※ 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??
假設 New York 的定價是 p, 則 Florida 的定價是 3p
獨占兩市場會滿足 MR1 = MR2 = MC
即p1*(1+1/Ed1) = p2*(1+1/Ed2) = MC (Ed1跟Ed2是第一個跟第二個市場的彈性)
題目的數字帶入得到 p*(1-1/2) = 3p*(1+1/Ed) 解Ed
得到Ed為-1.2
你的c選項打錯了, 因為我手邊有一樣的題目, c選項應該是-1.2

2F:推 happypool:選項有問題沒錯 不過這一題應該不用算 2.0>Ed>1.0 01/16 22:06
3F:→ happypool:只要知道Florida Ed 小於 New York Ed 且獨佔Ed>1即可 01/16 22:09
4F:推 estupid:佛羅里達相對價格高->彈性較小 且獨占在彈性大於1處生產 01/16 22:14
