Stackelberg Competition
Stackelberg Oligopoly Model with Leader-Follower Dynamics · Also known as: Quantity Leadership, Sequential Oligopoly, Stackelberg Equilibrium
Stackelberg Competition models sequential oligopolistic markets where one firm (the leader) commits to a quantity first, and other firms (followers) observe this choice and respond. Introduced by Heinrich von Stackelberg in 1934, the model captures first-mover advantage in quantity-setting competition. The resulting Stackelberg Equilibrium, found by backward induction, yields the leader higher profit than simultaneous (Cournot) competition.

When to use it
Apply Stackelberg analysis when one firm moves first with a credible commitment (e.g., capacity investment, market entry timing). Use when modeling industries where first-movers gain strategic advantage or when firms have heterogeneous information about demand or costs. Stackelberg is appropriate when sequential moves are realistic (e.g., established firm versus entrant).
Strengths & limitations
- First-mover advantage: leader earns higher profit than in simultaneous competition
- Subgame perfection: equilibrium is resistant to deviation at any decision node
- Realism for sequential markets: captures real-world situations where timing of entry or commitment matters
- Tractable analysis: backward induction yields closed-form equilibrium for many structures
- Assumes commitment credibility: leader cannot revise quantity; relaxing this reduces advantage
- Follower's response may not be optimal if leader quantity is outside follower's feasible range
- Multiple followers complicate analysis; equilibrium may be less pronounced
- Static model: does not capture dynamic adjustments or repeated interaction over time
Frequently asked
What is the source of the leader's advantage in Stackelberg competition?
The leader can commit to a high quantity, forcing the follower (who maximizes given the leader's choice) to produce less. This reduces total market output and raises prices, benefiting the leader. The follower's optimal response to high leader quantity is to produce less.
Can the follower ever earn higher profit than the leader?
No. By definition, the leader moves first and chooses the quantity that maximizes its own profit anticipating the follower's response. The follower, constrained by the leader's choice, earns lower profit than the leader in equilibrium.
How does Stackelberg equilibrium compare to Cournot equilibrium?
The leader produces more quantity in Stackelberg than in Cournot, the follower produces less, and total quantity is higher in Stackelberg than Cournot. Prices are lower in Stackelberg, but the leader's profit is higher due to the quantity advantage.
