Estimation of Health Effects and Values for Air Quality Improvements: the Cases of Taiwan and Los Angeles
The goals of this proposal are to improve understanding of the epidemiological links between air pollution and acute health in the United States and Taiwan, to provide the first evidence using Contingent Valuation (CV) approach about willingness to pay for health improvements in a newly industrialized country (NIC), and to investigate problems in the transfer of epidemiological relationships between the United States and an NIC. To accomplish these goals, the researchers propose to use the survey results of three efforts: an epidemiological study for a panel of residents of the Los Angeles, area, the design and administration of an epidemiological survey following similar protocols in Taiwan, and the design and administration of a CV survey in Taiwan involving participants in the epidemiological survey. The researchers will use these results in the following ways: (1) to estimate a model for the willingness to pay to avoid episodes of illness, using the Taiwan CV data; (3) to estimate a model for the occurrence of symptoms and symptom combinations and multiday episodes, comparing the results to the Taiwan study and exploring model that pools the two data sets. The latter work would allow the researchers to apply the Los Angeles results to Taipei to gain insight into the prediction errors involved in transferring concentrations-response functions from U.S. cities to cities in other parts of the world.
