By Tingting Liu, Tao Shu and Jasmine Wang November 12, 2021 by renholding

The well-developed theory of the winner’s curse can potentially explain the poor performance of mergers and acquisitions (Roll, 1986). A key reason for the curse is the uncertainty concerning a deal’s value (e.g., Capen, Clapp, and Campbell, 1971; Bazerman and …
