[Structure] P1: Raise the question: what cause the diversification waves? P2: The old explanation “antitrust hypothesis” but has skeptics. P3: The purpose of this paper: make an empirical assessment of AH. If AH was right, diversification should be different among large and small mergers, but there was no statistical evidence. P4: The author also examined diversification patterns in different countries and proved that antitrust was not the cause. Reason 1: No legal restrictions but also have diversification waves. P5: Reason 2: Increasing diversification widely exists in Western countries while legal restrictions were unique to U.S. P6: Evidences of mergers in Britain. P7: Evidences of mergers in Canada.
