Mr. Caputo, A DUAL VISTA OF THE STACKELBERG DUOPOLY REVEALS ITS FUNDAMENTAL QUALITATIVE STRUCTURE, International journal of industrial organization, 16(3), 1998, pp. 333-352
In a general setting, the envelope theorem and fundamental comparative
statics; curvature theorems for the Stackelberg leader and follower a
re proven in a simple and direct fashion using a dual method. The comp
arative statics theorems are unconventional from a primal point of vie
w, which explains why they are heretofore undiscovered. The theorems a
re applied to a classical model of entry deterrence so as to elucidate
their economic interpretation. The difference between the qualitative
comparative statics properties of the leader and follower allows, in
principle, an empirical test of the leader-follower role. (C) 1998 Els
