其次，我们可以使用等价尺度来比较不同人口特征的家庭之间的福利水平。理想的家庭津贴、收入维持方案、所得税等的标准水平，然而，与需求分析相比，福利分析需要更多的信息来估计等价尺度。Pollak和Wales（1979）认为，福利比较所需的等价尺度与需求分析中出现的等价尺度在逻辑上是不同的，它们区分了无条件等价尺度和条件等价尺度。在福利分析中，父母的效用应该从商品数量和子女数量两个方面来界定。子女的数量是一个决定变量，而不是一个外生变量。观察到的两个和三个孩子家庭消费模式的差异甚至不能揭示他们认为第三个孩子是福还是祸。因此，我们需要更多的信息比包含在家庭消费数据，以估计福利比较的等效尺度。如果孩子是父母的福气，等值尺度显示了收入维持计划的上限。
Secondly, we can compare the welfare level between households of different demographic characteristics using equivalence scales. The standard level for desired family allowance, income maintenance programs, income taxes, etc., can be measured More information is, however, required to estimate equivalence scales for welfare analysis than for demand analysis. Pollak and Wales (1979) suggest that the equivalence scales required for welfare comparisons are logically distinct from those which arise in demand analysis, and they distinguish between unconditional equivalence scales and conditional equivalence scales. The utility of parents should be defined on both commodity quantities and the number of children in the welfare analysis. The number of children is a decision variable rather than an exogenous variable. Observed differences in consumption patterns of two-and three-child households do not even reveal whether they regard a third child as a blessing or a curse. We therefore need more information than contained in household consumption data to estimate equivalence scales for welfare comparison. If children are a blessing for the parents, equivalence scales show the upper limit for income maintenance programs.
