| Preference variables are included in the inverse Rotterdam model based on the Tintner-Ichimura-Basmann relationship linking preference effects on quantities demanded to price effects and preference effects on marginal utilities. Restrictions are made on the effects of the preference variables on the marginal utilities, resulting in reductions in the parameter space for the preference variables in both direct and inverse demand systems. The model is used to analyze impacts of product quality on fresh citrus demand. |

| An extension of the differential demand system model is developed that allows the demand system’s income and price responses to vary with income level. The model’s income flexibility and marginal propensities to consume (MPCs) out of income are made functions of real income measured by the Divisia volume index. The income flexibility is a factor of proportionality underlying all price effects and a change in this term impacts the sensitivity of all demands to prices. Price effects are also made a function of the MPCs using a uniform substitute specification. The model was used to analyze the conditional demands for a group of beverages. The findings indicate that changes in conditional total beverage expenditures result in various income and price... |

| 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... |

| This study examined the relationship between the unemployment rate and the demand for OJ. Based on the demand estimates obtained, the hypothesis that unemployment is having a significant negative impact on OJ demand cannot be refuted. Over the sample period, the unemployment rate increased by about 4.5 points, resulting in a 7.7% to 12.6% decline in OJ demand, based on the alternative model estimates. The unemployment rate, however, has trended upward in recent years, raising the possible that it may be reflecting to some extent the impact of other trend related factors such as preferences for reduced calories. |

| A recent study by Dong and Leibtag found coupons were effective in increasing fruit and vegetable demand. The current study supports these finding for the OJ product group. The analysis focused on the informational/advertising or demand shift impact of coupons, as opposed to the price impact which could not be determined since data on prices were a weighted average for coupon users and non-users. The results indicate a 6% increase in OJ gallons sales when coupons are used. The coupon variable used in the analysis, however, measures the extent of coupon usage but not intensity. As such, the results provide a partial view of the impact of coupons and further analysis on data that also includes some measure of intensity is needed to more fully evaluate... |

| This study examines imposing and testing restrictions on preference variables in the Rotterdam model through the impacts of these variables on marginal utilities. An empirical analysis of the impact of a female labor force participation variable in a Rotterdam demand system for fresh fruit illustrates the methodology. This variable was modeled through its impact on marginal utilities via "adjusted" prices, following theoretical work by Basmann and Barten, among others. Results show that the female labor participation has negatively impacted the demands for citrus, while positively impacting the demands for other fresh fruit. |

| 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... |

| The quantity demanded in a market can be decomposed into two components: the number of purchasers and the quantity per purchaser. Focusing on these two components, the demands for different types of single-flavor fruit juice commodities are analyzed. The approach allows the market demand elasticities to be estimated as the sum of elasticity estimates for the numbers of purchasers and the elasticity estimates for the quantities per purchaser. The method of seemingly unrelated regressions is employed to estimate the equations for the two demand components for the different types of juice. |
