AIDS and separability: a non sequitur

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 estimates. The paper shows that separability conditions are inconsistent with use of the AIDS and that tests of separability with the AIDS are problematic.
