| This paper examines several approaches to introduce advertising in systems of demand equations. Advertising is included in the Rotterdam model using an unrestricted specification and three restricted specifications - advertising affects demand alternatively through (1) marginal utilities as in studies by Duffy (1987, 1989, 1990) and Selvanathan (1989), (2) scaling parameters which can be viewed as indicators of product quality, and (3) translation parameters which can be viewed as indicators of basic needs. A test to choose among the alternative specifications is provided and the methodology is applied to data on demand for fruit juice products. |

| The question of endogeneity of conditional expenditures, as well as prices, in conditional demand equations for justices is examined. Both conditional expenditures and prices were found to be uncorrelated with the conditional demand errors, based on Wu-Hausman tests. Conditional demand error variance/covariance estimates and corresponding Slutsky coefficient estimates were approximately proportional, as predicted by the theory of rational random behavior, further supporting independence of conditional expenditures and conditional errors for juice demands. |

| This study explored the roles of nutrients in the demand for food through utility theory. The findings support the argument that nutrients play important roles in the demand for food. The 1987-88 Nationwide Food Consumption Survey data were used. The impacts of six nutrients (carbohydrates, fats, vitamins, minerals, digestible fibers, and proteins) on the demand for five food groups (dairy, meats, vegetables and fruits, grain products, and other foods) were studied using the Rotterdam demand system. |

| This study incorporates quality into the Rotterdam demand system based on utility theory. Quality was modeled through its impact on marginal utility via perceived prices, following theoretical work by Basemann and Barten, among others. Results show that the price elasticity of fresh grapefruit demand is near unitary at the retail level and juice content has had relatively large impacts on fresh grapefruit demand. |

| This study considers the allocation of Florida citrus‐grower money between advertising and research programs to maximize grower revenue net of program costs. The allocation depends on the impact of advertising on demand and the impacts of research on the cost of production and supply. A number of studies have estimated the impact of advertising on OJ demand, but little is known about the impact of research. Research on citrus greening, a disease that has no known cure, is examined in the present study. There are no past studies to reliably gauge the impact of this research. The approach taken here is to ask if a given amount of research dollars is needed to reduce average production costs by certain amount, then what should be spent on advertising based on... |

| 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. |

| Estimates of a conditional demand system for twelve beverages, based on the Rotterdam model subject to a full, first-order autoregressive process, are discussed. Impacts of beverage prices, total beverage expenditures and promotions on beverage quantities demanded are provided. The results indicate that all beverages were normal goods; the majority had price elastic demands; most had a relatively large own-promotion effect; and a number of significant cross-promotional effects exist, indicating a relatively high level of competition for market share among the beverages studied. |

| This study uses the household production theory to study the demand for nutrients, i.e., households purchase a combination of food items from the market and produce the needed nutrients from these food items. By following the traditional household production approach, shadow prices for nutrients in food consumption are calculated. The cost function that generates the shadow prices appears plausible in terms of its elasticities of substitution and factor demand. After obtaining the calculated shadow prices of nutrients, the nutrient demand functions are estimated. Results show that the own-price elasticity of demand for nutrient is inelastic, whereas the expenditure elasticities indicate that nutrients are normal goods. Crossprice elasticities show that... |
