Childhood Obesity Risk and the Role of Primary Caregivers: A Triangular Semi-parametric Simultaneous Equations Approach AgEcon
Xue, Hong; You, Wen; Nayga, Rodolfo M., Jr..
This essay investigates the impacts of primary care giver’s (PCG) time allocation and food expenditure choices on childhood obesity using national panel study of income dynamic (PSID) data. A triangular system of equations is derived and estimated under parametric and semi-parametric model settings. The performances of the two modeling strategies are compared using predictive ability measures with the aid of bootstrap method. Test results suggest relatively better performance of the semi-parametric model than parametric model. Nevertheless, the comparison of the estimates from both parametric and semi-parametric estimation indicates no dramatic changes in our findings. Our results do not suggest significant impacts of PCG’s labor force participation...

HIV/AIDS and Adolescent's School-Work Choices in Malawi AgEcon
Nankhuni, Flora J..
Malawi is facing a severe HIV/AIDS Pandemic. With an estimated prevalence rate of 14.2%, it ranks eight in the world. About 900,000 Malawians were infected by 2003 and there were110,000 new infections and 87,000 deaths due to HIV/AIDS in 2003. The disease has poten tially devastating impacts. For example, 'taking children out of school' is mentioned as one of the coping mechanisms (Garbus 2003) but evidence is mixed. Doctor (2004) found no statistically significant difference between enrollment of orphans and non-orphans and mentioned an effective extended family structure as explanation. However, HIV/AIDS, poverty, macroeconomic policies, and food shortages are reported to render informal safety networks of the extended family systems irrelevant (Garbus...
