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...

A demand model is developed to examine the impacts on orange juice prices resulting from elimination or reduction of the tariffs on orange juice imposed by the United States, European Union, and Japan. An empirical analysis suggests that elimination of the U.S. tariff by itself would decrease...

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...

This study adopted the scaling approach to examine the impacts of inventories on tuna auction prices in Japan using the Rotterdam inverse demand system. The inclusion of two inventory variables in the model only increases the number of parameters by two. Results indicate that frozen tunas are...

Nielsen ScanTrack data were used to study how income and prices influenced consumer juice beverage demand in the United States during the period from 1988-89 through 1991-92. Alternative differential demand models combining the features of the Rotterdam model and the almost ideal demand system...

This study examined the impacts of four promotional tactics—features, displays, features and display together, and temporary price reductions—in context of a conditional demand system for 12 beverages. The Rotterdam model with promotion effects specified through the...

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...
