为什么这道题不考虑 cost-push inflation?
NO.PZ2018062003000109 问题如下 If the energy priincreases sharply, in the long run the overall prilevel will: A.keep raising if the centrbank takes no steps. B.stunchangelong the money supply esn’t increase. C.keep raising until all prices have increasethe same proportion. B is correct.If the money supply is not expanthe centrbank, anthe aggregate mancurve esn’t change, wnwarpressure will brought to the input prilevel back. In the long run, the prilevel ten to stunchange考点AS曲线解析能源价格的攀升会造成总供给的衰退,总供给的衰退在长期会引起原材料价格的下降,从而使得总供给恢复到初始水平。这期间,如果该国央行不实施干预,那么总需求就不会发生改变。总供给和总需求在长期都未改变的结果就是物价水平保持不变。 请问题目解析的意思是短期和长期,央行不干预的情况下总需求曲线都不会发生改变吗?央行干预的话会两条曲线又会发生怎样的变化呢?

NO.PZ2018062003000109 题目问的不是总体价格水平吗?和总需求有什么关系呢
这道题事怎么看出对as曲线问题提问的呢?题目中只谈到能源看价格快速上涨问价格水平水平如何变化
