رقبای تهدید آمیز - ادغام عمودی درونی و سرمایه گذاری پایین دست در انحصار چند جانبه متوالی

This paper examines the interplay of endogenous vertical integration and cost-reducing downstream investment in successive oligopoly. Analyzing a linear Cournot model, we establish the following key results: (i) Vertical integration increases own investment and decreases competitor investment (intimidation effect). (ii) Asymmetric integration is a non-degenerate equilibrium outcome. (iii) Compared to a benchmark model without investment, complete vertical separation is a less likely outcome. We argue that these findings generalize beyond the linear Cournot model under reasonable assumptions.
