This paper develops a differential game model of a market of substitutable products. To avoid the problem of time-inconsistency, we solve a feedback Nash equilibrium solution for the game. A set of state-dependent equilibrium strategies is derived. Extensions of the model to a stochastic formulation and to an infinite time horizon specification are also provided.enA differential game model of a market of substitutable productsPeer Reviewed Journal Article10.1016/0377-2217(95)00083-6
