A Two-Step Auction in the Presence of Negative Values: An Application to “Farm-Raised” Pre-Cooked Roast Beef 31
Nalley, Lawton Lanier; Hudson, Darren.
Uniform auctions are commonly used to elicit willingness to pay for new or novel products, product attributes, or non-market goods. However, most auctions or other contingent-valuation techniques do not allow for negative values, despite the fact that many consumers hold negative values for these products or product attributes. We conducted a WTP auction for a new product along with a within-sample WTA second auction allowing for negative responses. We find that failing to allow for negative values significantly inflates willingness to pay estimates and estimates of expected market share. This paper provides a method of incorporating negative values into auctions and willingness to pay elicitation.

ANÁLISIS DE BIENESTAR DE LOS “SHOCKS DE PRECIOS DE LOS COMMODITIES” EN LOS MERCADOS DE MAÍZ Y TRIGO EN MÉXICO 31
Barkley, Andrew P.; Nalley, Lawton Lanier; Garay, Pedro V..
The impacts of biofuel-based commodity price shocks on wheat and maize producers and consumers in Mexico are quantified with a two-region welfare economics model of the world wheat and maize markets. This model captures the international flow of wheat and maize between Mexico and the rest of the world, enabling measurement of price and quantity changes in both Mexican and global wheat and maize markets due to supply shocks in the grain markets. The drastic shifts in supply that accompanied grain markets in 2007/2008 are used to quantify the effects on Mexican consumer and producer well-being.

Consistency of Consumer Valuation Under Different Information Sets: An Experimental Auction with Sweet Potatoes 31
Nalley, Lawton Lanier; Hudson, Darren; Parkhurst, Gregory M..
We used a controlled, uniform 5th-price auction to elicit values for sweet potatoes—both when location is known and unknown, and before and after tasting and providing health information. Significant differences were found between pre- and post-consumption valuations and also found that there were significant effects for location of origin and health information. Interestingly, we also find that location of origin not only affects the level of bids, but also the marginal differences in bids between different potatoes. Overall, however, these results suggest little consistency in bid values across information sets, suggesting that attempting to elicit values of attributes in isolation may lead to erroneous results.

CREDENCE ATTRIBUTES, CONSUMER VALUATION, AND ENDOWMNET EFFECTS IN AUCTIONS: THE CASE OF SWEET POTATOES 31
Nalley, Lawton Lanier; Hudson, Darren; Parkhurst, Gregory M..
There have been few studies that examine valuations of location of origin before and after consumers have consumed the product (or health advertising). Results of non-hypothetical experiments show that knowledge of origin does have an impact on valuation as well as the taste attribute (experience) and the health attribute (credence).

Enhancing Farm Profitability through Portfolio Analysis: The Case of Spatial Rice Variety Selection. 31
Nalley, Lawton Lanier; Barkley, Andrew P.; Brad, Watkins; Hignight, Jeffrey A..
The objectives of this paper is to use the large depth of existing literature on portfolio theory and apply it to rice varietal selection for 6 counties in the Arkansas Delta. Results based on 1999-2006 data suggests that combining available varieties using portfolio theory could have increased profits from 3 to 26% (dependent on location) in the Arkansas Delta. The major implication of this research is that data and statistical tools are available to improve the choice of rice varieties to plant each year in specific locations within Arkansas. Specifically, there are large potential gains from combining varieties that are characterized by inverse yield responses to growing conditions such as drought, pest infestation, or the presence of a specific disease.

Enhancing Farm Profitability through Portfolio Analysis: The Case of Spatial Rice Variety Selection 31
Nalley, Lawton Lanier; Barkely, Andrew; Watkins, Brad; Hignight, Jeffrey A..
This study applies portfolio theory to rice varietal selection decisions to find profit maximizing and risk minimizing outcomes. Results based on data from six counties in the Arkansas Delta for the period 1999–2006 suggest that sowing a portfolio of rice varieties could have increased profits from 3 to 26% (depending on the location) for rice producers in the Arkansas Delta. The major implication of this research is that data and statistical tools are available for rice producers to improve the choice of rice varieties to plant each year in specific locations. Specifically, there are large potential gains from combining varieties that are characterized by inverse yield responses to growing conditions such as drought, pest infestation, or the presence of a...

