Abstract

L'article propose une théorie de la compétition électorale ambigüe. Une plate-forme est ambigüe si les votants peuvent l'interpréter de différentes manières. Une telle plate-forme met plus ou moins de poids sur sur les différentes options possibles de sorte qu'elle est plus ou moins facilement interprétée comme une politique ou une autre. On fait l'hypothèse que les partis politiques peuvent contrôler exactement leurs plate-formes mais ne peuvent pas cibler celles-ci vers les votants individuellement. Chaque électeur vote d'après son interprétation des plate-formes des partis mais est averse à l'ambiguité. On montre que ce jeu de compétition électorale n'a pas d'équilibre de Nash. Cependant ses stratégies max-min sont les stratégies optimales du jeu Downsien en stratégies mixtes. De plus, si les partis se comportent de manière suffisament prudente par rapport à l'aversion pour l'ambiguité des électeurs, ces mêmes stratégies forment un équilibre.
