Past parametric tests of demand system rank employed polynomial Engel curve systems. However, by Gorman's (1981 …) theorem, the maximum possible rank of a utility derived polynomial demand system is three. The present paper proposes a class … of demand systems that are utility derived, are close to polynomial, and have rank four. These systems nest rational …
