Simultaneous Determination of Home Work and Market Work of Women in Urban West Africa
使用联立Tobit模型，分析几内亚科纳克里女性在家庭劳动和市场劳动上的时间分配，发现教育年限非线性影响市场劳动供给，基础设施因素（如交通成本和电力）对时间分配有显著影响。
Little is known about how women in urban environments in developing countries allocate their time. A simultaneous tobit model of hours in market work and home work, incorporating jointness in decisions regarding time in these activities and allowing for non-participation in either activity, is estimated on a sample of women from Conakry, Guinea. The results indicate that years of formal schooling has non-linear effects on women's market labor supply, becoming positive only around completion of primary school. As in rural areas, infrastructural factors such as transportation costs and access to electricity have substantial impacts on female time in home and market activities.
