Children as consumers: investigating child diary expenditure data
利用英国家庭支出调查中的儿童日记数据，研究学龄儿童的支出行为，发现饮料、糖果、书籍和玩具是正常品，而衣物、旅行、休闲和不良品是奢侈品，且单亲家庭和母亲工作显著影响儿童支出。
Abstract. We investigate expenditure behaviour of school‐aged children using child diary information contained in the British Family Expenditure Survey. The estimates from an Almost Ideal Demand System (AIDS) for child expenditure suggest that drinks, sweets, books, and toys are ‘normal’ goods for children, but clothes, travel, leisure and vice products are ‘luxury’ items with income elasticities greater than one. Being a lone‐parent child and having a working mother are important factors in determining child expenditure decisions. Importantly, a higher parental budget share on any given commodity is typically associated with an increased child budget share on the same commodity.
