Network Cournot Competition
Cournot competition, introduced in 1838 by Antoine Augustin Cournot, is a fundamental economic model that represents firms competing in a single market of a homogeneous good. Each firm tries to maximize its utility—naturally a function of the production cost as well as market price of the product—by deciding on the amount of production. This problem has been studied comprehensively in Economics...
متن کاملCournot Competition under Uncertainty∗
We analyze Cournot competition under demand uncertainty. We show that under rather general assumptions, the game has no asymmetric equilibria but multiple symmetric equilibria. Multiplicity is caused by the requirement of nonnegative prices and remains an issue also for simple demand specifications, such as the linear case. We then show that uniqueness of equilibrium is guaranteed if uncertaint...
متن کاملWelfare losses under Cournot competition
In a market for a homogeneous good where firms are identical, compete in quantities and produce with constant returns, the percentage of welfare losses (PWL) is small with as few as five competitors for a class of demand functions which includes linear and isoelastic cases. We study markets with positive fixed costs and asymmetric firms. We provide exact formulae of PWL and robust constructions...
متن کاملCournot Competition, Organization and Learning∗
We model firms’ output decisions in a repeated duopoly framework focussing on three interrelated issues: 1) the role of learning in the adjustment process toward equilibrium, 2) the role of organizational structure in organizational decision making, and 3) the role of changing environmental conditions on learning and output decisions. We model the firm as a type of artificial neural network, wh...
متن کاملBertrand and Cournot competition under asymmetric costs: number of active firms in equilibrium
We compare the number of active firms, i.e. the number of firms producing a positive quantity, in equilibrium across four different models of oligopoly: Cournot and Bertrand with homogeneous or differentiated goods. We concentrate on the linear demand structure with constant marginal but asymmetric costs. (With symmetric costs, the results trivialize to all firms active or all firms inactive.) ...
