A Choice-Based Conjoint Experiment with Genetically Engineered Cotton in the Mississippi Delta AgEcon
Banerjee, Swagata (Ban); Martin, Steven W.; Hudson, Darren.
Producers' preferences for cottonseed are examined using a willingness-to-pay (WTP) approach via mail surveys. Results indicate a positive WTP for yield, technology and fiber quality, and it increases with the level of technology and quality, respectively. WTP varies directly with farm size and inversely with farm labor.

A Comparison Of Choice Experiments And Actual Grocery Store Behavior: An Empirical Application To Seafood Products AgEcon
Hudson, Darren; Gallardo, Rosa Karina; Hanson, Terrill R..
In this paper we compare results from an in-store field experiment and a mail survey choice experiment (CE) to investigate CE’s capacity in predicting grocery store market share. For the comparison, we used three seafood products: freshwater prawns, marine shrimp, and lobster. CE estimates were obtained via four econometric models: the conditional logit, the random parameter logit, the heteroskedastic extreme value, and the multinomial probit. We found that the level of control in the grocery store experiment and the choice of econometric model influenced the capacity of CE to predict grocery store market shares.

A MODEL OF ENTRY-EXIT DECISIONS AND CAPACITY CHOICE UNDER DEMAND UNCERTAINTY AgEcon
Isik, Murat; Coble, Keith H.; Hudson, Darren; House, Lisa.
Many investment decisions of agribusiness firms such as when to invest in an emerging market or whether to expand the capacity of the firm involve irreversible investment and uncertainty about demand, cost or competition. This paper uses an option-value model to examine the factors affecting an agribusiness firm's decision whether and how much to invest in an emerging market under demand uncertainty. Demand uncertainty and irreversibility of investment make investment less desirable than the net present value (NPV) rule indicates. The inactive firm is more reluctant to enter the market when it takes into account demand uncertainty because it preserves the opportunity of making a better investment later. The active firm is more reluctant to abandon the...

A New Taxonomy of Thin Markets AgEcon
Anderson, John D.; Hudson, Darren; Harri, Ardian; Turner, Steven C..
The traditional conception of a thin market based on transactions volume remains relevant in many agricultural markets but does not adequately frame emerging thin market issues. As non-price means of pricing goods becomes more common, some cash commodity markets have become residual markets. In some of these markets, not only the volume of transactions but also the representativeness of transactions to those on the related contract market is an important issue. This paper develops a concept of thin markets that accounts for this dimension of market thinness and proposes a research agenda related to this topic.

A Note on Price Information in Commodity Markets with Evidence from the Cotton Market AgEcon
Hudson, Darren; Ethridge, Don E.; Segarra, Eduardo.
Theory and analysis of price information and its importance have typically assumed that the information is correct. Additionally, most analyses have centered on general price information assuming homogeneous products. This paper examines the implications of incorrect price information on the basis of quality, with evidence from prior research on cotton prices used as an illustration. Results of a conceptual analysis indicate that quality has direct implications on the production and marketing process. Incorrect information on prices of different quality leads to distortions in the market and market inefficiency.

A PRELIMINARY ECONOMIC ASSESSMENT OF ROUNDUP READY SOYBEANS IN MISSISSIPPI AgEcon
Couvillion, Warren C.; Kari, Fatimah; Hudson, Darren; Allen, Albert J..
The advent of genetically altered seed has had a revolutionary effect on the cotton, soybean, and corn seed industries. The basic premise for the use of these seed are to reduce costs through lower applications of chemicals and savings on trips through the field, thus, lowering production costs. Seed companies, however, charge a premium and a fee for use of the seed. This paper compares the costs associated with conventional and roundup ready soybeans. Data were collected from the ACost of Production@ survey of Mississippi producers that is administered by Mississippi State University through the National Agricultural Statistics Service. The survey is a random sample of producers fields that allows for a derivation of the cost of production for each field....

A Two-Step Auction in the Presence of Negative Values: An Application to “Farm-Raised” Pre-Cooked Roast Beef AgEcon
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.

