than the sum of the benefits to producers and consumers.
