    Capitalized Costs of Habitat Conservation Easements (2014)
    Oxford University Press
    Details
    Publication Date: 2014-04-05
    Description: Perpetual conservation easements permanently remove the option to convert existing habitat to more intensive agricultural production. If existing habitat is at threat of conversion, removing the option to convert will reduce land values. In this article, we estimate the land value discount resulting from perpetual habitat conservation easements by using propensity score matching. We find that on the average eased parcel, land values fall by approximately $86 per acre for every acre of eased habitat. On average, our results suggest that landowners have been adequately compensated and conservation agencies have successfully secured habitat at risk of conversion.

    Crying Wolf? A Spatial Analysis of Wolf Location and Depredations on Calf Weight (2014)
    Oxford University Press
    Details
    Publication Date: 2014-04-05
    Description: Combining a novel panel dataset of 18 Montana ranches with spatial data on known wolf pack locations and satellite-generated climatological data from 1995-2010, we estimate the spatial impact of changing wolf pack locations and confirmed wolf depredations on the weight of beef calves. We find no evidence that wolf packs with home ranges that overlap ranches have any detrimental effects on calf weights. Other non-wolf factors, notably climate and individual ranch-specific husbandry practices, explained the majority of the variation in the weight of calves. However, ranches that experienced a confirmed cattle depredation by wolves had a negative and statistically significant impact of approximately 22 pounds on the average calf weight across their herd, possibly due to inefficient foraging behavior or stress to mother cows. For ranches experiencing confirmed depredation, the costs of these indirect weight losses are shown to potentially be greater than the costs of direct depredation losses that have, in the past, been the only form of compensation for ranchers who have suffered wolf depredations. These results demonstrate a potentially important and understudied aspect of economic conflict arising from the protection and funding of endangered species recovery programs.

    LUMINATE: linking agricultural land use, local water quality and Gulf of Mexico hypoxia (2014)
    Oxford University Press
    Details
    Publication Date: 2014-07-03
    Description: In this paper, we discuss the importance of developing integrated assessment models to support the design and implementation of policies to address water quality problems associated with agricultural pollution. We describe a new modelling system, LUMINATE, which links land use decisions made at the field scale in the Upper Mississippi, Ohio and Tennessee Basins through both environmental and hydrological components to downstream water quality effects and hypoxia in the Gulf of Mexico. This modelling system can be used to analyse detailed policy scenarios identifying the costs of the policies and their resulting benefits for improved local and regional water quality. We demonstrate the model's capabilities with a simple scenario where cover crops are incentivised with green payments over a large expanse of the watershed.

    The Economics of Dead Zones: Causes, Impacts, Policy Challenges, and a Model of the Gulf of Mexico Hypoxic Zone (2014)
    Oxford University Press
    Details
    Publication Date: 2014-01-28
    Description: This article reviews and analyzes the issues related to worldwide hypoxic zones and the range of economic questions sorely in need of answers. We begin by describing the extent and causes of hypoxic zones worldwide, followed by a review of the evidence concerning ecological effects of hypoxic zones and their impacts on ecosystem services. We describe what is known about abatement options and cost-effective policy design, and then focus on the large seasonally recurring hypoxic zone in the Gulf of Mexico. We offer a simple econometric model to estimate the relationship between pollutants (nutrients) and the size of the hypoxic zone. This "production function" relationship suggests that both instantaneous and historical nutrient contributions affect the size of the zone. Our results support concerns that ecologists have raised about lags in the recovery of the ecosystem and confirm the importance of multiple nutrients as target pollutants. We conclude with a discussion of the types of research and cooperation across disciplines that are needed to support the development of policies to address this important ecological and economic issue.
