Abstract: | We show that the known uniqueness results for leader-follower Cournot games with multiple but identical leaders hinge on the tacit assumption that identical leaders make identical decisions. We illustrate that without this assumption multi-leader Cournot games may well possess nontrivial manifolds of equilibria and discuss the underlying reasons. |
