Parental time and children's obesity measures: a theoretical and empirical investigation
MetadataShow full item record
The increased prevalence of childhood obesity is a major concern for society. This study aims at exploring the influence of the parents (especially parental time allocation choices) on childrenÃ¢ÂÂs obesity-related health outcomes and examining the potential differences between the fathersÃ¢ÂÂ and the mothersÃ¢ÂÂ marginal effects. A household with two parents and one child is modeled. The household production theory and the collective household modeling structure are combined. The model treats the mother, the father and the child as three separate agents with individual preferences. The two parentsÃ¢ÂÂ interaction is modeled within the collective model framework by assuming that they will reach Pareto efficient resource allocation between them. In order to capture the dynamics between parents and the child, parents-child interaction is modeled in a two-stage Stackleberg game structure where the child is allowed to have certain decision choices of his/her own. This game structure allows us to explore the parental influence on the childÃ¢ÂÂs health outcomes while allowing the child to have influencing power in the household decision-making process. Based on this theoretical model, a general triangular system with one childÃ¢ÂÂs health production equation and five health inputs demand equations is derived and estimated. The empirical estimation is performed for three systems: pooled model, the younger children model (of age 9 to 11), and the older children model (of age 13 to 15). The empirical results show mother-related variables show more influence on the childÃ¢ÂÂs Body Mass Index (BMI) outcomes compared to father-related variables: mothersÃ¢ÂÂ BMI and mothersÃ¢ÂÂ work-to-home stress spillover are positively related to their childrenÃ¢ÂÂs BMI while mothersÃ¢ÂÂ time spent with their children is negatively related to their childrenÃ¢ÂÂs BMI. There exists a complementary relationship between mothersÃ¢ÂÂ income and fathersÃ¢ÂÂ food preparation time. In the older children model, mothersÃ¢ÂÂ own income increases tend to decrease their time spent with their children. The main contribution of this study is that it develops a general theoretical framework to capture the dynamics in parents-child interaction. Based on this theoretical model, empirical analysis and future work can be conducted in a theoretically consistent way.
