MR =P(1-1/|E|)如何记忆这个公式呢

NO.PZ2018062003000066

问题如下:

Being a monopoly in the market, Googge,Inc. recently carrys out its market study and finds that the price elasticity of demand is 1.8. If the marginal cost is $30 and the average cost is $50, its price is most likely to be:

选项:

A.

$30.

B.

$50.

C.

$68.

解释:

C is correct

When MR = MC, the firm can achieve maximized profits. Because MR =P(1-1/|E|) we can draw the equation:

$30 = P[1 – (1/1.8)] = P × 0.444

P = $68

考题:利润最大化

解析:本题直接考察利润最大化,

直接套用公式,MR =P(1-1/|E|),代入数据得:

$30 = P[1 – (1/1.8)] = P × 0.444,反解得到P

P = $68

MR =P(1-1/|E|)如何记忆这个公式呢

嗨,从没放弃的小努力你好:


同学你好,mr=p*(1-1/ep)其实是我们推导得出的,如果同学不能记住公式也可以记推导过程。

mr=d(revenue)/dq,增加一单位产量对于总收入的影响。

revenue=p*q

而价格和数量的弹性是-dp/dq 这里有个负号

所以mr=p*dq/dq+q*(dp/dq)=p+q*(dp/dq)=p(1-1/ep)

所以是-1/ep


----------------------------------------------
虽然现在很辛苦,但努力过的感觉真的很好,加油!
