关于economics的求government expenditure investment is 400,saving is 400.tax revenues are 500.exports are 300,imports are 200.求government expenditure.请写上公式
开放经济的国民收入,是本国和外国花费在本国生产要素生产的商品和服务的总和:
Y = C + I + G + EX – IM
? Y 代表GNP
? C 代表消费
? I 代表投资
? G 代表政府购买(government expenditure)
? EX 代表出口价值
? IM 代表进口价值
经常项目等于国民收入与国内居民花费的差额:
Y – (C+ I + G) = CA = EX – IM
其中,又可知道
Sp + Sg = S= I + CA
Sp = I + CA - Sg = I + CA + (G – T) (12-2)
– T 代表政府“收入” (净税收)
– Sg 政府储蓄= T- G
– 私人储蓄=Sp
– 开放经济中,储蓄既可用于积累资本存量,也可用于获取外国财
富S = Y-C-G= I + CA
– 所以 Sp = I + CA - Sg = I + CA + (G – T)
如果你这里的saving是指私人储蓄Sp,代入上面这公式即可
400=400+(300-200)+(G-500)
可得G=400
