Résumé
This paper first aims at tackling the redistributional aspect of public pricing in association with its spatial dimension. Feldstein's model, which allows the implementation of optimal redistributional pricing, is modified in two of its features. On the one hand, one has to create a model which will be able to account for a spatial redistribution, in terms which will be likely to initiate a differentiated pricing according to the agents' localization. On the other hand, the hypothesis of a log-normal distribution of the agents' incomes is abandoned and replaced by the three parameter Camillo Dagum's Model I distribution which is better adapted to the lowest and highest levels of income distribution.
