| | Oxford Scholarship Online: Strategic Interaction and Markets |
 | | Abstract: Perfect competition provides a model of a frictionless economy in which economic agents behave independently of each other, abandoning to the market the task of coordinating their individual decisions. |
 | | This model is extensively studied in traditional price theory textbooks.Imperfect competition is the paradigm that develops when, on the contrary, economic agents interact in a conscious manner, which is necessarily the case when competition takes place ‘among the few’. |
 | | The four assumptions underlying the paradigm of perfect competition (no barriers to entry, large number of agents, product homogeneity, and perfect information) constitute the natural departure points of the theories of imperfect competition: whenever at least one of these assumptions is violated, imperfect competition is present. |
