"This study had two main goals. The first was to test the hypothesis that women who work in the informal sector of the labor force have better-nourished children, ceteris paribus, than women who work in the formal sector. A simple home production model for child nutrition incorporating this hypothesis was specified and the behavior of a utility-maximizing household investigated. The empirical estimates of the nutritional status production function provided no convincing support for the hypothesis." The second goal was "to investigate the joint determinants of child nutrition and of women's fertility and work choices....[It is suggested] that increases in women's education and formal sector wages will induce declines in fertility and improvements in child nutrition. Increases in informal sector wages will improve nutrition but have little impact on fertility, and income effects are minimal on all three variables." Data are from a household survey conducted in Nicaragua in 1977 and 1978.
本研究有两个主要目标。第一个目标是检验这样一个假设：在其他条件相同的情况下，在劳动力非正规部门工作的女性所养育的孩子营养状况更好，优于在正规部门工作的女性。构建了一个纳入该假设的儿童营养简单家庭生产模型，并对效用最大化家庭的行为进行了研究。营养状况生产函数的实证估计结果并未为该假设提供令人信服的支持。第二个目标是“研究儿童营养、女性生育及工作选择的共同决定因素……[研究表明]女性教育水平和正规部门工资的提高将导致生育率下降和儿童营养状况改善。非正规部门工资的提高将改善营养状况，但对生育率影响不大，且收入效应在这三个变量上均微乎其微。”数据来自1977年和1978年在尼加拉瓜进行的一项家庭调查。