Activists and Corporate Behavior in Food Processing and Retailing: A Sequential Bargaining Game AgEcon
Hudson, Darren; Lusk, Jayson L..
This study examines the strategic interaction between food companies and activists using a game theoretic model of sequential bargaining in the absence of complete information. In a rather confined set of circumstances, findings indicate it is always in the best interest of the food company to comply with activists' demands. More frequently, however, there will be cases where compliance is not optimal, depending on the size of the expected effect of protest, cost of defending against protest, and the cost of protest to the activist.

ADOPTION OF PRECISION AGRICULTURE TECHNOLOGY IN MISSISSIPPI AgEcon
Hudson, Darren; Hite, Diane.
Precision application technology has been an important topic in agriculture in recent years. This technology has the promise to improve farm management through improved information and control over in-field variability of soil characteristics and productivity. Despite this apparent promise, recent studies have shown that adoption has been low. However, little is known about the adoption of this technology in Mississippi or the reasons for or against adoption as seen through the eyes of the producer. This survey was designed to collect basic information on producer perceptions about precision agriculture technology and to assess potential reasons for or against adoption.

AN AUTOMATED ECONOMETRIC APPROACH FOR ESTIMATING AND REPORTING DAILY COTTON MARKET PRICES AgEcon
Brown, Jeff E.; Ethridge, Don E.; Hudson, Darren; Engels, Carlos.
An automated price reporting system developed through computer technology and hedonic price theory is used to estimate daily cotton market prices, premiums, and discounts. This objective approach for reporting cotton market prices was developed to complement the objective measures of high volume instrument grading of cotton. The computerized, econometric system is limited to the Texas and Oklahoma marketing regions where sales are readily available from electronic markets. The econometric based system has shown all the characteristics of an efficient price reporting system; it is accurate, reliable, consistent, and repeatable in its working process and price estimates.

Can We Predict Student Success in Agricultural Economics Graduate Programs? AgEcon
Ethridge, Don E.; Hudson, Darren.
Criteria for admission to graduate programs are used by departments and graduate schools to identify characteristics assumed to be associated with “success”. They allow for more uniformity in student ability and preparation so graduate education is more efficient. This study analyzes the relationship between selected student characteristics and experience and two proxies for “success”—graduate GPA and the probability of completing an Agricultural Economics graduate program. Data are from past students in the Department of Agricultural Economics at Texas Tech University. Statistical differences among the means of student characteristics were evaluated, a regression model was estimated to predict graduate GPA, and a logistical regression was estimated to...

Changes in Price Behavior in the U.S. Catfish Industry: Evidence Using Cointegration AgEcon
Hudson, Darren.
The implications of market development in the catfish industry on catfish price behavior are explored using cointegration. It is hypothesized that market development, through increases in competition between processors and shifts in consumer preferences toward fish, has caused changes in price behavior among levels of the catfish market. Using monthly catfish price data, a cointegration analysis of subsets of prices shows that price behavior has changed through time, with catfish prices becoming integrated as the number of processors has increased. These results may have implications for the examination of market price behavior in developing or emerging markets.

Comparison of Stated Choice and In-store Experimental Methods in Predicting Actual Market Behavior for Freshwater Prawn (Macrobrachium rosenbergii) Consumers AgEcon
Gallardo, Rosa Karina; Hanson, Terrill R.; Hudson, Darren.
The stated choice (SC) and actual revealed pricing/purchase experimental methods were compared for their ability to predict purchasing behavior and willingness-to-pay for freshwater prawns. SC hypothetical bias may be a consequence of difficulties in controlling factors affecting real world situations, small sample sizes and confusion related to the new product.

Consistency of Consumer Valuation Under Different Information Sets: An Experimental Auction with Sweet Potatoes AgEcon
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.

CONTRACTING IN AGRICULTURE: A PRIMER FOR FARM LENDERS AgEcon
Hudson, Darren.
Contracting in agriculture has increased over the past several decades. This activity has heightened concerns about concentration, market power, and farmer welfare. The purpose of this paper is to describe some of the underlying motivations for contracting and to highlight some of the trade-offs made when making contracting decisions. These illustrations are intended to inform readers of the economic conditions for contracting, not provide empirical evidence of their implications, costs, or benefits.
