Nutrient Trading, the Flush Tax, and Maryland's Nitrogen Emissions to the Chesapeake Bay AgEcon
Hanson, James C.; McConnell, Kenneth E..
We investigate nutrient trading for point and non-point sources for the Bay Restoration Fund in Maryland. We demonstrate how to use the proceeds from the tax revenue to mimic trading high-cost upgrades of sewage treatment plants for low-cost winter cover crops. Under an optimistic assumption about costs for non-point sources, we calculate that abatement could be increased by more than 50%, while in a pessimistic scenario, abatement could be increased by 2%. We also explore the role of uncertainty in determining the appropriate trading ratio between point and non-point sources of pollution, showing that the higher uncertainty associated with non-point sources should induce a lower trading ratio.

Cost-Effective Farm-Level Nitrogen Abatement in the Presence of Environmental and Economic Risk AgEcon
Ekman, Sone.
This paper evaluates the consequences of considering environmental and economic risk in the analysis of cost-effective nitrogen abatement options in crop production. A farm-level mathematical programming model incorporating nitrogen leaching variability, field time variability, yield variability, and output price variability is developed. The empirical results reveal that requiring a high reliability with respect to a desired abatement target can be extremely costly, due to the high variability of nitrogen emissions. It appears to be sufficient to reduce average nitrogen load in order to reduce the environmental risk associated with nitrogen leaching variability, since a change to crops with lower average load also results in lower variability of nitrogen...

Simulated Trading for Maryland's Nitrogen Loadings in the Chesapeake Bay AgEcon
Hanson, James C.; McConnell, Kenneth E..
We investigate nutrient trading for point and non-point sources for the Bay Restoration Fund in Maryland. We demonstrate how to use the proceeds from the tax revenue to mimic a market by trading high-cost upgrades of sewage treatment plants for low-cost winter cover crops. Under an optimistic assumption about costs for non-point sources and naïve assumptions about the lag from planting cover crops to changes in nitrogen load, we calculate that 100 percent of abatement could be achieved at 56 percent of total costs, while in a pessimistic scenario, 100 percent of abatement could be could be achieved at 83 percent of total costs.
