Game theory: cournot, bertrand + stackelberg Cournot Oligopoly by Jerrod McFarland Oligopoly (Collusion, contestable markets, Cournot, Stackelberg and Bertrand) By Jerrod McFarland An oligopoly is a market structure in which there are only a few firms, each of which is large relative to the total industry

Note: the Stackelberg oligopoly Bertrand is a model that competes on price while Cournot is model that competes on quantities (sales volume)

The Bertrand duopoly model examines price competition among firms that produce differentiated but highly substitutable products

ThestaticCournot- Cournot-konkurrence opfattes ofte fejlagtigt som studiet af konkurrence i et duopol det vil sige hvor der kun er to Stackelberg-konkurrence; Bertrand-konkurrence; Stackelberg leadership is understood as a stationary supply taking account of the follower's Cournot reaction function

Stackelberg: compete on quantity in a sequential I am looking for a real world example of an industry or company that fits each of the oligopoly models (Bertrand, Stackelberg, and Cournot)

The Cournot model of oligopoly assumes that rival firms produce a homogenous product, and each attempts to maximize profits by choosing how much to produce

Example: comparing market structures The basics: Differences between Cournot and Stackelberg: In Cournot, firm 1 chooses its quantity given the quantity of firm 2 In Stackelberg, Chapter 13a - Oligopoly Goals: 1

Which model (Cournot, Bertrand) To compare Cournot and Stackelberg equilibrium it is useful to define and find the Best response Why is the price higher in a Cournot equilibrium than in a When Do First-Movers Have an Advantage? A Stackelberg Classroom positive profits in equilibrium for both Cournot and Bertrand games

However, given the follower always adheres to the reaction function, the leader could also choose a dynamic, for instance, periodic sales policy over time

In a Stackelberg Cournot game, one firm (called Firm 1) moves first and chooses a quantity to produce

Entry 3: In oligopoly there are four different types known as Sweezy oligopoly, Cournot oligopoly, Stackelberg and Bertrand oligopoly generates zero economic profit and Cournot competition is an economic model used to describe industry Bertrand versus Cournot

the players are the firms the actions of each firm are the set of possible outputs (any nonnegative amount) Figure 1: Plot of the Cournot-Bertrand profit differential for application firms (), social welfare differential (), and in the parametric plane

The Stackelberg and Cournot models are similar because in COURNOT COMPETITION C000591 Cournot’s 1838 model of strategic interaction between competing firms has become the primary workhorse for the analysis of imperfect Cournot’s model of oligopoly Bertrand’s model of oligopoly Equilibria in Cournot’s and Bertrand’s models generate In many industries, firms pre-order input and forward sell output prior to the actual production period
