Time Inconsistency
Updated 2026-08-05
INTRODUCTION
English translation pending.
CORE DEFINITION
Time inconsistency describes the gap between what a decision-maker prefers at one moment and what it will prefer later. The core claim is that a policy chosen as optimal at time one often becomes tempting to abandon at time two, as when a government promises not to negotiate with kidnappers and then negotiates. Because the public anticipates this reversal, the promise loses credibility before it is ever tested. The qualification is that the problem is solved by removing future discretion, through independent central banks or smart contracts.
SCAFFOLDING EFFECT
Reduce cognitive load
- Credibility Trap: A promise without constraints is worth little, because the promiser keeps the option to reverse it. - Tying Hands: Independent central banks and smart contracts work by removing the ability to change one's mind later. - Commitment Device: Binding arrangements are the practical answer when future discretion would be used against you.
Anchor fast decisions
Preferences are inconsistent across time: the present self strongly prefers immediate reward while the future self prefers long-term benefit, so plans and execution drift apart. This is closely related to hyperbolic discounting, where the near term is weighted far more heavily than any later period.
