The Bertrand and Cournot models are two different approaches to analyzing oligopoly behavior. They both focus on firms' strategic interactions in setting prices or quantities, but they make different assumptions about firms' decision-making processes and market outcomes.
1. Bertrand Model:
In the Bertrand model, firms compete by setting prices rather than quantities. It assumes that firms have the ability to adjust their prices quickly in response to market conditions. The key assumption is that firms have perfect information about their competitors' prices and costs. This model predicts that firms will engage in price competition, leading to a situation where prices are driven down to marginal cost and profits are zero.
Example: The airline industry is often considered an example of the Bertrand model. Airlines compete by setting ticket prices, and customers tend to choose the airline with the lowest price. As a result, airlines engage in intense price competition, often leading to low-profit margins.
2. Cournot Model:
In the Cournot model, firms compete by choosing quantities of output rather than prices. It assumes that firms make their production decisions simultaneously and independently, without perfect information about their competitors' quantities. The key assumption is that firms take into account their rivals' quantities when determining their own level of output. This model predicts that firms will choose quantities that maximize their profits, taking into account the expected reaction of their competitors.
Example: The oil industry can be seen as an example of the Cournot model. Oil producers, such as OPEC members, determine their production levels based on their estimates of global demand and the expected production decisions of other producers. Each firm tries to maximize its profits by considering the market share it can capture with its output level.
In summary, the Bertrand model assumes price competition with perfect information, while the Cournot model assumes quantity competition with imperfect information. The Bertrand model predicts zero profits and price competition, while the Cournot model predicts positive profits and quantity competition.
