Therefore, the sole equilibrium in the Bertrand model emerges when both firms establish a price equal to unit cost, known as the competitive price. [9] It is to highlight that the Bertrand equilibrium is a weak Nash-equilibrium. The firms lose nothing by deviating from the competitive price: it is an equilibrium simply because each firm can ...
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.
Some reasons the Bertrand paradox do not strictly apply: Capacity constraints. Sometimes firms do not have enough capacity to satisfy all demand. This was a point first raised by Francis Edgeworth [5] and gave rise to the Bertrand–Edgeworth model. Integer pricing. Prices higher than MC are ruled out because one firm can undercut another by an ...
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 ...

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 ...
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.
Its domain is the power set of (with the empty set removed), and so makes sense for any set , whereas with the definition used elsewhere in this article, the domain of a choice function on a collection of sets is that collection, and so only makes sense for sets of sets. With this alternate notion of choice function, the axiom of choice can be ...
