The Welfare Effects of Toxic Contamination in Freshwater Fish
通过连接EPA调查与水质数据，使用重复离散选择模型估算消除纽约州淡水鱼有毒污染的人均年福利收益约为63美元。
Very little study has been made of the welfare cost of toxic contamination in freshwater fish, primarily because appropriate data sets have not been available. This paper estimates the benefits of removing toxic contamination from New York State water bodies by linking the Environmental Protection Agency's Aquatic Based Recreation Survey with water-quality data from the New York Department of Environmental Conservation. Using a repeated discrete choice model of fishing behavior, we find that the elimination of toxic contamination from New York lakes and ponds would generate an annual benefit of about $63 per capita, per season.
