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.

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...

A mixed demand system is developed using the fundamental matrix equation of demand theory. The model parameterization combines the parameterizations of the quantity- and price- dependent Rotterdam models. The relationship between the mixed-demand-model parameters and the underlying direct and...

The differential demand model for uniform substitutes is used to analyze demand for orange-juice products. Consumption trends are examined by allowing the marginal propensities to consume to vary with time. Results indicate ready-to-serve (frozen concentrated) orange juice has become more (less)...

Asymmetry is introduced into the Rotterdam model by allowing the income response to depend on whether real income increases or decreases. Price responses, in turn, are asymmetric through the general and specific substitution terms. Analysis of data on food and three other broadly defined goods...

The paper focuses on separability in the almost ideal demand system (AIDS) in time series analysis. The AIDS approximation based on Stone's price index is specified in terms of the Rotterdam model and block additivity is imposed for illustrative purposes. A generalization to other types of...

Alternative theoretically based restrictions on autoregressive error processes in systems of demand equations are examined. Scaling, translation, and a utility-based approach suggested by Theil are used to generate restrictions. A study of juice demands suggests that the restrictions examined...
