Shared or Joint monopoly refers to anticompetitive behaviour by firms, normally an oligopoly, in order to secure monopoly profits for the firms as a group. Essentially, shared monopoly requires some form of collusion but stops short of being a formal cartel. It is therefore similar to tacit collusion. In a shared monopoly firms may not compete for the same customers and have instead local monopolies.
