Aggregate Consumer Behavior and Household Equivalence Scales
利用美国总体时间序列和个体截面数据，通过计量模型估计了按家庭规模、户主年龄、地区、种族和城乡划分的家庭等价量表，并给出了能源、食品等五类商品的特定等价量表。
Abstract This article presents estimates of household equivalence scales, broken down by demographic characteristics, of U.S. households. Separate estimates are given by family size, age of head, region, race, and urban versus rural residence. Commodity-specific scales are presented for five separate commodity groups—energy, food, consumer goods, capital services, and other services. The estimates are obtained from an econometric model of aggregate consumer behavior. The parameters of this model are estimated by combining aggregate time series and individual cross-section data.
