THE DYNAMICS OF INCOME‐RELATED HEALTH INEQUALITY AMONG AMERICAN CHILDREN
利用美国面板数据，研究儿童成长过程中收入相关健康不平等的稳定性，发现收入本身是主要因素，但健康变化更有利于初始收入低的儿童，而收入排名变化则与后续健康正相关。
We estimate and decompose income-related inequality in child health in the USA and analyze its dynamics using the recently introduced health mobility index. Data come from the 1997, 2002, and 2007 waves of the Child Development Supplement of the Panel Study of Income Dynamics. The findings show that income-related child health inequality remains stable as children grow up and enter adolescence. The main factor underlying income-related child health inequality is income itself, although other factors, such as maternal education, also play a role. Decomposition of income-related health mobility indicates that health changes over time are more favorable to children with lower initial family incomes versus children with higher initial family incomes. However, offsetting this effect, our findings also suggest that changes in income ranking over time are positively related to children's subsequent health status.
