Agency Costs and Strategic Speculation in the U.S. Stock Market

Abstract

This study investigates the notion that agency-driven information asymmetry may affect a firm’s stock liquidity. I postulate that less uncertainty about managerial agency problems may enhance liquidity provision by lowering dealers’ perceived adverse selection risk from trading with better-informed speculators. Consistent with my conjecture, I find that the staggered adoption of antitakeover provisions across U.S. states in the 1980s and 1990s — a plausibly exogenous shock unambiguously reducing the threat of (and speculators’ information advantage about) value-enhancing intervention — robustly improves the stock liquidity of affected firms relative to peer firms, especially at prior high fundamental or agency uncertainty and with poor governance.
