THE ECONOMIC IMPACT OF GENETICALLY MODIFIED ORGANISMS IN SMALL DEVELOPING COUNTRIES AgEcon
Hareau, Guy Gaston; Mills, Bradford F.; Norton, George W.; Bosch, Darrell J..
The expected benefits from herbicide resistant transgenic rice in Uruguay are estimated with stochastic simulation techniques. Economic surplus methods that account for private profits are used to measure the magnitude and distribution of the benefits between producers and a multinational firm. Further, the adoption rate of transgenic rice is endogenous in the model and depends on the expected profitability of the technology. The results show that the potential benefits from the technology are relatively small because of the small production base. Multinational firms are, therefore, unlikely to develop locally adapted transgenic rice varieties without strategic partnerships with local institutions.

AN EVALUATION OF RISK MANAGEMENT STRATEGIES FOR DAIRY FARMS AgEcon
Bosch, Darrell J.; Johnson, Christian J..
Variability in feed prices and crop yields are important sources of risk to dairy farmers. A simulation model of a representative dairy farm was used to evaluate crop insurance and hedging as risk management strategies. These strategies lowered expected net returns but also reduced risk. The preferred set of strategies at lower levels of risk aversion included hedging and crop insurance, although a base scenario in which no risk management strategies were employed was also efficient. The preferred strategy at higher levels of risk aversion was a combination of crop insurance and hedging.

NONPOINT SOURCE AND CARBON SEQUESTRATION CREDIT TRADING: WHAT CAN THE TWO LEARN FROM EACH OTHER? AgEcon
Stephenson, Kurt; Bosch, Darrell J..
Emission trading programs have been discussed with respect to achieving water quality objectives and future caps on carbon emissions. A significant part of this literature explores the institutional and technical design issues associated with trades involving nonpoint effluent sources and carbon sequestration. This paper explores conceptual linkages between the nonpoint and carbon sequestration programs and identifies potential areas where cross fertilization can benefit research and policy design of trading programs for environmental protection.

Effects of Private Insurance on Forest Landowners' Incentives to Sequester and Trade Carbon under Uncertainty: Impact of Hurricanes AgEcon
Grover, Mansi; Bosch, Darrell J.; Preisley, Stephen P..
We evaluate incentives of forest landowners for sequestering and trading carbon, given the risk of carbon loss from hurricanes, and an opportunity to insure their losses. Results of simulation model reveal that the effect of hurricane risk depends on the variability of returns from carbon and timber and landowners' ability to mitigate risk by diversifying forest holdings across regions or transferring risk by purchasing insurance.

COMPENSATING IRRIGATORS FOR RESTRICTING WATER USE: AN EXPECTED UTILITY ANALYSIS AgEcon
Bosch, Darrell J.; Eidman, Vernon R.; Gill, Eric E..
A daily limitation on the number of hours irrigators can pump may be imposed by utility companies seeking to use the company's generating capacity more efficiently. Three power interruption patterns are analyzed to determine electricity cost reductions which would have to be offered to keep irrigators from being made worse off by the interruptions. Irrigation system pumping capacity and the irrigator's attitudes toward risk are found to be primary determinants of the size of the required reductions.

RISK AND SITE FACTORS AFFECTING POTENTIAL NITROGEN DELIVERY IN THE VIRGINIA COASTAL PLAIN AgEcon
Peng, Wei; Bosch, Darrell J..
The effects of cropland slope, distance to surface water, farmers' risk attitudes, and farmers' nitrogen (N) fertilizer applications on potential N delivery to streams and costs of reducing N delivery were evaluated for a representative Virginia peanut-cotton farm. Target MOTAD and generalized stochastic dominance were used to select preferred plans for different levels of risk aversion. Costs of reducing N delivery were lower on farms where fields were located close to surface water, where N was overapplied relative to extension fertilizer recommendations, and where the operator was risk averse. Cropland slope had less effect on cost of reducing N delivery relative to other factors.

Networking Your Way to a Better Prediction: Effectively Modeling Contingent Valuation Survey Data AgEcon
Bergtold, Jason S.; Taylor, Daniel B.; Bosch, Darrell J..
The purpose of this paper is to empirically compare the out-of-sample predictive capabilities of artificial neural networks, logit and probit models using dichotmous choice contingent valuation survey data. The authors find that feed-forward backpropagation artificial neural networks perform relatively better than the binary logit and probit models with linear index functions. In addition, guidelines for modeling contingent valuation survey data and how to estimate median WTP using artificial neural networks are provided.

Residential Land Values in Urbanizing Areas AgEcon
Kaltsas, Ioannis K.; Bosch, Darrell J.; McGuirk, Anya M..
Zoning decisions related to residential lot size and density affect residential land value. Effects of size on residential parcel value in Roanoke County, VA, are estimated with fixed effects hedonic models. Parcel size; elevation; soil permeability; proximity to urban areas, malls, and roads; and location influence parcel value, but the effects vary by value of construction and development status. Parcel value per square meter declines with increasing parcel size. The estimated relationships could be used to evaluate zoning decisions in terms of land values and tax revenues if model estimation uncertainties and responses by developers to zoning strategies are considered.

