Nutritional efficiency wage of child labour: theory and policy implication

本研究提出了一个童工营养效率工资的理论模型，即童工的生产率取决于儿童时期的消费水平，雇用童工的企业根据儿童的营养水平决定营养效率工资。在这一模式中，依赖于成人人力资本的家庭收入是一个关键组成部分，因为家庭收入影响到童工的生产力，而不是消费分配。这意味着当家庭收入水平较低时，童工的营养效率工资较低。此外，本文还对人力资本进行了动态分析。低收入家庭的儿童教育对人力资本的贡献水平较低，这是因为童工的营养效率工资较低，而童工的劳动力需求较高。因此，儿童的人力资本是低水平的。因此，我们表明，贫困陷阱与低人力资本水平的可能性。

This research presents a theoretical model of nutritional efficiency wage of child labour that the productivity of child labour is determined by the level of consumption in childhood and firms employing the child labour decide the nutritional efficiency wage depending on the nutritional level of children. In this model, the family income depending on the adult human capital is a key component because the family income affects the productivity of child labour over the allocation for the consumption. It implies that the nutritional efficiency wage of child labour is low when the family income is low level. In addition, we present the dynamic analysis of the human capital. Child education for human capital is low level at the low family income because the nutritional efficiency wage of child labour is low and labour demand of child labour is high. As a result, the human capital of children is low level. Thus, we show that the possibility of a poverty trap with a low human capital level.
