Abstract: There have been doubts if the common demand systems as LES or even AIDS were flexibel enough to estimate Engel curves. It is shown that the propositions to introduce three or even more parameters into the estimation, can be justified by economic theory. A Lancaster model with an utility function that allows for subsistence levels and satiation barriers, can generate Engel curves which cannot be estimated adequately by the common approaches.
