你现在承认月饼土了。请复习我前面说的:
你绝对是个小农,举出的例子也是小农,还花这么多时间来编故 ...
哈哈哈,曼昆讲解GDP的统计,他举的例子你欣赏一下,经济体一共就生产了4个苹果三个橘子,哈哈哈
这是小农还是大农?是社会化大生产?
Suppose, for example, that the economy produces four apples and three oranges. How do we compute GDP? We could simply add apples and oranges and conclude that GDP equals seven pieces of fruit. But this makes sense only if we think apples and oranges have equal value, which is generally not true.
(This would be even clearer if the economy produces four watermelons and three grapes.)
To compute the total value of different goods and services, the national income accounts use market prices because these prices reflect how much people are willing to pay for a good or service. Thus, if apples cost $0.50 each and oranges cost $1.00 each, GDP would be
GDP = (Price of Apples * Quantity of Apples)+ (Price of Oranges *Quantity of Oranges)
=($0.50 * 4) + ($1.00 *3)= $5.00.
GDP equals $5.00—the value of all the apples, $2.00, plus the value of all the oranges, $3.00.
