Evidence on substitutability of adult and child labour
利用埃及经济数据拟合生产函数，计算希克斯互补弹性及价格弹性，模拟国际终止童工呼吁对成人就业的影响，发现成年男性与童工互补、成年女性与童工替代，但禁止童工的就业效应不确定。
Whether child labour displaces adult labour, giving rise to unemployment, is a matter of their substitutability in production. Using a flexible form production function fitted to data on Egypt's economy, we generate Hicks elasticities of complementarity, own and cross‐price elasticities, as well as simulate employment effects on adult labour as a result of changing the fixed quantity of labour in compliance with the international call to end child labour. Adult males appear to be complementary with, and adult females substitutes for child labour, although the employment effects of banning child labour are inconclusive.
