Policies that aim to mitigate water pollution from fertilizer use in agriculture include input-based and output-based policies. Both cost-effectiveness and the speed for policies to take effect are important for policy assessment. In this study, we found that fertilizer price policies cannot...

In Mexico, farmers only pay the cost of electricity used to pump groundwater from wells for groundwater consumption and also receive electricity subsidy from government. It causes the fact that farmers consume groundwater under the situation that private marginal cost is lower than social...

The biofuel industry has been rapidly growing around the world in recent years. Several papers have used general equilibrium models and addressed the economy-wide and environmental consequences of producing biofuels at a large scale. They mainly argue that since biofuels are mostly produced from...

One argument in favor of market based pollution control policies is sometimes exaggerated, and a different argument is usually ignored. Regardless of whether investment is fixed or endogenous, market based policies might lead to a higher or lower equilibrium abatement compared to the level under...

The dynamic relationships among trade, income and the environment for developed and developing countries are examined using a cointegration analysis. Results suggest that trade and income growth tend to increase environmental quality in developed countries, whereas they have detrimental effects...

Phytase represents a potential win/win management practice for non-ruminant producers since it can reduce the need for phosphorous supplementation and also result in lower phosphorous runoff. Cost of phytase has decreased and cost of phosphorous has increased. The reported adoption rate for...

Once established, invasive species can rapidly and irreversibly alter ecosystems and degrade the value of ecosystem services. Optimal control of an exotic pest solves for a trajectory of removals that minimizes the present value of removal costs and residual damages from the remaining pest...

Many conservation programs, such as the Conservation Reserve Program (CRP), use indices to select offers. When modeling how changes in the index weights effect program outcomes, one must account for the attributes of available land, and which landowners chose to participate. This paper...

Land-use change is arguably the most pervasive socioeconomic force driving the change and degradation of watershed ecosystems. This paper combines an econometric model of land use choice with three models of watershed health indicators (conventional water pollution, toxic water pollution, and...
