Résumé

Nous proposons de fonder la dispersion des prix sur l'écart entre les horizons passés (les «expériences») des différentes générations de clients. L'argument de base est simple : la vieille génération dotée d'une certaine connaissance du marché sera naturellement plus exigeante que les jeunes qui ne savent rien encore. Nous nous plaçons dans un modèle à générations imbriquées. Supposant d'abord la population constante, nous caractérisons l'équilibre de marché. Puis, supposant la population variable, nous apprécions l'influence de son taux de croissance sur la distribution des prix.

Summary

Summary

First, we propose to base the price dispersion upon the deviation between the experiments of several clients generations. The principle is such that we assume the old generation to endow a market knowledge and thus, to be more demanding than the young one who does not possess any knowledge. Second, we define our framework inside of an overlapped generations model. Hence, assuming both populations to be constant, the associated market equilibrium is characterised. Third, and last, assuming both populations to be variable, we evaluate the influence of their growth rate on the price distribution.
