經(jīng)濟(jì)學(xué)題目,有關(guān)消費(fèi)者剩余的,懂的進(jìn)!
英文原題：
1.Hiroo is willing to pay $10 for the first widget that he purchases each year,$9 for the second,$8for the third,and so on down to $1 for the tenth and nothing for the eleventh.The market price is $3 per widget.
a) How many widgets will he buy,and what will be his consumers' surplus?
b) The price of a widget rises to $5.How many widgets will he buy now,and how will his consumers' surplus change?
c) Can you state a generalization about the relationship between the consumers' surplus obtained and the price of a commodity?
自己翻譯成中文大致是這樣：
Hiroo愿意花10美元購買他每年的第一部件,第二年9美元,第三年8美元,以此類推,直到價格降到第十年的1美元,第十一年為0美元.市場價格為每件3美元.
A）他將購買多少個部件?他的消費(fèi)者剩余是什么?
B）若單個物品價格將漲到5美元,那么他將購買多少?他的消費(fèi)者剩余又會怎么變化?
C）簡述消費(fèi)者剩余和一種商品的價格之間的關(guān)系.
