※ 引述《betray911015 (回头太难)》之铭言： : Use your understanding of the IS-LM-BP model to answer this question. : Assume at the initial equilibrium that output is above the target level : of output and that a private payment surplus exists. Given this : information, we know with certainty that which of the following policy : actions will simultaneously achieve both internal and external balance? : a) increase in the nominal money supply : b) reduction in the nominal money supply : c) increase in government expenditures : d) reduction in government expenditures : e) more information is needed to answer this question : 题目说一开始的均衡产出在目标的水准之上，接下来的意思我就不懂了 : 题目是要问什麽?? 答案是 d) reduction in government expenditures 这题是说目前的产出超出自然水准 而原因是a private payment surplus exists 姑且不论是因为overinvetment or overconsumption所造成 这都表示是过度的民间支出推升了IS Y=G+(I+C)+Net EX 降低政府支出G即可拉回IS并恢复自然平衡 --
