AN ANALYSIS OF THE ECONOMIC IMPACT OF WATER TRANSFERS FROM AGRICULTURAL TO URBAN USES AgEcon
Sperow, Mark.
A two stage nonlinear optimization model was developed to account for the major surface and groundwater hydrologic features and cropping patterns in Colorado’'s San Luis Valley. Conjunctive use of surface and groundwater is included to assess changes in crop patterns and producer income from water exports outside the valley.

AN ECONOMIC ANALYSIS OF PASTURE-RAISED BEEF SYSTEMS IN APPALACHIA AgEcon
Evans, Jason R.; D'Souza, Gerard E.; Sperow, Mark; Rayburn, Edward B..
Cow-calf operations are important enterprises for family farmers in Appalachia and provide significant opportunity for supplemental income. This analysis constitutes a thorough economic assessment of pasture-raised beef production, an alternative to traditional production that could benefit the region's producers in terms of profitability and mitigated risk. Stochastic budgeting was utilized for profitability and risk comparison between traditional and pasture-raised operations and accounted for seasonal variability in prices, pasture availability and animal performance. Pasture-raised systems, in relation to traditional ones, were shown to consistently yield higher returns over variable costs and were shown less likely to yield losses over total costs...

Determining Consumer Perceptions of and Willingness to Pay for Appalachian Grass-Fed Beef: An Experimental Economics Approach AgEcon
Evans, Jason R.; D'Souza, Gerard E.; Collins, Alan R.; Brown, Cheryl; Sperow, Mark.
The focus of the current study was on the market potential for grass-fed beef in the Appalachian region, given that these products embody observed, experiential, nutritional, and process attributes that may appeal to a large consumer base. An in-store variant of the Becker-DeGroot-Marschack experimental auction mechanism was employed in the region to determine consumer preferences and willingness to pay. A majority of respondents preferred the grass-fed product over conventional grain-fed samples and were willing to pay a price premium to obtain it. Preferences for grass-fed were rooted largely in the associated superior nutritional content and core observed attributes.

Determining Consumer Perceptions of and Willingness to Pay or Appalachian Grass-fed Beef: An Experimental Economics Approach AgEcon
Evans, Jason R.; Brown, Cheryl; Collins, Alan R.; D'Souza, Gerard E.; Rayburn, Edward B.; Sperow, Mark.
The U.S. market for commoditized beef is a dynamic one that has, over the last 30 years, seen decreases in per capita consumption and an increased reliance on large, integrated feedlot facilities that focus on efficient weight gain and producing carcasses deemed desirable according the USDA quality grading system. Because of the problems inherent in the conventional production system and the existence of farm-to-retail price spreads that do not favor primary cow-calf producers, analyses of alternative beef production and marketing strategies that facilitate enhanced profitability and simultaneously address surging consumer demand for specialty food products are necessary. To that end, focus of the current study was on the market potential for grass-fed...

Economic Feasibility of a Woody Biomass- Based Ethanol Plant in Central Appalachia AgEcon
Wu, Jinzhuo; Sperow, Mark; Wang, Jingxin.
A mixed-integer programming model is developed to assess the economic feasibility of siting a woody biomass-based ethanol facility in the central Appalachian hardwood region. The model maximizes the net present value (NPV) of a facility over its economic life. Model inputs include biomass availability, biomass handling system type, plant investment and capacity, transportation logistics, feedstock and product pricing, project financing, and taxes. Four alternative woody biomass handling systems, which include all processes from stand to plant, are considered. Eleven possible plant locations were identified based on site selection requirements. Results showed that the optimal plant location was in Buckhannon, West Virginia. The NPV of the plant with a...

ECONOMICS OF SEQUESTERING CARBON IN THE U.S. AGRICULTURAL SECTOR AgEcon
Lewandrowski, Jan; Peters, Mark; Jones, Carol Adaire; House, Robert M.; Sperow, Mark; Eve, Marlen; Paustian, Keith H..
Atmospheric concentrations of greenhouse gases can be reduced by withdrawing carbon from the atmosphere and sequestering it in soils and biomass. This report analyzes the performance of alternative incentive designs and payment levels if farmers were paid to adopt land uses and management practices that raise soil carbon levels. At payment levels below $10 per metric ton for permanently sequestered carbon, analysis suggests landowners would find it more cost effective to adopt changes in rotations and tillage practices. At higher payment levels, afforestation dominates sequestration activities, mostly through conversion of pastureland. Across payment levels, the economic potential to sequester carbon is much lower than the technical potential reported in...

Estimating the Economic Value of Temporary and Permanent Carbon Sequestration Activities on Agricultural Land AgEcon
Sperow, Mark.
This paper estimates the value of carbon from soil sequestration and emission reductions from setting aside highly erodible land. Increases in soil carbon are estimated using the Intergovernmental Panel on Climate Change soil organic carbon inventory method and NRI data. Emission reductions are estimated using fuel use data from USDA-ERS.

Potential Carbon Sequestration and Revenue from Timber and Carbon Credits for Landowners of West Virginia Abandoned Mine Lands. AgEcon
Bouquot, Chris; Sperow, Mark.
An optimal forest rotation model estimates potential value from timber and carbon for owners of WV abandoned mine lands (AMLs). An OLS regression provides merchantable volume and carbon density for six forest types which could sequester 0.41 Tg of carbon per year on approximately 33,800 hectares of AMLs.
