下图反映的是在一定时期内M商品的供求量(Q轴)随价格(P轴)变化的情况。曲线D为需求曲线,S为供给曲线,E为M商品的均衡价格。假定其他条件不变,下列关于均衡价格E变动的描述正确的是

①当居民当前可支配收入增加时,会导致均衡价格E→E

②当居民预期未来收入不确定时,会导致均衡价格E→E1

③当M商品预期未来价格上涨时,会导致均衡价格E→E2

④当M商品互补商品价格上涨时,会导致均衡价格E→E2

A.①②

B.②③

C.③④

D.①④

答案

答案:D

题目分析:当居民当前可支配收入增加时,需求曲线会向右移动,均衡价格提高,会导致均衡价格E→E1,①入选;当居民预期未来收入不确定时,会导致均衡价格E→E2,故②错误;当M商品预期未来价格上涨时,人们会抢购,故会导致均衡价格E→E1,故③错误;当M商品互补商品价格上涨时,人们会减少对M商品的需求,故需求曲线向左移动,④入选,本题正确答案为D。
