Who Writes the Rules for Hostile Takeovers, and Why?

Event details of April 24, 2006: John Armour (University of Cambridge)
Date 24 April 2006
Time 11:45 -13:15


Hostile takeovers are commonly thought to play a key role in rendering managers accountable to dispersed shareholders in the ‘Anglo-American’ system of corporate governance. Yet surprisingly little attention has been paid to the very significant differences in takeover regulation between the two most prominent jurisdictions. In the UK, defensive tactics by target managers are prohibited, whereas Delaware law gives managers a good deal of room to maneuver. Existing accounts of this difference focus on alleged pathologies in competitive federalism in the US. In contrast, we focus on the ‘supply-side’ of rule production, by examining the evolution of the two regimes from a public choice perspective. We suggest that the content of the rules has been crucially influenced by differences in the mode of regulation. In the UK, selfregulation of takeovers has led to a regime largely driven by the interests of institutional investors, whereas the dynamics of judicial law-making in the US have made it relatively difficult for shareholders to influence the rules. Moreover, it was never possible for Wall Street to ‘privatize’ takeovers in the same way as the City of London, because US federal regulation in the ‘30s both pre-empted self-regulation and restricted the ability of institutional investors to coordinate.
