Effects of household size and composition on consumption in rural households in Matabeleland South, Zimbabwe
基于1990/91年津巴布韦农村家庭调查数据，研究家庭构成变化对支出模式的影响，估算不同年龄段家庭成员（包括儿童）的消费成本，并发现产品组间存在显著差异，且这些效应在大家庭中较弱。
Abstract This study, using a survey of rural households in Zimbabwe in 1990/91, focuses on the effects of changing household composition on patterns of expenditure and provides estimates of the ‘cost of a child’ as well as of family members in other age groups. In addition to age differences in the size and direction of responses to changing family composition, the paper highlights significant differences across product groups. These effects are more muted in larger households.
