Game theory is the study of mathematical models of ... The production costs are public information and the firm aims to find their profit-maximizing quantity based on ...
Reactions to this aspect of Cournot's theory have ranged from searing condemnation to half-hearted endorsement. It has received sympathy in recent years as a contribution to game theory rather than economics. James W. Friedman explains: In current language and interpretation, Cournot postulated a particular game to represent an oligopolistic ...
In these alternative models of oligopoly, a small number of firms earn positive profits by charging prices above cost. Suppose two firms, A and B, sell a homogeneous commodity, each with the same cost of production and distribution, so that customers choose the product solely on the basis of price. It follows that demand is infinitely price ...
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.
Experimental and game-theory methods have been developed to model and test theories of information economics, [9] including potential public-policy applications such as mechanism design to elicit information-sharing and otherwise welfare-enhancing behavior.
A Stackelberg game represented in extensive form. The image on the left depicts in extensive form a Stackelberg game. The payoffs are shown on the right. This example is fairly simple. There is a basic cost structure involving only marginal cost (there is no fixed cost). The demand function is linear and price elasticity of demand is 1.
With perfect information in a market, all consumers and producers have complete and instantaneous knowledge of all market prices, their own utility, and own cost functions. In game theory, a sequential game has perfect information if each player, when making any decision, is perfectly informed of all the events that have previously occurred ...
The empirical fact that subjects in most societies contribute anything in the simple public goods game is a challenge for game theory to explain via a motive of total self-interest, although it can do better with the "punishment" variant or the "iterated" variant; because some of the motivation to contribute is now purely "rational" if players ...
