| This report provides fresh grapefruit import data regarding European Union 15 (EU-15) and an in-depth look into the share changes for fresh grapefruit imports by country of origin during the period from 1989 through 2006. The Rotterdam demand system was used to study the relationship among the fresh grapefruit imported by the EU-15 from several major Northern Hemisphere grapefruit producing countries. Results suggest that when Florida’s grapefruit industry recovers from the damages caused by hurricanes and diseases, price would decrease and exports to the EU-15 would expect to increase. |

| The paper focuses on separability in the almost ideal demand system (AIDS) in time series analysis. The AIDS approximation based on Stone's price index is specified in terms of the Rotterdam model and block additivity is imposed for illustrative purposes. A generalization to other types of separability is then considered. The model can be viewed as an extension to Theil et al.'s Working-PI time series model. In both the Theil et al. model and the AIDS model examined here, the marginal propensity to spend on a good is allowed to depend on the good's budget share. In the model in this paper, the Slutsky coefficients are further allowed to depend on the budget shares. The model provides a consistent way to analyze subgroup demand relationships. |

| In this study, we examine the impacts of retail promotions and flu/cold incidences on the demand for orange juice using weekly Nielsen grocery orange juice sales statistics and the flu/cold incidences reported by Surveillance Data Inc. The cross-section time-series pooling technique proposed by Parks was used to estimate the demand parameters. Results show that flu/cold incidences increased the effectiveness of retail promotions on the demand for orange juice. |

| A model is developed to explain Florida citrus planting levels by variety. The varietal choice is based on the expected prices and price variances/covariances of the varieties under consideration. Overall planting returns are maximized for a given level of price risk. The model's price coefficients are similar to those of the Theil and Barten Rotterdam demand model. As in the Rotterdam model, both absolute and relative price coefficient specifications are considered, allowing an examination of restrictions related to the price risk. The empirical analysis considers two restricted specifications -- a varietal independence model, based on the assumption that only the price variances are important for predicting planting levels, and a group independence... |

| The link between high U.S. obesity rates and the overconsumption of added sugars, largely from sodas and fruit drinks, has prompted public calls for a tax on caloric sweetened beverages. Faced with such a tax, consumers may reduce consumption of these sweetened beverages and substitute nontaxed beverages, such as bottled water, juice, and milk. This study estimated that a tax-induced 20-percent price increase on caloric sweetened beverages could cause an average reduction of 37 calories per day, or 3.8 pounds of body weight over a year, for adults and an average of 43 calories per day, or 4.5 pounds over a year, for children. Given these reductions in calorie consumption, results show an estimated decline in adult overweight prevalence (66.9 to 62.4... |

| Import demand equations are estimated in order to identify the own-, cross-price, and volume elasticities that can be used to determine the best marketing strategy to increase U.S. orange juice gallons in the Canadian import market. This study uses the firm’s version of production differential, AIDS, CBS, and NBR models. An expansion of total Canadian orange juice import gallons using advertising favors the U.S. much more than it does the other three origins investigated— Brazil, Mexico, and ROW. A 1% increase in imported gallons of orange juice due to advertising will increase U.S. imports by 1.20% and Brazil’s gallons by 0.60%. |
