解释:利率前面为什么加个real,如果是名义利率在I/S当中哪里会出现问题
NO.PZ2016010801000054 记得图像是向上倾斜
NO.PZ2016010801000054 reinterest rates anrespenng amount, anis negatively slope reinterest rates anreaggregate income, anis negatively slope C is correct. The IS curve illustrates the negative relationship between reinterest rates anreaggregate income. Investment (I) ansavings (S) are the primary variables thaust to maintain the balanbetween expenture anincome 考点IS 解析IS曲线说明了实际利率与实际总收入之间的负相关关系。投资(I)和储蓄(S)是调维持收支平衡的主要调整变量。所以只有C正确。题目里说saving跟IS有关,怎么体现呢?IS 和LM分别是什么单词缩写呢
老师,为什么B不对呀,总支出不是等于总收入吗?
IS曲线的reinterest rate 是无风险利率risk-free rate 减去 E(Inflation rate)吗?
