C
已知乘数为6.25(The value of the multiplier for this economy is 6.25),由于乘数=1/(1-MPC)
故可求得MPC=0.84
从而根据收入变化,可知消费支出变化量为0.84*(230-200)=25.2
因此消费=145+25.2=170.2

1. y1 + y2 = 25
5 + 2*y1 = 40 + y2
解联立方程得
y1 = 20
y2 = 5
2. y = y1 + y2
MC = MC1 = MC2 = (MC1 + 2*MC2)/3 = [(5+2*y1) + 2*(40+y2)]/3
MC = 85/3 + 2*y/3

初级宏观经济题目
Artland can produce 600 hats or 300 bicycles whereas Rayland can produce 1200 hats or 300 bicycles
Q:
1)calculate the opportunity cost of a bicycle in Artland
2)if the 2 countries specialize and trade, which country will import bicycles? explain!
3)if the terms of trade are 5 hats for 1 bicycle, would trade be advantageous for each of the following? (1) Artland (2)Rayland
刚刚接触宏观经济,所以想请教一下答题思路是否正确
第一题:A 生产1 bicycle就可以生产2 hats,根据定义,所以the opportunity of a bicycle 就是舍弃掉的2 hats 对吗?
至于第二题,不是很能解释得清楚……是R吗?
第三题,我觉得是……不行,完全混乱了……

1、你的理解是正确的.
2、如果专业化,谁进口bicycles.因为生产bicycles的机会成本Artland(0.5)小于Rayland(0.25),所以Rayland将生产帽子,而Artland将生产bicycles.所以,Rayland进口bicycles.
3、如果帽子和自行车的贸易比例是5:1,谁拥有优势?Rayland.假如A生产100hats,或者自己50bicycles,或可以换得20bicycles.而R生产100hats,或者自己25bicycles,或可以换得20bicycles.
