Timing and Self-Control
研究标准双自我模型对决策时机和中间无行动期的过度敏感问题,通过引入非完全短视的短期自我和认知资源变量来解决,并分析消费机会的避免或延迟。
The standard dual-self model of self-control, with a shorter-run self who cares only about the current period, is excessively sensitive to the timing of decisions and to the interpolation of additional "no-action" time periods in between the dates when decisions are made.We show that when the shorter-run self is not completely myopic, this excess sensitivity goes away.To accommodate the combination of short time periods and convex costs of self-control, we introduce a cognitive resource variable that tracks how the control cost depends on the self-control that has been used in the recent past.We consider models with both linear and convex control costs, illustrating the theory through a series of examples.We examine when opportunities to consume will be avoided or delayed, and we consider the way in which the marginal interest declines with delay.
