Time and outcome framing in intertemporal tradeoffs.

Area of Science:

• Behavioral Economics
• Decision Science
• Cognitive Psychology

Background:

• Intertemporal choice exhibits a delay-speedup asymmetry, where people discount delayed receipts more than delayed payments.
• This asymmetry challenges standard economic models of discounting and decision-making under uncertainty.

Purpose of the Study:

• To develop and compare two tradeoff models explaining the delay-speedup asymmetry in intertemporal choice.
• To evaluate the predictive power of the outcome framing model and the novel time framing model.

Main Methods:

• Developed two versions of the tradeoff model: outcome framing and time framing.
• Compared model predictions against empirical data from matching (indifference) and choice (preference) tasks.

Main Results:

• The outcome framing model generalizes hyperbolic discounting, positing hypersensitivity to losses and hyposensitivity to gains.
• The time framing model frames timing changes as gains or losses of time, predicting hypersensitivity to time loss and hyposensitivity to time gain.
• The time framing model systematically outperformed the outcome framing model in predicting empirical data.

Conclusions:

• The time framing model provides a superior explanation for the delay-speedup asymmetry in intertemporal choice.
• Framing timing changes as gains or losses of time captures behavioral regularities more effectively than outcome framing.
