我的文章主要不是讲如何分家的，而是讲不管是利他主义的还是利己主义，都不会
影响一个社会对既有产品的估价。但对利他主义的理解，我和两位教授都不同。利

关于效用的计量则稍嫌复杂，我又正忙得脚跟朝前，恐怕一时半会儿的不能给出明
确答案，此处抄几句书，先抵挡一下：)
Cardinal Utility
There are some theories that attach significance to the magnitude of utility. There are known as cardinal utility theories. In a theory of cardinal utility, the size of the utility difference between two bundles of goods is supposed to have some sort of significance.
One could propose various definitions for this kind of assginment: I like one bundle twice as much as another if I am willing to pay twice as much for it. .... There is nothing wrong with any of these definitions; each one would give rise to a way of assigning utility levels in which the magnitude of the numbers assigned had some operational significance. But there is not much right about them either. Although each of them is a possible interpretation of what it means to want on thing twice as much as another, none of them appears to be an especially compelling interpretation of that statement....Knowing how much larger does not add anything to our description of choice.
(Hal R. Varian Intermediate Microeconomic, 1999:57-8.)
