<p>这些问题在&lt;微观经济学&gt;书上都有,你随便找一本(例如平狄克等著的)都能看到答案。</p><p>(1)对短期成本函数求导算出边际成本,令其等于边际收益,即价格,这样可以求出产量,从而可以求出利润。</p><p>(2)对边际成本函数再求导,并令其为0,也主是求出边际成本函数的极点,即可求出停产时的产量。</p><p>2、完全竞争市场的四大特征,几乎每本经济学的书上都有明确的讲解,建议你还是去看看书吧</p><p>3、用收入效应和替代效应原理考虑——当老板付给你高工资的时候,你会提供更多的劳动,这就是说供应曲线向上倾斜;但当老板给你的工资非常非常高的时候,你会减少劳动时间,因为你的钱已经够多,喜欢更多的休闲,这时供给曲线就向后弯曲了。</p>

<p><strong>天呀!那么久不看经济学拉,如果不是为拉考试而学经济学的话,还是看看&lt;国富论&gt;,&lt;资本论&gt;吧!原理性的东西更有效用!别被技术的东西给蒙蔽!</strong></p>
