Hard Marriage with Heavy Burdens: Organized Labor as Takeover Deterrents

Abstract

Abstract We examine how labor power affects a firm’s takeover exposure and merger gains. Using a regression discontinuity design that relies on “locally” exogenous variation in labor power generated by close-call union elections, we find that increased labor power significantly reduces a firm’s takeover exposure, reduces target offer premium and announcement returns, and prolongs deal completion duration. The results are stronger for more powerful and conflict-provoking unions. Bidders of unionized targets are experienced, are tough negotiators, and face fewer union threats by themselves. Our paper provides new insights into the real effects of shareholder-employee conflict regarding the market for corporate control.
