Using mutual fund redemptions as an instrument for price changes, we identify a strong effect of market prices on takeover activity (the "trigger effect"). An interquartile decrease in valuation leads to a seven percentage point increase in acquisition likelihood, relative to a 6% unconditional takeover probability. Instrumentation addresses the fact that prices are endogenous and increase in anticipation of a takeover (the "anticipation effect"). Our results overturn prior literature that finds a weak relation between prices and takeovers without instrumentation. These findings imply that financial markets have real effects: They impose discipline on managers by triggering takeover threats.DOES A LOW MARKET valuation make a firm a takeover target? In theory, if acquisition prices are related to market prices, acquirers can profit from taking over a firm whose market value is low relative to its peers-due either to mispricing or mismanagement-and restore it to its potential. Indeed, in practice, acquirers and other investors appear to track a firm's valuation multiples for indications on the potential for acquisition, and managers strive to maintain high market valuations to prevent a hostile takeover. Understanding whether such a link exists is important because, if so, this would suggest that the market is not a sideshow, but rather exerts a powerful disciplinary effect on firm management (as suggested by Marris (1964), Manne (1965), andJensen (1993)).Despite the above logic, existing empirical studies on takeovers fail to systematically uncover a meaningful relationship between market valuations * Edmans is from The Wharton School, University of Pennsylvania, NBER, and ECGI.
