A wealth accumulation model

[eng] Insight into the mechanisms involved in the wealth accumulation process of the various economic agents remains generally partial. Thus, from a didactical point of view, it appears useful to describe, in twenty simple relations, the main stages of this process, by linking as closely as possible « real » variables to financial ones. In the first place, it appears thus necessary to establish equilibrium relations between flows of financial resources and their uses distinguishing national economies’ sectors from the « rest of the world ». In the second place, while keeping with the same distinction, wealth accumulation relations are developed. While remaining very close to the European System of Accounts, it was sometimes deemed useful to shed some light on relations that are considered as useful for a good understanding of the issues at stake. .
