Strong Time-Consistency in the Cartel-versus-Fringe Model

In the seventies and eighties, the theory of exhaustible natural resources developed a branch, which was called the cartel-versus-fringe model, to characterize markets with one large coherent cartel and a big number of small suppliers named the fringe.It was considered appropriate to use the von Stackelberg solution concept but because solutions could only be derived in an open-loop framework time-inconsistency resulted.This paper solves time-inconsistency in the cartel-versus-fringe model and provides the feedback von Stackelberg equilibrium for all cost configurations.
