Question

Describe in detail characteristics of ‘Cournot’s model’.

Answer 1

Cournot’s model, one of the foundational theories in oligopoly economics, is based on how firms compete by choosing output quantities. Below are the detailed characteristics drawn from both textual and visual content you’ve shared:

1. Simultaneous Output Decisions: Firms decide how much to produce at the same time, without knowing how much their competitors will produce.
2. Quantity Competition: Instead of competing on price, firms compete by deciding how much to produce, unlike in the Bertrand model, which focuses on price competition.
3. Constant Output Assumption: Each firm believes its competitor will keep its output unchanged, and based on that, it adjusts its own output to gain maximum profit.
4. Homogeneous Product: The product offered by all firms is uniform and lacks differentiation.
5. Fixed Number of Firms: The model assumes that the number of firms in the market is fixed and does not change.
6. Market Power: A firm’s decision on how much to produce affects the total supply in the market, which in turn impacts the price, giving the firm some control over pricing.
7. Nash Equilibrium: The equilibrium in Cournot’s model is a Nash equilibrium, where each firm chooses the optimal output level considering the output of other firms.
8. Strategic Interdependence: The outcome of one firm’s decision depends on what the other firm does, making their decisions strategically linked.
9. Non-cooperative: Firms act individually and do not engage in agreements or coordination regarding their production levels.
