我有个问题，在这里提出，希望有识之士可以相助。在下不胜感激。
曼昆在第二章中，写GDP概念的时候，提到了一个很重要的注意方面：
The Treatment of Inventories
Imagine that a bakery hires workers to produce
more bread, pays their wages, and then fails to sell the additional bread. How
does this transaction affect GDP?
The answer depends on what happens to the unsold bread. Let’s first suppose
that the bread spoils. In this case, the firm has paid more in wages but has not received
any additional revenue, so the firm’s profit is reduced by the amount that
wages are increased.Total expenditure in the economy hasn’t changed because
no one buys the bread.Total income hasn’t changed either—although more is
distributed as wages and less as profit. Because the transaction affects neither expenditure
nor income, it does not alter GDP.
Now suppose, instead, that the bread is put into inventory to be sold later. In
this case, the transaction is treated differently. The owners of the firm are assumed
to have “purchased”the bread for the firm’s inventory, and the firm’s profit is notreduced by the additional wages it has paid. Because the higher wages raise total
income, and greater spending on inventory raises total expenditure, the economy’s
GDP rises.
厂家就相当于消费者的角色，是支出，而劳动者是收入方。这好像和我们平时的理解不一样，以为工人是消费者，厂家是收入方。总结出一点就是，有一笔收入，有与之对应的一笔支出的部分才能被算入GDP或者GNP,我这种理解，大家怎么看？
