Abstract

In this paper we will study and classify the main types of goods, from the perspective of a global analysis (for n goods simultaneous). For each of the main types, we will present one concrete example resulting from special utility functions. Also we will broach the Engel’s  hypersurfaces which generalize the Engel’s curves from the case of two goods. The problem of elasticity is also broach in order to settle essential links (for n goods) between their level and nature of the goods.
