The Stackelberg model explains how being the first mover in a market gives a firm a competitive edge. The first-mover advantage is the benefit of increased brand recognition, customer loyalty, and increased sales that often accompany a business who is the very first to enter the marketplace with a new product. The leader firm decides on its production first, anticipating that the follower will adjust its output accordingly. This allows the leader to influence market conditions and secure higher profits, which depend on factors such as cost structures, demand elasticity, and the follower’s response. Firms with lower production costs can maintain higher margins, while highly elastic demand makes small price changes impactful. Additionally, the follower’s strategy—whether to compete aggressively or take a passive approach—determines the leader’s long-term advantage.

Imagine two companies, BrightEnergy and EcoPower, both producing wind turbines. BrightEnergy, as the leader, strategically sets its production level at 15,000 turbines to maximize profit given the expected follower response. EcoPower, observing this, determines its best response and produces 10,000 turbines.

The relationship between the two firms is reflected in their reaction functions, which indicate how the follower responds to the leader’s decision. In a Stackelberg model, equilibrium is achieved when the leader firm, which moves first, chooses an output level that maximizes its profit. BrightEnergy’s higher output alters EcoPower’s profit-maximizing choice.

This model illustrates the advantage of moving first in decision-making. By committing to a production level first, the leader influences the strategic choices of the follower, shaping its response. The leader’s advantage depends on how the follower reacts—some followers may limit output, while others might attempt to compete more aggressively. This dynamic allows the leader to strengthen its position, though it does not always prevent competitive responses. 

Firms that anticipate market reactions and act strategically can sustain a competitive edge while maintaining market stability.
