我们在本竟提到了一国的外国将资产的盈亏不计入经常账户项下的泪民收入中。如果经济学家们希望

外国净资产的盈亏计入经常账户中，他们应如何重新修订经常账户的构成呢？在你看来，这样做有意义吗？你认为在实践中为什么没有这样做呢？

We mentioned in the chapter that capital gains and losses on a country's net foreign assets are not included in the national income measure of the current account. How would economic statisticians have to modify the national income identity (12-1) if they did wish to include such gains and losses as part of the definition of the current account？ In your opinion， would this make sense？ Why do you think this is not done in practice？
