问题
A variable whose value is determined by the model of which it is a part is termed______.
选项
A、constant
B、endogenous
C、exogenous
D、independent
答案
B
解析
答案为B项。endogenous variable“内生变量”。在计量经济模型中,指由模型本身加以说明的变量。它是模型方程式中的未知数,其数值可由方程式求解获得。exogenous variable “外生变量”。在计量经济模型中,指不能由模型本身加以说明的变量。它是方程式中的已知数,其数值不是由模型本身的方程式算得,而是由模型以外的因素产生。本题中的变量本身是由模型决定的,属于内生变量,故选B项。
