Demand relationships for two closely related products -- grapefruit juice and grapefruit-juice cocktail -- were estimated from grocery-store scanner data to analyze the contention that consumer confusion exists between the two products. Results suggest confusion may exist, with grapefruit-juice...

Seven systems of Engel curves for expenditures on ten commodity groups were estimated using Taiwanese household expenditure data for the period from 1996 through 1998. Results show that the estimated expenditure elasticities are insensitive to the choice of functional forms.

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...

The system-wide approach is used to develop an import allocation model based on blockwise dependence. The import demand system is parameterized using the absolute version of the Rotterdam model. Two empirical examples are given to illustrate the approach.

In this study, the impacts of Florida Department of Citrus (FDOC) orange juice (OJ) advertising on U.S., OJ demand and the price received by Florida growers are examined.

As the U.S. domestic demand for fresh grapefruit and grapefruit juice trends downward, the export markets become more and more important for the citrus industry. Prior research suggests that when studying export demand relationships, exchange rates play an important role. The purpose of this...

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...

Tropicana introduced a new package design as part of its advertising and branding campaign, with the theme “Squeeze it’s a Natural in January 2009. Sales of the Tropicana Pure Premium line plummeted 20% between the January and February from the same period a year ago. Tropicana had changed...

The cross-section and time series model used in this study yielded a number of important estimates for OJ and GJ demand. The own- and cross-price elasticities were, in general, similar to those found in past studies. The dummy variable estimates to control for city size, seasonality and other...

In this study, city-by-city, weekly grocery store sales data were used to estimate the impacts of the FDOC, TV, RADIO and HC promotional programs. The estimates indicate that the RADIO program was effective, having a B/C of 1.4. For the TV and HC programs, benefits were less than costs.
