GDP三種算法 - 經濟

on an island in the indian ocean, people grow coconuts, and

import fertilizers. A merchant manages all the farms. This year, they

used $15,000 fertilizers(imported that year) and grew $75,000 coconuts.

The merchant pays $30,000 to the landlord. Since last year was a year of

good harvest, the merchant of the village kept $5,000 coconuts as inventory.

This year, the merchant ends up selling the coconuts in stock for $15,000.

Therefore, the total value of coconuts consumed is $90,000 this year. What

was the island's GDP for this year? Please come up with the result by

(i) the product approach

(ii) the expenditure approach

(iii) income approach


搞不懂的點是，到底是不是消費了90000呢? 但今年明明只收成了75000不是嗎...

題目的意思是還有加去年的5000嗎? 但加起來也才80000而已...搞不懂怎麼來的

九萬，而且，那個15000，是賣剩下來，當今年的存貨嗎？


我的想法是，假如九萬是錯的，那

(i) 75000，因今年度就只生產出這75000的coconuts，要再扣進口15000嗎?

(ii) C=75000+5000-15000=65000 I=15000-5000=10000 M=15000

GDP=65000+10000-15000=60000

(iii) 30000(farmers)+30000(landlord)=60000


不知道這樣對不對呢？請幫幫忙，感恩