Causal Factors and Costs of Home Plumbing Corrosion: An Investigation of Sample Selection Bias AgEcon
Kleczyk, Ewa J.; Bosch, Darrell J..
High incidences of pinhole leaks, which occur in home plumbing due to pitting corrosion of water pipes, have been observed in parts of the U.S. such as the Maryland suburbs of Washington D.C. This research evaluates factors associated with pinhole leak occurrences and assesses the costs incurred by consumers from corrosion. Statistical analysis of Maryland survey responses suggests that the probability of pinhole leak occurrences is associated with the type of pipes installed and the distance of the dwelling from a water treatment plant. The number of leaks and location of pinhole leaks in the dwelling drive the financial costs of pinhole leak damage. Correcting for sample selection bias influences the estimated coefficients and statistical...

IMPACTS OF WITHIN-FARM SOIL VARIABILITY ON NITROGEN POLLUTION CONTROL COSTS AgEcon
Vandyke, Laura S.; Bosch, Darrell J.; Pease, James W..
The effects of considering variable within-farm soil runoff and leaching potential on costs of reducing nitrogen losses are analyzed for a Virginia dairy. Manure applications may cause nitrogen losses through runoff and leaching because of factors such as uncertain nitrogen mineralization. Farmers can reduce nitrogen control costs by applying manure on soils with less nitrogen loss potential. Ignoring within-farm soil variability may result in overstating the farm's costs of reducing nitrogen losses.

FARM ADVISORY SERVICES AND PESTICIDE TOXICITY ON COTTON AND PEANUTS IN THE ALBEMARLE-PAMLICO WATERSHED AgEcon
Mitra, Sonali; Bosch, Darrell J.; Taylor, Daniel B.; Pease, James W..
According to a Virginia-North Carolina watershed survey, farmers view advisory services as having the effect of decreasing pesticide use. However, analysis of pesticide use shows that hired staff, scouting personnel, and extension agents are associated with higher pesticide toxicity applied to cotton while chemical dealers and scouting personnel are associated with higher toxicity applied to peanuts.

Reducing Crop Nutrient Applications: The Yield Reserve Program AgEcon
Metcalfe, Todd; Bosch, Darrell J.; Pease, James W..
A proposed Yield Reserve Program designed to compensate farmers for any reduced yields resulting from reduced nitrogen (N) application rates below recommended rates is evaluated. Assuming that farmers currently follow extension recommendations for applying N, Yield Reserve Program participation reduces expected net revenue by $10 to $13/ha. The Yield Reserve Program reduces expected net revenue by $17 to $20/ha for farmers who apply N to maximize expected net revenue. Farmers’ costs of participation increase with lower probabilities of inadequate rainfall and higher corn prices and decline with higher N prices. The Yield Reserve Program can significantly reduce N applications to cropland, which may reduce N content of surface waters, but the costs to...

ECONOMIC RETURNS FROM REDUCING POULTRY LITTER PHOSPHORUS WITH MICROBIAL PHYTASE AgEcon
Bosch, Darrell J.; Zhu, Minkang; Kornegay, Ervin T..
Requiring that crop applications of manure be based on phosphorus content (P-standard) could increase poultry litter disposal costs. Microbial phytase reduces litter P content and could reduce litter disposal costs under a P-standard. For a representative Virginia turkey farm, phytase costs $2,500 and could increase value of litter used for fertilizer on the turkey farm by $390 and reduce supplemental P feed costs by $1,431. Based on assumed litter demand and supply, estimated litter export prices with phytase could exceed export prices without phytase by $3.81 per ton. Phytase net returns to the farm are an estimated $ 1,435.

USING SPATIAL INFORMATION TO REDUCE COSTS OF CONTROLLING AGRICULTURAL NONPOINT SOURCE POLLUTION AgEcon
Carpentier, Chantal Line; Bosch, Darrell J.; Batie, Sandra S..
Reducing costs of controlling nonpoint source (NPS) pollution will be a high public priority in the next century. Compliance and transaction costs of reducing nitrogen runoff from dairies in the Lower Susquehanna Watershed by 40% are estimated for perfectly targeted and uniform performance standards. The perfectly targeted standard reduces compliance and transaction costs by almost 75% compared with the uniform standard. Future NPS control policies should use spatial information to target policy resources to priority concerns, areas, and farms. Further research is needed to lower the costs and increase the accuracy of spatial information.

CARBON CREDIT POTENTIAL FROM INTENSIVE ROTATIONAL GRAZING UNDER CARBON CREDIT CERTIFICATION PROTOCOLS AgEcon
Stephenson, Kurt; Bosch, Darrell J.; Groover, Gordon E..
Rotational grazing can potentially reduce greenhouse gas (GHG) emissions from animal operations. This study investigates potential GHG reductions from rotational grazing farm operations under alternative procedures for defining a carbon credit. As applied to a case study cow-calf operation, GHG emission credits did not differ substantially under different definitions of entity boundaries. The choice of accounting metric used to report credits (mass load versus load per unit of output), however, would dramatically influence whether a farm would benefit financially from a future market in carbon credits.
