Abstract

We investigate a Stackelberg oligopoly model in which m leaders and N-m followers compete. We find an asymmetric welfare implication of the Stackelberg model. Introducing a small number of leaders into the Cournot model can reduce welfare. However, introducing a small number of followers into the Cournot model always improves welfare. The key result behind this asymmetry is contrasting limit results in the cases where m → 0 and m → N. We also discuss the optimal number of leaders and the integer constraint for the number of the firms.
