Recall that in the Stackelberg model, the firm that moved first gained an advantage by committing itself to a large output. Making a commitment constraining its future behavior is crucial. To see why, suppose that the first mover (Firm1) could later change its mind in response to why Firm 2 does. What could happen? Clearly, Firm 2 would produce a large output. Why? Because it kwons that Firm 1 will respond by reducing the output that it first announced. The only why that Firm 1 can gain a first-mover advantage is by committing itself. In effect, Firm 1 constrains Firm 2’s behavior by constraining its own behavior.ket altogether?
