| The differential demand system or Rotterdam model is extended to include lagged consumption through translation parameters, allowing habit and inventory effects. Applications of the model to annual U.S. expenditure and weekly juice sales data illustrate the importance of the time interval of an observation on the relative strengths of the habit inventory. |

| The differential demand system or Rotterdam model is extended to include lagged consumption through translation parameters, providing an alternative to simply adding constant terms to the model to allow for trends in consumption and changes in tastes. Application of the model to four broadly defined groups of goods indicates significant lag effects, resulting in differences in short-run and long-run income and price responses. |

| Both a single equation model and Rotterdam demand system were used to estimate the impact of advertising on OJ demand. In the single equation model, OJ gallon sales were related to OJ advertising, grapefruit juice advertising, the price of OJ, seasonality variables, consumer income, and a dummy variable for September 11 to further capture possible effect resulting from changes in the U.S. economy and consumer confidence after that point in time. The impact of each of these variables was estimated by applying the ordinary least squares regression method to data from September 1997 to November 2001. The results suggest that recent decreases in OJ demand are related to declines in FDOC advertising, as well as perhaps declines in incomes and changes in... |

| In this study, an OJ model was developed to examine the optimal advertising-research mix to maximize Florida grower revenue net of the costs of these activities. The model is based on assumed coefficients reflecting the impacts of prices, advertising and research. The effects of prices on demand and supply, as well as the effect of advertising on demand, were set based on findings of prior studies. The effect of research on supply is less certain, and a range of research effects was considered. A range of advertising effects was also considered given the study’s focus. The model solutions for the various advertising and research assumptions considered indicate that optimal advertising expenditures are significant |

| 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. |

| In this paper, estimates of the impacts of various factors on the refrigerated OJ sales in Wal-Mart (WM) stores are presented. Data on WM stores, as well as grocery stores doing $2 million or greater annual business, across 52 Nielsen city markets (including the remaining U.S.) were studied. Since WM does not have stores in San Diego, this market was omitted. Weekly data for each city from week ending 3/11/06 through 3/01/08 (104 weeks) were included in the analysis. The relationship between WM refrigerated OJ dollar sales per store and 1) WM and $2million store prices, $2 million store promotions, a dummy variable to test whether sales may spike during periods when some consumers receive their paychecks (middle or end of the month), the number of same... |

| In this study we developed a health status index using the commonly recorded health measures by doctors and hospitals. This health status index has a minimum possible value of 7 (the least healthy) and a maximum value of 21 (the healthiest). Using the NHANES data, we explored the relationship of this health status index and nutrient intakes, lifestyle, and demographics of the respondent. Regression results showed that as the age of the respondent, being non-Hispanic black, participants of food stamp programs, high percent of calories that came from fat intakes, high percent of calories in beverages that came from soft drinks, smoking, and on special diets are negatively related to the value of the health status index (i.e., the person became less... |
