※ 引述《chris1 (小刀)》之銘言： : 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 以下用詞，很多和教科書上的不太一樣 (i) GDP = GVA (tax and subsidy is not mentioned) GVA = Σoutput - Σintermediate consumption = total output of coconut production and rental activities minus cost of fertilizers and rent = (75,000 + 30,000) - (15,000 + 30,000) = 60,000 Therefore, GDP = GVA = 60,000 (ii) GDP = Final consumption expenditure + GCF + net export = the total value of coconuts consumed (incl. export) plus changes in inventories minus import (GFCF is not mentioned) = 90,000 + (X-15,000) - 15,000 = 90,000 + (-15,000) - 15,000 (X = output of coconut production minus (total value of coconuts consumed minus value of coconuts sold in stock) = 75,000 - (90,000 - 15,000) = 0 ) = 60,000 消費的九萬，包括當年產出的，與之前的存貨 之前存貨的價值有多少，題目並沒有交待 我們只知道前一年存貨增加的價值為五千 題目先給定售出存貨的價值為一萬五，不管消費給多少，GDP 仍然是六萬 (a) 如果消費等於九萬，表示當年生產的椰子全部賣出， 即上述 X = 0，存貨變化為 -15,000 GDP = 90,000 + (-15,000) - 15,000 = 60,000 (b) 如果消費小於九萬，表示當年生產的椰子沒有賣完而成為存貨， 即上述 X > 0，存貨變化為 X-15,000，消費為 90,000-X， GDP = (90,000-X) + (X-15,000) - 15,000 = 60,000 (c) 如果消費大於九萬，表示當年生產的椰子不僅賣完， 商人還進口其他地方生產的椰子，即上述 X 屬於進口的項目， GDP = (90,000+X) + (-15,000) - (15,000+|X|) = 60,000 (iii) GDP = gross operating surplus and mixed income plus compensation of employees (tax and subsidy is not mentioned) = GVA - compensation of employees plus compensation of employees = GVA = 60,000 地主的租金收入為 30,000 商人與農夫的收入總和為毛利 = 銷售 - 銷貨成本(肥料 + 租金 - 存貨變化) = 90,000 - (15,000 + 30,000 - (-15,000)) = 30,000 --
