A multiobjective bioeconomic policy model was developed for the United States Pacific whiting fishery. Pareto-optimal solutions for three policy objectives—rents, production, and female spawning biomass—were developed and analyzed using "hybrid" generating technique. Three policy instruments...

Most terrestrial biological invasions occur in landscapes comprising numerous, independently managed properties. Thus, control of invasion spread generally depends on the choices of many managers, each deciding the extent to control invasions on their property. Here we develop a...

Agricultural production can degrade water sources through leaching of nitrogen and phosphorus from agricultural land to surface and ground water sources. To minimize the pollution from agricultural production, the U.S. Department of Agriculture promotes adoption of conservation practices....

In this paper, we set up a social cost minimization problem for a government. Using dynamic optimization tools, we analytically shows how exogenous parameters could affect the optimal social cost and the optimal tax credit policy path.

A class of dynamic models is developed to assess potential gains from management of groundwater in arid and semi-arid regions in the presence of technical change. The aquifer is a common-pool resource (CPR) because users typically hold the right to pump groundwater but do not own the water...

Many invaded ecosystems appear subject to regime shifts—abrupt changes from one state to another after crossing a threshold or tipping point. The stability landscapes of such multi-stable systems, including their associated thresholds, have been shown to be endogenously determined within a...

In many areas of developing countries, economic and institutional factors often combine to give farmers incentives to clear forests and repeatedly plant food crops without sufficiently replenishing the soils. These activities lead to large-scale land degradation and contribute to global warming...

Abstract Bromus Tectorum is an invasive plant species known to reduce abundance of native perennial grasses, increase fire frequency and intensity, decrease animal performance, and alter microbial communities and ecosystem processes. Specifically, in the Intermountain West, Bromus has been...
