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.
The model also ignores capacity constraints. If a single firm does not have the capacity to supply the whole market then the "price equals marginal cost" result may not hold. The analysis of this case was started by Francis Ysidro Edgeworth and has become known as the Bertrand–Edgeworth model.
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 ...
An Edgeworth price cycle is cyclical pattern in prices characterized by an initial jump, which is then followed by a slower decline back towards the initial level. The term was introduced by Maskin and Tirole (1988) [ 1 ] in a theoretical setting featuring two firms bidding sequentially and where the winner captures the full market.
Bertrand–Edgeworth model A microeconomic model of price-setting oligopoly which studies 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 they are willing and able to sell at a particular price.
Edgeworth demonstrated that traders will ultimately reach a point on the contract curve (between C and C') through a stylized bargaining process which is termed the recontracting process. As neither person can be made better off without the other being made worse off at points on the contract curve, once the traders agree to settle at a point ...
