A commitment device is a mechanism or arrangement that implements precommitment by deliberately restricting one’s own future options in order to make a commitment credible. In game theory, commitment devices are strategic moves that constrain an agent’s choices to influence an adversary or negotiating partner, as when a general burns bridges to make retreat impossible or a state adopts a nuclear deterrence posture that makes retaliation automatic. In behavioral economics, they are voluntary self-imposed constraints—such as savings accounts with withdrawal penalties or contracts that impose costs for failure—designed to help individuals follow through on intentions they might otherwise abandon due to akrasia or time-inconsistent preferences.
