Measurement of Market Power Using Trademark Data: models, limitations and applications

ABSTRACT This paper analyzes the main models used to measure market power by means of brand data and verifies the advantages of the model developed by Cotterill, Franklin and Ma over the others. This is a very flexible model which can be used to any conjectural assumptions and allows the measurement of both unilateral and collusive market power. Several ways of application are suggested, and very promising perspectives are recognized for this type of study.

摘要 本文基于品牌数据分析了用于测度市场势力的主流模型，并验证了科特雷尔、富兰克林与马提出的模型相较于其他模型的优势。该模型具备极强的灵活性，可适配任意推测性假设，能够同时测度单边市场势力与合谋市场势力。本文提出了若干应用路径，并认为此类研究拥有极具潜力的发展前景。
