This study uses optimal control theory to examine the dynamic features of agricultural landscapes characterized by spatial externalites. A stylized system of agricultural production and groundwater flow is used to illustrate how spatial externalities affect land use decisions over time. Policy...

In this paper, we use a simple urban economic model to study how choosing park locations within a city might contribute towards urban planning goals. For multiple possible park placements, we solve for the associated equilibrium urban structure, including the equilibrium rent gradient, city...

This paper analyzes the effects of providing environmental amenities associated with open space in a discrete space urban model. The discrete space model assumes distinct neighborhoods in which developable land is homogeneous within a neighborhood but heterogeneous across neighborhoods. We solve...

A mail survey was conducted in Minnesota in 1997 to estimate the value of reducing phosphorus levels in the Minnesota River by 40%. The general population survey of river basin residents was designed to gather information about respondents' use of the Minnesota River in addition to their...

This study compares subsurface drip irrigation and sprinkler irrigation with respect to expected returns, aquifer life, nutrient utilization and accumulation in the production of irrigated corn using swine effluent and fresh groundwater from a depleting aquifer in the Oklahoma Panhandle. Most of...

Recent studies have suggested that green technologies may be a cost effective way to manage urban runoff. Literature has also suggests that there needs to be a greater empirical basis to estimate the benefits associated with social values associated with urban trees; we therefore estimate...

We explore the efficiency of allowing participants in transferable-rights programs to sell credits in multiple markets, i.e., to double dip. In a first-best economy double-dipping is efficient, but if the cap is set suboptimally, then the answer depends on the relative slopes of the marginal...

The study explores the implications of climate change for the economic costs of ecological conservation and restoration of submerged aquatic vegetation. It develops a methodological framework that addresses the key issues of uncertainty, irreversibility and space in climate change and...

This paper uses a two-good specific factors model to derive a relationship between international trade, land degradation, and welfare. Because developing countries enjoy comparative advantage in agriculture, they will export agricultural goods. We found that trade could lower steady state land...
