Abstract: This paper focuses on the existence of a Cournot equilibrium in a n- firm Cournot market for a single homogeneous commodity. Using a simple argument and proof, it shows that a Cournot equilibrium exists if each firm's marginal revenue declines with its own output and some weak non-decreasing incremental cost condition is satisfied.
