These outcomes are the experiment’s dependent variables.

这些结果是实验因变。

Our dependent variables are the volume of employment and the national income (or national dividend) measured in wage-units.

我们因变是就业和以工资单位（或红利）。

But you can also have variables that you believe are affected by changes in your independent variable; these are your dependent variables.

但是您也可以拥有您认为受自变变化影响变；这些是你因变。

So we have one independent variable – receiving the voucher or not – and a bunch of possible dependent variables, like earnings, education, and health outcomes.

所以我们有一个自变——是否到代金券——以及一堆可能因变，比如、教育和健康结果。

To begin with, it may be useful to make clear which elements in the economic system we usually take as given, which are the independent variables of our system and which are the dependent variables.

首先，弄清楚我们通常认为经济系统中哪些要素是给定，哪些是我们系统自变，哪些是因变可能是有用。
