We show that the famous neutrality result in the theory of public good contributions (Warr, Kemp, Bergstrom, Blume and Varian) depends crucially on the assumption that agents do not take into account the effect of their public good contribution decisions on the relative price of the private goods. Thus, the scope of applicability of their result is not as large as one might at first think. Our non-neutrality results hold even if all countries are identical in technology, preferences, and endowments.
Nous démontrons que le théorème sur l’invariance du stock total d’un bien public par rapport à la distribution de revenus n’est valable que si les contributeurs ignorent l’impact de leurs contributions sur le prix relatif des biens privés. Par conséquent, le résultat de Warr, Kemp, Bergstrom, Blume et Varian n’a qu’une sphère d’application limitée. Nos résultats sur le manque de neutralité sont valables même si les préférences, les technologies, et les dotations de ressources de tous les pays sont identiques.
