Answer:
Stackelberg duopoly
Explanation:
The Stackelberg duopoly is characterized by having two firms that produce a homogeneous good, both face the same costs and the same demand. One of the two firms is the leader and the other is the follower. This happens because one of them is bigger or is more recognized. The leader firm can choose the quantity that it will produce (q1) and then the follower firm will produce according to the leader firm choice. In game theory, people use backward induction to find the Nash equilibrium.
