Consumption Technology and the Intrafamily Distribution of Resources: Adult Equivalence Scales Reexamined
论证成人等价尺度的定义和测量取决于所采用的福利概念，并指出仅凭消费数据无法区分家庭技术因素（需求）与家庭内分配规则因素（意愿）。
This paper shows that the definition and the measurement of adult equivalence scales depend crucially on the concept of welfare used. When welfare is the utility parents derive from their own consumption , one has to assume separability of parents' and children's consumption. This assumption implies that the only way of imputing the intrafamily allocation of resources is by observing the consumption patterns of adult goods. Regardless of the definition used, one cannot separate the factors reflecting home technology (i.e., "needs") from those determining the intrafamily distribution rule (i.e., "wants") out of consumption data.
