Baseline estimates are generated using the Box-Jenkins time series expectation of non-promoted volume calculated at the store/week/UPC level. The expectation of sales is a weighted moving average of weekly observations of normal non-promoted volume. The relationship between baseline volume and...

This report provides fresh grapefruit import data regarding European Union 15 (EU-15) and an in-depth look into the share changes for fresh grapefruit imports by country of origin during the period from 1989 through 2006. The Rotterdam demand system was used to study the relationship among 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.

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...

This study uses the household production theory to study the demand for nutrients, i.e., households purchase a combination of food items from the market and produce the needed nutrients from these food items. By following the traditional household production approach, shadow prices for nutrients...
