## What is different about the two models the Cournot and Bertrand models are different in that?

What is different about the two models? firms earn positive economic profits under the Cournot model but earn zero profits under the Bertrand model.

## What is Cournot model and the assumptions behind it?

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. All firms choose output (quantity) simultaneously. The basic Cournot assumption is that each firm chooses its quantity, taking as given the quantity of its rivals.

**Why did Bertrand criticized the Cournot model?**

Bertrand criticized Cournot’s analysis of the competitive process, arguing that firms should be seen as playing a strategy of setting price below competitors’ prices (henceforth, the Bertrand strategy) instead of a strategy of accepting the price needed to sell an optimal quantity (the Cournot strategy).

**What are the similarities and differences between the Cournot model and the Bertrand model?**

In the Cournot model, firms control their production level, which influences the market price, while in the Bertrand model, firms choose the price of a unit of product to affect the market demand.

### What is the difference between Cournot and Stackelberg?

In a Cournot duopoly, firms make their moves at the same time while in Stackelberg duopoly, one firm becomes the leader and so make the first move, followed by the other firm. The profit gained by each firm when both are competing in a Cournot duopoly and Stackelberg duopoly model were derived and compared.

### Is Cournot model efficient?

Comparison with competitive equilibrium We conclude that the firms’ outputs and the price are different in a Nash equilibrium than they are in a competitive equilibrium. An implication is that, as for a monopoly, the Nash equilibrium outcome in a Cournot duopoly is not Pareto efficient.

**Why is Cournot equilibrium suboptimal?**

The question arises of why the firms choose the suboptimal equilibrium e. The answer is that the Cournot pattern of behaviour implies that the firms do not learn from past experience, each expecting the other to remain at a given position.

**Is Cournot or Bertrand more efficient?**

Bertrand competition is generally viewed as more efficient in welfare terms than Cournot competition. Moreover, individual firms’ ex ante expected profits as well as their actually realised profits are often higher in the Bertrand game.

#### How is the Cournot model different from the Bertrand model?

The Cournot model considers firms that make an identical product and make output decisions simultaneously. The Bertrand model considers firms that make and identical product but compete on price and make their pricing decisions simultaneously.

#### Why is the iterated version of the Prisoner’s dilemma important?

The iterated prisoner’s dilemma game is fundamental to some theories of human cooperation and trust. On the assumption that the game can model transactions between two people requiring trust, cooperative behaviour in populations may be modeled by a multi-player, iterated, version of the game.

**Which is the best description of Cournot competition?**

Cournot Competition describes an industry structure (i.e. an oligopoly) in which competing companies simultaneously (and independently) chose a quantity to produce. The total quantity supplied by all firms then determines the market price.

**Why is the Prisoner’s Dilemma An example of game theory?**

The prisoner’s dilemma is a standard example of a game analyzed in game theory that shows why two completely rational individuals might not cooperate, even if it appears that it is in their best interests to do so.
