【多选题】以下关于乘数的说法正确的是( )。
A.
乘数是指某一经济量与由它引起的其他经济量变化的最终量之间的比率关系
B.
乘数等于边际储蓄倾向的倒数
C.
国民收入增加量的形成,初始动因是自发投资的增量,而中间的传导机制是消费的无限次循环,因此乘数模型又可称为消费无限次循环模型
D.
乘数与边际消费倾向呈正向变化的关系,与居民的边际储蓄倾向呈反向变化的关系
【简答题】特种铸造是除_________ 以外的其他铸造方法的统称, 如 __金属型铸造_____,__压力铸造___,___熔模铸造____,____离心铸造____及连续铸造等。
【判断题】外贸乘数理论认为,出口具有与国内投资同样的增加国民收入总量的效应,并在边际储蓄倾向、边际进口倾向的影响下,经过国民经济各环节的传导,致使由此而产生的国民收入变动金额数倍于出口的初始变动额。这个倍数就称为外贸乘数,数量上大体等于边际储蓄倾向与边际出口倾向之和的倒数。
A.
正确
B.
错误