Expected Changes in Farm Landscape with the Introduction of a Biomass Market 31
Popp, Michael P.; Nalley, Lawton Lanier; Vickery, Gina B..
This study examines how the introduction of dedicated energy crops—switchgrass and forage sorghum—may affect Arkansas’ crop allocation decisions. The study captures crop production practices at the county or crop reporting district level. Results are in a static equilibrium framework and limited to a one-year ahead forecast. The model’s predictive success was evaluated by comparing 2007 model results with no energy crop production to actual acreages harvested. Switchgrass entered land use at approximately $25 and $35/dry ton in 2007 and 2008, respectively. Higher 2008 commodity prices for traditional crops caused lower switchgrass acreage peaks compared to 2007. Further, at higher biomass price levels—$45 to $55/dry ton depending on year and whether or not...

Going, Going, Almost Gone: How the Depletion of the Alluvial Aquifer Will Affect Cropping Decisions in the Arkansas Delta 31
Popp, Michael P.; Nalley, Lawton Lanier; Vickery, Gina B..
The U.S. Geological Survey (USGS) has determined that agricultural irrigation in Arkansas’ Delta is unsustainable with significant negative economic repercussions on producers net returns affected by the Alluvial aquifer. This study examines how irrigation restrictions in that region would affect county net returns to crop production. It also considers the effect of planting less water-intensive bioenergy crops in the event biofuel markets become a reality. A constrained optimization model determines acreage allocations and net returns under three irrigation scenarios: i) no irrigation restrictions, ii) irrigation restrictions that lead to a sustainable Alluvial aquifer, and iii) irrigation restrictions that would lengthen the life of the Alluvial...

How A Cap-and-Trade Policy of Green House Gases Could Alter the Face of Agriculture in the South: A Spatial and Production Level Analysis. 31
Nalley, Lawton Lanier; Popp, Michael P.; Fortin, Corey.
With the Waxman-Markey Bill passing the House and the Obama administration’s push to reduce carbon emissions, the likelihood of the implementation of some form of a carbon policy is increasing. This study estimates the greenhouse gas (GHG) emissions of the six largest crops produced in Arkansas using 63 different production practices as documented by University of Arkansas Cooperative Extension Service. From these GHG estimates a baseline state “carbon footprint” was estimated and a hypothetical cap-and-trade carbon reduction of 5, 10, and 20% was levied on Arkansas agriculture. Results show that while a modest reduction in GHG emissions (5%) would only affect crop allocations amongst certain crops while marginally reducing state net returns, a 20%...

How a National Carbon Policy Could Affect Grain Variety Selection: The Case of Rice in Arkansas 31
McFadden, Brandon R.; Nalley, Lawton Lanier; Popp, Michael P..
This study conducts a life cycle assessment (LCA) of carbon emissions and estimates the carbon sequestered in 14 commonly sown rice varieties across the Arkansas Delta. Given the uncertainty regarding future carbon legislation, and increased consumer and industry demand for “greener” products, this study estimates how potential carbon policies would affect rice cultivar selection Hybrid rice varieties, given their higher yield and higher yield per unit of green house gas (GHG) emission, are better positioned to take advantage of any increase in consumer demand for “greener” products and/or absorb any government policy better than conventional rice cultivars.

Increasing Profitability of Small Scale Orchard Producers through Optimizing Replacement Rate: The Case Study of Ghana 31
Mahrizal; Nalley, Lawton Lanier; Dixon, Bruce L.; Popp, Jennie S. Hughes.
This study sets out to empirically estimate the optimum annual replacement rate and age of cocoa trees in order to maximize the net present value of four common cocoa production systems. The study examines the costs and returns of four common cocoa production systems in Ghana associated with changes in cocoa prices, fertilizer prices, inflation rates, and labor prices. While this study focuses on cocoa, the methodology is applicable to any perennial crop. This study uses empirical yield curves and cost of production data from Ghana to determine when and what percentage of a cocoa orchard should be replaced annually to maximize net present value of revenues over time. Successive versions of the model are solved to determine how input and output price...

