Abstract

This experiment evaluates various systems of taxation on the number of real tasks performed by participants and in terms of fiscal income generated to help government in its redistributive goal. The first treatment concerns a proportional system of taxation. The second treatment considers an equivalent progressive income tax system. Finally, participants are submitted sequentially to different flat tax rates. This last treatment evaluates the reaction of participants to fiscal changes. Our results support clearly that a progressive taxation system reduces work effort relative to a single flat tax. The single flat tax system yields more fiscal income. The results also show that individuals are affected by their own tax system and by the other forms of taxation they experienced before L'enjeu de cet article est de savoir si l'incidence fiscale sur l'offre de travail et sur les rentrées fiscales est identique selon le système d'imposition en vigueur. Ainsi, un système progressif décourage-t-il davantage l'offre de travail qu'un système proportionnel ? Quel système de taxation permet à l'état de remplir au mieux son rôle redistributif ? Afin de répondre à ces questions, l'approche mobilisée est l'économie expérimentale. Trois traitements ont été réalisés. Dans un premier traitement, les participants doivent réaliser un effort réel sous un système d'imposition proportionnel. Dans un second traitement, le système d'imposition en vigueur est un système progressif équivalent. Enfin dans un troisième traitement, les participants sont confrontés successivement à plusieurs systèmes d'imposition. Ce dernier traitement permet d'étudier l'incidence de changement de système sur les décisions individuelles. Nos résultats expérimentaux montrent que les effets désincitatifs sur l'offre de travail sont plus importants sous un système progressif que sous un système proportionnel sans contexte. De plus le systèms proportionnel sans contexte permet des rentrées fiscales plus importantes.
