This study provides evidence on the principal determinants of pregnancy and abortion in India using a large country-wide district-level data set (DLHS 2007). The paper provides an economic framework for the analysis of pregnancy and abortion. The study distinguishes between induced and spontaneous abortion and compares the effects of their determinants. The results show that there are wide differences between induced and spontaneous abortions in terms of the sign and magnitude of the estimated effects of several of their determinants, most notably wealth, the woman's age and her desire for children. The study makes a methodological contribution by proposing a trivariate probit estimation framework that recognizes the joint dependence of pregnancy and induced and spontaneous abortion, and provides evidence in support of this joint dependence. The study reports an inverted U-shaped effect of a woman's age on her pregnancy and both forms of abortion. The turning point in each case is quite robust to the estimation framework. A significant effect of contextual variables, at the village level, constructed from the individual responses, on a woman's pregnancy is found. The effects are weaker in the case of induced abortion, and insignificant in the case of spontaneous abortion. The results are shown to be fairly robust. This paper extends the literature on the relation between son preference and fertility by examining the link between mother's son preference and desire for more children with abortion rates.
本研究利用一个覆盖全国范围的大型地区层面数据集(2007年全国家庭健康调查),提供了关于印度怀孕和堕胎主要决定因素的证据。本文为怀孕和堕胎分析提供了一个经济框架。该研究区分了人工流产和自然流产,并比较了它们各自决定因素的影响。结果表明,在几个决定因素的估计影响的符号和幅度方面,人工流产和自然流产存在很大差异,最显著的是财富、女性年龄以及她对孩子的渴望。该研究通过提出一个三变量概率单位估计框架做出了方法上的贡献,该框架认识到怀孕与人工流产和自然流产之间的联合依赖性,并提供了支持这种联合依赖性的证据。该研究报告了女性年龄对其怀孕以及两种流产形式呈倒U形影响。在每种情况下,转折点对估计框架都相当稳健。研究发现,根据个体回答构建的村庄层面的背景变量对女性怀孕有显著影响。在人工流产的情况下,这种影响较弱,在自然流产的情况下则不显著。结果显示相当稳健。本文通过研究母亲的儿子偏好与对更多孩子的渴望和堕胎率之间的联系,扩展了关于儿子偏好与生育关系的文献。
