We implement both a random matching and a ﬁxed-pairs version for each market.
- The Stackelberg leadership model is a strategic game in economics in which the leader firm moves first and then the follower firms move sequentially. It is named after the German economist Heinrich Freiherr von Stackelberg who published Market Structure and Equilibrium (Marktform und Gleichgewicht) in 1934 which described the model.
- From the consumer perspective, the Stackelberg competition is the best, with a total annual capacity of $562.5$ being sold at a price of $237.5$, followed by the Cournot competition with total annual capacity $500$ and price $300$, and unsurprisingly the monopoly is worst with total annual capacity $375$ and price $425$.
- The Stackelberg leader’s profits are always (weakly) higher with a positive complexity fixed cost, but its profits can be non-monotonic in the magnitude of this cost. The Stackelberg follower’s profits can be lower when the complexity fixed cost is positive than when it is equal to 0.

We model the suppliers’ operations as M/M/1 queues and demand as a linear function of the retail prices and promised delivery lead-times offered to the customers.
- We provide a general analysis of duopoly game in endogenous timing. The Nash equilibrium outcomes are compared with Stackelberg equilibrium outcomes. The different sets of conditions are provided for yielding respectively simultaneous and sequential plays and these conditions only depend on the monotonicities of the reaction functions and the payoffs functions in rival strategic variables.
- Oct 29, 2007 · It is shown that in our quantity-setting model Stackelberg-type outcomes can occur. In these outcomes the Stackelberg leader is owner-managed and the follower delegates the quantity choice to a manager, who is compensated based on profits and sales. Furthermore, the follower has a second-mover advantage, i.e. achieves a higher profit than the ...
- This turned the standard duopoly model into what became universally known as the Stackelberg leader–follower model. 9 That a firm took into account its rival's reaction was in fact the defining condition for it being a leader or, as Stackelberg called it in 1934, a firm in an independent position. A follower or, in Stackelberg's terminology ...
- Such fixed costs create an interdependency between firms' choices of quality tiers across different product lines, even when demands are independent. We investigate the effects of this interdependency on equilibrium profits in a Stackelberg duopoly game. Both firms' profits are (weakly) higher when the complexity cost is infinite than when it is 0.

competition as the advantage in Stackelberg markets is held by the follower8. For example, in a homogenous duopolistic market where symmetric firms are competing in prices using sequential timing, the follower has the advantage because using perfect information to undercut the leader’s price leads to the follower receiving higher demand. Stackelberg Duopoly has two firms controlling a large share of the market, and they compete by one firm first setting its output (or output capacity). Then, the other firm, then price is determined by demand.

It is assumed, by von Stackelberg, that one duopolist is sufficiently sophisticated to recognise that his competitor acts on the Cournot assumption. This recognition allows the sophisticated duopolist to determine the reaction curve of his rival and incorporate it in his own profit function, which he then proceeds to maximise like a monopolist. In the Stackelberg competition where firms set price sequentially, it is not rare for the second firm to have a better payoff if the demand functions are not symmetric. In your case firm 2 has lower total costs and therefore, it is likely it will have higher total profits.

A true duopoly is a specific type of oligopoly where only two producers exist in a market. There are two principle duopoly models: Cournot duopoly and Bertrand duopoly. Cournot Duopoly. Cournot duopoly is an economic model that describes an industry structure in which firms compete on output levels. The model makes the following assumptions:

Before a nonlinear duopoly model is presented, results based on static linear models will be briefly reminded . As was mentioned above, several different theoretical models about oligopoly exist, such as the Cournot duopoly game, Bertrand duopoly game or Stackelberg duopoly game. The inverse demand for a homogeneous-product stackelberg duopoly is p = 16,000 – 4q. the cost structures for the leader and the follower, respectively, are cl(ql) = 4,000ql and cf (qf) = 6,000qf.. a. what is the follower’s reaction function?

Jun 02, 2019 · Firms in a duopoly should be able to make high profits. It depends on the degree of barriers to entry. With two firms, there is a possibility of tacit collusion – or at least a quiet industry which avoids a price war. Over time, there is the possibility firms will learn from their behaviour and take a risk in keeping prices above marginal cost. competition as the advantage in Stackelberg markets is held by the follower8. For example, in a homogenous duopolistic market where symmetric firms are competing in prices using sequential timing, the follower has the advantage because using perfect information to undercut the leader’s price leads to the follower receiving higher demand.

Because the follower earns less profit than the leader, neither party will play the inferior role of the follower.
