Furthermore, each good with a downward-sloping demand curve must have at least one gross substitute and each Giffen good - if there are any - must have at least one gross complement.

For example, Boland makes a lengthy argument that neoclassical economics cannot admit the possibility of a Giffen good
because such goods are inconsistent with the well-known stability conditions for market-determined prices; if the demand curve slopes upward, there may be no determinate market price.
Dougan |1982~ quite convincingly points out that little evidence would come from an analysis of market demand curves, Johnston and Larson suggest, however, that a substantial body of econometric evidence on Giffen goods exists in the agricultural economics literature.
The question of interest is how to define a Giffen good. In the original sense of Hicksian utility analysis, potential Giffen goods are generated by very unusual preferences.
The original purpose of our paper was to attempt to answer Boland's criticism of utility theory--namely that if we cannot dismiss the existence of Giffen goods we should at least be able to predict the conditions that generate them.
(1.) As pointed out by referee, Marshall's original reference to Giffen goods concerned bread and meat.
also recognizes the critical element of subsistence in his presentation of Giffen goods. In his analysis, however, the Giffen effect is generated in the conventional fashion by relying on the shape of the indiference curves.
dealt with the Giffen good by dismissing it as a theoretical possibility but a practical impossibility.
