| 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,... |

| 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. |

| 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... |

| 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. |

| 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... |

| 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... |

| 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... |

| 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. |
