Re: [請益] 個經題目
※ 引述《vivayet (小小明)》之銘言：

: the government imposes rent control at p=$300/month. suppose demand grows
: in the market to P=1400-Q.
: a.How is excess demand affected by the grownth in demand for apartments?
: b. At what price would the government have to set the rent control to
: keep excess demand at the same level as prior to growth in demand?
: 想請問一下Ａ答案８００和Ｂ答案是４００嗎
: 因為Ｂ答案比較不確定 同學算的有２個版本
: ４００跟２００
b.答案我算出的限價是400
Qd=1400-P
Qs=P
Qd-Qs=1400-2P=600(需求成長之前的ED)
所以Pc=400
若有錯誤
請指教更正
謝謝
