Intrahousehold resource allocation in rural Pakistan: a semiparametric analysis
利用大型家庭调查数据，通过半参数恩格尔曲线估计家庭规模和构成对消费模式的影响，发现成年男性消费高于女性，儿童无性别差异，且食物消费存在规模经济。
We estimate semiparametric Engel curves for rural Pakistan using a large household survey. This allows us to obtain consistent estimates of the effects of household size and composition on consumption patterns even when these demographic variables are correlated with an unknown function of income. The coefficients on the household composition variables are used to infer patterns of intrahousehold allocation. While there is little evidence of gender differences among children, adult males appear to consume more than adult females. Amongst males, workers consume more than dependents. There is no evidence of differential treatment of the elderly or of higher birth-order children. We identify substantial economies of size in food consumption. We also find that Engel curves for food, adult goods and child goods are quadratic logarithmic, which implies that some commonly used demand models are inappropriate. © 1998 John Wiley & Sons, Ltd.
