最近也在学微观经济,也好晕。你把他们的图找出来对比下,还有边际成本marginal cost. 边际效益marginal benefit is the value of one more unit of good or service,value is the maximum price that a person is willing to pay. 就象网址里的例子,我们已经有好几个馒头了就不愿意再花高价买它了,馒头的价值也就小了。我们所拥有的数量Q越多,MB就会越小。MB=MC的时候,benefit是最大的,competitive market is efficient.边际效用marginal utility人们从消费某种商品或服务中得到的满足程度,每增加一个物品总效用的变化。随着物品数量Q不断增加,TU变大,MU越来越小。就是TU2-TU1=MU,增加一个量后用增加后的TU减去之前的TU.TU只会越来越大,而MU确不断减小了。让总效用最大有两个条件,1花光所有可用的钱,2MU1除以P1=MU2除以P2。MU1/P1>MU2/P2,就增加1物品的数量Q1去减小MU使他们平衡。有点象东西越多越不珍惜,这个东西给他的满足感也因为数量变多而减小了。价值勃论更说明了数量Q越多,TU越大,MU越小。MB强调的是benefit和数量quantity的关系。mu强调的是满足感和数量的关系。说的有点乱了,多看书,把图研究下就会好了。我这章考试死的很惨。还有价格变化了他们图形怎么变,收入变了图形怎么变。后面还有好几个边际**呢
