※ 引述《betray911015 (回頭太難)》之銘言： : 1. A multimarket price discriminator sells its product in : Florida for three times the price it sets in New York. : Assuming the firm faces the same constant marginal cost : in each market and the price elasticity of demand in : New York is -2.0, the demand in Florida : a. has an elasticity of -6.0 : b. is more price elastic than the demand in New York : c. has an elasticity of -0.2 : d. has an elasticity of -0.67 : 我的想法:因為是獨佔市場，不是彈性在大於一都成立嗎?? 你到底知不知道題目再考你什麼? : 2. Can a firm be a natural monopoly if it has a U-shaped : average cost curve? Why or why not? : 我的想法: 我覺得是不能，因為自然獨佔廠商的平均成本不是呈 : 遞減嗎?但答案說可以，為什麼?? 平均成本遞減是自然獨佔的充分條件，但非必要條件 就算AC curve 呈現U型 只要市場需求量不超過U型的最低點 則該廠商仍然是自然獨佔 同學 書要念通 --
