The effects of vertical integration on competing input suppliers
McAfee, R. Preston (1999-01)
When a downstream firm buys an input supplier, it can reduce its costs of using that input. Other input suppliers typically respond by pricing more aggressively, given the demand reduction, which tends to lower input supply costs to other firms. Thus, a vertical merger may lower rivals' costs instead of raising them.
