A QUALITATIVE CHOICE ANALYSIS OF FACTORS INFLUENCING POST-CRP LAND USE DECISIONS AgEcon
Johnson, Phillip N.; Misra, Sukant K.; Ervin, R. Terry.
The future use of Conservation Reserve Program (CRP) lands is an important agricultural policy issue. To examine the effects of factors that influence landowners' post-contract use of CRP lands, a survey of Texas High Plains CRP contract holders was conducted in 1992. This study analyzes the results of the survey using a qualitative choice model. It was found that the presence of a livestock enterprise in the current contract holder's operation increases the probability of these acres remaining in the established cover. Contract holders who value the commodity base have an increased probability of returning their acres to crop production.

ARE CROP YIELDS NORMALLY DISTRIBUTED? AgEcon
Ramirez, Octavio A.; Misra, Sukant K.; Field, James E..
This paper revisits the issue of crop yield distributions using improved model specifications, estimation and testing procedures that address the methodological concerns raised in recent literature that could have invalidated previous conclusions of yield non-normality. It shows beyond reasonable doubt that some crop yield distributions are non-normal, kurtotic and right or left skewed, depending on the circumstances. A procedure to jointly estimate non-normal farm- and aggregate-level yield distributions with similar means but different variances is illustrated, and the consequences of incorrectly assuming yield normality are explored.

Asymmetry, Risk, and Correlation Dynamics in the U.S. Fiber Market AgEcon
Fadiga, Mohamadou L.; Misra, Sukant K..
This study looked at the dynamics of conditional correlations and hedging strategies in the US main cotton producing regions. A two-step procedure was utilized to model, estimate, and analyze volatility, conditional correlations, and the optimal hedge ratios using spot prices in the Delta, Southeast, Southern Plains, and the Southwest regions and the New York commodity exchanges December futures contracts. The results indicate that volatilities in most of the regions are asymmetric and persistent. The derived conditional correlations and the optimal hedging ratios are dynamic although they do not have unit root. Moreover, the changes in agricultural policies altered the dynamics of correlations and producers' hedging strategies in the Delta, Southeast,...

Common Trends, Common Cycles, and Price Relationships in the International Fiber Market AgEcon
Fadiga, Mohamadou L.; Misra, Sukant K..
A multivariate unobserved component model was applied to identify common movements among cotton, wool, rayon, and polyester world prices. Two common stochastic trends and cycles govern the stochastic behaviors of price fluctuations in the world fiber market. These unobserved components have important implications as they can help in the design of more efficient commodity programs to smooth terms of trade shocks, especially in developing countries. The study found the effect of inventory adjustments on world cotton price is diminishing, which indicates that speculative behaviors in the world fiber market are less prevalent than previously thought.

CONSUMER WILLINGNESS TO PAY FOR PESTICIDE-FREE FRESH PRODUCE AgEcon
Misra, Sukant K.; Huang, Chung L.; Ott, Stephen L..
The study uses primary data collected from a survey conducted in Georgia to analyze consumer preferences for testing and certification of fresh produce and consumers' willingness to pay for fresh produce that is certified as free of pesticide residues (FPR). An ordered probit model was estimated to identify the impacts of various exogenous variables on the probability of consumers' willingness to pay for a number of alternative price premiums. The results indicate that consumers' willingness to pay differs with respect to a number of factors. The study concludes that most of the consumers recommend testing and certification, but they oppose large price markups for certified-FPR fresh produce.

Cost/Benefit Analysis of Bur Extractors in Cotton Harvesting AgEcon
Bennett, Blake K.; Misra, Sukant K.; Brashears, Alan.
The objective of this research was to estimate the effect of using bur extractors in cotton stripping on foreign material in harvested cotton, on both quality attributes and lint turnout, and to determine the minimum harvested acres a producer must have for a bur extractor to be cost effective. Results indicate that the bur extractor has significant effect in reducing bur percent, stick percent, and in increasing seed cotton percent and lint turnout, while is showed no statistically significant effect on any of the quality attributes. Results also suggest that investment in bur extractors is profitable for both irrigated and dryland cotton production situations with an operation of at least 750 acres. This study provides a simple method that can be...

Cotton Farmers' Technical Efficiency: Stochastic and Nonstochastic Production Function Approaches AgEcon
Chakraborty, Kalyan; Misra, Sukant K.; Johnson, Phillip N..
Technical efficiency for cotton growers is examined using both stochastic (SFA) and nonstochastic (DEA) production function approaches. The empirical application uses farm-level data from four counties in west Texas. While efficiency scores for the individual farms differed between SFA and DEA, the mean efficiency scores are invariant of the method of estimation under the assumption of constant returns to scale. On average, irrigated farms are 80% and nonirrigated farms are 70% efficient. Findings show that in Texas, the irrigated farms, on average, could reduce their expenditures on other inputs by 10%, and the nonirrigated farms could reduce their expenditures on machinery and labor by 12% and 13%, respectively, while producing the same level of output.

Demand for Milk Produced With and Without Recombinant Bovine Somatotropin AgEcon
Misra, Sukant K.; Clem, Kyle D..
This study focuses on the nature of Texas consumer perception and willingness to purchase milk produced using recombinant bovine somatotropin (rBST). Future, the possibility of market segmentation is analyzed by estimating the price sensitivity of consumer demand for conventionally produced milk versus rBST-produced milk. Results show that the price elasticities of demand for the two types of milk are different, indicating potential to develop niche markets for both rBST-produced and conventionally produced milk in Texas.

