Horizontal acquisitions affect prices through two channels: by eliminating competition between the firms involved, and by changing the incentives for collusion in the affected industry. This column summarises recent research that quantifies these two effects using a new methodology – one that accounts for the difference between financial interests and corporate control. A study of the disposable-razor industry shows that small firms have the greatest incentive to undercut pricing agreements. After acquisitions, acquiring firms have greater incentives to collude, whereas other firms in the industry are more likely to defect.
