※ 引述《vivayet (小小明)》之铭言:
: the demand for apartments is P=1200-Q while the supply is p=q units.
: 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?
: 想请问一下A答案800和B答案是400吗
: 因为B答案比较不确定 同学算的有2个版本
: 400跟200
b.答案我算出的限价是400
Qd=1400-P
Qs=P
Qd-Qs=1400-2P=600(需求成长之前的ED)
所以Pc=400
若有错误
请指教更正
谢谢
