What is Stackelberg competition in simple terms?

One firm decides how much to produce first, and the other sees that and then picks its own output. The first mover anticipates the rival's response and grabs the better position.

Is moving first always an advantage?

No. The commitment to an irreversible decision has to be credible, and when rivals tend to match your moves, as in price competition, moving second can be better.

Stackelberg Competition

📈 Economics By CampusDown Wiki Editorial Team Last updated October 27, 2026

Stackelberg competition is an oligopoly model introduced by the German economist Heinrich von Stackelberg in his 1934 book Market Structure and Equilibrium. A leader firm sets its output first, and a follower observes it before choosing its own. By anticipating the follower's response and producing more, the leader earns a larger profit than it would under simultaneous Cournot competition.

Structure and the first-mover advantage

Stackelberg (1934) dropped the assumption in Cournot's (1838) model that both firms decide at once and analyzed a setting in which one firm moves first. The follower picks its best response after seeing the leader's output, so the leader sets output with that reaction function in mind. The solution found by working backward this way, through backward induction, is a subgame perfect equilibrium as formalized by Selten (1965). With linear demand and equal costs, the leader produces more than the Cournot quantity and the follower less, so the leader's profit rises and the follower's falls. Total output is higher and price lower, which makes consumers better off than under Cournot.

Commitment, observability and entry deterrence

The leader's advantage exists only if its commitment to an output it cannot reverse is credible. As Schelling (1960) stressed, tying one's own hands can be a source of strategic power. Spence (1977) and Dixit (1980) developed this into models of entry deterrence, in which an incumbent invests in capacity in advance to keep out potential entrants. Bagwell (1995) showed that the first-mover advantage can vanish if the follower observes the leader's move only imperfectly. Gal-Or (1985) showed that with strategic complements, as in price competition, moving second can actually be better, and Hamilton and Slutsky (1990) proposed endogenous timing models in which firms choose who moves first.

Applications and experimental evidence

Brander and Spencer (1985) put forward the theory of strategic trade policy, in which a government uses export subsidies to effectively make a domestic firm a Stackelberg leader and shift profits away from foreign rivals. The argument heavily influenced debates over industrial policy and international competition. In experiments by Huck, Müller and Normann (2001), sequential markets produced more total output and greater efficiency than simultaneous ones, but followers responded as if punishing leaders' large outputs, so the first-mover advantage was smaller than theory predicts. Tirole (1988) established the model as a standard framework in oligopoly theory.
