<p>以下是 Mankiw  PRINCIPELS OF ECONOMICS   326页的一句原话:</p><p>if the high monopoly price did not discourage some consumers from buying the good, it would raise producer surplus by exactly the amount it reduced consumer surplus,leaving total surplus the same as could be achieved by benevolent social planner.</p><p>这句话该怎么理解,我怎么感觉不对呀.我理解是如果producer surplus raised  和consumer surplus reduced都一样了,那deadweight loss 哪儿来啊?</p><p>烦请各位大虾解答一下.谢了</p>
