02.单选题 已收藏 标记 纠错 Equality between aggregate expenditure and aggregate output implies that the government‘s fiscal deficit must equal: A Private saving - Investment - Net exports. B Private saving - Investment + Net exports. C Investment - Private saving + Net exports. 查看解析 上一题 下一题 正确答案A 您的答案A本题平均正确率：51% GDP calculation难度：一般 推荐：      答案解析 The fundamental relationship among saving, investment, the fiscal balance, and the trade balance is S = I (G - T) (X - M). This form of the relationship shows that private saving must fund investment expenditures, the government fiscal balance, and net exports (= net capital outflows). Rearranging gives G - T = (S -I) - (X - M). The government's fiscal deficit (G - I) must be equal to the private sector's saving/investment balance (S -I) minus net exports. 问：如图，紫色箭头标明的 1.aggregate output就是总收入 output为啥对应income？2.fiscal deficit是 G-T,G-T应该是盈余或者赤子吧，感觉表达的也不严谨？
