Economic Analysis of the Potential Impact of Climate Change on Recreational Trout Fishing in the Southern Appalachians. Ph.D. Thesis, North Carolina State University, 137 pages. This study focuses on economic analysis of the potential impacts of climate change on recreational trout fishing in the Southern Appalachian Mountain area of North Carolina. Significant decreases in trout habitat and/or populations are expected in the study area if water temperature increases due to global warming. The main purpose of this study is to estimate the trout angler's welfare loss from the reductions of trout habitat and/or population in recreational trout fishing based on the climate change scenarios. Nested multinomial logit random utility models (RUMs) were used for the economic assessment and two nesting structures were examined -- the first with two decision levels and the second with three decision levels -- to describe an angler's choice behavior given a single occasion. The five scenarios used for estimating trout angler's welfare changes were 10, 20, 30, 40, and 50% reductions in both stream length and trout populations.
