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 ...
Edgeworth's model follows Bertrand's hypothesis, where each seller assumes that the price of its competitor, not its output, remains constant. Suppose there are two sellers, A and B, facing the same demand curve in the market. To explain Edgeworth's model, let us first assume that A is the only seller in the market.
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 ...
The Cournot model and Bertrand model are the most well-known models in oligopoly theory, and have been studied and reviewed by numerous economists. [54] The Cournot-Bertrand model is a hybrid of these two models and was first developed by Bylka and Komar in 1976. [55] This model allows the market to be split into two groups of firms.
In his review, Bertrand argued that each firm should instead maximise its profits by selecting a price level that undercuts its competitors' prices, when their prices exceed marginal cost. [2] The model was not formalized by Bertrand; however, the idea was developed into a mathematical model by Francis Ysidro Edgeworth in 1889. [3]
Edgeworth criticised the marginal productivity theory in several articles (1904, 1911), and tried to refine the neo-classical theory of distribution on a more solid basis. Although his work in questions of war finance during World War I was original, they were a bit too theoretical and did not achieve the practical influence he had hoped.
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.
