Commitment devices

Definition

Commitment devices are tools or strategies that help individuals stick to their long-term goals by restricting their future choices. These devices are used to counteract tendencies like procrastination and impulsive decision-making, often seen in intertemporal choices. By making certain future actions more difficult or costly, commitment devices help align short-term behavior with long-term objectives, particularly when preferences change over time.

1. Commitment devices can take many forms, such as contractual agreements, financial penalties, or even social commitments to friends or family.
2. They are particularly useful for individuals facing hyperbolic discounting, as they help manage the conflict between immediate gratification and long-term goals.
3. In sequential games, commitment devices can change the strategic landscape by allowing players to credibly commit to certain actions, influencing others' decisions.
4. Examples include setting up automatic savings plans or pre-committing to deadlines that make it harder to procrastinate on tasks.
5. The effectiveness of commitment devices often hinges on the degree of self-control an individual possesses and their awareness of potential future temptations.

Review Questions

• How do commitment devices help individuals facing hyperbolic discounting manage their long-term goals?
  • Commitment devices assist individuals who struggle with hyperbolic discounting by creating mechanisms that restrict their choices and align their short-term actions with long-term objectives. For example, by pre-committing to a savings plan or setting deadlines for tasks, individuals can counteract the temptation to prioritize immediate rewards over future gains. This helps ensure that they stay on track toward achieving their desired outcomes, despite their natural inclination to choose instant gratification.
• Discuss how commitment devices can affect strategic interactions in sequential games and lead to subgame perfect equilibria.
  • In sequential games, commitment devices allow players to make binding decisions that influence the strategies of other players throughout the game. By committing to a specific action or outcome, a player can change the expectations and responses of others, leading to a subgame perfect equilibrium where each player's strategy is optimal at every point in the game. This enhances strategic credibility and can lead to more favorable outcomes for the committing player by effectively shaping the game's dynamics.
• Evaluate the potential limitations of using commitment devices in real-world scenarios and their implications for self-control.
  • While commitment devices can be effective tools for enhancing self-control and achieving long-term goals, they are not without limitations. Individuals may find it challenging to maintain their commitments due to unforeseen circumstances or changes in motivation. Moreover, reliance on commitment devices could lead to a false sense of security regarding self-control, potentially resulting in greater impulsivity when these devices are not present. Understanding these limitations is crucial for effectively integrating commitment devices into personal goal-setting strategies and recognizing when alternative methods may be necessary.
