Valuing a reduction in the risk and severity of asthma
A large scale multi-country stated preference approach
Asthma is a non-communicable and non-curable lung disease that is associated with
an array of environmental contaminants and chemicals. Many of these hazards are subject
to regulation, or may be considered for regulation, in order to reduce exposures and
prevent human health risks. However, the available information on willingness-to-pay
(WTP) to avoid asthma or reduce its severity is scarce, incomplete and does not provide
estimates compatible with welfare economic theory that can be used in cost-benefit
analysis.
This paper is part of the series of large scale willingness to pay (WTP) studies resulting
from the Surveys to elicit Willingness to pay to Avoid Chemicals related negative
Health Effects (SWACHE) project that intends to improve the basis for doing cost-benefit
analyses of chemicals management options and environmental policies in general. The
present paper offers values suitable for use in cost-benefit analyses of the WTP for
reduced severity of asthma attacks in adults and children and in reduced probability
of getting asthma for these two population groups, all in the context of reducing
chemical exposures, and covering populations in seven OECD countries: Canada, Czech
Republic, France, Poland, Sweden, the United Kingdom and the United States. The context
for such WTP elicitations was a set of household products that contain fewer hazardous
chemicals than what is currently available in supermarkets but are more expensive.
