Information et différenciation du produit sur un marché de duopole

Abstract

This paper focuses on the role of the information in the following decision problem: two duopolists choose to diversify or not their product line by issuing a new good. Using the tools of the non cooperative game theory, we examine successively a simultaneous game and a sequential one. In each game the case of the complete information is first resolved: then the analysis is developed in an incomplete information context. The results are finally extended to a competitive model à la Hotelling.
