    纠结的 m. e.

    当初我纠结的微经又来纠结我哥哥了

    而且纠结的部分都一样,可怕的血缘啊!
     
    虽然这两天我脑子就转了这么一下
    但和哥哥讨论题目很开心地说=)

    从书上给的图像上来看,两个图像应该是在ATC图像的顶点处相交,就像我刚才画给你的那样子,我就是想知道为什么
     

     Yifan♡China says:
    哦,这个是有解释的
     

     (叨叨)纠结的M.E.ωA New Phase Of Lifeω says:
    我们的书上没有解释
    所以我只能分段理解,之前两个同降的好理解,边际成本降低,平均成本也降低,但中间一段我就不明白了,边际成本升高了,平均成本还在降低是怎么回事?

    when MC is less than AC, AC is decreasing, and when MC exceeds AC, AC is increasing
     

     (叨叨)纠结的M.E.ωA New Phase Of Lifeω says:
    这是现象
     

     Yifan♡China says:
    其实解释了原因

     Yifan♡China says:
    MC比AC小的时候,代表多生产一个单位是合算的
    当你多生产一个单位商品所需要的成本MC,超过了现在生产的单位成本AC
    就说明现在生产的单位成本达到最低的了
     

     (叨叨)纠结的M.E.ωA New Phase Of Lifeω says:
    哦,,,我终于想通了
    在平均成本达到最低之前,边际成本即使增加了,生产成本依然是会降低的,对不?
     

     Yifan♡China says:
    我当时觉得很难想,后来书上举了GPA的例子,就说,某单次考了最高,你那时的平均GPA也必然会最高
     

     (叨叨)纠结的M.E.ωA New Phase Of Lifeω says:
    只要边际成本是低于平均的,即使不是最低,也是会降低平均成本的

     Yifan♡China says:
    没错没错!!!但为什么MC会在AC前达到低点,可以看刚才的表格去想
    就像GPA...虽然平均GPA在考了4.0的时候达到最高,但画到坐标系里面,以学期为X轴,平均GPA是要在学期一二之间
    而4.0是在第二学期,所以你的绝对GPA和平均GPA不在同一个时刻达到最高
     
     (叨叨)纠结的M.E.ωA New Phase Of Lifeω says:
    那个我懂的,,因为除数不一样,一个除以变量一个是除整体
    搞定了,哈哈,好开心
     
     Yifan♡China says:
    嗯,至少一年不会忘记了哈哈哈

     
     (叨叨)纠结的M.E.ωA New Phase Of Lifeω says:
    唔,我继续了,,微观还真难哦
     
     Yifan♡China says:
    痛苦的过程...你继续吧!!

     
     (叨叨)纠结的M.E.ωA New Phase Of Lifeω says:
    痛并快乐着

     
     Yifan♡China says:
    多借点书,有的上面有具体例子,会减少痛苦的感觉...不说了
