Essays on environmental economics and resource management
| Title: | Essays on environmental economics and resource management |

| Description: | This dissertation includes 3 essays that study two important topics in environmental economics and resource management.The first essay considers the impacts of socioeconomic characteristics, Pfiesteria-related information and responders’ prior safety consideration on Pfiesteria concern, seafood risk perception and seafood consumption. We find that, besides the direct impacts, people with different socioeconomic background or with different prior safety considerations react differently to negative and positive risk information about seafood. The second essay assumes that, when people are asked to provide their responses in different scenarios, their multiple answers are impacted directly in sequence. This assumption is tested by applying the linear feedback count data model on a combined revealed and stated behavior data, which is from the same survey presented and used in the first essay. This paper is the first trial to capture the dynamics in the multiple answers when combined revealed and stated behavior data is used.The third essay examines the potential role of forest set-asides in global carbon sequestration policy. Set-asides potentially have the benefit of avoiding concerns about the permanence of forestry actions to sequester carbon by avoiding future carbon emissions, and they potentially provide large ancillary environmental benefits. They may also lead to large leakage if they are implemented inefficiently. This paper shows the potential scale of set-asides that would occur under three different types of crediting schemes for carbon inside and outside of forest set-asides. The results show that if set-asides are integrated optimally into a global forestry carbon sequestration program, about 300 million hectares of land would be set-aside, and up to 128 billion tons of carbon could be sequestered in global forests by 2105. If carbon credits are provided only on land where set-asides occur, 8-17% less carbon will be sequestered, depending on which lands are credited. Up to 3.2 billion hectares of land, however, would be entered into the set-aside forests. The total costs of the optimal sequestration program would be about $753 billion in present value terms over the century, while the total costs of engaging only in set-asides could be substantially more expensive, potentially twice as much. |
