The demand and supply of ethanol are given by QD 8,000 2,000P and QS = 1,000P - 1,000, where P is price per gallon and Q measures gallons per minute. If the government subsidizes ethanol at $0.30 per gallon, what is the deadweight loss? A) $30 B) $7,800 C) S119 D)$440

Federal excise taxes on gasoline vary widely across the developed world. The United States has the lowest taxes at USD $0.40 per gallon (or £0.07 per liter), Canada has taxes of $0.60 per gallon, Japan and much of Europe is $2.00 per gallon, while Britain has the highest tax at $2.83 a gallon or £0.5 per liter. If gasoline taxes are intended to reduce the time losses from road congestion in urban environments and gasoline pre-tax costs about £0.40 per liter, why might the optimal tax in Canada be 50 percent higher than in the United States? What would be an explanation for why adjacent countries would have such different estimates of the price elasticity of demand for auto driving?16

What would the gasoline price elasticity of supply mean to UPS or FedEx?

Under which circumstances does line tax burden fall entirely on consumers?
