This research extends prior work on formation of risk beliefs and willingness to pay to avoid skin cancer by analyzing decisions parents make concerning their own health, the health of their children, and the health of others outside their immediate family. The research will address five questions: (1) What determines parents' (ex ante) subjective beliefs about their own and their children's risk of contracting skin cancer?; (2) What protective actions do adults take to reduce risks of skin cancer to themselves and to their children?; (3) How much are parents willing to pay (ex ante) to reduce their own and their children's risk of contracting skin cancer?; (4) Are parents willing to pay an additional sum to protect the world's population from skin cancer?; and (5) How do income, family structure and composition, parental education, and other characteristics affect willingness to pay, risk beliefs, and risk-related behaviors?


Survey data would be collected according to a unified theoretical framework on perceived risks, protective action, valuation, and altruism. Surveys would be administered by computer to samples drawn from the Hattiesburg, Mississippi Metropolitan Statistical Area, and the Laramie, Wyoming area. The two surveys would be conducted in different years so that any new research questions arising from analysis of the first sample could be investigated in the second. Equations would be econometrically estimated showing determinants of risk-related behaviors (e.g., use of sunscreen and time spent outdoors), risk beliefs, and preferences for risk reduction. The equations would identify differences in how parents view risk to themselves versus risks to children and would be used to develop an indifference map that shows how parents trade off their health against that of their children.

Expected Results:

The proposed research will provide direct evidence on both the absolute and relative valuation of child and adult health, on the formation of parental beliefs about risks to their own and their children's health, and on the determinants of risk-related behavior. The current lack of evidence on these issues impedes evaluation and assessment of environmental policies affecting adults and children. By improving understanding of health risk and valuation, the project will promote more cost-effective allocation of federal and state environmental protection resources.
