Does parents’ valuation of children’s health mimic their valuation of own health?

A single latent variable model of health status and therapeutic health care utilization is estimated for parents and own children of 6,557 US households. The equation system that identifies latent health status simultaneously determines a number of indicators of general health, including presence of morbidity symptoms, mobility limitations, medication needs, and utilization of therapeutic health care services. The main goal of the paper was to obtain an unbiased estimate of parents’ marginal substitution rate between own and child health. Results indicate that parents’ valuation of their children’s health exceeds their valuation of own health by almost twofold on average.

Consumption Patterns of Chinese Children

In the ten-year period from 1990 to 1999, children's consumption has increased dramatically in proportion to family income. In 85% of urban families, children's average consumption is equal to one third or more of the family's income. Resources are being directed to children's food and dietary supplements, toys, travel, computers and other electronic equipment, and educational resources. Children perceive that they have a significant influence on the family's financial decision-making. Problems related to children's consumption include indulgence in unnecessary or harmful purchases, and conspicuous consumption that cannot be sustained by the family's income. While some child-focused spending is viewed as enriching development, other expenditures may harm the family's economic well-being and foster an overly materialistic outlook among children.
