Bertrand competition is a model of competition used in economics, named after Joseph Louis François Bertrand (1822–1900). It describes interactions among firms (sellers) that set prices and their customers (buyers) that choose quantities at the prices set.
Solutions to the Paradox attempt to derive solutions that are more in line with solutions from the Cournot model of competition, where two firms in a market earn positive profits that lie somewhere between the perfectly competitive and monopoly levels. Some reasons the Bertrand paradox do not strictly apply: Capacity constraints. Sometimes ...
As a solution to the Bertrand paradox in economics, it has been suggested that each firm produces a somewhat differentiated product, and consequently faces a demand curve that is downward-sloping for all levels of the firm's price.
In microeconomics, the Bertrand–Edgeworth model of price-setting oligopoly looks at what happens when there is a homogeneous product (i.e. consumers want to buy from the cheapest seller) where there is a limit to the output of firms which are willing and able to sell at a particular price. This differs from the Bertrand competition model ...
A veridical paradox is a paradox whose correct solution seems to be counterintuitive. It may seem intuitive that the probability that the remaining coin is gold should be 1 / 2 , but the probability is actually 2 / 3 . [1] Bertrand showed that if 1 / 2 were correct, it would result in a contradiction, so 1 / 2 ...
The Edgeworth model shows that the oligopoly price fluctuates between the perfect competition market and the perfect monopoly, and there is no stable equilibrium. [6] Unlike the Bertrand paradox, the situation of both companies charging zero-profit prices is not an equilibrium, since either company can raise its price and generate profits.
Bertrand model concludes that each firm will set P=MC. (So each firm's profit is zero just as in perfect competition.) But if FC > 0, then AC > MC. In this case P=MC will induce to a negative profit since a zero profit is attained at P=AC. So in Bertrand model with FC > 0, each firm should set P=AC, not P=MC.
The Bertrand paradox is a problem within the classical interpretation of probability theory. Joseph Bertrand introduced it in his work Calcul des probabilités (1889) [1] as an example to show that the principle of indifference may not produce definite, well-defined results for probabilities if it is applied uncritically when the domain of possibilities is infinite.
