The almost ideal demand system (AIDS) is commonly used to study demand for agricultural commodities and groups of commodities. Increasingly, separability has been utilized in conjunction with the AIDS to estimate conditional demand systems as well as to improve upon precision of parameter...

The study examined the relationship between import price and retail price of grapefruit in Japan. Estimated retail-import price relationship indicate asymmetry responses distributed over time. Import price changes are not fully transmitted to the retail level, with import price increases being...

A model is developed to explain Florida citrus planting levels by variety. The varietal choice is based on the expected prices and price variances/covariances of the varieties under consideration. Overall planting returns are maximized for a given level of price risk. The model's price...

A demand system model differentiating goods by product form and origin is developed to examine the impact of eliminating U.S. tariffs on orange-juice prices. An empirical analysis suggests a range of tariff impacts on prices depending on the degree of substitution between products. The model...

Increased demand for an advertised product may increase price, which, in turn, may lead to a free rider problem where competitive imports increase and result in a smaller price increase than otherwise. A study of Florida Department of Citrus advertising for orange juice indicated that the free...

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...
