Dynamic inconsistency (original) (raw)
In economics, dynamic inconsistency or time inconsistency is a situation in which a decision-maker's preferences change over time in such a way that a preference can become inconsistent at another point in time. This can be thought of as there being many different "selves" within decision makers, with each "self" representing the decision-maker at a different point in time; the inconsistency occurs when not all preferences are aligned. The term "dynamic inconsistency" is more closely affiliated with game theory, whereas "time inconsistency" is more closely affiliated with behavioral economics.

| dbo:abstract | In economics, dynamic inconsistency or time inconsistency is a situation in which a decision-maker's preferences change over time in such a way that a preference can become inconsistent at another point in time. This can be thought of as there being many different "selves" within decision makers, with each "self" representing the decision-maker at a different point in time; the inconsistency occurs when not all preferences are aligned. The term "dynamic inconsistency" is more closely affiliated with game theory, whereas "time inconsistency" is more closely affiliated with behavioral economics. (en) L'incohérence temporelle est une situation dans laquelle une politique économique décidée à un moment devient inutile quelque temps plus tard, souvent lorsqu'elle est entrée en œuvre. Il s'agit d'un concept utilisé en économie et en science politique. (fr) In economia l'incoerenza temporale, o incoerenza dinamica, descrive una situazione in cui le preferenze di un soggetto cambiano nel corso del tempo, in modo che ciò che è preferito in un certo momento non è coerente rispetto a ciò che è preferito in un altro istante. Spesso è più facile rappresentare le preferenze variabili nel tempo immaginando che i decisori siano costituiti da differenti "sé", ciascuno dei quali rappresenta il decisore a diversi istanti temporali. La teoria dell'incoerenza temporale è usata anche nella teoria dei giochi. (it) 在经济学中, 动态不一致 或时间不一致,描述一下情况:决策者的偏好随着时间而改变（按照某种特定的方式），导致他在某一时间的偏好和他在另一时间的偏好不一致。在这种情况下，通常把“在不同时间的偏好”想做“决策者是有好几个不同的“自我”组成，每个自我都代表一个特定时间的决策者”能够更容易理解。举个例子，这些自我可以有：今天的我、明天的我、下星期二的我、明年这个时候的我，等等。当某些个“我”的偏好和其他“我”的偏好不一致的时候，动态不一致就出现了。 有一种不一致和 博弈论联系更紧密, 这种情况下 "动态不一致"是通常使用的术语。另一种不一致和行为经济学联系更紧密,而在这种情况下 "时间 不一致"是通常使用的术语。 (zh) |
