Abstract
This paper derives testable implications of the standard Cournot models and confronts these implications with real world data. Though we cannot expect that real world may be characterized by a simple static homogeneous model, it is surprising that little empirical work exists on testing the implications of this most popular model of oligopoly and non cooperative game theory.
We make use of three data sets for manufacturing industry, two of them on the firm level, one about firms grouped according to their size. The relation of the results to the predictions of the Cournot model is discussed, as well as its relation to alternative oligopoly models. We specifically focus at the question whether the implications of the oligopoly models on the performance of large versus small firms are in line with the data.
