Pricing Corporate Governance

CAMBRIDGE – Do markets appreciate and correctly price the corporate-governance provisions of companies? In new empirical research, Alma Cohen, Charles C.Y. Wang, and I show how stock markets have learned to price anti-takeover provisions. This learning by markets has important implications for both managements of publicly traded companies and their investors.

In 2001, three financial economists – Paul Gompers, Joy Ishii, and Andrew Metrick – identified a governance-based investment strategy that would have yielded superior stock-market returns during the 1990’s. The strategy was based on the presence of “entrenching” governance provisions, such as a classified board or a poison pill, which insulate managements from the discipline of the market for corporate control.
