R. Rothschild, PETER F. SWANN, Majid Taghavi

Open publisher page 5 citations

Abstract

This paper develops a technique for identifying competitors from data on the correlations in the market shares of different firms. The technique is based on an application of a ‘complete system’ demand model, and results are presented graphically by an application of principal componens. The technique is illustrated with an example of competitors in the UK Commercial Vehicle Industry, and would be applicable to other markets.
