Doris Hildebrand, 'Using Conjoint Analysis for Market Definition: Application of Modern Market Research Tools to Implement the Hypothetical Monopolist Test' (2006) 29 World Competition, Issue 2, pp. 315–335


Market definition is instrumental to the assessment of market power and central to competition policy. Until recently, the assessment of market boundaries has been primarily a qualitative judgemental process. However, the past years have not only seen the development of new quantitative methods of defining markets, but also a growing demand for these econometric methods. This article discusses some of the issues arising in the empirical implementation of the Hypothetical Monopolist Test by econometric tools. In particular, the article shows how a certain empirical methodology which has found broad acceptance in market research, Conjoint Analysis, can be applied to market definition
