Sylvie Lambert et al., « Sons as widowhood insurance: Evidence from Senegal », HAL-SHS : économie et finance, ID : 10.1016/j.jdeveco.2016.01.004
Exploiting original data from a Senegalese household survey, we provide evidence that fertility choices are partly driven by women's needs for widowhood insurance. We use a duration model of birth intervals to show that women most at risk in case of widowhood intensify their fertility, shortening birth spacing, until they get a son. Insurance through sons might entail substantial health costs since short birth spacing raises maternal and infant mortality rates.
