A new approach to the construction of family equivalence scales

The question of the money compensation which should be given to families of different sizes in order that they enjoy equal welfare levels is considered. By comparison of individual welfare functions, estimated for 3,000 individuals in the Netherlands, family welfare equivalence scales are derived. The obtained equivalence scale depends on family size and the ages of the family members. There are considerable ‘economies of scale’. The method employed may be used to derive money compensations for other situational differences. Evidence was found that people adapt their needs to situational changes. That effect was quantitatively assessed. Results are obtained and compared for various social subgroups.
