The tension between economic development and ecological protection has become more intense in the United States in the past few decades as population is rapidly spreading into areas with high natural amenities, most notably the mountainous rural regions of the "New West" and exurban counties with abundant open space amenities. This dissertation addresses three different aspects related to the interactions between regional economic development and natural amenities. The first essay focuses on the question of how regional economic growth interacts with ecological processes and specifically, how the rate of economic growth relative to the rate of ecological change matters in terms the sustainability of the joint ecological-economic system. Within the theoretical framework of a coupled nonlinear ecological-economic system characterized by slow-varying migration and fast-varying ecological change, I find that fast regional economic growth can render the system more vulnerable to exogenous shocks that cause the system to collapse; however, faster economic growth can also increase the speed with which the system returns to a sustainable economic equilibrium whenever it survives a shock. We also find that economic and ecological interventions can enhance both social welfare and system resiliency, but to degrees that depend on the underlying rate of regional economic growth. The common simplifying assumptions regarding the relative speeds of economic and ecological adjustment are assessed and the conditions under with such simplifying assumption can be applied are identified.

520 $a The tension between economic development and ecological protection has become more intense in the United States in the past few decades as population is rapidly spreading into areas with high natural amenities, most notably the mountainous rural regions of the "New West" and exurban counties with abundant open space amenities. This dissertation addresses three different aspects related to the interactions between regional economic development and natural amenities. The first essay focuses on the question of how regional economic growth interacts with ecological processes and specifically, how the rate of economic growth relative to the rate of ecological change matters in terms the sustainability of the joint ecological-economic system. Within the theoretical framework of a coupled nonlinear ecological-economic system characterized by slow-varying migration and fast-varying ecological change, I find that fast regional economic growth can render the system more vulnerable to exogenous shocks that cause the system to collapse; however, faster economic growth can also increase the speed with which the system returns to a sustainable economic equilibrium whenever it survives a shock. We also find that economic and ecological interventions can enhance both social welfare and system resiliency, but to degrees that depend on the underlying rate of regional economic growth. The common simplifying assumptions regarding the relative speeds of economic and ecological adjustment are assessed and the conditions under with such simplifying assumption can be applied are identified.
520 $a The second essay focuses on the optimal management of ecological thresholds when impacts from human activities not only trigger an ecological threshold effect, but also respond to subsequent ecological changes. Such two-way interactions are typical of many ecological-economic interactions. As an example, we study the management of a eutrophication threshold of a lake ecosystem when the run-off from developed land is affecting and at the same time responding to the lake water quality. I show that a naive policy that seeks to reduce run-off and improve lake water quality only by regulating the polluting source may not work due to the two-way interactions. In fact, such a policy can actually lead to more serious pollution in the long run and destabilize the ecological system. I also show that the effectiveness of a safe minimum standard hinges on two-way interactions as well. To manage a dynamically interacting ecological-economic system, it is necessary to adopt an integrated modeling approach that accounts for both human impacts on the ecology and ecological impacts on human behavior. Technically, through numerical simulation, I have solved a dynamic optimization problem with multiple equilibria and identified the coexistence of multiple solutions due to the non-convexity of the problem.
520 $a The third essay explores the mechanism underlying the pattern formation of exurban land uses given assumptions about household preferences for natural amenities and land heterogeneity in both the agricultural productivity and conversion costs. In particular, I contribute to the literature on land development by the provision of a micro-foundation for the capitalization process of non-marketable amenities. With the assistance of geographical information system, I am able to simulate my theoretical spatial economic model using actual data on land heterogeneity and the location of urban and natural amenities. The simulation result is then used to assess the theoretical predictions of the model in terms of the evolution of exurban land development patterns over a thirty year period. The model is unable to reproduce the observed land use pattern. This suggests that the spatial heterogeneity in agricultural productivity, conversion cost and natural amenities, open space amenities in particular, are insufficient to fully capture the complex spatial pattern of land development. Further research is needed to elaborate both the theoretical foundation for spatial land conversion decisions and to incorporate the impact of regulating policies on development and the provision of local public services such as sewer and water and educational services.
