Qualitative and temporal aggregation

Behavioral assumptions, rational or otherwise, are not solid enough to be eligible as first principles of theoretical economics. Hence all endeavors to lay the formal foundation on a new site and at a deeper level actually need no further vindication. The present paper suggests three non-behavioral axioms as groundwork and applies them to the analysis of qualitative and temporal aggregation in the pure consumption economy. It turns out that the structural axiom set is self-similar with regard to the differentiation of the household- and business sector as well as to the sequencing of time.
