Coastal areas in the United States generate substantial benefits to society resulting from both economic activity and non-market ecosystem services. There is a marked tradeoff between these two productive service flows that is often confounded by the lack of market prices for the non-market goods. This dissertation is composed of three essays that use nonmarket valuation techniques to address the welfare implications of these tradeoffs in terms of adaptation to climate change and biodiversity loss in coastal environments.
