| Florida is typical of many southeastern states in that it exports feeder cattle and imports carcass and boxed beef. The objective of this paper is to estimate the cost of retaining feeder cattle in Florida, feeding these cattle to slaughter weights, slaughtering them, and distributing the meat to retail outlets. A mixed integer programming model is developed. The optimal number and location of feedlots and slaughter plants are determined. The results indicate that at production levels exceeding 600,000 head, the cost of producing carcass beef in the State is comparable to the average for the United States. |

| An analysis of a typical crop and livestock farm in North Florida is presented. The analysis incorporates the potential competition and complementarity among crop and beef cattle enterprises. A Target MOTAD model is developed to account for risk in a decision framework. The results indicate that when income risk is ignored, peanuts, watermelon, and stocker cattle are the only enterprises included in the optimal solution. When income risk is heavily weighted, the optimal solution includes peanuts, watermelon, stocker cattle, cow-calf, and irrigated soybeans. The results suggest that the persistence of cow-calf production may be explained as a stabilizer of income. |

| This study evaluates the economic impact of a ban on methyl bromide on the U.S. winter fresh vegetable market for six major crops: tomatoes, green peppers, cucumbers, squash, eggplant, and watermelons. Florida is the primary domestic supplier of these products. Mexico and Texas are the competing suppliers of the five vegetable crops and peppers, respectively. Leontief technologies represent both monocrop and double-crop production systems; linear inverse demand functions represent four demand regions in the U.S. and Canada. By increasing production costs and reducing yields, a ban on methyl bromide decreases Florida's FOB revenues by 54% and increases those of Mexico by 65%. Price increases to U.S. fresh vegetable consumers range from near zero to over... |

| Supermarket shelves are saturated with numerous varieties and brands of juice beverages. This high level of assortment has dramatically changed beverage consumption patterns and trends throughout the United States. In fact, during 2004-2005, energy and sport drinks experienced significant increases in sales, 65.9% and 20.6 %, respectively. During the same period of time, refrigerated juice sales increased a mere 2.2%, shelved non-fruit drinks decreased 0.9%, bottled juices and cocktails both decreased 1.5 % and frozen juice decreased by 12.8% (Food Industry Review 2006). The beverage industry has undergone many transformations, but consumer theory states that a shift in demand for one good has to be compensated by a shift in the opposite directions in the... |

| From 2000 through 2004, per capita orange juice purchases decreased by 12.3 percent while the popularity and media coverage of low-carbohydrate dieting exploded. Content analysis was used to count selected Southern region newspaper articles topically related to low-carbohydrate dieting, the Atkins diet, and the South Beach diet. This data was included in a Southern region orange juice demand model, where purchase data served as the independent variable and proxy for consumer demand of orange juice. Results indicated that media coverage of low-carbohydrate diets and dieting was negatively and significantly related to demand for orange juice in the Southern region. |

| This paper examines the potential benefits of introducing a new payment scheme in a sugarcane processing cooperative. Findings suggest that a use-value payment system would increase individual and total members’ net returns significantly over a sugar-based system. The proposed payment system would change the incentive structure so varieties with higher processing quality would become more appealing. In addition, the cooperative plant would be used more uniformly throughout the processing season and payments to members would be more consistent with their contribution to cooperative surplus. |

| The processed citrus industries of Sao Paulo, Brazil and Florida, United States collectively account for over 80 percent of world orange juice production. In recent years, both industries have been confronted with serious plant disease outbreaks. Porter’s Diamond framework is used to assess the strengths and weakness of the processed citrus industry in each country to confront the combined challenge of effectively combating these diseases while maintaining market competitiveness. Although Sao Paulo and Florida produce a similar product, the Porter’s Diamond framework reveals that there are significant differences in the organizational structure of the two industries. The article concludes with an analysis of how these differences will impact each... |

| The use of alternative probability density functions to specify risk in farm programming models is explored and compared to a traditional specification using historical data. A method is described that compares risk efficient crop mixes using stochastic dominance techniques to examine impacts of different risk specifications on farm plans. Results indicate that a traditional method using historical farm data is as efficient for risk averse producers as two other methods of incorporating risk in farm programming models when evaluated using second degree stochastic dominance. Stochastic dominance with respect to a function further discriminates among the distributions, indicating that a density function based on the historic forecasting accuracy of the... |
