Sur la distribution bimodale du ratio de spécialisation des entreprises non financières

Author

Abstract

The bimodal distribution of the specialization ratio for large non-financial corporations has been a remarkable statistical regularity for forty years (Reed and Sharpe, 1987). The aim of this paper is first to provide an overview on the reality of this phenomenon over the period 1992-2007 in Europe and in the United States. Then, we try to identify some of the industrial dynamics which explain this distribution. We think here to the way the changes in the value of this ratio can be used to interpert the development strategies of firms in terms of diversification and refocusing
