In a perfect competition market, every firm has the same long run total cost
function as
TC=q平方+16 and the demand function of the market is Q=1200-20P
Please answer the
following questions :
(a) If the government allow only 200 firms to supply the market in the long
run, what are the
market equilibrium price, quantities each firm produced and profit each firm
made in the long
run?
(b) If the government allows firms to free enter or exit the market, what are
the market equilibrium
price, quantities each firm produced and the number of the firms in the long
run?
第一題我算出來 q=5 Q=1000 P=10 每家廠商利潤9
第二題是我卡住的地方 q跟p跟廠商家數都變動 Q總產量應該不會也變動吧
有三個變數實在不知道怎麼算
徵求高手解答
謝謝
