Экономическая интеграция гетерогенных фирм: равновесие Курно-Нэша
The paper analyzes the process of economic integration of heterogeneous firms in the model of Cournot oligopoly. We generalize the symmetric model with standard assumptions of linear demand and the absence of free entry to the case of firms’ heterogeneity. Based on profitability criterion we derive the conclusions about merger efficiency under certain assumptions. In particular, it is proved that (i) the synergistic effect of the merger is not monotonic with respect to the number of integrating firms; (ii) for small size of merger the case where the most cost-effective company absorbs less efficient competitors gives the largest synergistic effect; (iii) for sufficiently large share of the merging firms the case when the merger involves the most cost-efficient firms is more profitable.
