This dissertation consists of two research projects in the area of Environmental Economics: water-recycling technology adoption and its cost-effectiveness in the U.S. horticulture industry (in Chapter 2), and urban tree cover's impact on residential location decision making in Milwaukee, WI (in Chapter 3).
Chapter 2 evaluates the economic effects of labeling plants grown with water-recycling technology (WRT) practices in selected nursery operations in the Mid-Atlantic region of Virginia, Maryland and Pennsylvania. Partial budgeting, whole enterprise-level budgeting, sensitivity and break-even analyses are conducted to determine whether consumer premiums for plants grown with recycled water are sufficient to make WRT economically feasible combined with plant eco-labeling, and how such a labeling program would affect greenhouse/nursery production costs, gross revenues and net revenues. It is concluded that consumer premiums for plants grown with recycled water could offer nursery growers a method to improve their net returns while reducing pollution runoff and improving irrigation water usage efficiency.
Chapter 3 focuses on non-market valuation of environmental (dis)amenities. Specifically, this chapter investigates the impact of urban tree cover on residential property location decision in the housing market of Milwaukee, WI. Residential sorting model embedded with "horizontal preference structure" is established to estimate the heterogeneous preferences for tree cover and other land cover attributes that vary by household socio-economic characteristics and then to identify the housing property owners' demand for these land cover attributes. The first part of this chapter mainly recovers the demand for "community trees" at the census block group level combined with 10 years property transaction data and neighborhood characteristics where the median income is aggregated to represent the household annual income. It is found that "community trees" are positively valued by the housing property owners and have a positive impact on housing price due to its positive externalities. Furthermore, income is found to be a strong exogenous demand shifter, leading to heterogeneous preference for the tree cover.
The second part of Chapter 3 further investigates the impacts of both nearby trees and distant trees on residential property location decision using different spatial scales of land covers measurements. Instead of aggregating block group level median income, this study matches and merges disaggregated individual household annual incomes from the Home Mortgage Disclosure Act (HMDA) dataset to mitigate the potential aggregation bias. It is found that different spatial scales of land cover measurement result in varying willingness to pay estimates, implying that housing property owners have heterogeneous demands for nearby trees and distant trees. In other words, preferences for urban tree cover not only vary by household annual income, but also differ across spatial scales of the tree cover measurement. / Doctor of Philosophy / This dissertation contains two research projects related to researches on environmental economics. Chapter 2 talks about how adoption of water-recycling technology affects nursery growers’ finance (i.e., production cost, gross revenue, profit) and operation management in Mid-Atlantic region of Virginia, Maryland and Pennsylvania. It is found that consumers are willing to pay more money for horticultural plants produced with recycled water and these additional moneys would be sufficient for the growers to compensate the extra costs after adopting the water-recycling technology in the production. This study helps nursery growers and policy makers assess WRT adoption to improve crop water productivity and to reduce pollution of off-site surface waters. Chapter 3 discusses the impact of urban tree cover on housing price in the area of Milwaukee, WI. It is assumed that households with different socio-economic characteristics (e.g., household annual income) would have varying preferences for tree cover and other key characteristics when they make decisions on choosing their residential property locations. The first part of this chapter mainly focuses on “community trees”, namely the trees and forest within given census block groups. The second part of this chapter further takes nearby trees into consideration besides the distant trees so as to determine how trees on/near the residential properties affect the housing prices and whether the housing property owners prefer more trees on/near their properties. It is found that urban tree cover is valued by housing property owners and households with different income levels have diverse preferences for both nearby and distant trees. The research presented in this chapter not only makes academic contributions to the literatures of residential sorting model related to landscape (dis)amenities, but also facilitates the policy making of local governments and practitioners when it comes to urban and community trees and forestry programs.
