Valuation of Reduction in Human Health Symptoms and Risks. Volume 3: Contingent Valuation Study of Light Symptoms and Angina

摘要

This is Volume 3 of a four volume report. The total project undertakes an assessment and reconciliation of attempts to value reductions in human health risks, and it develops new methods and estimates for these values. Volume 1 is the executive summmary. Volume 2 contains a comparative assessment of work on valuing health risks. Based on the assessment, a set of interim morbidity and mortality values applicable to effects of criteria air pollutants is developed. Volume 3 reports on a study developing and applying contingent valuation techniques to the types of light symptoms often attributed to air pollution. Volume 4 reports on the design of approaches for valuing serious or life threatening illnesses. Volume 3 reports on a contingent valuation study conducted as part of this project to estimate the benefits of light symptom reductions and angina relief. The approach is based on focus group experimentation followed by systematic household sampling.
