Objective:

This project is aimed at improving the valuation of environmental health risks. The broad goal of the work is to determine the feasibility of developing credible and accurate values of reducing morbidity risk that can be widely applied or transferred when estimating the benefits of environmental policies. More specifically, we propose to conduct a stated-preference survey to estimate the effects of several attributes (i.e., duration and severity of symptoms, the dimensions of health that are impaired, and whether the illness is identified by name) on willingness to pay (WTP) to reduce morbidity risk from environmental contaminants. We will compare WTP to reduce risks of illness to the respondent, a child, and another adult in the household.

Progress Summary:

We have developed the survey instrument, resolving issues related to the experimental design, risk attributes, measures of health status, and selection of a market-based scenario for reducing health risk. We have also subcontracted administration of the survey to Knowledge Networks, a qualified research firm with expertise in web-enabled surveys.

Future Activities:

The survey instrument will be finalized and delivered to Knowledge Networks for programming and testing. After testing is complete, we will field a small pretest, revise the survey if necessary, and field the main wave of the survey. We anticipate fielding the main wave of the survey this summer and analyzing the data this fall.
