Deadweight loss 净损失

(1)如果P=60美元/桶，天然气的自由市场价格是多少？如果价格上限为3美元/千立方英尺，无谓损失多大？

(2)石油价格应为多少，才会得到3美元的天然气自由市场价格？

In Example 9. 1 (page 290), we calculated the gains and losses from price controls on natural gas and found that there was a deadweight loss of $ 5.68 billion. This calculation was based on a price of oil of $50 per barrel.

a. If the price of oil were $ 60 per barrel，what would be the free - market price of gas？ How large a deadweight loss would result if the maximum allowable price of natural gas were $3. 00 per thousand cubic feet？

b. What price of oil would yield a free - market price of natural gas of $3. 00？

A.Maximize total surplus

B.Generate underproduction

C.Minimize deadweight loss

(1)国内价格将是多少？

(2)国内生产者和消费者的损益各为多少？

(3)对无谓损失和国外生产者会产生什么影响？

Example 9.5 (page 308 ) describes the effects of the sugar quota. In 2005 , imports were limited to 5.3 billion pounds , which pushed the domestic price to 27 cents per pound. Suppose imports were expanded to 10 billion pounds.

a What would be the new U. S. domestic price？

b. How much would consumers gain and domestic producers lose？

c. What would be the effect on deadweight loss and foreign producers？
