This paper studies mergers in markets where firms invest in a portfolio of research projects of different profitability and social value. The portfolio nature of the investment problem brings about novel insights on the external effects of firms’ investments. The investment of a firm in one project imposes a negative business-stealing externality on the rival firms because it lowers the probability they win the innovation contest for that project; however, the investment of a firm in one project also exerts a positive business-giving externality on the rival firms because it increases the likelihood they win the contest for the alternative project.