Efficient Refuge policies for Bt cotton in India AgEcon
Singla, Rohit; Johnson, Phillip N.; Misra, Sukant K..
This study examined the efficient refuge policies for Bt cotton for three cotton growing regions in India. This was accomplished by developing a single-pest, dual-toxin biological model simulating bollworm resistance to the Bt toxin and synthetic pyrethroids, followed by formulating profit functions for Bt and non-Bt cotton for a representative producer in each region. Profits received in subsequent periods were considered in the regulatory model in order to choose a refuge constraint (static problem) or a sequence of refuge policies (dynamic problem) for each region that maximize discounted profits received over 15 years, subject to various economic and biological constraints. Dynamic solutions for the regulatory problem were derived for each region using...

ESTIMATION OF EFFICIENT REGRESSION MODELS FOR APPLIED AGRICULTURAL ECONOMICS RESEARCH AgEcon
Ramirez, Octavio A.; Misra, Sukant K.; Nelson, Jeannie.
This paper proposes and explores the use of a partially adaptive estimation technique to improve the reliability of the inferences made from multiple regression models when the dependent variable is not normally distributed. The relevance of this technique for agricultural economics research is evaluated through Monte Carlo simulation and two mainstream applications: A time-series analysis of agricultural commodity prices and an empirical model of the West Texas cotton basis. It is concluded that, given non-normality, this technique can substantially reduce the magnitude of the standard errors of the slope parameter estimators in relation to OLS, GLS and other least squares based estimation procedures, in practice, allowing for more precise inferences...

Evaluating Crop and Revenue Insurance Products as Risk Management Tools for Texas Cotton Producers AgEcon
Field, James E.; Misra, Sukant K.; Ramirez, Octavio A..
This paper develops and illustrates the application of a procedure to evaluate and compare the cost effectiveness of alternative crop insurance products for cotton in terms of their effect on expected producer net returns and the variation of net returns. Farm unit-level cotton yields and state-level price distributions are estimated by a multivariate nonnormal parametric modeling procedure and used to simulate the net returns to alternative crop insurance products over a 10-year planning horizon. The ranking of alternative insurance products using third-degree stochastic dominance is presented for Texas cotton producers.

FACTORS INFLUENCING SOUTHERN DAIRY FARMERS' CHOICE OF MILK HANDLERS AgEcon
Misra, Sukant K.; Carley, Dale H.; Fletcher, Stanley M..
Survey data of 2,538 dairy farmers located in 12 southern states were used to analyze the factors influencing farmers' choice of milk handlers. Results from a qualitative response model indicate that a combination of price and non-price factors contribute to dairy farmers' attitudes toward their milk handlers. Specifically, the decision to change milk handlers was significantly influenced by prices paid and deductions charged. However, non-price factors including field services, friendly personnel, and loyalty to a handler contributed to the longer term affiliation of dairy farmers with their milk handlers.

Impact of efficient refuge policies for Bt cotton in India on world cotton trade AgEcon
Singla, Rohit; Johnson, Phillip N.; Misra, Sukant K..
India is a major cotton producing country in the world along with the U.S. and China. A change in the supply of and demand for cotton in the Indian market has the potential to have an impact on world cotton trade. This study evaluates the implications of efficient Bt cotton refuge policies in India on world and U.S. cotton markets. It can be hypothesized that increased refuge requirements for Bt cotton varieties in India could decrease the world supply of cotton because of the lower yield potential of non-Bt cotton varieties planted in refuges. A decrease in world cotton supply could potentially raise world cotton prices, ceteris paribus. This study conceptualizes the impact of efficient refuges in India on world cotton markets by using a partial...

INCORPORATING THE IMPACTS OF UNCERTAIN FIELDWORK TIME ON WHOLE-FARM RISK-RETURN LEVELS: A TARGET MOTAD APPROACH AgEcon
Misra, Sukant K.; Spurlock, Stanley R..
Given an equipment complement, a specific crop mix has a probability distribution for whole-farm net returns. Increasing crop acreage while holding the set of equipment constant will reduce fixed costs per acre, but it will also increase the length of time required to complete crucial field operations such as planting and harvesting. Thus, the probability of encountering weather-related delays in fieldwork will increase. This increase in delays may cause a decline in yields and changes in the distribution of net returns. This paper develops a Target MOTAD model capable of capturing intra-year impacts on profit that arise from the timing of planting and harvesting operations as well as inter-year impacts on profits that are due to variations in economic and...

MINIMIZING FARM-TO-MILL COTTON CLEANING COST AgEcon
Bennett, Blake K.; Misra, Sukant K..
This study focuses on least-cost farm-to-mill cotton cleaning configurations employing survey, regression, and simulation techniques. The resulting least-cost cotton cleaning configurations, employing standard textile technology, included the use of one lint cleaning in the ginning stage. The use of a field cleaner in the harvesting stage was also found to be optimal with some variation based on the desired yarn quality. Results of the study indicated that the optimal cleaning configurations were distinctly different from currently used practices, such that appropriate changes could save the cotton industry between $0.30 and $0.60 per bale of cotton, depending on the desired yarn quality.
