Time preferences in uncertain environment – field studies

I will present group of studies on time preference in uncertain environment.

The first two are field study on the time preferences of young adults of similar ages but in two very different environments, one more dangerous and uncertain than the other. Soldiers, college students and a control group of teenagers were asked to answer questionnaires regarding their time preferences. During mandatory service, soldiers live in a violent atmosphere where they face great uncertainty about the near future and high risk of mortality (measured by probability of survival). University students and teenagers, live in much calmer environment, and are tested for performance only periodically. The soldier-subjects show relatively high subjective discount rate when compared to the other two groups. We suggest that the higher subjective discount rate among soldiers can be the result of high perceived risk in the army “institution” or higher mortality risk.

The next study examines how a risky activity (e.g., skydiving) affects an individual’s time preference related to financial decisions (i.e., wanting to get paid before or after the activity). We found that prior to a risky activity, inexperienced people were more present-oriented, than they were afterwards. We suggest that the attempt to regulate concerns associated with activities individuals might find frightening affects unrelated, important daily decisions due to a shift in their time preference.

In the last study, we exposed subjects to visual priming for vacation and for old age in order to influence their time preference. The results indicate that our pictorial priming manipulations did affect time preference and subjective discount rates: vacation scenes increased present preference, and pictures of older people reduced present preference.
