A Coalitional Differential Game of Vaccine Producers

The paper proposes a game-theoretic model of competition and cooperation, including partial cooperation, of vaccine producers. Various versions of players’ cooperation (partial and full) have been studied. The differential game has an infinite duration. For each possible coalition of players, the profits and production quantities of its members are determined. An stability analysis of possible coalition structures, as well as coalitions that are most attractive to customers has been made.