In-Store Evaluation of Consumer Willingness to Pay for “Farm-Raised” Pre-Cooked Roast Beef: A Case Study 31
Nalley, Lawton Lanier; Hudson, Darren; Rogers, Robert W.; Martin, James M.; Herring, Joshua L..
A choice-based conjoint experiment was used to examine consumer willingness to pay for a farm-raised pre-cooked roast beef product. Consumers were contacted in a grocery store and provided a sample of the pre-cooked product. Findings indicate there is a small, but statistically significant willingness-to-pay premium for the farm-raised product, suggesting that some product differentiation may result in higher prices for these products. The study outlines an approach to marketing research.

Irrigation Restriction and Biomass Market Interactions: The Case of the Alluvial Aquifer 31
Popp, Michael P.; Nalley, Lawton Lanier; Vickery, Gina B..
The U.S. Geological Survey has determined that irrigation in Arkansas’ Delta is unsustainable. This study examines how irrigation restrictions would affect county net returns to crop production. It also considers the effect of planting less water-intensive bioenergy crops—switchgrass and forage sorghum—in the event biofuel markets become a reality. Results suggest that sustainable irrigation restrictions without bioenergy crops would decrease producer returns by 28% in the region. Introducing these alternative crops would both reduce groundwater use and may restore state producer returns, albeit with significant spatial income redistribution to crop production throughout the state.

Modeling Interactions of a Carbon Offset Policy and Biomass Markets on Crop Allocations 31
Popp, Michael P.; Nalley, Lawton Lanier.
Arkansas cropping pattern changes at the county level were estimated under various scenarios involving a likely decline in water availability, the development of a biomass market for renewable energy production, and the potential of a widely used carbon offset market. These scenarios are analyzed separately and jointly to determine which of the three scenarios is expected to have the largest impact on net (emissions – sequestration) greenhouse gas (GHG) emissions, renewable fuels feedstock supply, and producer net returns. Land use choices included conventional crops of rice, cotton, soybean, corn, grain sorghum, pasture, and hay. Specialty crops of loblolly pine and switchgrass were modeled for their respective potential to sequester carbon and provide...

Modeling the Effects of Cap and Trade and a Carbon Offset Policy on Crop Allocations and Farm Income 31
Nalley, Lawton Lanier; Popp, Michael P..
A static, producer profit maximization framework is used to capture county level land use choice on the basis of profitability, greenhouse gas (GHG) emissions to the farm gate as well as soil carbon sequestration as affected by tillage and soil type. Policy scenarios of a 5% GHG cap on agricultural emissions in conjunction with a carbon offset payment system, designed to provide producer payments for net carbon footprint (GHG emissions – soil carbon sequestration) reductions compared to a baseline are evaluated to determine potential changes to land use and or producer income as a result of different policy scenarios. Results suggest that a policy solely targeted at emissions can be counterproductive in the sense that acreage reductions of more...

Modeling the Structural Change in American Frozen Catfish Fillet Demand: An Analysis of Country of Origin Labeling and the Implementation of an Import Tariff 31
Nalley, Lawton Lanier.
This paper uses the Almost Ideal Demand System (AIDS) model to analyze two issues 1) The effect of the implementation of mandatory country of origin labeling and 2) the effect of the tariff on Vietnamese basa. The data would suggest that the first effort (COOL), in 2002, of the CFA to help protect domestic production may have actually had adverse effects. That is, by mandating that Vietnamese catfish be labeled as basa, a new market was created. This new market seems to have favorably differentiated the Vietnamese product from the American product. The second attempt to protect the domestic industry was to implement a tariff on all imports in February 2003. Since the market had been segmented by the mandatory COOL (2002) before the tariff implementation...

The Genetic and Economic Impact of the University of Arkansas’s Rice Breeding Program: 1983–2007 31
Nalley, Lawton Lanier; Moldenhauer, Karen A.; Lyman, Nathaniel.
This study estimates the proportion of rice yield increase in University of Arkansas Division of Agriculture’s (UofA) released rice cultivars that are attributable to genetic improvements through the University’s breeding program. Test plot data from eight UofA experiment stations were used to quantify the yield increases and potential yield growth decreases over time. In addition to quantifying the yield and yield variance evolution at the UofA, this study also calculates the economic benefits of the UofA rice breeding program. Results indicated that by releasing modern rice cultivars, the UofA rice breeding program increased average producer yield by 0.68 bu/ac annually. During the last decade, 1997–2007, the average annual economic benefits were 34.3...
