| Abstract: | In a general setting, the envelope theorem and fundamental comparative statics curvature theorems for the Stackelberg leader and follower are proven in a simple and direct fashion using a dual method. The comparative statics theorems are unconventional from a primal point of view, which explains why they are heretofore undiscovered. The theorems are applied to a classical model of entry deterrence so as to elucidate their economic interpretation. The difference btw. the qualitative comparative statics properties of the leader and follower allows, in principle, an empirical test of the leader-follower role. |
