How much will I spend? Factors affecting consumers’ estimates of future expense

Investigates the effect of response alternatives used to elicit behavioral frequencies on subsequent estimates of future expense related to the behavior. Two experiments demonstrate that past and future expense estimates are affected by the range of response alternatives used to elicit a related behavioral frequency prior to eliciting the expense estimate. Exp 1 explored the extent to which past expenses will be used as a source of information to estimate future expenses as a function of the presence of response alternatives used to elicit behavioral frequency questions. Exp 1 also examined the effects of the range of response alternatives on estimated future expense. 90 undergraduate students participated in Exp 1. Exp 2 examined the effect of question sequencing on the manner in which past expense information vs the range of response alternatives are used to construct future expense estimates. 62 college students participated in Exp 2. Results show that future expense parallel the impact of response alternatives on behavioral frequency reports, providing evidence consistent with the proposition that estimates of future expenditure are partially based on estimates of behavioral frequency.
