 43. If a profit-maximizing firm finds that its marginal revenue exceeds its marginal cost, the firm

A. increase output no matter whether the firm is a price taker or a price searcher.
B. decrease output no matter whether the firm is a price taker or a price searcher.
C. increase output if the firm is a price taker but not necessarily if the firm is a price
searcher.
D. increase output if the firm is a price searcher but not necessarily if the firm is a price
taker.

应该是A  MC=MR决定均衡产量,只要MR大于MC, 就增加产量,从而增加收入.无论是什么性质的企业都只这样

A.

MR=MC always true for profit maximizing entities.

for takers, MR=MC=P

for unregulated searchers, Q is determined as MR=MC, P is charged according to the market Demand Curve

so, what is the final answer?[em01]

很多时间没看过了。。。searcher和taker的定义忘记了

无论什么类型的firm,

mr=mc都是均衡产量条件

如果mr》mc，不增加产量他是傻蛋吧？

画个图就清楚了阿,应该是C

should be C

for the price taker,when MR>MC, it means quantities of outputs are less than the equilibrium point.therefore, the they need to increase the outputs.

for the price searcher, it doesn't matter, since they just set the Quantities by MR=MC

I doubt it.

For price takers, they don't worry about such thing as equilibrium at all and just treat demand is infinite. Why are we confusing individual firm behavor with aggregate product demand/supply equilibrium.

For price searchers, they also care and it will be beneficial for them to increase demand until MR = MC. Note here the question indicates clearly they are currently experiencing MR > MC not that they are already in the state of MR = MC.

是不是c啊，垄断是可以区别定价的。
