Financial incentives for sanitation take-up: A randomized control trial in rural Vietnam.

This study assesses the impact of financial incentives on hygienic latrine ownership by poor/near-poor households in Vietnam. Rural communes were randomly assigned to a control group and three treatment arm groups: (T1) a rebate for households that installed a hygienic latrine; (T2) a financial reward for commune governments if the proportion of hygienic latrines in their commune increased by 30 percentage points; (T3) both a household rebate and a commune reward. We find a strong and positive effect from the household rebate (treatment arms 1 and 3) but an insignificant effect from the commune reward (treatment arm 2) on household ownership of a septic tank latrine. Our analysis provides suggestive evidence that microcredit is a channel through which a rebate encourages the installation of septic tank latrines. We also find that treatment arm 3 increases people's knowledge regarding sanitation and the availability of water and soap for handwashing within households.

The Effect of Child Quantity and Education on Parents' Well-Being in Vietnam.

Background: Vietnam currently has a rapidly aging population, while formal social protection has only covered a small fraction of older people. Therefore, many older people with insufficient income or poor health must rely on their children's support. Method: This study uses the Vietnam National Aging Survey 2011 to determine whether the quality of children's education/employment and the number of children in a family impact older people's life satisfaction and health. Results: We find that the number of children has no effect on parents' life satisfaction but is adversely related to parents' health across a range of physical and mental health measures. In contrast, children's education has beneficial impacts on the well-being of elderly parents. Parents with better-educated children are more satisfied with their lives and report better health and fewer illness issues. Among other factors, income and wealth are strong and consistent predictors of older people's life satisfaction and self-perceived physical and mental health. Conclusion: To the best of our knowledge, this is the first study to explore the relationship between quantity and quality of children and the well-being of elderly parents. Our results show that the number of children has an adverse effect on older people's self-reported health and life satisfaction in Vietnam. Meanwhile, parental health and life satisfaction are significantly related to children's education. The findings of this study provide several practical implications. Most importantly, investment in education for children will have long-lasting impacts on the health and well-being of elderly adults. In addition, our paper indicates that the government program for reducing fertility has contributed to the longer-term health of people.

Children and female labor market outcomes in Vietnam.

This paper examines the effect of fertility on the participation of women in the labor market and other labor market outcomes in Vietnam, using Vietnam Labor Force Survey data. To address the endogeneity issue in fertility, we use an instrumental variable estimation method based on parental preference for the mixed-sex composition of the first two children. Our findings indicate that number of children has a negative impact on maternal participation in the labor market and on working hours but has no effect on earnings. We find that the effect on participation in the market is important for younger women aged 21-35 years but insignificant for older women aged 36-50 years. The older group responds by reducing their working hours rather than leaving the labor force. Our results support the position that the rise in female participation in the labor force in Vietnam can be partially attributed to the overall decline in fertility during the last three decades and helps validate the Vietnamese government's planning policy.
