Executive action that lasts.

Unilateral presidential action is thought to be limited by the ability of successors to easily reverse past decisions. Yet, most executive actions are never formally revoked. We argue that because of presidents' unique position as chief executive, some actions create outcomes that make policy reversal more difficult or even infeasible. We develop a novel measure of policies with more immutable consequences and analyze the revocation of executive orders issued between 1937 and 2021. We find the degree of outcome immutability reduces the influence of political conditions on policy revocation. We further examine these dynamics in three cases in which presidents have substantial discretion – diplomacy, non-combatant detention, and police militarization. Scholarship has long highlighted the president's first-mover status relative to other institutional actors as a key source of their power. Collectively, our argument and evidence demonstrate this applies to their relationship with successors. [ABSTRACT FROM AUTHOR]
