Climate policy poses a dilemma for environmental economists. The economic argument forstringent greenhouse gas (GHG) abatement is far from clear. There is disagreement amongboth climate scientists and economists concerning the likelihood of alternative climateoutcomes, the nature and extent of the uncertainty of those outcomes, and the frameworkthat should be used to evaluate po...
The threat of invasive species stems from their ability to rapidly and irreversibly change ecosystems and degrade the value of ecosystem services. Optimal control of a pre-established exotic pest minimizes the costs of population reduction plus the residual damages from the remaining pest population. The shrubby tree, Miconia calvescens, is used to illustrate dynamic policy options for a forest...
This study explores the relationship between happiness and air pollution in Britain using data from the British Household Panel Survey (BHPS). The effects of air pollution on individuals’ happiness are estimated and their monetary value is calculated. In particular, three air pollutants are examined in this paper; the sulphur dioxide (SO2), the ground-level ozone (O3) and the nitrogen dioxides ...
In this article we develop a simulation model for estimating the economic efficiency of fuel treatments and apply it to two sagebrush ecosystems in the Great Basin of the western United States: Wyoming Sagebrush Steppe and Mountain Big Sagebrush. These two ecosystems face the two most prominent resource management concerns in sagebrush ecosystems relative to wildfire: annual grass invasion and ...
This study applies functional Benefit Transfer via Meta-Regression Modeling to derive valuation estimates for wetlands in an actual policy setting of proposed groundwater transfers in Eastern Nevada. We illustrate how Bayesian estimation techniques can be used to overcome small sample problems notoriously present in Meta-functional Benefit Transfer. The highlights of our methodology are (i) The...
The United States Government recently developed a range of values representing the monetized global damages associated with an incremental increase in carbon dioxide (CO2) emissions, commonly referred to as the social cost of carbon (SCC). These values are currently used in benefit-cost analyses to assess potential federal regulations. For 2010, the central value of the SCC is $21 per ton of CO...
In many stated preference settings stakeholders will be uncertain as to their exact willingness-topay for a proposed environmental amenity. To accommodate this possibility analysts have designed elicitation formats with multiple bids and response options that allow for the expression of uncertainty. We argue that the information content flowing from such elicitation has not yet been fully and e...
